-
-# Building the registry source
-
-## Use-case
-
-This is useful if you intend to actively work on the registry.
-
-### Alternatives
-
-Most people should use the [official Registry docker image](https://hub.docker.com/r/library/registry/).
-
-People looking for advanced operational use cases might consider rolling their own image with a custom Dockerfile inheriting `FROM registry:2`.
-
-OS X users who want to run natively can do so following [the instructions here](https://github.com/docker/docker.github.io/blob/master/registry/recipes/osx-setup-guide.md).
-
-### Gotchas
-
-You are expected to know your way around with go & git.
-
-If you are a casual user with no development experience, and no preliminary knowledge of go, building from source is probably not a good solution for you.
-
-## Build the development environment
-
-The first prerequisite of properly building distribution targets is to have a Go
-development environment setup. Please follow [How to Write Go Code](https://golang.org/doc/code.html)
-for proper setup. If done correctly, you should have a GOROOT and GOPATH set in the
-environment.
-
-If a Go development environment is setup, one can use `go get` to install the
-`registry` command from the current latest:
-
-    go get github.com/docker/distribution/cmd/registry
-
-The above will install the source repository into the `GOPATH`.
-
-Now create the directory for the registry data (this might require you to set permissions properly)
-
-    mkdir -p /var/lib/registry
-
-... or alternatively `export REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/somewhere` if you want to store data into another location.
-
-The `registry`
-binary can then be run with the following:
-
-    $ $GOPATH/bin/registry --version
-    $GOPATH/bin/registry github.com/docker/distribution v2.0.0-alpha.1+unknown
-
-> __NOTE:__ While you do not need to use `go get` to checkout the distribution
-> project, for these build instructions to work, the project must be checked
-> out in the correct location in the `GOPATH`. This should almost always be
-> `$GOPATH/src/github.com/docker/distribution`.
-
-The registry can be run with the default config using the following
-incantation:
-
-    $ $GOPATH/bin/registry serve $GOPATH/src/github.com/docker/distribution/cmd/registry/config-example.yml
-    INFO[0000] endpoint local-5003 disabled, skipping        app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
-    INFO[0000] endpoint local-8083 disabled, skipping        app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
-    INFO[0000] listening on :5000                            app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
-    INFO[0000] debug server listening localhost:5001
-
-If it is working, one should see the above log messages.
-
-### Repeatable Builds
-
-For the full development experience, one should `cd` into
-`$GOPATH/src/github.com/docker/distribution`. From there, the regular `go`
-commands, such as `go test`, should work per package (please see
-[Developing](#developing) if they don't work).
-
-A `Makefile` has been provided as a convenience to support repeatable builds.
-Please install the following into `GOPATH` for it to work:
-
-    go get github.com/golang/lint/golint
-
-Once these commands are available in the `GOPATH`, run `make` to get a full
-build:
-
-    $ make
-    + clean
-    + fmt
-    + vet
-    + lint
-    + build
-    github.com/docker/docker/vendor/src/code.google.com/p/go/src/pkg/archive/tar
-    github.com/sirupsen/logrus
-    github.com/docker/libtrust
-    ...
-    github.com/yvasiyarov/gorelic
-    github.com/docker/distribution/registry/handlers
-    github.com/docker/distribution/cmd/registry
-    + test
-    ...
-    ok    github.com/docker/distribution/digest 7.875s
-    ok    github.com/docker/distribution/manifest 0.028s
-    ok    github.com/docker/distribution/notifications  17.322s
-    ?     github.com/docker/distribution/registry [no test files]
-    ok    github.com/docker/distribution/registry/api/v2  0.101s
-    ?     github.com/docker/distribution/registry/auth  [no test files]
-    ok    github.com/docker/distribution/registry/auth/silly  0.011s
-    ...
-    + /Users/sday/go/src/github.com/docker/distribution/bin/registry
-    + /Users/sday/go/src/github.com/docker/distribution/bin/registry-api-descriptor-template
-    + binaries
-
-The above provides a repeatable build using the contents of the vendor
-directory. This includes formatting, vetting, linting, building,
-testing and generating tagged binaries. We can verify this worked by running
-the registry binary generated in the "./bin" directory:
-
-    $ ./bin/registry --version
-    ./bin/registry github.com/docker/distribution v2.0.0-alpha.2-80-g16d8b2c.m
-
-### Optional build tags
-
-Optional [build tags](http://golang.org/pkg/go/build/) can be provided using
-the environment variable `DOCKER_BUILDTAGS`.

 # Contributing to the registry
 
-## Before reporting an issue...
+## Are you having issues?
 
-### If your problem is with...
+Please first try any of these support forums before opening an issue:
 
- - automated builds or your [Docker Hub](https://hub.docker.com/) account
+ * irc #docker on freenode (archives: [https://botbot.me/freenode/docker/])
-   - Report it to [Hub Support](https://hub.docker.com/support/)
+ * https://forums.docker.com/
- - Distributions of Docker for desktop or Linux
+ * if your problem is with the "hub" (the website and other user-facing components), or about automated builds, then please direct your issues to https://support.docker.com
-    - Report [Mac Desktop issues](https://github.com/docker/for-mac)
-    - Report [Windows Desktop issues](https://github.com/docker/for-win)
-    - Report [Linux issues](https://github.com/docker/for-linux)
 
-### If you...
+## So, you found a bug?
 
- - need help setting up your registry
+First check if your problem was already reported in the issue tracker.
- - can't figure out something
- - are not sure what's going on or what your problem is
 
-Please ask first in the #distribution channel on Docker community slack.
+If it's already there, please refrain from adding "same here" comments - these don't add any value and are only adding useless noise. **Said comments will quite often be deleted at sight**. On the other hand, if you have any technical, relevant information to add, by all means do!
-[Click here for an invite to Docker community slack](https://dockr.ly/slack)
 
-### Reporting security issues
+Your issue is not there? Then please, create a ticket.
 
-The Docker maintainers take security seriously. If you discover a security
+If possible the following guidelines should be followed:
-issue, please bring it to their attention right away!
 
-Please **DO NOT** file a public issue, instead send your report privately to
+ * try to come up with a minimal, simple to reproduce test-case
-[security@docker.com](mailto:security@docker.com).
+ * try to add a title that describe succinctly the issue
+ * if you are running your own registry, please provide:
+  * registry version
+  * registry launch command used
+  * registry configuration
+  * registry logs
+ * in all cases:
+  * `docker version` and `docker info`
+  * run your docker daemon in debug mode (-D), and provide docker daemon logs 
 
-## Reporting an issue properly
+## You have a patch for a known bug, or a small correction?
 
-By following these simple rules you will get better and faster feedback on your issue.
+Basic github workflow (fork, patch, make sure the tests pass, PR).
 
- - search the bugtracker for an already reported issue
+... and some simple rules to ensure quick merge:
 
-### If you found an issue that describes your problem:
+ * clearly point to the issue(s) you want to fix
+ * when possible, prefer multiple (smaller) PRs addressing individual issues over a big one trying to address multiple issues at once
+ * if you need to amend your PR following comments, squash instead of adding more commits
 
- - please read other user comments first, and confirm this is the same issue: a given error condition might be indicative of different problems - you may also find a workaround in the comments
+## You want some shiny new feature to be added?
- - please refrain from adding "same thing here" or "+1" comments
- - you don't need to comment on an issue to get notified of updates: just hit the "subscribe" button
- - comment if you have some new, technical and relevant information to add to the case
- - __DO NOT__ comment on closed issues or merged PRs. If you think you have a related problem, open up a new issue and reference the PR or issue.
 
-### If you have not found an existing issue that describes your problem:
+Fork the project.
 
- 1. create a new issue, with a succinct title that describes your issue:
+Create a new proposal in the folder `open-design/specs`, named `DEP_MY_AWESOME_PROPOSAL.md`, using `open-design/specs/TEMPLATE.md` as a starting point.
-   - bad title: "It doesn't work with my docker"
-   - good title: "Private registry push fail: 400 error with E_INVALID_DIGEST"
- 2. copy the output of:
-   - `docker version`
-   - `docker info`
-   - `docker exec <registry-container> registry --version`
- 3. copy the command line you used to launch your Registry
- 4. restart your docker daemon in debug mode (add `-D` to the daemon launch arguments)
- 5. reproduce your problem and get your docker daemon logs showing the error
- 6. if relevant, copy your registry logs that show the error
- 7. provide any relevant detail about your specific Registry configuration (e.g., storage backend used)
- 8. indicate if you are using an enterprise proxy, Nginx, or anything else between you and your Registry
 
-## Contributing Code
+Then immediately submit this new file as a pull-request, in order to get early feedback.
 
-Contributions should be made via pull requests. Pull requests will be reviewed
+Eventually, you will have to update your proposal to accommodate the feedback you received.
-by one or more maintainers or reviewers and merged when acceptable.
 
-You should follow the basic GitHub workflow:
+Usually, it's not advisable to start working too much on the implementation itself before the proposal receives sufficient feedback, since it can significantly altered (or rejected).
 
- 1. Use your own [fork](https://help.github.com/en/articles/about-forks)
+Your implementation should then be submitted as a separate PR, that will be reviewed as well.
- 2. Create your [change](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
- 3. Test your code
- 4. [Commit](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages) your work, always [sign your commits](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#commit-messages)
- 5. Push your change to your fork and create a [Pull Request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork)
-
-Refer to [containerd's contribution guide](https://github.com/containerd/project/blob/master/CONTRIBUTING.md#successful-changes)
-for tips on creating a successful contribution.
-
-## Sign your work
-
-The sign-off is a simple line at the end of the explanation for the patch. Your
-signature certifies that you wrote the patch or otherwise have the right to pass
-it on as an open-source patch. The rules are pretty simple: if you can certify
-the below (from [developercertificate.org](http://developercertificate.org/)):
-
-```
-Developer Certificate of Origin
-Version 1.1
-
-Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
-660 York Street, Suite 102,
-San Francisco, CA 94110 USA
-
-Everyone is permitted to copy and distribute verbatim copies of this
-license document, but changing it is not allowed.
-
-Developer's Certificate of Origin 1.1
-
-By making a contribution to this project, I certify that:
-
-(a) The contribution was created in whole or in part by me and I
-    have the right to submit it under the open source license
-    indicated in the file; or
-
-(b) The contribution is based upon previous work that, to the best
-    of my knowledge, is covered under an appropriate open source
-    license and I have the right under that license to submit that
-    work with modifications, whether created in whole or in part
-    by me, under the same open source license (unless I am
-    permitted to submit under a different license), as indicated
-    in the file; or
-
-(c) The contribution was provided directly to me by some other
-    person who certified (a), (b) or (c) and I have not modified
-    it.
-
-(d) I understand and agree that this project and the contribution
-    are public and that a record of the contribution (including all
-    personal information I submit with it, including my sign-off) is
-    maintained indefinitely and may be redistributed consistent with
-    this project or the open source license(s) involved.
-```
-
-Then you just add a line to every git commit message:
-
-    Signed-off-by: Joe Smith <joe.smith@email.com>
-
-Use your real name (sorry, no pseudonyms or anonymous contributions.)
-
-If you set your `user.name` and `user.email` git configs, you can sign your
-commit automatically with `git commit -s`.

-# docker/distribution Project Governance
-
-Docker distribution abides by the [CNCF Code of Conduct](https://github.com/cncf/foundation/blob/master/code-of-conduct.md).
-
-For specific guidance on practical contribution steps please
-see our [CONTRIBUTING.md](./CONTRIBUTING.md) guide.
-
-## Maintainership
-
-There are different types of maintainers, with different responsibilities, but
-all maintainers have 3 things in common:
-
-1) They share responsibility in the project's success.
-2) They have made a long-term, recurring time investment to improve the project.
-3) They spend that time doing whatever needs to be done, not necessarily what
-is the most interesting or fun.
-
-Maintainers are often under-appreciated, because their work is harder to appreciate.
-It's easy to appreciate a really cool and technically advanced feature. It's harder
-to appreciate the absence of bugs, the slow but steady improvement in stability,
-or the reliability of a release process. But those things distinguish a good
-project from a great one.
-
-## Reviewers
-
-A reviewer is a core role within the project.
-They share in reviewing issues and pull requests and their LGTM counts towards the
-required LGTM count to merge a code change into the project.
-
-Reviewers are part of the organization but do not have write access.
-Becoming a reviewer is a core aspect in the journey to becoming a maintainer.
-
-## Adding maintainers
-
-Maintainers are first and foremost contributors that have shown they are
-committed to the long term success of a project. Contributors wanting to become
-maintainers are expected to be deeply involved in contributing code, pull
-request review, and triage of issues in the project for more than three months.
-
-Just contributing does not make you a maintainer, it is about building trust
-with the current maintainers of the project and being a person that they can
-depend on and trust to make decisions in the best interest of the project.
-
-Periodically, the existing maintainers curate a list of contributors that have
-shown regular activity on the project over the prior months. From this list,
-maintainer candidates are selected and proposed in a pull request or a
-maintainers communication channel.
-
-After a candidate has been announced to the maintainers, the existing
-maintainers are given five business days to discuss the candidate, raise
-objections and cast their vote. Votes may take place on the communication
-channel or via pull request comment. Candidates must be approved by at least 66%
-of the current maintainers by adding their vote on the mailing list. The
-reviewer role has the same process but only requires 33% of current maintainers.
-Only maintainers of the repository that the candidate is proposed for are
-allowed to vote.
-
-If a candidate is approved, a maintainer will contact the candidate to invite
-the candidate to open a pull request that adds the contributor to the
-MAINTAINERS file. The voting process may take place inside a pull request if a
-maintainer has already discussed the candidacy with the candidate and a
-maintainer is willing to be a sponsor by opening the pull request. The candidate
-becomes a maintainer once the pull request is merged.
-
-## Stepping down policy
-
-Life priorities, interests, and passions can change. If you're a maintainer but
-feel you must remove yourself from the list, inform other maintainers that you
-intend to step down, and if possible, help find someone to pick up your work.
-At the very least, ensure your work can be continued where you left off.
-
-After you've informed other maintainers, create a pull request to remove
-yourself from the MAINTAINERS file.
-
-## Removal of inactive maintainers
-
-Similar to the procedure for adding new maintainers, existing maintainers can
-be removed from the list if they do not show significant activity on the
-project. Periodically, the maintainers review the list of maintainers and their
-activity over the last three months.
-
-If a maintainer has shown insufficient activity over this period, a neutral
-person will contact the maintainer to ask if they want to continue being
-a maintainer. If the maintainer decides to step down as a maintainer, they
-open a pull request to be removed from the MAINTAINERS file.
-
-If the maintainer wants to remain a maintainer, but is unable to perform the
-required duties they can be removed with a vote of at least 66% of the current
-maintainers. In this case, maintainers should first propose the change to
-maintainers via the maintainers communication channel, then open a pull request
-for voting. The voting period is five business days. The voting pull request
-should not come as a surpise to any maintainer and any discussion related to
-performance must not be discussed on the pull request.
-
-## How are decisions made?
-
-Docker distribution is an open-source project with an open design philosophy.
-This means that the repository is the source of truth for EVERY aspect of the
-project, including its philosophy, design, road map, and APIs. *If it's part of
-the project, it's in the repo. If it's in the repo, it's part of the project.*
-
-As a result, all decisions can be expressed as changes to the repository. An
-implementation change is a change to the source code. An API change is a change
-to the API specification. A philosophy change is a change to the philosophy
-manifesto, and so on.
-
-All decisions affecting distribution, big and small, follow the same 3 steps:
-
-* Step 1: Open a pull request. Anyone can do this.
-
-* Step 2: Discuss the pull request. Anyone can do this.
-
-* Step 3: Merge or refuse the pull request. Who does this depends on the nature
-of the pull request and which areas of the project it affects.
-
-## Helping contributors with the DCO
-
-The [DCO or `Sign your work`](./CONTRIBUTING.md#sign-your-work)
-requirement is not intended as a roadblock or speed bump.
-
-Some contributors are not as familiar with `git`, or have used a web
-based editor, and thus asking them to `git commit --amend -s` is not the best
-way forward.
-
-In this case, maintainers can update the commits based on clause (c) of the DCO.
-The most trivial way for a contributor to allow the maintainer to do this, is to
-add a DCO signature in a pull requests's comment, or a maintainer can simply
-note that the change is sufficiently trivial that it does not substantially
-change the existing contribution - i.e., a spelling change.
-
-When you add someone's DCO, please also add your own to keep a log.
-
-## I'm a maintainer. Should I make pull requests too?
-
-Yes. Nobody should ever push to master directly. All changes should be
-made through a pull request.
-
-## Conflict Resolution
-
-If you have a technical dispute that you feel has reached an impasse with a
-subset of the community, any contributor may open an issue, specifically
-calling for a resolution vote of the current core maintainers to resolve the
-dispute. The same voting quorums required (2/3) for adding and removing
-maintainers will apply to conflict resolution.

+# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>&nbsp;[![Build Status](https://travis-ci.org/Sirupsen/logrus.svg?branch=master)](https://travis-ci.org/Sirupsen/logrus)
+
+Logrus is a structured logger for Go (golang), completely API compatible with
+the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
+yet stable (pre 1.0), the core API is unlikely change much but please version
+control your Logrus to make sure you aren't fetching latest `master` on every
+build.**
+
+Nicely color-coded in development (when a TTY is attached, otherwise just
+plain text):
+
+![Colored](http://i.imgur.com/PY7qMwd.png)
+
+With `log.Formatter = new(logrus.JSONFormatter)`, for easy parsing by logstash
+or Splunk:
+
+```json
+{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
+ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
+
+{"level":"warning","msg":"The group's number increased tremendously!",
+"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
+
+{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
+"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
+
+{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
+"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
+
+{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
+"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
+```
+
+With the default `log.Formatter = new(logrus.TextFormatter)` when a TTY is not
+attached, the output is compatible with the
+[l2met](http://r.32k.io/l2met-introduction) format:
+
+```text
+time="2014-04-20 15:36:23.830442383 -0400 EDT" level="info" msg="A group of walrus emerges from the ocean" animal="walrus" size=10
+time="2014-04-20 15:36:23.830584199 -0400 EDT" level="warning" msg="The group's number increased tremendously!" omg=true number=122
+time="2014-04-20 15:36:23.830596521 -0400 EDT" level="info" msg="A giant walrus appears!" animal="walrus" size=10
+time="2014-04-20 15:36:23.830611837 -0400 EDT" level="info" msg="Tremendously sized cow enters the ocean." animal="walrus" size=9
+time="2014-04-20 15:36:23.830626464 -0400 EDT" level="fatal" msg="The ice breaks!" omg=true number=100
+```
+
+#### Example
+
+The simplest way to use Logrus is simply the package-level exported logger:
+
+```go
+package main
+
+import (
+  log "github.com/Sirupsen/logrus"
+)
+
+func main() {
+  log.WithFields(log.Fields{
+    "animal": "walrus",
+  }).Info("A walrus appears")
+}
+```
+
+Note that it's completely api-compatible with the stdlib logger, so you can
+replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
+and you'll now have the flexibility of Logrus. You can customize it all you
+want:
+
+```go
+package main
+
+import (
+  "os"
+  log "github.com/Sirupsen/logrus"
+  "github.com/Sirupsen/logrus/hooks/airbrake"
+)
+
+func init() {
+  // Log as JSON instead of the default ASCII formatter.
+  log.SetFormatter(&log.JSONFormatter{})
+
+  // Use the Airbrake hook to report errors that have Error severity or above to
+  // an exception tracker. You can create custom hooks, see the Hooks section.
+  log.AddHook(&logrus_airbrake.AirbrakeHook{})
+
+  // Output to stderr instead of stdout, could also be a file.
+  log.SetOutput(os.Stderr)
+
+  // Only log the warning severity or above.
+  log.SetLevel(log.WarnLevel)
+}
+
+func main() {
+  log.WithFields(log.Fields{
+    "animal": "walrus",
+    "size":   10,
+  }).Info("A group of walrus emerges from the ocean")
+
+  log.WithFields(log.Fields{
+    "omg":    true,
+    "number": 122,
+  }).Warn("The group's number increased tremendously!")
+
+  log.WithFields(log.Fields{
+    "omg":    true,
+    "number": 100,
+  }).Fatal("The ice breaks!")
+}
+```
+
+For more advanced usage such as logging to multiple locations from the same
+application, you can also create an instance of the `logrus` Logger:
+
+```go
+package main
+
+import (
+  "github.com/Sirupsen/logrus"
+)
+
+// Create a new instance of the logger. You can have any number of instances.
+var log = logrus.New()
+
+func main() {
+  // The API for setting attributes is a little different than the package level
+  // exported logger. See Godoc.
+  log.Out = os.Stderr
+
+  log.WithFields(logrus.Fields{
+    "animal": "walrus",
+    "size":   10,
+  }).Info("A group of walrus emerges from the ocean")
+}
+```
+
+#### Fields
+
+Logrus encourages careful, structured logging though logging fields instead of
+long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
+to send event %s to topic %s with key %d")`, you should log the much more
+discoverable:
+
+```go
+log.WithFields(log.Fields{
+  "event": event,
+  "topic": topic,
+  "key": key,
+}).Fatal("Failed to send event")
+```
+
+We've found this API forces you to think about logging in a way that produces
+much more useful logging messages. We've been in countless situations where just
+a single added field to a log statement that was already there would've saved us
+hours. The `WithFields` call is optional.
+
+In general, with Logrus using any of the `printf`-family functions should be
+seen as a hint you should add a field, however, you can still use the
+`printf`-family functions with Logrus.
+
+#### Hooks
+
+You can add hooks for logging levels. For example to send errors to an exception
+tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
+multiple places simultaneously, e.g. syslog.
+
+```go
+// Not the real implementation of the Airbrake hook. Just a simple sample.
+import (
+  log "github.com/Sirupsen/logrus"
+)
+
+func init() {
+  log.AddHook(new(AirbrakeHook))
+}
+
+type AirbrakeHook struct{}
+
+// `Fire()` takes the entry that the hook is fired for. `entry.Data[]` contains
+// the fields for the entry. See the Fields section of the README.
+func (hook *AirbrakeHook) Fire(entry *logrus.Entry) error {
+  err := airbrake.Notify(entry.Data["error"].(error))
+  if err != nil {
+    log.WithFields(log.Fields{
+      "source":   "airbrake",
+      "endpoint": airbrake.Endpoint,
+    }).Info("Failed to send error to Airbrake")
+  }
+
+  return nil
+}
+
+// `Levels()` returns a slice of `Levels` the hook is fired for.
+func (hook *AirbrakeHook) Levels() []log.Level {
+  return []log.Level{
+    log.ErrorLevel,
+    log.FatalLevel,
+    log.PanicLevel,
+  }
+}
+```
+
+Logrus comes with built-in hooks. Add those, or your custom hook, in `init`:
+
+```go
+import (
+  log "github.com/Sirupsen/logrus"
+  "github.com/Sirupsen/logrus/hooks/airbrake"
+  "github.com/Sirupsen/logrus/hooks/syslog"
+  "log/syslog"
+)
+
+func init() {
+  log.AddHook(new(logrus_airbrake.AirbrakeHook))
+
+  hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
+  if err != nil {
+    log.Error("Unable to connect to local syslog daemon")
+  } else {
+    log.AddHook(hook)
+  }
+}
+```
+
+* [`github.com/Sirupsen/logrus/hooks/airbrake`](https://github.com/Sirupsen/logrus/blob/master/hooks/airbrake/airbrake.go)
+  Send errors to an exception tracking service compatible with the Airbrake API.
+  Uses [`airbrake-go`](https://github.com/tobi/airbrake-go) behind the scenes.
+
+* [`github.com/Sirupsen/logrus/hooks/papertrail`](https://github.com/Sirupsen/logrus/blob/master/hooks/papertrail/papertrail.go)
+  Send errors to the Papertrail hosted logging service via UDP.
+
+* [`github.com/Sirupsen/logrus/hooks/syslog`](https://github.com/Sirupsen/logrus/blob/master/hooks/syslog/syslog.go)
+  Send errors to remote syslog server.
+  Uses standard library `log/syslog` behind the scenes.
+
+* [`github.com/nubo/hiprus`](https://github.com/nubo/hiprus)
+  Send errors to a channel in hipchat.
+
+#### Level logging
+
+Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
+
+```go
+log.Debug("Useful debugging information.")
+log.Info("Something noteworthy happened!")
+log.Warn("You should probably take a look at this.")
+log.Error("Something failed but I'm not quitting.")
+// Calls os.Exit(1) after logging
+log.Fatal("Bye.")
+// Calls panic() after logging
+log.Panic("I'm bailing.")
+```
+
+You can set the logging level on a `Logger`, then it will only log entries with
+that severity or anything above it:
+
+```go
+// Will log anything that is info or above (warn, error, fatal, panic). Default.
+log.SetLevel(log.InfoLevel)
+```
+
+It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
+environment if your application has that.
+
+#### Entries
+
+Besides the fields added with `WithField` or `WithFields` some fields are
+automatically added to all logging events:
+
+1. `time`. The timestamp when the entry was created.
+2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
+   the `AddFields` call. E.g. `Failed to send event.`
+3. `level`. The logging level. E.g. `info`.
+
+#### Environments
+
+Logrus has no notion of environment.
+
+If you wish for hooks and formatters to only be used in specific environments,
+you should handle that yourself. For example, if your application has a global
+variable `Environment`, which is a string representation of the environment you
+could do:
+
+```go
+import (
+  log "github.com/Sirupsen/logrus"
+)
+
+init() {
+  // do something here to set environment depending on an environment variable
+  // or command-line flag
+  if Environment == "production" {
+    log.SetFormatter(logrus.JSONFormatter)
+  } else {
+    // The TextFormatter is default, you don't actually have to do this.
+    log.SetFormatter(logrus.TextFormatter)
+  }
+}
+```
+
+This configuration is how `logrus` was intended to be used, but JSON in
+production is mostly only useful if you do log aggregation with tools like
+Splunk or Logstash.
+
+#### Formatters
+
+The built-in logging formatters are:
+
+* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
+  without colors.
+  * *Note:* to force colored output when there is no TTY, set the `ForceColors`
+    field to `true`.  To force no colored output even if there is a TTY  set the
+    `DisableColors` field to `true`
+* `logrus.JSONFormatter`. Logs fields as JSON.
+
+Third party logging formatters:
+
+* [`zalgo`](https://github.com/aybabtme/logzalgo): invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
+
+You can define your formatter by implementing the `Formatter` interface,
+requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
+`Fields` type (`map[string]interface{}`) with all your fields as well as the
+default ones (see Entries section above):
+
+```go
+type MyJSONFormatter struct {
+}
+
+log.SetFormatter(new(MyJSONFormatter))
+
+func (f *JSONFormatter) Format(entry *Entry) ([]byte, error) {
+  // Note this doesn't include Time, Level and Message which are available on
+  // the Entry. Consult `godoc` on information about those fields or read the
+  // source of the official loggers.
+  serialized, err := json.Marshal(entry.Data)
+    if err != nil {
+      return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
+    }
+  return append(serialized, '\n'), nil
+}
+```
+
+#### Rotation
+
+Log rotation is not provided with Logrus. Log rotation should be done by an
+external program (like `logrotated(8)`) that can compress and delete old log
+entries. It should not be a feature of the application-level logger.

+# Papertrail Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
+
+[Papertrail](https://papertrailapp.com) provides hosted log management. Once stored in Papertrail, you can [group](http://help.papertrailapp.com/kb/how-it-works/groups/) your logs on various dimensions, [search](http://help.papertrailapp.com/kb/how-it-works/search-syntax) them, and trigger [alerts](http://help.papertrailapp.com/kb/how-it-works/alerts).
+
+In most deployments, you'll want to send logs to Papertrail via their [remote_syslog](http://help.papertrailapp.com/kb/configuration/configuring-centralized-logging-from-text-log-files-in-unix/) daemon, which requires no application-specific configuration. This hook is intended for relatively low-volume logging, likely in managed cloud hosting deployments where installing `remote_syslog` is not possible.
+
+## Usage
+
+You can find your Papertrail UDP port on your [Papertrail account page](https://papertrailapp.com/account/destinations). Substitute it below for `YOUR_PAPERTRAIL_UDP_PORT`.
+
+For `YOUR_APP_NAME`, substitute a short string that will readily identify your application or service in the logs.

+# Sentry Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
+
+[Sentry](https://getsentry.com) provides both self-hosted and hosted
+solutions for exception tracking.
+Both client and server are
+[open source](https://github.com/getsentry/sentry).
+
+## Usage
+
+Every sentry application defined on the server gets a different
+[DSN](https://www.getsentry.com/docs/). In the example below replace
+`YOUR_DSN` with the one created for your application.
+
+```go
+import (
+  "github.com/Sirupsen/logrus"
+  "github.com/Sirupsen/logrus/hooks/sentry"
+)
+
+func main() {
+  log       := logrus.New()
+  hook, err := logrus_sentry.NewSentryHook(YOUR_DSN, []logrus.Level{
+    logrus.PanicLevel,
+    logrus.FatalLevel,
+    logrus.ErrorLevel,
+  })
+
+  if err == nil {
+    log.Hooks.Add(hook)
+  }
+}
+```
+
+## Special fields
+
+Some logrus fields have a special meaning in this hook,
+these are server_name and logger.
+When logs are sent to sentry these fields are treated differently.
+- server_name (also known as hostname) is the name of the server which
+is logging the event (hostname.example.com)
+- logger is the part of the application which is logging the event.
+In go this usually means setting it to the name of the package.
+
+## Timeout
+
+`Timeout` is the time the sentry hook will wait for a response
+from the sentry server.
+
+If this time elapses with no response from
+the server an error will be returned.
+
+If `Timeout` is set to 0 the SentryHook will not wait for a reply
+and will assume a correct delivery.
+
+The SentryHook has a default timeout of `100 milliseconds` when created
+with a call to `NewSentryHook`. This can be changed by assigning a value to the `Timeout` field:
+
+```go
+hook, _ := logrus_sentry.NewSentryHook(...)
+hook.Timeout = 20*time.Seconds
+```
