# GitHub Actions Workflows
|
||||
|
||||
## Setup
|
||||
- workloads run using [GitHub self-hosted runners](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners)
|
||||
- project admins maintain a private Google Compute Engine VM for running tests
|
||||
- VM should be at least n1-standard-4 with 50GB persistent disk
|
||||
- instructions for setting up the VM can be found in repo settings under "Actions"
|
||||
- ⚠️ WARNING: VM should be set up with no GCP service account
|
||||
- external contributors could contribute malicious PRs to run code on our test VM. Ensure no service accounts or other secrets exist on the VM
|
||||
- An empty GCP project should be used for extra security
|
||||
- to set up dependencies, run the following commands:
|
||||
```
|
||||
# install kubectl
|
||||
sudo apt-get install kubectl
|
||||
|
||||
# install kind
|
||||
curl -Lo ./kind "https://github.com/kubernetes-sigs/kind/releases/download/v0.7.0/kind-$(uname)-amd64" && \
|
||||
chmod +x ./kind && \
|
||||
sudo mv ./kind /usr/local/bin
|
||||
|
||||
# install skaffold
|
||||
curl -Lo skaffold https://storage.googleapis.com/skaffold/releases/latest/skaffold-linux-amd64 && \
|
||||
chmod +x skaffold && \
|
||||
sudo mv skaffold /usr/local/bin
|
||||
|
||||
# install docker
|
||||
sudo apt install apt-transport-https ca-certificates curl gnupg2 software-properties-common && \
|
||||
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add - && \
|
||||
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable" && \
|
||||
sudo apt update && \
|
||||
sudo apt install docker-ce && \
|
||||
sudo usermod -aG docker ${USER}
|
||||
|
||||
# logout and back on
|
||||
exit
|
||||
```
|
||||
- ensure GitHub Actions runs as background service:
|
||||
```
|
||||
sudo ∼/actions-runner/svc.sh install
|
||||
sudo ∼/actions-runner/svc.sh start
|
||||
```
|
||||
|
||||
|
||||
---
|
||||
## Workflows
|
||||
|
||||
### ci.yaml
|
||||
|
||||
#### Triggers
|
||||
- commits pushed to master
|
||||
- PRs to master
|
||||
- PRs to release/ branches
|
||||
|
||||
#### Actions
|
||||
- ensures kind cluster is running
|
||||
- builds all containers in src/
|
||||
- deploys local containers to kind
|
||||
- ensures all pods reach ready state
|
||||
- ensures HTTP request to frontend returns HTTP status 200
|
||||
- deploys manifests from /releases
|
||||
- ensures all pods reach ready state
|
||||
- ensures HTTP request to frontend returns HTTP status 200
