Docker Registry Multi-Configuration Testing

This compose configuration is intended to setup a testing environment for Docker using multiple registry configurations. These configurations include different combinations of a v1 and v2 registry as well as TLS configurations.

Limitations

Currently this setup is configured to use localhost as the hostname which limits the ease of testing within Docker since localhost is always treated as an insecure registry. To treat localhost as secure the Docker code must be modified. Without localhost as secure, the test cases will not distinguish between a TLS configuration with a CA and self-signed.

Install Docker Compose

1. Open a new terminal on the host with your distribution source.

2. Get the docker-compose binary.

    $ sudo wget https://github.com/docker/compose/releases/download/1.1.0/docker-compose-`uname  -s`-`uname -m` -O /usr/local/bin/docker-compose
   

   This command installs the binary in the /usr/local/bin directory.

3. Add executable permissions to the binary.

    $  sudo chmod +x /usr/local/bin/docker-compose
   

Usage

Start compose setup

docker-compose up

Install Certificates

The certificates must be installed in /etc/docker/cert.d in order to use TLS client auth and use the CA certificate.

sudo sh ./install_certs.sh

Test with Docker

Tag an image as with any other private registry. Attempt to push the image.

docker pull hello-world
docker tag hello-world localhost:5440/hello-world
docker push localhost:5440/hello-world

docker tag hello-world localhost:5441/hello-world
docker push localhost:5441/hello-world
# Perform login using user `testuser` and password `passpassword`
