Setting up a private Docker registry
It is pretty easy to run your own private Docker registry - of course there's a Docker image for it!
In the following steps I'm assuming the volume you'll be mounting to your registry is located at
Firstly create a username/password combination that you'll use when you push and pull images.
htpasswd -c -B /volumes/registry/htpasswd YOUR_USERNAME
You then want to create the file
/volumes/registry/config.yml as below. Enter your own email address to use with Let's Encrypt.
version: 0.1 log: fields: service: registry storage: cache: blobdescriptor: inmemory filesystem: rootdirectory: /var/lib/registry http: addr: :443 headers: X-Content-Type-Options: [nosniff] tls: letsencrypt: cachefile: /etc/docker/letsencrypt-cache-file email: firstname.lastname@example.org auth: htpasswd: realm: basic-realm path: /etc/docker/registry/htpasswd health: storagedriver: enabled: true interval: 10s threshold: 3
You're now ready to run the image, mounting the files we created above and listening on the required ports.
docker run -d -p 5000:5000 -p 443:443 --restart always --name registry -v /volumes/registry/config.yml:/etc/docker/registry/config.yml -v /volumes/registry/htpasswd:/etc/docker/registry/htpasswd registry:2
Configure any DNS records you need to point to this machine. The examples below use
example.com for our domain.
Using the registry from your local machine
Login (only needs to be run once):
docker login example.com
Build and tag the Docker image:
docker build -t example.com/YOUR_REPO_NAME .
docker push example.com/YOUR_REPO_NAME
