Setting Up A Local Docker Registry
The goal of this is to have a docker registry setup on my local network.
I used the Testing an insecure registry for instructions on how to set it up.
$ mkdir -p certs && openssl req \ -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key \ -x509 -days 365 -out certs/domain.crt
After that, I copeied the domain.crt file to the /usr/local/share/ca-certificates directory as hostname.crt, then ran update-ca-certificates to make it trusted by Ubuntu.
Below is a docker-compose entry for the host:
registry: environment: REGISTRY_HTTP_TLS_CERTIFICATE: '/certs/domain.crt' REGISTRY_HTTP_TLS_KEY: '/certs/domain.key' hostname: registry image: registry:2 ports: - '5000:5000' restart: unless-stopped volumes: - /etc/timezone:/etc/timezone:ro - /config/registry:/certs:ro - /data/registry:/var/lib/registry
Now I can docker build -t hostname:5000/image . and then docker push hostname:5000/image to push the image to the remote registry.
