1. Docker Registry

1.1. Run

$ docker network create ecosystem
$ mkdir -p /home/registry
$ chmod 777 /home/registry

$ docker run \
    --detach \
    --name registry \
    --restart always \
    --net ecosystem \
    --publish 5000:5000 \
    --volume /home/registry:/var/lib/registry \
    registry:2
$ docker pull alpine
$ docker tag alpine localhost:5000/alpine
$ docker push localhost:5000/alpine

1.3. UI

$ docker run -p 5080:8080 -e REG1=http://localhost:5000/v2/ --name registry-ui atcol/docker-registry-ui

1.4. Mirror Docker Hub

Listing 24. On Docker Registry container /etc/docker/registry/config.yml
proxy:
  remoteurl: https://registry-1.docker.io
  username: [username]
  password: [password]
Listing 25. On your machine with Docker Daemon /etc/docker/daemon.json
{
  "registry-mirrors": ["https://<my-docker-mirror-host>"]
}

1.5. Auth

$ mkdir -p /home/registry/data
$ mkdir -p /home/registry/conf
$ mkdir -p /home/registry/auth
$ mkdir -p /home/registry/certs

$ docker run --entrypoint htpasswd registry:2 -Bbn myusername mypassword > /home/registry/auth/htpasswd
$ docker container stop registry
$ docker run \
    --detach \
    --name registry \
    --restart=always \
    --net ecosystem \
    --publish 5000:5000 \
    --volume /home/registry/auth:/auth \
    --volume /home/registry/certs:/certs \
    --env REGISTRY_AUTH=htpasswd \
    --env REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm \
    --env REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
    --env REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
    --env REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
    registry:2
$ docker login myregistrydomain.com:5000
