最佳实践

1. Create a password file with one entry for the user testuser, with password testpassword:

   $ mkdir auth
   $ docker run \
     --entrypoint htpasswd \
     registry:2 -Bbn testuser testpassword > auth/htpasswd
   
   

2. Stop the registry.

   $ docker container stop registry
   
   

3. Start the registry with basic authentication.

   $ docker run -d \
     -p 5000:5000 \
     --restart=always \
     --name registry \
     -v "$(pwd)"/auth:/auth \
     -e "REGISTRY_AUTH=htpasswd" \
     -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
     -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
     -v "$(pwd)"/certs:/certs \
     -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
     -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
     registry:2
   
   

4. Try to pull an image from the registry, or push an image to the registry. These commands fail.

5. Log in to the registry.

   $ docker login myregistrydomain.com:5000
   
   

   Provide the username and password from the first step.

   Test that you can now pull an image from the registry or push an image to the registry.

Tag the image so that it points to your registry

docker image tag ubuntu localhost:5000/myfirstimage

Push it

docker push localhost:5000/myfirstimage

Pull it back

docker pull localhost:5000/myfirstimage
