Docker documentation: https://docs.docker.com/registry/deploying/#run-a-local-registry

Note: For demo and training this type of registry is fine, TLS must be used for production

Create a registry.

$ docker run -d -p 5000:5000 --restart=always --name registry registry:2

Tag an existing image.

$ docker tag my-nginx localhost:5000/myimages/my-nginx

Push an image to the registry.

$ docker push localhost:5000/myimages/my-nginx                          
The push refers to repository [localhost:5000/myimages/my-nginx]
