Tune Docker Registry (continue)

1. Install docker registry
2. Read image from docker.io, rename and push it to own private registry.
3. Explore Registry API - read image catalog, hash and layers.
4. Connect to Docker API with Docker.Registry.DotNet

1. Install docker registry

# sudo docker run -d -p 5000:5000 --restart always --name registry registry:2
# sudo docker ps

2. Read image from docker.io, rename and push it to own private registry.

# sudo docker pull alexev275/coinbase
# sudo docker image ls -a
# sudo docker image tag alexev275/coinbase:latest localhost:5000/coinbase:latest
# sudo docker push localhost:5000/coinbase:latest

3. Explore Registry API - read image catalog, hash and layers.

# sudo curl -v http://localhost:5000/v2/_catalog
# sudo curl -v http://localhost:5000/v2/coinbase/tags/list
# sudo curl -v http://localhost:5000/v2/coinbase/manifests/latest

4. Connect to Docker API with Docker.Registry.DotNet
