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
