Overview
"Docker Registry" in this context refers to the image published by Docker, which instantiates as a container that exposes the content of the local registry over TCP. Note that by default the Docker Registry container starts with HTTP support only, so all other Docker servers that use it must be configured to allow it as an "insecure registry", with --insecure-registry as described here.
Start
docker run -d -p 5000:5000 --restart=always --name registry registry:2
Test it with:
curl -v http://<''ip-address''>:5000/v2/
* Trying 192.168.1.10...
* TCP_NODELAY set
* Connected to 192.168.1.10 (192.168.1.10) port 5000 (#0)
> GET /v2/ HTTP/1.1
> Host: 192.168.1.10:5000
> User-Agent: curl/7.54.0
