private-docker-registry.md

Append test.hub to /etc/hosts (each docker host include registry server)

echo "192.168.3.100 test.hub" | sudo tee -a /etc/hosts

Generate self-signed certificates

openssl req   -newkey rsa:4096 -nodes -sha256 -keyout certs/test.hub.key \
-x509 -days 365 -out ./certs/test.hub.crt

Copy test.hub.crt to each docker host include registry server

sudo mkdir -p /etc/docker/certs.d/test.hub
sudo cp test.hub.crt /etc/docker/certs.d/test.hub

Run private docker registry with tcp port 433

docker run -d \
  --restart=always \
  --name registry \
  -v `pwd`/certs:/certs \
  -e REGISTRY_HTTP_ADDR=0.0.0.0:443 \
  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/test.hub.crt \
  -e REGISTRY_HTTP_TLS_KEY=/certs/test.hub.key \
  -p 443:443 \
