建立多個docker host共用的private registry

//建立多個docker host(swarm mode)共用的private registry

1.  mkdir /certs

2.  openssl req -newkey rsa:4096 -nodes -sha256 -keyout /certs/dockerrepo.key -x509 -days 365 -out /certs/dockerrepo.crt -subj /CN=docker1

3.  mkdir /home/registry

4.  docker run -d -p 9527:5000 --restart=always --name myregistry \
-v /certs:/certs -v /home/registry:/var/lib/registry \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/dockerrepo.crt \
-e REGISTRY_HTTP_TLS_KEY=/certs/dockerrepo.key \
registry

5.  mkdir -p /etc/docker/certs.d/docker1:9527/

6.  cp dockerrepo.crt /etc/docker/certs.d/docker1\:9527/ca.crt

7.  docker tag alpine:latest docker1:9527/alpine:1

8.  docker push docker1:9527/alpine:1

※每個docker host都要做步驟5~6
docker stop myregistry && docker rm -v myregistry //停止
