====== 22 Docker Private registry ======

Docker用のローカルRepogitoryを用意してみる。


===== Port:4000でローカルregistry用意 =====

<code>
docker run -d \
 --name registry \
 --restart=always \
 -p 4000:5000 \
 -v registry:/var/lib/registry \
 registry:2
</code>


===== image作成 =====

[[06_virtualization:05_container:11_docker_create_image]]


==== insecure(HTTP)で通信できるようにしておく ====

<code>
# cat << __EOM__ | tee /etc/docker/daemon.json
{ "insecure-registries":["192.168.10.10:4000"] }
__EOM__

systemctl restart docker
</code>
===== image push =====

タグを付けて
  docker tag my-centos7:latest 192.168.10.10:4000/my-centos7:latest

Push
  docker push 192.168.10.10:4000/my-centos7:latest

確認
<code>
$ curl -sk http://192.168.10.10:4000/v2/_catalog | jq
{
  "repositories": [
    "my-centos7"
  ]
}
</code>

他のノードからPullしてみる
  docker pull 192.168.10.10:4000/my-centos7

===== image一覧確認 =====

<code>
$ curl -sk http://192.168.10.10:4000/v2/_catalog | jq

    "kolla/cinder-api",

===== imageのタグ一覧 =====

<code>
$ curl -sk http://192.168.10.201:4000/v2/kolla/haproxy/tags/list | jq
{
  "name": "kolla/haproxy",
  "tags": [
    "xena",
    "yoga"
  ]
}
</code>


===== 実ファイルのpath =====

docker volumesの下にregistryというフォルダができてるので、それをバックアップしておけば良いと思います。

<code>
