Docker 日本語環境構築まとめ 2 ではコンテナの作成を行った

今回はDocker HUBにpush して、別の環境にpullして問題なく動作するかを確認

1 docker hub　アカウントを作成
2 docker hub へpush
3 docker hubからpull

Docker hub アカウントを作成

さくっと作成してPUBLICリポジトリを作成

Docker HUB へPUSH

PUSH事前準備


== act_chkが今回のpush対象

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
act_chk             1.0                 d2b0a3cbbbac        About a minute ago   588MB

== imageにtagをつける(これはそういうものらしい)

$ docker tag 6aeea82f960e testrepo/act_chk


== testrepo/act_chkが生成されたことを確認

$ docker images
REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
