LeoFSのDockerイメージを使ってみた

imageをpullするだけで使える。

$ docker pull firejun/leofs

$ docker images

IPが知りたいので、

$ docker ps

$ docker inspect 9da | jq '.[].NetworkSettings.IPAddress'

leofs-admが使える

$ ./leofs-adm -h 172.17.0.1 status

バージョンはちょっとだけ古いみたいだ。SSHDも起動しているので、コンテナの中に入って設定ファイルなどを確認したりもできる。(User:leofs, Password:leofs)

ちなみにfirejunさんはLeoFSの中の人。
