docker buildしてみる

$ docker build -t uemura/mysql:1.0 .

つかねーじゃん・・・

なんでREPOSITORY/TAGがnone...orz

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
<none>              <none>              a26345e9996c        3 minutes ago       382.9 MB
centos              latest              dade6cb4530a        2 weeks ago         210.1 MB

使い方はあってるよな？

ヘルプ見てみる

$ docker build --help

仕方ないのでdocker tagで付ける

$ docker tag a26345e9996c uemura/mysql:1.0
$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
uemura/mysql        1.0                 a26345e9996c        9 minutes ago       382.9 MB
centos              latest              dade6cb4530a        2 weeks ago         210.1 MB
