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

Usage: docker build [OPTIONS] PATH | URL | -

Build a new image from the source code at PATH

  -f, --file=""        Name of the Dockerfile(Default is 'Dockerfile' at context root)
  --force-rm=false     Always remove intermediate containers, even after unsuccessful builds
  --help=false         Print usage

  --rm=true            Remove intermediate containers after a successful build
  -t, --tag=""         Repository name (and optionally a tag) to be applied to the resulting image in case of success
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
