本地镜像管理

docker images: 列出本地镜像;
docker rmi:删除本地镜像;
docker tag:标记本地镜像;
docker build:使用DockerFile创建镜像;
docker history:查看指定镜像的创建历史;
docker save:将指定镜像保存成tar归档文件;
docker load:导入使用docker save命令导出的镜像;
docker import:从归档文件中创建镜像;
docker commit:从容器修改中创建新的镜像;

列出本地镜像

docker images [OPTIONS] [REPOSITORY[:TAG]]

Options:
  -a, --all             Show all images (default hides intermediate images(默认隐藏中间镜像层))
      --digests         Show digests(显示摘要信息)
  -f, --filter filter   Filter output based on conditions provided(显示满足条件的镜像)
      --format string   Pretty-print images using a Go template
      --help            Print usage
      --no-trunc        Don't truncate output(显示完整的镜像信息)
  -q, --quiet           Only show numeric IDs

删除本地镜像

语法如下:

docker rmi [OPTIONS] IMAGE [IMAGE...]

Options:
  -f, --force      Force removal of the image(强制删除镜像)
      --no-prune   Do not delete untagged parents(不移除该镜像的过程镜像,默认移除)

例如:

# 删除所有镜像
docker rmi $(docker images -q) 

# 批量删除无用镜像
docker rmi $(docker images -f dangling=true)

标记本地镜像

docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]
