docker删除镜像

    1、说明

    对于docker镜像,尤其是开发应用构建的镜像,如果需要重新build镜像,而不改变原有版本号,则需要将原有dokcer镜像删除。删除命令很简单:docke rmi 镜像id。但有些场景直接删除会报如下错误。

    $ docker rmi  42e04
    Error response from daemon: conflict: unable to delete 42e04f0f9df2 (must be forced) - image is being used by stopped container 6503618ff193
    

    例如以下场景会报错:

    • 镜像运行的容器还在运行
    • 镜像生产的容器还存在(未运行)。

    2、删除方式

    (1)查看运行的容器,只能查看正在运行的容易

    $ docker ps
    CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
    
    

    (2)如果存在运行容器,则停止运行容器,使用: docker stop 容器id
    (3)如果没有,则使用docker ps -a方式查看未运行的容器。

    $ docker ps -a
    CONTAINER ID   IMAGE                       COMMAND                  CREATED          STATUS                      PORTS                               NAMES

    (4)删除容器:docker rm 容器id

    $ docker rm 6503618ff193
    6503618ff193
    

    (5)查看要删除的镜像id:docker ps

    $ docker images
    REPOSITORY           TAG          IMAGE ID       CREATED          SIZE
    goon-dance-admin     1.0          42e04f0f9df2   15 minutes ago   643MB
    redis                alpine3.17   1339d05b97a4   3 weeks ago      30.4MB
    alpine/git           latest       f404a400c0ad   8 months ago     39.5MB
    mysql/mysql-server   5.7.22       3cc9613ef3ba   4 years ago      244MB
    

    (6)删除镜像:docker rmi 镜像id

    $ docker rmi 42e04f
    Untagged: goon-dance-admin:1.0
    Deleted: sha256:42e04f0f9df2d13bb23af6cfef9d60234ad5d3a1f8f6a5a76bcef4812736af87
