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

(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

(6)删除镜像:docker rmi 镜像id
$ docker rmi 42e04f
