删除 Docker 中的本地镜像
本文将介绍在 Docker 中删除本地镜像的方法。
删除 Docker 中未使用和悬空的本地映像
假设除了有未标记的 docker 镜像之外，你还有未使用的镜像和一些你还想删除的容器。在这种情况下，请选择下面显示的命令。
$ docker system prune -a
此命令将提示警告，让你知道如果你选择是，此命令将：
- 删除所有停止的容器；
- 删除至少一个容器未使用的所有网络；
- 删除所有没有至少一个与之关联的容器的镜像；
- 删除所有缓存。
但是，如果此命令不符合你需要完成的内容，并且你只想删除：
- 未标记或悬空的镜像；
- 停止的容器；
- 悬空缓存；
- 网络未被至少一个容器使用。
在这种情况下，使用 prune 命令而不包括 -a 标签，如下所示。
$ docker system prune
删除 Docker 中的特定本地映像
我们可能还想从本地系统中删除特定镜像，并保持所有其他文件不变。
在这种情况下，我们需要一个我们想要删除的特定镜像的镜像 ID。我们可以通过 Docker 桌面应用程序中的镜像页面访问它。
我们还可以通过运行以下命令，使用我们的终端或 Docker CLI 访问映像 ID。
isaactonyloi@DESKTOP-HV44HT6:~$ docker images -a
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest c316d5a335a5 3 weeks ago 142MB
现在我们已经获得了镜像 ID，我们可以使用 docker rmi 命令附加到镜像 ID 中删除该特定镜像，如下所示。
$ docker rmi c316d5a335a5
输出：
Untagged: nginx:latest
Untagged: nginx@sha256:2834dc507516af02784808c5f48b7cbe38b8ed5d0f4837f16e78d00deb7e7767

使用 Docker 中的过滤器删除未标记的本地镜像
我们还可以使用过滤器和通配符来识别悬空镜像，即不与任何容器关联的镜像。我们可以使用过滤标签 -f找到满足条件 dangling=true 的图片。
下面的命令应该列出与任何容器无关的所有镜像。但是，请注意，如果你的系统中没有未标记的镜像，则该命令将仅返回标头。
$ docker images -a -f dangling=true
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest c316d5a335a5 3 weeks ago 142MB
删除 Docker 中的所有本地镜像
当与 -a 标签一起使用时，-q 标签允许我们检索并列出本地系统中的所有镜像 ID。
$ docker images -a -q
54c9d81cbb44
c316d5a335a5
使用此命令，我们可以列出 docker rmi 下的所有镜像，以从我们的系统中删除所有镜像。这是我们如何嵌套该命令以消除所有镜像。
$ docker rmi $(docker images -a -q)
输出：
Untagged: ubuntu:latest
Untagged: ubuntu@sha256:669e010b58baf5beb2836b253c1fd5768333f0d1dbcb834f7c07a4dc93f474be
