Docker 删除守护进程
Docker Delete daemon
我想删除一个 Docker 守护进程;因为它在我的电脑上需要更多 space
我确实插入了代码来安装 php:5.3-apache
我使用了这个命令 docker build -t my-php-app .
我收到这个错误
Sending build context to Docker daemon 7.039GB
Error response from daemon: unexpected error reading Dockerfile: read /var/lib/docker/tmp/docker-builder079515785/dockerfile: is a directory
所以我想删除那个守护进程,因为它在我的电脑上占用很大 space;我确实尝试了 3 次安装它,每次我都遇到同样的错误,所以我现在有超过 21GB 的空间需要清理。
docker 图片给我 :
orsolin/docker-php-5.3-apache latest d8e72369c6e9 2 years ago 533MB
但是我电脑上的 space 已从 30GB 减少到 8GB
我没有看到任何 7GB 大小的东西

您不想删除该守护程序,该守护程序实际上是 运行 在您的主机上使您能够执行 运行 docker 命令的软件。
如果你想删除现有的图像、卷、容器、网络、构建缓存,你可以深入了解命令
docker system prune
小心,它会删除很多你可能仍然会用到的东西。
如果你想确定在你的主机中需要 space 的是什么,在重新清理之前,你也可以 运行
$ docker system df

Images 5 2 16.43 MB 11.63 MB (70%)

相关文档: https://docs.docker.com/engine/reference/commandline/system_df/
这可以在您的主机上回收大量 space,甚至可以为您提供它回收的 space 数量的总和:
$ docker system prune

Docker 内部 运行 在 client/server 架构上。特别是,当您 运行 docker build
时,它会在您指定的目录中创建一个 tar 文件,并通过套接字将该 tar 文件发送到 Docker 守护程序, 并在那里解压它。 (即使在完全本地的系统上也是如此。)
如果出现问题,该内容可以在 /var/lib/docker/tmp
中备份。通常你根本不应该在 /var/lib/docker
中四处寻找,但清理这个目录应该是安全的。考虑在执行此操作时停止守护进程。停止守护进程,删除所有 /var/lib/docker
,并恢复 tar 守护进程也应该有所帮助(您需要重新 docker build
and/or docker pull
图像和重新 运行 容器,这将丢失您尚未备份的命名卷中的任何内容。
7.039 GB 的构建上下文非常大。除了这样的问题,它只会导致 docker build
步骤非常慢;如果所有这些内容都被 COPY
编辑到图像中,您可能会在尝试 docker push
构建图像时遇到类似的问题。您可以尝试清理诸如日志文件或堆转储之类的东西(如果它们被遗弃);将 .git
目录或本地供应商树之类的内容添加到 .dockerignore
文件也有助于减小上下文的大小。
