我最近开始使用 Docker,即使我删除了所有悬空的容器和图像,Docker 仍然占用了太多空间。
当尝试运行时sudo docker system prune --all -f
它显示"container prune" requires API version 1.25, but the Docker daemon API version is 1.24
但显然我的 Docker 是版本 1.44 当我运行时sudo docker version
。
当我运行时,每个类别都是零docker system df
。
我多次使用 Docker 来生成 Python 容器并安装 Flask 之类的库,它也可以访问 docker.sock 来生成新容器。
这是否占用了所有空间?如果是这样,如何收回空间?
sudo docker info

答案1
你的docker info
命令显示了一些“有趣”的东西(读作:错误)。它说:
Client: Docker Engine - Community
Version: 25.0.0
...
Path: /usr/lib/docker/cli-plugins/docker-compose
但随后它又说:
Server:
Containers: 0
Running: 0
Paused: 0
Stopped: 0
Images: 0
Server Version: 20.10.24
...
Docker Root Dir: /var/snap/docker/common/var-lib-docker
巧合的是,客户端版本与 Docker 存储库中的最新版本相匹配,但服务器版本与snap
Docker 的最新稳定版本相匹配。
结合给定的路径(一个有/usr/lib
,另一个有/var/snap
),我相信您已经将 Docker 安装为来自 Docker 存储库的snap
包和普通包。.deb
我的建议是删除该snap
软件包,然后重新安装 Docker 以确保一切正常。
sudo snap remove docker
sudo apt-get install --reinstall docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
现在我相信 Docker 只需最新版本就能够正常工作。
还看到这个问题,有点类似。
答案2
替代原因:用户不属于docker
该组。
并docker system prune
没有明确说明,而是给出模棱两可的"container prune" requires API version 1.25, but the Docker daemon API version is 1.24
错误
添加用户至docker
组或使用sudo
。
