怎么关闭 docker buildx?

Question

之前启用 docker buildx 之后，我的 docker build 也变成 docker build 了！！！

可恶，怎么关闭 docker buildx？

╰─➤  docker build  
ERROR: "docker buildx build" requires exactly 1 argument.
See 'docker buildx build --help'.

Usage:  docker buildx build [OPTIONS] PATH | URL | -

执行 docker buildx uninstall 没有效果

╰─➤  docker buildx uninstall                                                                                                                                                                                                                                                                                  130 ↵

~/.docker/config.json 里面也没有别名

╰─➤  cat ~/.docker/config.json                                                                       1 ↵

                }
        }
}%

https://github.com/docker/buildx#set-buildx-as-the-default-builder

To remove this alias, run docker buildx uninstall.

别名的实质就是往 ~/.docker/config.json 文件（如果你没改过默认配置文件地址的话）里写了个 aliases。你也可以试着手动编辑一下这个配置文件，把别名删掉，然后重启 docker 服务。

docker buildx prune

上面的命令可以彻底移除 docker buildx

root@lsr-refresh:~# docker buildx prune

Answer 4

我也被这个折腾了好久。

~/.docker/config.json 里清理aliases，就可以了

    "aliases": {
            "builder": "buildx"
    }

如果异常，检查一下Dockerfile，基础镜像与当前架构是否一致。
