运行 docker-compose 时权限被拒绝，即使使用 sudo

Question

我已经有一个基于 docker 的环境运行ning 几个月了，通过 docker-compose 配置并尝试添加新的 Radarr/Tdarr 容器到配置。当重新运行使用 docker-compose 命令时，它 returns 一个权限被拒绝的错误如下：

dhevans@ubuntu:/htpc-svc$ sudo docker-compose pull && docker-compose up -d
Pulling plex-server   ... done
Pulling homeassistant ... done
Pulling node-red      ... done
Pulling watchtower    ... done
Pulling radarr        ... done

在我对这些容器进行测试期间，我已经从合成文件中删除了新图像，但它仍然 returns 错误。这向我表明这与新容器无关，而是与 Docker 不再起作用的东西有关。

如果我运行 sudo docker-compose up 或 sudo docker-compose up radarr，容器启动正常并且我能够远程访问 Web 服务。在我终止命令之前，它们会按预期运行。这向我表明图像或配置没有真正的问题，但是有一些东西阻止我让我的 docker 撰写文件正确启动整个配置。

tl；博士；尝试将新容器添加到 docker-compose。总是得到错误。删除了新容器，仍然出现错误。旧网站仍然可用，新网站只能通过 docker-compose-up 运行。一切都是运行作为 sudo。请告诉我我做错了什么，或者我已经用头撞砖墙几个小时了，应该看看哪里。

Answer 1

我删除了除第一个服务之外的所有服务，重新启动了该服务。

我重新添加了服务，一个接一个，每次都启动一个新的。

我没有收到任何错误。我执行了 sudo docker-compose down，所有容器都停止了。我重新发布了 sudo docker-compose up -d，所有容器都启动了，没有任何错误。

我不知道为什么这次成功了，之前却不行...

Answer 2

您首先得到的错误似乎不是 heisenbug，但在没有 sudo 的情况下运行 docker-compose 应该可以重现（因为 Docker daemon socket 属于 root:docker).

更准确地说，错误与您执行命令的事实有关：

sudo docker-compose pull && docker-compose up -d  #(1.)

与

的语义不同

sudo /bin/bash -c "docker-compose pull && docker-compose up -d"  #(2.)

因此，命令 1. 的 docker-compose up -d 部分是运行 没有 root 权限。

因此，如果您想在不使用运行额外的 bash 过程的情况下将两者结合起来，您可以运行:

sudo docker-compose pull && sudo docker-compose up -d

顺便说一句，请注意可以从 Docker 命令中“删除”sudo 前缀，至少有两种方式：加入 docker 组（可以在个人工作站上有风险），或使用 bash 别名；参见例如.
