Docker 运行不起作用，即使它可以拉取镜像并且 docker 正在运行

Question

这是我的电脑配置。

pegasus@pegasus:~$ uname -a
Linux pegasus 6.8.0-36-generic #36-Ubuntu SMP PREEMPT_DYNAMIC Mon Jun 10 10:49:14 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

我已经按照这里提到的方式设置了我的docker。 来自守护进程的错误响应：获取“https://registry-1.docker.io/v2/”：proxyconnect tcp：拨打tcp：在8.8.8.8:53上查找proxy.example.com：没有这样的主机

但是目前在执行 sudo apt update 之后，我面临着即使在拉取之后也无法运行大多数 docker 镜像的问题。

我该如何修复它？

Answer 1

docker run ubuntu:22.04

不会做任何事情。它启动一个 shell，发现没有 TTY 连接并终止。所以这正如预期的那样。

docker run -it ubuntu:22.04

然后你应该进入容器中的外壳。

docker ps

不显示任何内容的原因是它只显示正在运行的容器，而您没有任何容器。我你愿意

docker ps -a

它还会显示已终止的容器，您应该会看到 Ubuntu 容器处于退出状态。
