docker - Docker 容器未启动

Question

我正在尝试运行这个 docker 示例。然而，我似乎无法启动我的 docker 容器。

sudo docker stop aff28c5dab3f
sudo docker start aff28c5dab3f
sudo docker ps
ID                  IMAGE               COMMAND             CREATED             STATUS              PORTS

sudo docker ps -a
ID                  IMAGE                     COMMAND                CREATED             STATUS              PORTS

当我尝试跑步时 sudo docker attach aff28c5dab36，我看到了Impossible to attach to a stopped container, start it first

Answer 1

我忘记附加到容器上，因此出现错误。我跑了sudo docker attach aff28c5dab36，现在一切正常。

Answer 2

有可能当你运行docker attch命令时，buildapp容器内的命令已经执行完毕，容器自动停止。如果您docker attach在运行命令后立即运行buildapp，您将看到它的输出。
