Docker容器无法启动

Question

我正在尝试this docker example。但似乎我无法启动我的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Impossible to attach to a stopped container, start it first

Answer 1

我忘了附在容器上，因此收到了错误。我跑了sudo docker attach aff28c5dab36，现在一切正常。

Answer 2

当您运行docker attch命令时，容器内的buildapp命令已经完成，容器会自动停止。如果在运行docker attach命令后立即运行buildapp，您将看到其输出。
