我试图运行this docker example.但似乎我不能启动码头容器.

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

当我尝试运行
sudo docker附加aff28c5dab36,我看到不可能附加到一个停止的容器,先启动它
