docker - 如何重新启动已停止的docker/whalesay容器？

Question

如Mac的Docker入门文档所述。
docker run docker/whalesay cowsay boo
每次运行此命令时，都会创建，运行和停止一个新容器。

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                         PORTS                         NAMES


0d96e4bd9c14        docker/whalesay     "cowsay boo boo"         11 days ago         Exited (0) 5 minutes ago                                     high_archimedes
3a079559382e        docker/whalesay     "cowsay boo"             11 days ago         Exited (0) 26 minutes ago                                    boring_ritchie

我怎么不能再创建一个新的docker / whalesay容器，而是重新启动现有的已停止的docker / whalesay容器并得到与以下相同的结果
docker run docker/whalesay cowsay boo
？

我试过了

docker start 0d96e4bd9c14

结果只显示

0d96e4bd9c14

没有鲸鱼所显示的鲸鱼图像。

谢谢!

根据里科的答案

“容器第二次启动，但区别在于您没有将stdout视为默认的start”

docker start -a 0d96e4bd9c14

添加-a，那么我可以看到标准输出结果。

Answer 1

容器第二次启动，但不同之处在于您没有将sttout视为start的默认值

例如:

$ docker run docker/whalesay cowsay boo

$ sudo docker ps

$ sudo docker start 3230d1589aed
3230d1589aed

现在检查显示 STATUS的 Exited (0) 2 seconds ago:

$ sudo docker ps -a
CONTAINER ID        IMAGE                    COMMAND             CREATED             STATUS                     PORTS               NAMES
3230d1589aed        docker/whalesay:latest   "cowsay boo"        46 seconds ago      Exited (0) 2 seconds ago                       evil_curie          

您可以使用 docker logs查看输出:

$ sudo docker logs 3230d1589aed
