STDIN未连接到重启的Docker容器

If a container is stopped and started again, the data on the STDIN attached is passed to the container only during the first start. On all subsequent starts, no data is found on the STDIN.

I'm using fsouza/go-dockerclient. Any help would be appreciated on this. I found a related issue, but it does not lead anywhere. If this behavior is intended, what are the workarounds, if any? I need to have two phases of the container, with different STDIN data each time.
