[常见错误]Bind for 0.0.0.0:8889 failed: port is already allocated.

启动雷达驱动或者microros驱动时提示，端口占用问题

docker: Error response from daemon: driver failed programming external connectivity on endpoint infallible_proskuriakova (debfb01090b05c2f1f5d12202f1bb2fca86aa480f38e4c946dec870df425930f): Bind for 0.0.0.0:8889 failed: port is already allocated.

原因是端口被占用，最大可能是重复或者多次启动了该镜像

通过docker ps -a | grep 8889

可以看到已经有一个启动了的

docker ps -a | grep 8889
3f7c920c8b44   fishros2/fishbot_laser                  "/bin/bash /scripts/…"   14 minutes ago   Up 14 minutes               0.0.0.0:8889->8888/tcp, :::8889->8888/tcp                       xenodochial_jepsen

接着我们尝试将这个容器关掉

docker stop xenodochial_jepsen

再次启动，就可以了
