问题描述：

开启虚拟机，通过docker images查看容器运行情况

可以看出ActiveMQ的容器ID为

3af156432993

于是启动容器：

docker run 3af156432993

出现了如下问题：

[root@localhost etc]# docker run  3af156432993
2020-11-16 07:00:03,422 CRIT Supervisor running as root (no user in config file)

2020-11-16 07:00:05,722 INFO success: activemq entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)

光标一直在闪

光标一直依旧在闪

解決方案：

1.先CTRL+C
停止命令
2.运行 docker start 容器名称
我这里使用

docker start myactivemq

如下效果展示

启动成功！！！

问题所在：docker中run和start的区别

docker run -----》 指定的是一个镜像，利用镜像生成容器
docker start-----》指定的是一个容器，启动一个之前生成过的容器
