docker中如何启动已存在容器
作者：x县豆瓣酱
这篇文章主要介绍了docker中如何启动已存在容器问题，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教
docker启动已存在容器
- 查看所有容器
docker ps -a
- 启动已存在容器
docker start 容器ID
docker查看容器启动命令（已运行的容器）
eg:
1 docker ps 查看正在运行的容器：
通过docker ps命令
该命令主要是为了详细展示查看运行时的command参数
docker ps -a --no-trunc | grep container_name # 通过docker --no-trunc参数来详细展示容器运行命令
通过docker inspect命令
使用docker inspect，但是docker inspect打印的是json文件，需要挑选字段查看，容器的参数信息都能从json文件中解析出来。
1，在容器外部，物理机上，可以用下面命令
docker inspect <container_name> # 可以是container_name或者container_id
eg:
[root@128 ~]# docker ps

]如上所示，这个是我这547880f43cf1 容器的详细信息
然后可以定制化输出上面的信息：显示上面内容的某一部分信息
docker inspect --format='{{.NetworkSettings.Networks.bridge.IPAddress}}' <container_name> # format是go语言的template，还有其他的用法
docker inspect --format='{{.Mounts}}' <container_name>
docker inspect --format='{{.HostConfig.Binds}}' <container_name>
docker inspect --format='{{.HostConfig.PortBindings}}' <container_name>eg: 还可以将上面的修改为别的内容，我这边关注file和port两个
[root@128 ~]# docker ps

总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
