最近参与一些运维工作，因此做一下容器运维的常用命令笔记。

docker ps

docker ps命令参数：

• -a 显示所有容器，包括停止状态的
• --format 输出格式(ID,Names,Image,Created,Status,Ports,Command)
• --no-trunc 显示完整的输出格式（包括Command）

如下所示：

docker ps --no-trunc --format "table {{.Names}}\t{{.Image}}\t{{.Command}}"
docker ps --no-trunc --format "table {{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Command}}"
docker ps --no-trunc --format "table {{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Ports}}\t{{.Command}}"

docker inspect

docker inspect 用于查看某容器的运行状态，例如：

docker inspect Pro-MySQL8035
