-
列出运行的容器 docker ps
-
删除运行的容器 docker rm -f "容器名称"
-
进入容器
- docker exec -it "容器名称" /bin/bash
- sudo nsenter --mount --uts --ipc --net --pid --target 22177
其中22177为pid - docker attach "容器名称"
-
通过pid查看运行的容器 docker ps -q | xargs docker inspect --format '{{.State.Pid}}, {{.Name}}' | grep "22177" //其中22177为pid
-
通过端口查看被谁使用 docker inspect $(docker ps -aq) | grep -C 30 '3306'
-
从容器中复制文件 docker cp order-app:/root/data/sqlite/monitor/center.db /storage
-
容器删除网络桥接还在 docker network disconnect -f host order-app
-
在容器中使用jdk工具(jmap、jinfo等) -> docker run --cap-add=SYS_PTRACE --name order-app ……

创建网络桥接
docker network create -d bridge mysql-net使用例子
docker rm -f mysql-net1
docker run --name mysql-net1 --network mysql-net -e MYSQL_ROOT_PASSWORD=mysql -d mysql:5.6
docker rm -f mysql-net2
docker run --name mysql-net2 --network mysql-net -e MYSQL_ROOT_PASSWORD=mysql -d mysql:5.6
进入容器
> docker exec -it mysql-net1 /bin/bash
> apt-get update
> apt-get install iputils-ping
测试
> ping mysql-net2
