Docker 根据网络名称批量断开与之相连的容器shell实现

实践环境

Centos7

Docker 20.10.5

问题描述

使用 docker-compose down 命令关闭容器时，提示类似以下错误：

Removing network xxx_default
ERROR: network xx_default id cec096539c911cc9c2f79a6e2152c9297c4f13778a05cce3f4beb85d78c02599 has active endpoints

解决方法

查看网络信息

    }
]

SHELL实现批量断开与目标网络关联的容器：

#!bin/bash
for i in `docker network inspect -f '{{range .Containers}}{{.Name}} {{end}}' testproject_default`; 
  do 
     sudo docker network disconnect -f testproject_default $i; 
  done;
if [ $? -ne 0 ]; then
    echo "断开容器关联网络 testproject_default 失败"
    exit 1
else
    echo -e "断开容器关联网络 testproject_default 成功
"
fi

注意：

实践时发现，这样以后，有时候还是会存在上述问题问题

解决方法：重启Docker

sudo service docker restart
