我有docker网络“my_network”.我想用docker network rm my_network删除这个docker网络.在此之前,我应该断开我的所有容器与此网络.我可以使用docker network inspect来获取输出

[
    {
        "Name": "my_network","Id": "aaaaaa","Scope": "some_value","Driver": "another_value","EnableIPv6": bool_value,"IPAM": {
            "Driver": "default","Options": {},"Config": [
                {
                    "Subnet": "10.0.0.0/1"
                }
            ]
        },"Internal": false,"Containers": {
            "bbb": {
                "Name": "my_container_1","EndpointID": "ENDPOITID1","MacAddress": "MacAddress1","IPv4Address": "0.0.0.0/1","IPv6Address": ""
            },"ccc": {
                "Name": "my_container_2","EndpointID": "ENDPOINTID2","MacAddress": "MacAddress2","IPv4Address": "0.0.0.0/2","IPv6Address": ""
            }
        },"Labels": {}
    }
]

如果我只有几个容器可以手动断开,但如果我有50个容器我有问题.
如何使用单个或多个命令断开此网络中的所有容器？

解决方法

docker network inspect有一个 format option.

这意味着您可以列出所有Container名称：

docker network inspect -f '{{range .Containers}}{{.Name}}{{end}}' network_name

然后通过脚本轻松读取每个名称并调用docker network disconnect.

wwerner在in the comments以下提出以下命令：

for i in ` docker network inspect -f '{{range .Containers}}{{.Name}} {{end}}' network_name`; do docker network disconnect -f network_name $i; done;

多行可读性：

for i in ` docker network inspect -f '{{range .Containers}}{{.Name}} {{end}}' network_name`;
  do 
     docker network disconnect -f network_name $i; 
  done;

添加：

Note that there is a space in the format as opposed to the answer to split the names by a space.
