bash - Docker 断开所有容器与 docker 网络的连接

Question

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，我应该断开所有容器与该网络的连接。我可以使用 docker network inspect 并获得类似的输出

[
    {
        "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": ""
            }
        },
        "Options": {},
        "Labels": {}
    }
]

如果我只有几个容器，可以手动断开连接，但如果我有 50 个容器，我就会遇到问题。如何使用单个或多个命令断开所有容器与该网络的连接？

docker network inspect有一个 format option .

这意味着您可以列出所有容器名称:

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

这应该很容易通过脚本读取每个名称并调用 docker network disconnect .

wwerner下面建议in the comments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;

为了便于阅读，在多行中:

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.
