networking之如何更改 docker swarm 入口网络的 IP 地址范围

我使用 docker swarm 1.13.1，当我初始化 docker swarm 或加入 docker swarm 时，它有时会在“172.19.0.0/16”子网中创建一个 docker_gwbridge 网络。

但是我的计算机子网在相同的范围内，所以当它初始化这个网络时，docker swarm 主机变得无法从我的计算机访问。

所以我的问题是:如何更改现有 docker 网络的子网。

> docker network ls 
NETWORK ID          NAME                DRIVER              SCOPE 
ac1100164960        bridge              bridge              local 
3838ae360f35        docker_gwbridge     bridge              local 
f9a77266aa15        host                host                local 
rgqnm19zbasv        ingress             overlay             swarm 
04c1c6b3ade7        none                null                local 

> docker network inspect 3838ae360f35

        }, 
        "Labels": {} 
    } 
] 

请您参考如下方法:

您可以创建 docker_gwbridge在初始化群之前，如 explained here .
例如:

docker network rm docker_gwbridge 
docker network create --subnet=172.20.0.1/16 -o com.docker.network.bridge.enable_icc=false -o com.docker.network.bridge.name=docker_gwbridge docker_gwbridge
