修改docker默认的网段,与阿里云内网网段冲突

修改docker默认的网段,因为与阿里云内网网段冲突

1、编辑/etc/docker/daemon.json（若不存在新建即可）

{
    "bip": "178.90.0.1/24"
}
{
    "default-address-pools" : [
       {
            "base" : "18.0.0.0/16",
            "size" : 24
       }
    ]
}

2、查询docker占用网段，并删除，

docker network ls

结果里面有一些是默认

NETWORK ID     NAME                   DRIVER    SCOPE
2ce7728ad567   appsmith_default       bridge    local
04f06f2b5b35   bridge                 bridge    local
32c8ad4d94c9   cashadminpet_default   bridge    local
5886fec0cf1d   host                   host      local
e30f12ebc019   none                   null      local
155dad08d3cc   plausible_default      bridge    local
ef977cfa2d6b   umami_default          bridge    local
96e46ad7c29a   wikijs_default         bridge    local

查询docker占用网段，

route -n

结果

删除网段,一个个的删除。

docker network rm 2ce7728ad567

3.重启服务

systemctl daemon-reload
systemctl restart docker
