背景： harbor 默认启动会随机创建 172 网段的ip地址，跟集群规划的网段冲突
Harbor 网段修改步骤
0. 原来Harbor占用的网段
# 网桥名：harbor_harbor [root@gpunode2 test]# docker network ls NETWORK ID NAME DRIVER SCOPE da8684ecc4b6 harbor_harbor bridge local # 查看路由表 [root@gpunode2 test]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.21.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br-da8684ecc4b6 # 查看网桥内部信息 docker inspect da8684ecc4b6 # 确认到Harbor占用的网段是172.21.0.0，和公司规划冲突

1、停止harbor
#停止harbor docker-compose -f /opt/harbor/docker-compose.yml down [root@gpunode2 harbor]# docker-compose -f /opt/harbor/docker-compose.yml down Stopping harbor-jobservice ... done Stopping nginx ... done Stopping harbor-core ... done Stopping harbor-db ... done Stopping registry ... done Stopping registryctl ... done Stopping redis ... done Stopping harbor-portal ... done Stopping harbor-log ... done Removing harbor-jobservice ... done Removing nginx ... done Removing harbor-core ... done Removing harbor-db ... done Removing registry ... done Removing registryctl ... done Removing redis ... done Removing harbor-portal ... done Removing harbor-log ... done Removing network harbor_harbor # 查看网桥，确认harbor_harbor是否已经删掉 docker network ls # 如果没有，使用以下命令删除网桥 # docker network remove [NETWORK ID]
2、创建Harbor新的网桥
# 创建Harbor新的网桥 docker network create --driver=bridge --subnet=172.252.0.1/16 harbor # 验证网桥信息 [root@gpunode2 harbor]# docker network ls NETWORK ID NAME DRIVER SCOPE e0a7e55534db harbor bridge local [root@gpunode2 harbor]# route -n | grep e0a7e55534db 172.252.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br-e0a7e55534db
3、修改compose配置
# 2. 修改docker-compose.yml 把最下面network false 改成true networks: harbor: external: true
4、重新启动
# 重新启动 docker-compose -f /opt/harbor/docker-compose.yml up -d --force-recreate

注意
1. 启动方式
这种方式重启后，会使用新的网桥
但是使用.prepre命令重新生成配置文件后，或者./install.sh命令重装后，还是会创建harbor_harbor随机网桥，可能会冲突
所以，在使用.prepre命令或者./install.sh命令后，记得修改docker-compose.yml 把最下面network false 改成true
2. 使用非172网段
如果使用非172网段，在步骤2：创建Harbor新的网桥，还需要修改/etc/docker/daemon.json中的bip
因为doker默认使用的也是172网段，所以harbor指定的也是172网段，就不需要额外修改docker配置，只需要修改harbor配置就好了
#修改docker 网络地址 $ cat /etc/docker/daemon.json { // 修改bip--network bridge IP "bip":"172.254.0.1/16" } # 重启docker systemctl daemon-reload systemctl start docker
