harbor修改了docker默认网卡失效原因
1. 问题
修改了docker的默认网段，但是harbor启动时候又会出现docker默认的网段，故现找下原因
2. docker修改默认网段
2.1 删除原有配置
service docker stop
ip link set dev docker0 down
brctl delbr docker0
iptables -t nat -F POSTROUTING2.2 创建新的网桥
brctl addbr docker0
ip addr add 192.17.10.1/24 dev docker0
ip link set dev docker0 up2.3 配置docker文件
vi /etc/docker/daemon.json
[root@bogon ~]# cat /etc/docker/daemon.json ##追加的即可
{"registry-mirrors": ["http://224ac393.m.daocloud.io"],
"bip": "192.17.10.1/24"
}
[root@bogon ~]# systemctl restart docker3. 启动harbor
[root@ceph harbor]# docker-compose up -d

[root@ceph harbor]# ip addr

inet6 fe80::42:c0ff:fe31:3791/64 scope link可以看到又启动了docker的默认网段，由于docker-compose up创建新的网桥的时候都是使用默认的172网段的
3.1 解决
[root@ceph harbor]# cat /etc/docker/daemon.json
{
"debug" : true,
"default-address-pools" : [
{
"base" : "12.11.0.0/16",
"size" : 24
}
]
}[root@ceph harbor]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo

inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

valid_lft forever preferred_lft forever
19: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
link/ether 02:42:b5:b4:c9:0b brd ff:ff:ff:ff:ff:ff

valid_lft forever preferred_lft forever
inet6 fe80::42:e4ff:fe23:a8f5/64 scope link
valid_lft forever preferred_lft forever也可以直接修改docker-compose文件
