docker容器和宿主机网络不通

防火墙未开启，检查网络配置无异常

解决：

[root@localhost ~]# vim /etc/sysctl.confnet.bridge.beidge-nf-call-iptables = 1
net.bridge.beidge-nf-call-ip6tables = 1[root@localhost ~]# sysctl -p
[root@localhost ~]# systemctl restart docker

如果网络还是不通，重建docker0网卡

[root@localhost ~]# systemctl stop docker
[root@localhost ~]# ip link set dev docker0 down
[root@localhost ~]# brctl delbr docker0
[root@localhost ~]# brctl addbr docker0
[root@localhost ~]# ip addr add 172.17.0.1/16 dev docker0
[root@localhost ~]# ip link set dev docker0 up
[root@localhost ~]# systemc start docker
