Openstack instance deploy calico network problem
网络问题如下图所示：
同样的环境，在vmware workstation环境里面不存在问题。怀疑是安全组导致。
先查看下其中一个instancet port信息：
[root@openstack01 ~]# neutron port-list |grep 192.168.184.18
| febc2ed8-73e8-47dc-81ac-1120906f8dda | | 570d912f61a94e83a18f1fa455815cbb | fa:16:3e:90:6e:20 | {"subnet_id": "924f1705-c49d-4e2c-8e8c-b184521d9cc6", "ip_address": "192.168.184.18"} |
查看关于tap设备的iptables信息：
[root@openstack01 ~]# iptables --line-numbers -nvL | grep tapfebc2ed8-73
35 60849 160M neutron-openvswi-sg-chain all -- * * 0.0.0.0/0 0.0.0.0/0 PHYSDEV match --physdev-out tapfebc2ed8-73 --physdev-is-bridged /* Direct traffic from the VM interface to the security group chain. /

关闭port的安全组:
[root@openstack01 ~]# opnestack port set --no-security-group febc2ed8-73e8-47dc-81ac-1120906f8dda
[root@openstack01 ~]# openstack port set --disable-port-security febc2ed8-73e8-47dc-81ac-1120906f8dda
关闭安全组后：
[root@openstack01 ~]# iptables --line-numbers -nvL | grep tapfebc2ed8-73
35 1 52 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 PHYSDEV match --physdev-out tapfebc2ed8-73 --physdev-is-bridged /* Accept all packets when port security is disabled. /
36 1 64 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 PHYSDEV match --physdev-in tapfebc2ed8-73 --physdev-is-bridged / Accept all packets when port security is disabled. /
18 0 0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 PHYSDEV match --physdev-in tapfebc2ed8-73 --physdev-is-bridged / Accept all packets when port security is disabled. */
此刻，calico网络中的两个容器可以相互通信了。
