Description of problem: The ip address that flannel get in x390s system is not the same as we set it in etcd. Version-Release number of selected component (if applicable): [root@ibm-z-23 ~]# rpm -qa|grep flannel flannel-0.7.1-2.el7.s390x How reproducible: 100% Steps to Reproduce: 1. set up a etcd server and set flannel config in it 2. start flanneld service 3. use systemctl status and ip addr to check the ip address it get Actual results: the ip is different with the one we set Expected results: the ip should be the same as we set Additional info: I tried to change the atomic.io/network/config to several value: 10.20.0.0 , 10.30.0.0 or 172.10.0.0. But the flannel always get the same ip: 10.91.0.0. Also tried to get the config from another etcd server and it changed to 10.35.0.0 but still not fit the configuration which is 10.10.0.0. flannel status info: [root@ibm-z-23 ~]# systemctl status flanneld -l ● flanneld.service - Flanneld overlay address etcd agent Loaded: loaded (/usr/lib/systemd/system/flanneld.service; disabled; vendor preset: disabled) Active: active (running) since Thu 2017-06-22 23:19:58 EDT; 5s ago Process: 64531 ExecStartPost=/usr/libexec/flannel/mk-docker-opts.sh -k DOCKER_NETWORK_OPTIONS -d /run/flannel/docker (code=exited, status=0/SUCCESS) Main PID: 64521 (flanneld) CGroup: /system.slice/flanneld.service └─64521 /usr/bin/flanneld -etcd-endpoints=http://127.0.0.1:2379 -etcd-prefix=/atomic.io/network Jun 22 23:19:58 ibm-z-23.rhts.eng.bos.redhat.com systemd[1]: Starting Flanneld overlay address etcd agent...
