Openshift 3.11版本

Openshift SDN网络插件ovs-subnet 与 ovs-multitenant切换

1. 更改节点上的networkPluginName的配置

• master节点：/etc/origin/master/master-config.yaml
• node节点：/etc/origin/node/node-config.yaml
• 将networkPluginName中的redhat/openshift-ovs-subnet换成redhat/openshift-ovs-multitenant,或者反过来。

$ ansible all -m shell -a 'sed -i "s/openshift-ovs-subnet/openshift-ovs-multitenant/g" /etc/origin/node/node-config.yaml'
$ ansible masters  -m shell -a 'sed -i "s/openshift-ovs-subnet/openshift-ovs-multitenant/g" /etc/origin/master/master-config.yaml'

2. 重启master节点上的origin-master-api和origin-master-controllers服务

$ ansible masters -m shell -a 'master-restart api' -f 1
$ ansible masters -m shell -a 'master-restart controllers' -f 1

3. 停止节点上的origin-node服务

$ ansible all -m service -a 'name=origin-node state=stopped'

4. 在所有节点上重启Openshift SDN服务

$ oc delete pod --all -n openshift-sdn

5. 在所有节点上重启origin-node服务

$ ansible all -m service -a 'name=origin-node state=started'

6. 如果是从openshift sdn插件切换到第三方插件，需要清空将openshit sdn的特性

$ oc delete clusternetwork --all
$ oc delete hostsubnets --all
$ oc delete netnamespaces --all

7. 检查VNIDs

$ oc get netnamespace

Openshift SDN网络插件ovs-multitenant 切换到 ovs-networkpolicy

1. 下载切换脚本并更改执行权限

$ curl -O https://raw.githubusercontent.com/openshift/origin/master/contrib/migration/migrate-network-policy.sh
$ chmod a+x migrate-network-policy.sh

2. 执行脚本，openshift使用cluster-admin权限的用户

$ ./migrate-network-policy.sh
