2.有几个镜像需要retag

docker pull registry.example.com/openshift3/registry-console:v3.9.43 docker tag registry.example.com/openshift3/registry-console:v3.9.43 registry.example.com/openshift3/registry-console:v3.9docker push registry.example.com/openshift3/registry-console:v3.9docker pull  registry.example.com/openshift3/ose-deployer:v3.9.43docker tag registry.example.com/openshift3/ose-deployer:v3.9.43 registry.example.com/openshift3/ose-deployer:v3.9.51docker push registry.example.com/openshift3/ose-deployer:v3.9.51docker pull  registry.example.com/openshift3/ose-pod:v3.9.43docker tag registry.example.com/openshift3/ose-pod:v3.9.43 registry.example.com/openshift3/ose-pod:v3.9.51docker push registry.example.com/openshift3/ose-pod:v3.9.51

 

更新主节点

ansible-playbook -vv /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_9/upgrade_control_plane.yml | tee /tmp/upgrade_control_plane_to_3_9.log;

更新脚本不要反复执行，遇到的问题包括

 

  • 导入模板失败
TASK [openshift_examples : Import RHEL streams] *************************************************************************************************************************task path: /usr/share/ansible/openshift-ansible/roles/openshift_examples/tasks/main.yml:58FAILED - RETRYING: Import RHEL streams (3 retries left).FAILED - RETRYING: Import RHEL streams (2 retries left).FAILED - RETRYING: Import RHEL streams (1 retries left).

倒入模板失败，目前暂时没理

 

  • RETRYING: Poll for OpenShift pod deployment success
TASK [openshift_hosted : Poll for OpenShift pod deployment success] *****************************************************************************************************task path: /usr/share/ansible/openshift-ansible/roles/openshift_hosted/tasks/wait_for_pod.yml:23FAILED - RETRYING: Poll for OpenShift pod deployment success (60 retries left).FAILED - RETRYING: Poll for OpenShift pod deployment success (59 retries left).

看了一下是在docker-registry部署完后的检查，修改hosts文件，加入

openshift_hosted_manage_registry=false

 

  • 验证TSB是否运行
TASK [template_service_broker : Verify that TSB is running] ********************************************************************************FAILED - RETRYING: Verify that TSB is running (120 retries left).FAILED - RETRYING: Verify that TSB is running (119 retries left).

解决办法，修改service_broker在infra的节点上运行。（之前是node=true节点上)

template_service_broker_selector={
   "region": "infra"}

 

  • upgrade storage

脚本不能反复执行
