Issue/Introduction

Upgrading Antrea from 1.13 to 1.15 or Openshift Antrea 1.8 to 1.9 has a different image path that needs to be followed and adjusted. This will help guide you through those changes to successfully upgrade your cluster.

Environment

Antrea 1.13

Openshift Antrea 1.8

Resolution

1.  Prepare the manifests and image (antrea-operator/antrea-agent/antrea-interworking) with the new version.
   
   
2.  Update the role with the command oc apply -f role.yaml.
   
   
3.  Upgrade antrea-operator by replacing the old image with the new image.
   1. Edit the deployment with the command oc -n antrea-operator edit deploy antrea-operator. Make sure that the antrea-operator pod is running.

Example of old antrea-operator pod terminating and the new one running.

oc get pods -n antrea-operator NAME                               READY   STATUS        RESTARTS      AGE antrea-operator-644f4f8bdb-q7lm8   1/1     Terminating   8 (31m ago)   3d22h antrea-operator-7d895765f6-kmf79   1/1     Running       0             27s oc get pods -n antrea-operator NAME                               READY   STATUS    RESTARTS   AGE antrea-operator-7d895765f6-kmf79   1/1     Running   0          47s

Next you will upgrade Antrea

1. First, we need to apply the new CRD definition.
   
   oc apply -f operator.antrea.vmware.com_antreainstalls_crd.yaml 

OUTPUT:
   
   customresourcedefinition.apiextensions.k8s.io/antreainstalls.operator.antrea.vmware.com configured
   
   
2. Edit operator.antrea.vmware.com_v1_antreainstall_cr.yaml with the two new fields. 
   
   antreaAgentImage: <Change this to Image Path>
   antreaControllerImage: <Change this to Image Path>
   
   
3. (OPTIONAL) If antrea-interworking is enabled, update interworkingImage with the new antrea-interworking image.

Once the yaml has been edited, you may start the upgrade. 

oc apply -f  operator.antrea.vmware.com_v1_antreainstall_cr.yaml

OUTPUT:

antreainstall.operator.antrea.vmware.com/antrea-install configured
