This section shows you how to patch or upgrade the the OHS image used by an OHS container.
To show the version of the image the OHS container is currently running, run the following command:
$ kubectl describe pod <pod> -n <namespace> | grep Image
For example:
$ kubectl describe pod ohs-domain-d5b648bc5-qsgts -n ohsns | grep Image
The output will look similar to the following:
Image: container-registry.oracle.com/middleware/ohs_cpu:12.2.1.4-jdk8-ol8-<version>
Image ID: 9a7199ac903114793d6ad1f320010c3dbd59a39ad9bc987d926d3422a68603e7
Run the following command to update the container with the new image:
$ kubectl set image deployment/ohs-domain -n <namespace> ohs=<new_image>
For example:
$ kubectl set image deployment/ohs-domain -n ohsns ohs=container-registry.oracle.com/middleware/ohs_cpu:12.2.1.4-jdk8-ol8-<new>
The output will look similar to the following:
deployment.apps/ohs-domain image updated
This command will perform a rolling restart of the OHS container by shutting down the existing OHS container and starting a new one.
Run the following kubectl command to view the pods:
$ kubectl get pods -n <domain_namespace>
For example:
$ kubectl get pods -n ohsns
The output will look similar to the following:
NAME READY STATUS RESTARTS AGE
ohs-domain-5c9c9879d-kpt9j 0/1 ContainerCreating 0 8s
ohs-domain-d5b648bc5-qsgts 1/1 Terminating 0 17h
The existing OHS pod will move to a STATUS of Terminating and a new OHS pod will be started.
To check what is happening while the pods are in ContainerCreating status, you can run:
$ kubectl describe pod <podname> -n <namespace>
To check what is happening while the pods are in 0/1 Running status, you can run:
$ kubectl logs -f <pod> -n <namespace>
Keep running the kubectl get pods -n <namespace> command until the pod is Running and at READY 1\1:
NAME READY STATUS RESTARTS AGE
ohs-domain-5c9c9879d-kpt9j 1/1 Running 0 6m40s
To show the OHS container is running the new image, run the following command:
$ kubectl describe pod <pod> -n <namespace> | grep Image
For example:
$ kubectl describe pod ohs-domain-5c9c9879d-kpt9j -n ohsns | grep Image
The output will look similar to the following:
Image: container-registry.oracle.com/middleware/ohs_cpu:12.2.1.4-jdk8-ol8-<new>
