Patch an image

Oracle releases Oracle SOA Suite images regularly with the latest bundle and recommended interim patches in My Oracle Support (MOS). However, if you need to create images with new bundle and interim patches, you can build these images using the WebLogic Image Tool.

If you have access to the Oracle SOA Suite patches, you can patch an existing Oracle SOA Suite image with a bundle patch and interim patches. Oracle recommends that you use the WebLogic Image Tool to patch the Oracle SOA Suite image.

Recommendations:

  • Use the WebLogic Image Tool create feature for patching the Oracle SOA Suite Docker image with a bundle patch and multiple interim patches. This is the recommended approach because it optimizes the size of the image.
  • Use the WebLogic Image Tool update feature for patching the Oracle SOA Suite Docker image with a single interim patch. Note that the patched image size may increase considerably due to additional image layers introduced by the patch application tool.

Apply the patched Oracle SOA Suite image

To update an Oracle SOA Suite domain with a patched image, first make sure the patched image is pulled or created and available on the nodes in your Kubernetes cluster. Once the patched image is available, you can follow these steps to update the Oracle SOA Suite domain with a patched image:

Stop all servers

Note: The following steps are applicable only for non-Zero Downtime Patching. For Zero Downtime Patching, go to Address post-installation requirements.

Before applying the patch, stop all servers in the domain:

  1. In the domain.yaml configuration file, update the spec.serverStartPolicy field value to NEVER.

  2. Shut down the domain (stop all servers) by applying the updated domain.yaml file:

    $ kubectl apply -f domain.yaml

Update user permissions of the domain PV storage

The Oracle SOA Suite image for release 22.4.2 has an oracle user with UID 1000, with the default group set to root. Before applying the patched image, update the user permissions of the domain persistent volume (PV) to set the group to root:

$ sudo chown -R 1000:0 /scratch/k8s_dir/SOA

Address post-installation requirements

If the patches in the patched Oracle SOA Suite image have any post-installation steps, follow these steps:

Create a Kubernetes pod with domain home access

  1. Get domain home persistence volume claim details for the Oracle SOA Suite domain.

    For example, to list the persistent volume claim details in the namespace soans:

    $ kubectl get pvc -n soans

    Sample output showing the persistent volume claim is soainfra-domain-pvc:

    NAME                  STATUS   VOLUME               CAPACITY   ACCESS MODES   STORAGECLASS                    AGE
soainfra-domain-pvc   Bound    soainfra-domain-pv   10Gi       RWX            soainfra-domain-storage-class   xxd

  2. Create a YAML soapostinstall.yaml using the domain home persistence volume claim.

    For example, using soainfra-domain-pvc per the sample output:

    Note: Replace soasuite:12.2.1.4-30761841 with the patched image in the following sample YAML:

    apiVersion: v1
kind: Pod
metadata:
  labels:
     run: soapostinstall
  name: soapostinstall
  namespace: soans
spec:
 containers:
 - image: soasuite:12.2.1.4-30761841
   name: soapostinstall
   command: ["/bin/bash", "-c", "sleep infinity"]
   imagePullPolicy: IfNotPresent
   volumeMounts:
   - name: soainfra-domain-storage-volume
     mountPath: /u01/oracle/user_projects
 volumes:
 - name: soainfra-domain-storage-volume
   persistentVolumeClaim:
    claimName: soainfra-domain-pvc

  3. Apply the YAML to create the Kubernetes pod:

    $ kubectl apply -f soapostinstall.yaml
Perform post-installation steps

If you need to perform any post-installation steps on the domain home:

  1. Start a bash shell in the soapostinstall pod:

    $ kubectl exec -it -n soans soapostinstall -- bash

    This opens a bash shell in the running soapostinstall pod:

    [oracle@soapostinstall oracle]$

  2. Use the bash shell of the soapostinstall pod and perform the required steps on the domain home.

  3. After successful completion of the post-installation steps, you can delete the soapostinstall pod:

    $ kubectl delete -f  soapostinstall.yaml

Apply the patched image

After completing the required SOA schema upgrade and post-installation steps, start up the domain:

  1. In the domain.yaml configuration file, update the image field value with the patched image:
    For example:

      image: soasuite:12.2.1.4-30761841

  2. In case of non-Zero Downtime Patching, update the spec.serverStartPolicy field value to IF_NEEDED in domain.yaml.

  3. Apply the updated domain.yaml configuration file to start up the domain.

    $ kubectl apply -f domain.yaml

    Note: In case of non-Zero Downtime Patching, the complete domain startup happens, as the servers in the domain were stopped earlier. For Zero Downtime Patching, the servers in the domain are rolling restarted.

  4. Verify the domain is updated with the patched image:

    $ kubectl describe domain <domainUID> -n <domain-namespace>|grep "Image:"

    Sample output:

    $ kubectl describe domain soainfra -n soans |grep "Image:"
Image:                          soasuite:12.2.1.4-30761841
