Upgrading Elasticsearch data store on Linux on Power (ppc64le)

Make sure that you prepared your online and offline host to pull images from the external repository. Also, ensure that you added the Helm repo.

The following images are needed for the pinned Helm chart or operator versions.

Platform	Operator versions	Helm chart version	Image with tag
Linux® on Power® (ppc64le)	3.4.1	3.4.1	artifact-public.instana.io/self-hosted-images/3rd-party/operator/elasticsearch:3.4.1_v0.34.0 artifact-public.instana.io/self-hosted-images/3rd-party/datastore/elasticsearch:8.19.13_v0.40.0

Complete these steps to upgrade Elasticsearch data store.

1. Upgrade Elasticsearch operator.

   helm upgrade --install elastic-operator instana/eck-operator -n instana-elastic --version=3.4.1 --set image.repository=artifact-public.instana.io/self-hosted-images/3rd-party/operator/elasticsearch --set image.tag=3.4.1_v0.34.0 --set imagePullSecrets[0].name="instana-registry"
    

2. Update Elasticsearch by patching Elasticsearch configuration.

   kubectl patch elasticsearch instana -n instana-elastic --type=merge --patch '
   spec:
     version: 8.19.13
     image: artifact-public.instana.io/self-hosted-images/3rd-party/datastore/elasticsearch:8.19.13_v0.40.0
     '
    

3. Complete the steps in Verifying Elasticsearch (online and offline).

If you didn't yet pull the Elasticsearch images from the external registry, you can pull them now. Run the following commands on your bastion host. Then, copy the images to your Instana host that is in your air-gapped environment.

docker pull artifact-public.instana.io/self-hosted-images/3rd-party/operator/elasticsearch:3.4.1_v0.34.0
docker pull artifact-public.instana.io/self-hosted-images/3rd-party/datastore/elasticsearch:8.19.13_v0.40.0
         

Complete the following steps on your Instana host.

1. Retag the images to your internal image registry.

   docker tag artifact-public.instana.io/self-hosted-images/3rd-party/operator/elasticsearch:3.4.1_v0.34.0 <internal-image-registry>/ppc64le-oss/eck-operator-ppc64le:3.4.1_v0.34.0
   docker tag artifact-public.instana.io/self-hosted-images/3rd-party/datastore/elasticsearch:8.19.13_v0.40.0 <internal-image-registry>/ppc64le-oss/elasticsearch-ppc64le:8.19.13_v0.40.0
                  

2. Push the images to your internal image registry on your bastion host.

   docker push <internal-image-registry>/self-hosted-images/3rd-party/operator/elasticsearch:3.4.1_v0.34.0
   docker push <internal-image-registry>/ppc64le-oss/elasticsearch-ppc64le:8.19.13_v0.40.0
                  

3. Upgrade Elasticsearch operator.

   helm upgrade --install elastic-operator eck-operator-3.4.1.tgz -n instana-elastic --set image.repository=<internal-image-registry>/self-hosted-images/3rd-party/operator/elasticsearch --set image.tag=3.4.1_v0.34.0
                  

4. Update Elasticsearch by patching Elasticssearch configuration.

   kubectl patch elasticsearch instana -n instana-elastic --type=merge --patch '
   spec:
     version: 8.19.18
     image: artifact-public.instana.io/self-hosted-images/3rd-party/datastore/elasticsearch:8.19.18_v0.37.0
     '
    

5. Complete the steps in Verifying Elasticsearch (online and offline).

To verify Elasticsearch instance adata store, complete the following steps:

1. Wait for Elasticsearch.

   kubectl wait elasticsearch/instana --for=condition=ReconciliationComplete --timeout=300s -n instana-elastic
    

2. Verify Elasticsearch operator upgrade.

    kubectl get all -n instana-elastic
    

   If the Elasticsearch operator is upgraded successfully, the command output shows the operator status as Running as shown in the following example:
