Running the Upgrade

1. On the bastion, verify that all pods in core namespaces are in status Running or Completed by running this command:

   kubectl get pods -n core

   Output example:

   cdf-apiserver-7965dcf689-4qvkx                         2/2     Running     0          145m

   itom-cdf-deployer-2020.05-2.2-2.3-3.1-tncp8            0/1     Completed   0          137m

   itom-cdf-deployer-xg6cw                                0/1     Completed   0          147m

   itom-cdf-ingress-frontend-56c9987b7-bvrsn              2/2     Running     0          145m

   itom-cdf-ingress-frontend-56c9987b7-n8tbc              2/2     Running     0          145m

   itom-logrotate-deployment-6cf9546f8b-rbcvs             1/1     Running     0          136m

   itom-postgresql-default-77479dfbff-t87tv               2/2     Running     0          137m

   itom-vault-6f558dc6cc-bz52l                            1/1     Running     0          146m

   nginx-ingress-controller-6f6d4c95b9-nv2zw              2/2     Running     0          133m

   suite-db-68bfc4fbd5-v6nvm                              2/2     Running     0          145m

2. Patch itom-cdf-ingress-frontend-svc and nginx-ingress-controller-svc as type LoadBalancer by running the following commands:
   

   kubectl patch services itom-cdf-ingress-frontend-svc \
   -p '{"metadata":{"annotations":{"service.beta.kubernetes.io/aws-load-balancer-internal":"0.0.0.0/0","service.beta.kubernetes.io/aws-load-balancer-type":"nlb"}},"spec":{"type":"LoadBalancer"}}' -n core

   kubectl patch services nginx-ingress-controller-svc \
   -p '{"metadata":{"annotations":{"service.beta.kubernetes.io/aws-load-balancer-internal":"0.0.0.0/0","service.beta.kubernetes.io/aws-load-balancer-type":"nlb"}},"spec":{"type":"LoadBalancer"}}' -n core
   

3. Wait until the command status in Step 2 changes from <pending>, and then run the following commands to get the load balancer DNS names:

   kubectl get svc itom-cdf-ingress-frontend-svc -n core| grep -v EXTERNAL-IP |awk '{print $4}'
   kubectl get svc nginx-ingress-controller-svc -n core| grep -v EXTERNAL-IP |awk '{print $4}'

4. Switch directory to cdf-deployer directory:
   cd /tmp/
5. Unzip cdf-deployer.zip:
   unzip cdf-deployer.zip
6. Switch to the cdf-deployer directory:
   cd cdf-deployer/

7. Run the upgrade script with the following command:

   ./upgrade.sh -u

   Output example:

   ***********************************************************************************

   WARNING: This step is used to upgrade CDF components to 2021.02 release.

   The upgrade process is irreversible. You can NOT roll back.

   Make sure that all nodes in your cluster are in Ready status.

   Make sure that all Pods and Services are Running.

8. When the upgrade completes, check that all pods are Running or Completed with this command:
   kubectl get pods -A

The CDF upgrade is now complete. The new platform version can be checked by running this command:
kubectl get cm base-configmap -o yaml -n core | grep VERSION
