Validate the Upgrade

7 Validate the Upgrade

Validate the upgrade from Oracle CNE Release 1 to Release 2 succeeded, and that all nodes in the Kubernetes cluster are running the Release 2 OS.

List the nodes in the cluster.
List the nodes in the Kubernetes cluster to ensure all expected nodes are listed.
```
kubectl get nodes
```
Confirm each node STATUS is listed as Ready.
Show information about the cluster.
Use the ocne cluster info command to display information about the cluster. The syntax is:
```
ocne cluster info
[{-N|--nodes}] nodename, ...
[{-s|--skip-nodes }]
```
For more information on the syntax options, see Oracle Cloud Native Environment: CLI.

For example:
```
ocne cluster info
```

Validate the cluster information.

All nodes in the cluster are running the Release 2 image if the output of the ocne cluster info command looks similar to:

...
Node: ocne-control-plane-1
  Registry and tag for ostree patch images:
    registry: container-registry.oracle.com/olcne/ock-ostree
    tag: 1.29
    transport: ostree-unverified-registry
  Ostree deployments:
      ock 5d6e86d05fa0b9390c748a0a19288ca32bwer1eac42fef1c048050ce03ffb5ff9.1 (staged)
    * ock 5d6e86d05fa0b9390c748a0a19288ca32bwer1eac42fef1c048050ce03ffb5ff9.0

Node: ocne-control-plane-2
  Registry and tag for ostree patch images:
    registry: container-registry.oracle.com/olcne/ock-ostree
    tag: 1.29
    transport: ostree-unverified-registry
  Ostree deployments:
      ock 5d6e86d05fa0b9390c748a0a19288ca32bwer1eac42fef1c048050ce03ffb5ff9.1 (staged)
    * ock 5d6e86d05fa0b9390c748a0a19288ca32bwer1eac42fef1c048050ce03ffb5ff9.0
...

If any of the nodes aren't running the Release 2 image, the output doesn't include the registry and OSTree information, for example:

...
Node: ocne-control-plane-1
  Registry and tag for ostree patch images:
    registry: container-registry.oracle.com/olcne/ock-ostree
    tag: 1.29
    transport: ostree-unverified-registry
  Ostree deployments:
      ock 5d6e86d05fa0b9390c748a0a19288ca32bwer1eac42fef1c048050ce03ffb5ff9.1 (staged)
    * ock 5d6e86d05fa0b9390c748a0a19288ca32bwer1eac42fef1c048050ce03ffb5ff9.0

Node: ocne-control-plane-2

Verify the list of available applications.
Use the ocne catalog search command to see the list of applications available in the Oracle catalog. The syntax is:
```
ocne catalog search 
[{-N|--name} name]
[{-p|--pattern} pattern]
```
For more information on the syntax options, see Oracle Cloud Native Environment: CLI.

For example, to list all the applications available in the Oracle catalog:
```
ocne catalog search
```
Ensure all expected applications are available. Verify all Release 1 modules are listed as applications.
Verify the list of installed applications.
Use the ocne application list command to see the list of applications installed in the cluster. The syntax is:
```
ocne application {list|ls} 
[{-A|--all}]
[{-n|--namespace} namespace]
```
For more information on the syntax options, see Oracle Cloud Native Environment: CLI.

For example, to list all the applications installed in the cluster:
```
ocne application list --all
```
Ensure all expected installed applications are listed.
