4 Upgrading OCNRF

This section includes information about upgrading an existing OCNRF deployment.

Note:

IF YOU HAVE ENABLED SERVICE MESH THEN YOU HAVE TO PERFORM FRESH INSTALLATION OF OCNRF. YOU CANNOT UPGRADE FROM OCNRF 1.7.0 TO OCNRF 1.7.2.

When you attempt to upgrade an existing OCNRF deployment, the running set of containers and pods are replaced with the new set of containers and pods. However, If there is no change in the pod configuration, the running set of containers and pods are not replaced.

If you need to change any configuration then change the ocnrf-custom-values-1.7.2.yaml file with new values.

Note:

It is advisable to create a backup of the file before changing any configuration.

To configure the parameters, see section OCNRF Configuration.

Caution:

OCNRF 1.7.2 upgrade supports changing HELM configurable parameters only.
Execute the following command to upgrade an existing OCNRF deployment: 
$ helm upgrade <release> <helm chart> [--version <OCNRF version>] -f <ocnrf_customized_values.yaml>

For example:

$ helm upgrade <release> <helm chart> [--version <OCNRF version>] -f ocnrf-custom-values-1.7.2.yaml

To check the status of the upgrade, execute: 

helm status <helm-release>

For example: helm status ocnrf
