4 NRF Upgrade

This section includes information about upgrading an existing NRF deployment.

When you attempt to upgrade an existing NRF 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-1.0.0.yaml file with new values.

Note:

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

To configure the parameters, see section NRF Configuration

Execute the following command to upgrade an existing NRF deployment:

helm upgrade <release> -f ocnrf-custom-values-1.0.0.yaml
