Upgrading the Helm deployment

This topic provides detailed steps for upgrading the Helm deployment using an updated custom-values.yaml file.

1. Retrieve the current custom-values.yaml file from a previous deployment or by using the following command:

   helm get values <RELEASE-NAME> -n <NAMESPACE> -o yaml > custom-values.yaml
   

   For example, to retrieve the custom-values.yaml file of modified values, use the following command:

   helm get values dx-deployment -n dxns -o yaml > custom-values.yaml
   

   To retrieve the full custom-values.yaml file that includes the default values, use the following command:

   helm get values dx-deployment -n dxns  -o yaml  -a > custom-values-all.yaml
   

2. Update the custom-values.yaml file with the required changes (for example, configOverrideFiles, images).

3. Upgrade the Helm deployment with the updated custom-values.yaml file.

   Use the following command to apply the updates to your Helm deployment:

   helm upgrade <RELEASE_NAME> -n <NAMESPACE> -f custom-values.yaml <HELM_CHART_DIRECTORY>
   

   For example:

   helm upgrade dx-deployment  -n dxns -f custom-values.yaml mycharts/install-hcl-dx-deployment
