Upgrade Helm

If using a Kubernetes namespace...

If deploying Immuta into a Kubernetes namespace other than the default, you must include the --namespace option into all helm and kubectl commands provided throughout this section.

Helm Upgrade Process

  1. Check Environment

  2. Determine Upgrade Path:

1 - Check Environment

1.1 - Check Helm Version

  • Immuta's Helm Chart requires Helm version 2.16+ or 3+.
  • Helm 2.16+ is only supported for existing Immuta installations.
  • New installations of Immuta must use the latest version of Helm 3 and Immuta's latest Chart.

Run helm version to verify the version of Helm you are using:

helm version

version.BuildInfo{Version:"v3.0.2", GitCommit:"19e47ee3283ae98139d98460de796c1be1e3975f", GitTreeState:"clean", GoVersion:"go1.13.5"}

Client: &version.Version{SemVer:"v2.16.1", GitCommit:"bbdfe5e7803a12bbdf97e94cd847859890cf4050", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.16.1", GitCommit:"bbdfe5e7803a12bbdf97e94cd847859890cf4050", GitTreeState:"clean"}
If using Helm 2, ensure your Helm version matches Tiller in the cluster

Keeping your Helm version matched to your Tiller version is best practice and can avoid incompatibility issues. Run helm version to compare versions and ensure sync.

$ helm version
Client: &version.Version{SemVer:"v2.16.1", GitCommit:"bbdfe5e7803a12bbdf97e94cd847859890cf4050", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.16.1", GitCommit:"bbdfe5e7803a12bbdf97e94cd847859890cf4050", GitTreeState:"clean"}

1.2 - Configure Immuta's Helm Chart Repo

In order to deploy Immuta to your Kubernetes cluster, you must be able to access the Immuta Helm Chart Repository and the Immuta Docker Registry. You can obtain credentials from your Immuta support professional.

Run helm repo list to ensure Immuta's Helm Chart repository has been successfully added:

helm repo list

NAME            URL
stable          https://kubernetes-charts.storage.googleapis.com
local           http://127.0.0.1:8879/charts
immuta          https://archives.immuta.com/charts
If you do not create a Kubernetes Image Pull Secret, installation will fail.

You must create a Kubernetes Image Pull Secret in the namespace that you are deploying Immuta in, or the installation will fail.

Run kubectl get secrets to confirm your Kubernetes image pull secret is in place:

kubectl get secrets

NAME                  TYPE                                  DATA   AGE
immuta-registry       kubernetes.io/dockerconfigjson        1      5s

1.3 - Check/Update Your Local Immuta Helm Chart Version

No Rollback

Immuta's migrations to your database are one way; this means that there is no way to revert back to an earlier version of the software. If you must rollback, you will need to backup and delete what you have and then proceed to restore from the backup to the appropriate version of the software.

No Modifying Persistence

Once persistence is set to either true or false for the database or query-engine, it cannot be changed for the deployment. Modifying persistence will require a fresh installation or a full backup and restore procedure as per Method B: Complete Backup and Restore Upgrade.

Run helm search repo immuta to check the version of your local copy of Immuta's Helm Chart:

helm search repo immuta

NAME          CHART VERSION APP VERSION DESCRIPTION
immuta/immuta 4.4.1         2.7.0       The Immuta

Update your local Chart by running helm repo update.

To perform an upgrade without upgrading to the latest version of the Chart, run helm list to determine the Chart version of the installed release, and then specify that version using the --version argument of helm repo update.

1.4 - Confirm Connectivity with Your Current Immuta Helm Installation

Run helm list to confirm Helm connectivity and verify the current Immuta installation:

helm list

NAME  REVISION  UPDATED                   STATUS    CHART         APP VERSION NAMESPACE
test  1         Tue Dec 17 01:04:36 2019  DEPLOYED  immuta-4.2.3  2.6.0       ns

Make note of:

  • NAME - This is the '<YOUR RELEASE NAME>' that will be used in the remainder of these instructions.
  • CHART - This is the version of Immuta's Helm Chart that your instance was deployed under.

1.5 - Confirm Access to the Helm Values Used in Your Current Immuta Installation

You will need the Helm values associated with your installation, which are typically stored in an immuta-values.yaml file. If you do not possess the original values file, these can be extracted from the existing installation using:

helm get values <YOUR RELEASE NAME> > immuta-values.yaml

2 - Determine Your Upgrade Path

Select your method:

Rocky Linux 9

Review the potential impacts of Immuta's Rocky Linux 9 upgrade to your environment before proceeding.

After you make any desired changes in your immuta-values.yaml file, you can apply these changes by running helm upgrade:

helm upgrade <YOUR RELEASE NAME> immuta/immuta \
    --values immuta-values.yaml
    --version <YOUR DESIRED CHART VERSION>

Note: Errors in upgrades can result when upgrading Chart versions on the installation. These are typically easily resolved by making slight modifications of your values to accommodate the changes in the Chart. Downloading an updated copy of the immuta-values.yaml and comparing to your existing values is often a great way to debug such occurrences.

If you are on Kubernetes 1.22+, remove nginxIngress.controller.image.tag=v0.49.3 when upgrading; otherwise, your ingress service may not start after the upgrade.
