Check Environment and Determine Upgrade Method

Audience: System Administrators

Content Summary: This guide outlines the process for upgrading Helm installations of Immuta in Kubernetes.

  • Method A is for basic upgrades and is typically acceptable when moving between minor point releases of Immuta (such as 2.7.0 to 2.7.1).
  • Method B is a more involved method that leverages a full backup and restore procedure. This approach is needed when conducting more significant upgrades such as major releases (such as 2.6.x to 2.7.x), when making large jumps in versions (for example going from 2.5.x to 2.7.x), or simply whenever advised by your Immuta professional.

Method B can be used in all cases.

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:

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.

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 and instructions to set up both of these by accessing the Immuta Release Portal.

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

helm repo list
NAME            URL
If you do not create a Kubernetes Image Pull Secret, installation will fail.

As detailed in Immuta Release Portal, 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        1      5s

1.3 - Check/Update Your Local Immuta Helm Chart Version

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

helm search repo immuta
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
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
