Upgrading a Grainite Cluster

Grainite releases periodic updates that are available to customers through our repositories. Please follow the below instructions to perform a cluster upgrade.

Prerequisite

First, check the release notes for the target version you will be upgrading to as well as all versions in between to ensure you are aware of any backwards-incompatible changes or helm chart or config updates that were made between versions. If there are, you will need to perform intermediate upgrades to those versions in ascending order before finally upgrading to the desired version.

How to set Grainite cluster image version using kubectl

Then, run the below command.

kubectl edit sts

Then search for your Grainite image version (e.g. cluster:2318) and replace it with the new version (e.g. cluster:2319).

Save this new setting and the rolling upgrade will begin.
