How to Upgrade Pachyderm #
1. Run a Preflight Check #
PachD has a preflight check mode that you can enable in your Helm chart by setting pachd.preflightchecks.enabled to true. Preflight checks run as a Kubernetes job, and can use a different version of Pachyderm than the rest of the chart. In this case, you will set it to the version you are upgrading to (for example, the latest version is 2.7.4).
Example configuration:
preflightCheckJob:
enabled: true
image:
tag: "2.7.4"
You’ll see a pod named pachyderm-preflight-check was created to perform the preflight checks.
- If its status says
completed, you are ready to continue with the upgrade. - If its status does not say
completed, reach out to the Pachyderm team for assistance with your upgrade.
