Regular Software Updates¶

There are various software stacks that should be updated regularly. This document describes the intervals and procedures.

All kubernetes based applications should be updated in a 2 step manner:

Create a ticket in the datacenterlight project for the update
Create or update apps/dev/APPNAME in k8s-config
Create or update a test instance in the kubernetes cluster that is using apps/dev/APPNAME
Ensure the test instance is running properly
Apply changes from apps/dev/APPNAME to apps/prod/APPNAME
Ensure all production instances are applying and working properly

Schedule: all apps should be checked for new updates at least once per month.
