Testing

Tested on:

• Mug, Tyr, Fanta, Gamora

Test description:

I have installed the package via helm on Mug to insure the upgrade/downgrade worked correctly and tested changing the ims-config settings and verified they flowed through to the job settings as they should. This also verified the alpine base image change. The cpu limits were tested on a whole bunch of different systems as problems were encountered.

• Were the install/upgrade-based validation checks/tests run (goss tests/install-validation doc)? N
• Were continuous integration tests run? If not, why? N
• Was upgrade tested? If not, why? Y
• Was downgrade tested? If not, why? Y
• Were new tests (or test issues/Jiras) created for this change? N

Risks and Mitigations

Fairly low risk changes - just tweaks to settings for the most part that have been tested.
