Use ephemeral PVC for JENKINS_HOME

[tomvopat]

Describe the solution you'd like
For big projects with many jobs and many archived logs, it can happen that JENKINKS_HOME directory takes all the node's disk capacity as it is of type emptyDir. Using an ephemeral PVC for JENKINS_HOME would solve this issue.

Yep agree this is something we should implement to avoid evicted pods and not ready nodes due to disk pressure.

Do I need to make the changes in the default configuration or make a new one separately?

[tomvopat]

Can you elaborate a bit? I'm not sure what you mean...

@brokenpip3 Is this being worked on? Having a PVC for jenkins home directory would really be useful.

[brokenpip3]

Hi @dashashutosh24 this is not a pvc for the home directory, it's just using ephemeral pvc instead of emptydir as home directory (#779 (comment)).
If you want to have a persistent volume for the whole home directory you can use the official jenkins helm chart :)
Maybe in the future we may add a small portion of the home directory like secrets but it's not planned yet.
Coming back to the issue original request: I want to work on this soon :)

@brokenpip3 Thanks for the response. Just a quick question, I tried mounting a PV at /var/lib/jenkins/secrets to preserve the secrets to allow agent reconnection after master comes back up once its down. But still the agent wasn't able to connect to the master. This is in relation to #691 . Any idea how to tackle this?
