Multiple deployment issues due to readonly tmp #371
Description
Bug Report
Problematic behavior
Meet (backend and frontend) is not able to be deployed in a fresh demo setup because of the readonly root filesystem.
Expected behavior/code
Demo deployment should work out of the box
Steps to Reproduce
- Fresh setup using the demo environment
Environment
- Product version: Git main branch, 11 Jan
- Platform: Barebones K8s
Possible Solution
Add something along the lines of
volumeMounts:
- name: empty-dir
mountPath: /tmp
subPath: tmp-dir
volumes:
- name: empty-dir
emptyDir: {}
