Bug description

Hi Team,
I want to run rstudio server (free version) on kubernetes. If I'm taking wrong approach here, please guide me on how to do the setup in kubernetes.
I'm using the image rocker/rstudio:4.4.2 and trying to run it as nonRoot user. (same noted with image rocker/tidyverse:4.4.2)
The pod spec is as follows

spec:
      securityContext:
        runAsNonRoot: true
        runAsUser: 1001
        runAsGroup: 1001
        seccompProfile:
          type: RuntimeDefault
      containers:
      - name : rstudio
        image:  rocker/tidyverse:4.4.2
        env:
          - name: USERID
            value: "1001"
          - name: GROUPID
            value: "1001"
        securityContext:
          allowPrivilegeEscalation: false
        resources:  
          requests:
            memory: "200Mi"  
            cpu: "3000m"     
          limits:
            memory: "5000Mi"

The container is failing to start with below error
s6-overlay-preinit: fatal: unable to mkdir /var/run/s6: Permission denied

Reference to discussion forum on same issue: https://forum.posit.co/t/rstudio-server-in-kubernetes/195626/4

Can you help in addressing the issue.

How to reproduce this bug?

Run a pod with above mentioned spec. The container fail to startup.
