## What and why to refactor
What are you trying to refactor? Why should it be refactored now?
Updating the base Dockerfiles for:
- devlake/backend
- devlake-config-ui
- devlake/grafana
On OpenShift, pod security constraints forbid containers to switch away from
arbitrary UIDs unless the group is
root (GID 0). Our current images:
```
FROM apache/devlake:v1.0.2
USER root
RUN chgrp -R 0 /app && \
chmod -R g=u /app
USER devlake
```
```
FROM apache/devlake-config-ui:v1.0.2
USER root
RUN chgrp -R 0 /etc/nginx /var/log/nginx /usr/share/nginx /run && \
chmod -R g=u /etc/nginx /var/log/nginx /usr/share/nginx /run
USER 101
```
— while functionally correct — will be blocked by “MustRunAsNonRoot”
policies on clusters that enforce GID 0 ownership for writable volumes. We need
all processes (running under a random UID) to belong to GID 0 and have group‑rw
permissions on the directories they must write to.
## Describe the solution you'd like
How to refactor?
1. Switch to a non‑root base user
Make sure USER devlake is the default at the end of the Dockerfile.
2. Set group ownership to root (0)
For every directory the app writes to (e.g. /app, /config, /data, etc.), add:
```
Copy
Edit
USER root
RUN chgrp -R 0 /app /config /data \
&& chmod -R g=u /app /config /data
USER devlake
```
This aligns exactly with the [OpenShift Container Platform
guidelines](https://docs.openshift.com/container-platform/4.5/openshift_images/create-images.html#images-create-guide-openshift_create-images).
3. Update documentation
Mention that these builds are now fully compatible with OpenShift’s
restricted SCC.
