1-4: Consider adding context about benefits of read-only filesystemsThe introduction could be enhanced by briefly explaining the security and operational benefits of using read-only filesystems (e.g., improved security posture, container immutability, compliance requirements).
# Read-only File Systems Support for read-only file systems is available from version 9.0.0 + +Read-only filesystems provide enhanced security by preventing runtime modifications to the container's filesystem, ensuring container immutability, and helping meet security compliance requirements.
15-21: Consider adding Kubernetes configuration examplesWhile the instructions mention Kubernetes, providing a concrete example would make implementation easier for users.
Set both the Server and Worker images to run with read-only file systems (e.g. `readOnlyRootFilesystem` in Kubernetes). +Example Kubernetes configuration: +```yaml +securityContext: + readOnlyRootFilesystem: true +volumeMounts: + - name: tmp + mountPath: /tmp +volumes: + - name: tmp + emptyDir: {} +```
30-32: Consider adding specific testing steps and validation criteriaThe success criteria could be more detailed to help users verify their setup is working correctly.
## Testing and release The measure of success is that all packager managers succeed (e.g. at updating lock files) using the read-write volumes only. + +Recommended validation steps: +1. Configure a test repository with various package managers (npm, pip, golang, etc.) +2. Run Renovate with read-only filesystem enabled +3. Verify that dependency updates complete successfully +4. Check logs for any filesystem-related errors +5. Confirm that no writes occur outside the designated read-write volumes

25-28: Risk description and mitigation strategy is well explained
The explanation of risks and mitigation strategies is clear and helpful. The suggestion to use environment variables for directing package managers to write to /tmp/renovate is a good practice.

13-13: Consider adding a Kubernetes exampleThe reference to
readOnlyRootFilesystemin Kubernetes would be clearer with a practical example.Consider adding a snippet like:
securityContext: readOnlyRootFilesystem: true
25-26: Consider adding specific environment variable examplesThe mention of environment variables would be more helpful with concrete examples of how to configure package managers to write to
/tmp/renovate.
28-30: Consider adding specific testing stepsThe testing criteria could be enhanced with:
- Step-by-step verification process
- Common failure scenarios to watch for
- Troubleshooting guidelines
