Best practices for writing Dockerfiles follow

Just some reminders :

Run only one process in a container.
Never run a process as root in a container.
Never store data in a container, do it in a volume
Never store credentials in a container, do it in a volume
Keep your image up to date
Verify third-party container repositories
Use tool like docker-security-scanning
May the force be with you 🙏
