📝 Walkthrough

Walkthrough

Updates Docker Compose configuration documentation by adding three Linux capabilities (CHOWN, SETUID, SETGID) to service capabilities. These capabilities enable the root-entrypoint script to manage filesystem permissions on /data and /tmp directories and facilitate privilege dropping to a non-root user/group.

Changes

Cohort / File(s)	Summary
Docker Configuration Documentation docs/DOCKER_COMPOSE.md	Adds CHOWN, SETUID, and SETGID Linux capabilities to Docker Compose service configuration for permission management and privilege escalation control

Poem

🐰 In Docker's realm where permissions take flight,
Three powers granted to set things right,
CHOWN and SETUID dance with grace,
SETGID joins the privileged space,
Root can manage, then step away bright! ✨
