# Docker User and Permission Check
Analyze Docker configurations for user, ownership, and permission issues in PHP containers.
## Permission Check Patterns
| Check | Risk | Detection |
|-------|------|-----------|
| No USER instruction | Root execution | Missing `USER` in Dockerfile |
| Wrong UID/GID | Permission conflicts | Non-standard user IDs |
| COPY without --chown | Root-owned files | `COPY` without ownership |
| chmod 777 | World-writable files | Overly permissive mode |
| Volume permission mismatch | Read/write failures | Host vs container UID |
| Read-only FS incompatibility | Runtime crashes | Missing tmpfs for writable dirs |
