This documentation covers Poweradmin 4.0.x, 4.1.x, and 4.2.x. Some sections are still being expanded.

Docker Installation

Poweradmin provides official Docker images for easy deployment with FrankenPHP.

Docker Images

Official images are available at:

Docker Hub: poweradmin/poweradmin
GitHub Container Registry: ghcr.io/poweradmin/poweradmin

Image Tags

Tag	Description
`stable`	Stable release from `release/4.2.x` (recommended for production)

Secrets

    file: ./secrets/db_password.txt

services:
  poweradmin:
    environment:
      DB_PASS__FILE: /run/secrets/db_password
    secrets:
      - db_password

Non-Root / Rootless Deployment

The Poweradmin image supports running as a non-root user for restricted Kubernetes clusters and OpenShift. No separate image variant is needed - the entrypoint adapts automatically.

Behavior

Start mode	Port	Privileges	Use case
Root (default)	80	Drops to www-data after setup	Standard Docker, unrestricted K8s
Non-root	8080 (auto)	No chown/chmod/CA install	Restricted K8s, OpenShift

Docker (Non-Root)

docker run --rm --user 82:82 -p 8080:8080 \
  -e DB_TYPE=sqlite \
  poweradmin/poweradmin:stable

Kubernetes (Restricted)

spec:
  securityContext:
    runAsNonRoot: true
    runAsUser: 82
    runAsGroup: 82
    fsGroup: 82
  containers:
    - name: poweradmin
      image: poweradmin/poweradmin:stable
      ports:
        - containerPort: 8080
      securityContext:
        allowPrivilegeEscalation: false
        capabilities:
          drop: ["ALL"]
      env:
        - name: DB_TYPE
          value: sqlite

fsGroup: 82 ensures volumes are group-writable for www-data (GID 82).

Custom Port

Override the auto-detected port with SERVER_PORT:

docker run --rm -e SERVER_PORT=9090 -p 9090:9090 poweradmin/poweradmin

Limitations (Non-Root)

TRUSTED_CA_FILE requires root - a warning is logged if set in non-root mode
Volumes must be pre-configured as writable (use fsGroup or host permissions)

Troubleshooting

Check container logs

docker logs poweradmin

Access container shell

docker exec -it poweradmin /bin/sh

Database connection issues

Verify database is accessible from container
Check credentials are correct
Ensure database exists and user has permissions

Permission issues with volumes

docker run --user root ...
# or fix permissions on host
sudo chown -R 1000:1000 /path/to/volume
