docker-openvpn

Simple OpenVPN image with updated version, optimized for privacy-focused VPN services.

Using the image

There is no default config provided by the image, so you'll need to provide your own.

docker run -d -n openvpn -v /path/to/openvpn.conf:/etc/openvpn/openvpn.conf ghcr.io/blinklabs-io/openvpn --config /etc/openvpn/openvpn.conf

The image provides for the ability to provide a custom startup script. It looks for a user script at /usr/local/bin/entrypoint-user.sh by default, but the location can be overridden with the USER_STARTUP_SCRIPT environment variable

Privacy and Security Recommendations

For a no-log, privacy-focused setup:

OpenVPN Configuration

Use these options in your openvpn.conf for strong encryption and no logging:

# Disable logging
log /dev/null
verb 0

# Strong ciphers
cipher AES-256-GCM
auth SHA256
tls-cipher TLS-ECDHE-RSA-WITH-AES-256-GCM-SHA384
tls-version-min 1.2

# Privilege drop
user nobody
group nogroup

# Other privacy settings
persist-key
persist-tun

Docker Run Options

• Use Docker secrets for certificates/keys: --secret mykey=/path/to/key
• Run with necessary capabilities only: --cap-add=NET_ADMIN (avoid --privileged)
• For Kubernetes (Helm), use securityContext to limit privileges.

Maintenance

• Rebuild images regularly to pull security updates from Debian repos.
• Scan for vulnerabilities with tools like Trivy (automated via GitHub Actions).
• Test for leaks using services like ipleak.net while connected.

Warning: Running in privileged mode increases security risks—use only when necessary.
