AdGuardHome: rootless, distroless, secure by default
These are the main tags for the image. There is also a tag for each commit and its shorthand sha256 value.
What can I do with this? Block most ads from most websites, have entire categories blocked on your or other networks or for individual clients. Perfect for parents and enterprises alike.
Why should I run this image and not the other image(s) that already exist? Good question! All the other images on the market that do exactly the same don’t do or offer these options:
Important
- This image runs as 1000:1000 by default, most other images run everything as root
- This image has no shell since it is 100% distroless, most other images run on a distro like Debian or Alpine with full shell access (security)
- This image does not ship with any critical or high rated CVE and is automatically maintained via CI/CD, most other images mostly have no CVE scanning or code quality tools in place
- This image is created via a secure, pinned CI/CD process and immune to upstream attacks, most other images have upstream dependencies that can be exploited
- This image contains a patch to run rootless (Linux caps needed), most other images require higher caps
- This image contains a proper health check that verifies the app is actually working, most other images have either no health check or only check if a port is open or ping works
- This image works as read-only, most other images need to write files to the image filesystem
If you value security, simplicity and the ability to interact with the maintainer and developer of an image. Using my images is a great start in that direction.

The configuration will be updated with your settings if you use the mentioned volumes below. It is recommended to always add the exception for dnslookup.

Important
This image is not based on another image but uses scratch as the starting layer. The image consists of the following distroless layers that were added:
- 11notes/distroless - contains users, timezones and Root CA certificates
- 11notes/distroless:dnslookup - app to execute DNS queries
Tip
- Use a reverse proxy like Traefik, Nginx, HAproxy to terminate TLS and to protect your endpoints
- Use Let’s Encrypt DNS-01 challenge to obtain valid SSL certificates for your services
Caution
- This image comes with a default SSL certificate. If you plan to expose the web interface via HTTPS, please replace the default certificate with your own.
- This image comes with a default configuration with a default password for the admin account. Please set your own password or provide your own configuration.
This image is provided to you at your own risk. Always make backups before updating an image to a different version. Check the releases for breaking changes. If you have any problems with using this image simply raise an issue, thanks. If you have a question or inputs please create a new discussion instead of an issue. You can find all my other repositories on github.
