Dex Overview
Secure your stack with a hardened Dex image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.
Use the Dex container image to set up an identity service that uses OpenID Connect Identity (OIDC) or OAuth 2.0 with connectors.
Try It Out
Take the Minimus Dex image for a test run by looking up its version information:
docker run --rm \
reg.mini.dev/dex dex versionThe version information printout should like this:
Dex Version: v2.43.1
Go Version: go1.24.4
Go OS/ARCH: linux amd64Ready to mount a custom configuration?
You can test the image with a sample configuration file. First, download the sample config.docker.yaml file to your project directory.
About the sample configuration:
- Uses
{HOST_IP}as a placeholder. Replace it with your local IP address. (To look up your local internal IP address runifconfigin Linux oripconfigin Windows.) - Uses sqlite3 but you can bind your own storage instead.
- Enables
insecureNoSSLbut you can disable it. - Uses a hardcoded secret for the demo. This is not recommended for any other use case.
Run the container with port 5556 exposed:
docker run --rm -d \
-p 5556:5556 \
-v ./config.docker.yaml:/dex/config.docker.yaml \
reg.mini.dev/dexVisit http://0.0.0.0:5556/dex in your web browser to view the Dex dashboard. Alternatively, run curl http://0.0.0.0:5556/dex to get around firewall restrictions if you encounter them.
Deploy via a Helm chart
Dex can also be deployed via Helm charts. See the related charts tab to get started.
Technical Considerations
The Dex image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.
Dex built by Minimus:
- Runs as non-root by default as user 1001. The public image runs as user 1001.
- Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.
The Payoff
A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.
- See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
- Review the compliance report to see the default hardening and security configurations for the image.
