Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.
  • All Bitnami images available in Docker Hub are signed with Docker Content Trust (DTC). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
  • Bitnami container images are released daily with the latest distribution packages available.

This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Configuration

Using a configuration file

The configuration can easily be setup by mounting your own configuration file on the directory /opt/bitnami/keycloak-gatekeeper/conf (both JSON and YAML formats are supported: config.json or config.yaml).

$ docker run --name keycloak-gatekeeper \
  --volume /path/to/config.yaml:/opt/bitnami/keycloak-gatekeeper/config.yaml \
  bitnami/keycloak-gatekeeper:latest \
  /keycloak-gatekeeper --config /opt/bitnami/keycloak-gatekeeper/config.yaml

After that, your configuration will be taken into account in Keycloak Gatekeeper.

You can do this using Docker Compose by modifying the docker-compose.yml file present in this repository:

keycloak-gatekeeper:
  ...
  command: /keycloak-gatekeeper --config /opt/bitnami/keycloak-gatekeeper/config.yaml
  volumes:
    - /path/to/config.yaml:/opt/bitnami/keycloak-gatekeeper/config.yaml:ro
  ...

Using command-line options

The configuration can also be setup by providing command-line options.

$ docker run --name keycloak-gatekeeper bitnami/keycloak-gatekeeper:latest /keycloak-gatekeeper \
  --listen 127.0.0.1:3000 \
  --upstream-url http://127.0.0.1:80 \
  --discovery-url https://keycloak.example.com/auth/realms/<REALM_NAME> \
  --client-id <CLIENT_ID>

keycloak-gatekeeper:
  ...
  command:
    - /keycloak-gatekeeper
    - --listen
    - 127.0.0.1:3000
