ForgeOps

Base Docker images

ForgeRock provides 12 Docker images for deploying the ForgeRock Identity Platform:

  • Seven unsupported, evaluation-only base images:

    • amster

    • am-cdk

    • am-config-upgrader

    • ds

    • idm-cdk

    • ig

    • java-17

  • Five supported base images that implement the platform’s user interface elements and ForgeOps operators:

    • ds-operator

    • platform-admin-ui

    • platform-enduser-ui

    • platform-login-ui

    • secret-agent

The Docker images are publicly available in ForgeRock’s Docker repository, gcr.io/forgerock-io.

Before you begin building custom images, ensure that you are using Java version 17 on your computer. For example:

$ java --version
openjdk 17.0.10 2024-01-16
OpenJDK Runtime Environment Temurin-17.0.10+7 (build 17.0.10+7)
OpenJDK 64-Bit Server VM Temurin-17.0.10+7 (build 17.0.10+7, mixed mode)

Which Docker images do I deploy?

  • I am a developer using a single-instance ForgeOps deployment.

    • UI elements. Deploy the supported images from ForgeRock.

    • Other platform elements. Either deploy:

      • The evaluation-only images from ForgeRock.

      • Docker images that are based on the evaluation-only images, but contain a customized configuration profile.

  • I am doing a proof-of-concept ForgeOps deployment.

    • UI elements. Deploy the supported images from ForgeRock.

    • Other platform elements. Either deploy:

      • The evaluation-only images from ForgeRock.

      • Docker images that are based on the evaluation-only images, but contain a customized configuration profile.

  • I am deploying the platform in production.

    • UI elements. Deploy the supported images from ForgeRock.

    • Other platform elements. Deploy Docker images that are based on your own base images, but contain a customized configuration profile. ForgeRock does not support production deployments with Docker images based on the evaluation-only images.

Your own base Docker images

Perform the following steps to build base images for the eight unsupported, evaluation-only Docker images. After you’ve built your own base images, push them to your Docker repository:

  1. Download the latest versions of the AM, Amster, IDM, and DS .zip files from the ForgeRock Download Center. Optionally, you can also download the latest version of the IG .zip file.

  2. If you haven’t already done so, clone the forgeops and forgeops-extras repositories. For example:

    $ git clone https://github.com/ForgeRock/forgeops.git
    $ git clone https://github.com/ForgeRock/forgeops-extras.git

    Both repositories are public; you do not need credentials to clone them.

  3. Check out the forgeops repository’s release/7.5-20240402 branch:

    $ cd /path/to/forgeops
    $ git checkout release/7.5-20240402
  4. Check out the forgeops-extras repository’s master branch:

    $ cd /path/to/forgeops-extras
    $ git checkout master
  5. Build the Java base image, which is required by several of the other Dockerfiles:

    $ cd /path/to/forgeops-extras/images/java-17
    $ docker build --tag my-repo/java-17 .

  12. Build the base image for IDM:

    1. Create a new shell script file named build-idm-image.sh and copy the following lines into it:

      #!/bin/bash
      
      if [ $# -lt 3 ]; then
        echo "$0 <source image> <new base image> <result image>"
        exit 0
      fi
      
      sourceImage="$1"
      javaImage="$2"
      resultImage="$3"
      
      container_id=$(docker create $sourceImage)
      docker export $container_id -o image.tar
      docker rm $container_id
      
      tar xvf image.tar opt/openidm
      rm -f image.tar
      
      cd opt/openidm
      # use | separators because image names often have / and :
      sed -i.bak 's|^FROM.*$|FROM '$javaImage'|' bin/Custom.Dockerfile
      rm bin/Custom.Dockerfile.bak
      
      docker build . --file bin/Custom.Dockerfile --tag "$resultImage"
      rm -rf opt
    2. Change the mode of the file to be executable and run it.

      $ chmod +x build-idm-image.sh
      $ ./build-idm-image.sh gcr.io/forgerock-io/idm-cdk:7.5.0 my-repo/java-17  my-repo/idm:7.5.0
      The build-idm-image.sh script expands the IDM Docker image, rebuilds the image, and cleans up afterward.
  13. (Optional) Build the base image for IG:

    1. Unzip the IG .zip file.

    2. Change to the identity-gateway directory in the expanded .zip file output.

    3. Edit the Dockerfile in the identity-gateway/docker directory. Change the line:

      FROM gcr.io/forgerock-io/java-17:latest

      to:

      FROM my-repo/java-17
    4. Build the ig base image:

  15. Push the new base Docker images to your Docker repository.

    Refer to your registry provider documentation for detailed instructions. For most Docker registries, you run the docker login command to log in to the registry. Then, you run the docker push command to push a Docker image to the registry.

    Be sure to configure your Docker registry so that you can successfully push your Docker images. Each cloud-based Docker registry has its own specific requirements. For example, on Amazon ECR, you must create a repository for each image.

    Push the following images to your repository:

    • my-repo/am:7.5.0

    • my-repo/am-config-upgrader:7.5.0

    • my-repo/amster:7.5.0

    • my-repo/ds-empty:7.5.0

    • my-repo/idm:7.5.0

    • my-repo/java-17

    If you’re deploying your own IG base image, also push the my-repo/ig:2024.3.0 image.

Create Docker images for use in production

After you’ve built and pushed your own base images to your Docker registry, you’re ready to build customized Docker images that can be used in a production deployment of the ForgeRock Identity Platform. These images:

Create your production-ready Docker images, create a Kubernetes cluster to test them, and delete the cluster when you’ve finished testing the images:

  1. Clone the forgeops repository.

  2. Obtain custom configuration profiles that you want to use in your Docker images from your developer, and copy them into your forgeops repository clone:

    • Obtain the AM configuration profile from the /path/to/forgeops/docker/am/config-profiles directory.

    • Obtain the IDM configuration profile from the /path/to/forgeops/docker/idm/config-profiles directory.

    • (Optional) Obtain the IG configuration profile from the /path/to/forgeops/docker/ig/config-profiles directory.

  3. Change the FROM lines of Dockerfiles in the forgeops repositories to refer to your own base Docker images:

    In the forgeops repository file: Change the FROM line to:

    docker/am/Dockerfile

    FROM my-repo/am:7.5.0 [1]

    docker/amster/Dockerfile

    FROM my-repo/amster:7.5.0

    docker/ds/ds-new/Dockerfile

    FROM my-repo/ds-empty:7.5.0

    docker/idm/Dockerfile

    FROM my-repo/idm:7.5.0 [2]

    (Optional) docker/ig/Dockerfile

    FROM my-repo/ig:2024.3.0

  4. If necessary, log in to your Docker registry.

  5. Build Docker images that are based on your own base images. The AM and IDM images contain your customized configuration profiles:

    $ cd /path/to/forgeops/bin
    $ ./forgeops build ds --push-to my-repo
    $ ./forgeops build amster --push-to my-repo
    $ ./forgeops build am --push-to my-repo --config-profile my-profile
    $ ./forgeops build idm --push-to my-repo --config-profile my-profile

    The forgeops build command:

    • Builds Docker images. The AM and IDM images incorporate customized configuration profiles.

    • Pushes Docker images to the repository specified in the --push-to argument.

    • Updates the image defaulter file, which the forgeops install command uses to determine which Docker images to run.

  6. (Optional) Build and push an IG Docker image that’s based on your own base image and contains your customized configuration profile:

    $ ./forgeops build ig --config-profile my-profile --push-to my-repo
  7. Prepare a Kubernetes cluster to test your images:

    1. Create the cluster. This example assumes that you create a cluster suitable for a small-sized ForgeOps deployment.

    2. Make sure your cluster can access and pull Docker images from your repository.

    3. Create a namespace in the new cluster, and then make the new namespace the active namespace in your local Kubernetes context.

  8. Perform a ForgeOps deployment in your cluster:

    $ ./forgeops install --small --fqdn forgeops.example.com
  9. Access the AM admin UI and the IDM admin UI, and verify that your customized configuration profiles are active.

  10. Delete the Kubernetes cluster that you used to test images.

At the end of this process, the artifacts that you’ll need to deploy the ForgeRock Identity Platform in production are available:

  • Docker images for the ForgeRock Identity Platform, in your Docker repository

  • An updated image defaulter file, in your forgeops repository clone

You’ll need to copy the image defaulter file to your production deployment, so that when you run the forgeops install command, it will use the correct Docker images.

Typically, you model the image creation process in a CI/CD pipeline. Then, you run the pipeline at milestones in the development of your customized configuration profile.
