CDK architecture
You deploy the CDK to get the ForgeRock Identity Platform up and running on Kubernetes. CDK deployments are useful for demonstrations and proofs of concept. They’re also intended for development—building custom Docker images for the platform.
Do not use the CDK as the basis for a production deployment of the ForgeRock Identity Platform. |
Before you can deploy the CDK, you must have:
-
Access to a Kubernetes cluster with the NGINX ingress controller deployed on it.
-
Access to a namespace in the cluster.
-
Third-party software installed in your local environment, as described in the Setup section that pertains to your cluster type.
This diagram shows the CDK components:
The forgeops install command deploys the CDK in a Kubernetes cluster:
-
Installs Docker images for the platform specified in the image defaulter. Initially, the image defaulter specifies the evaluation-only Docker images for release 7.4.0 of the platform, available from ForgeRock’s public registry. These images use ForgeRock’s canonical configurations for AM and IDM.
-
Installs additional software as needed[1]:
After you’ve deployed the CDK, you can access AM and IDM UIs and REST APIs to customize the ForgeRock Identity Platform’s configuration. You can then create Docker images that contain your customized configuration by using the forgeops build command. This command:
-
Builds Kubernetes manifests based on the Kustomize bases and overlays in your local
forgeops
repository clone. -
Updates the image defaulter file to specify the customized images, so that the next time you deploy the CDK, your customized images will be used.
CDK pods
After deploying the CDK, the following pods run in your namespace:
am
-
Runs ForgeRock Access Management.
When AM starts in a CDK deployment, it obtains its configuration from the AM Docker image specified in the image defaulter.
After the
am
pod has started, a job is triggered that populates AM’s application store with several agents and OAuth 2.0 client definitions that are used by the CDK. ds-idrepo-0
-
The
ds-idrepo-0
pod provides directory services for:-
The identity repository shared by AM and IDM
-
The IDM repository
-
The AM application and policy store
-
AM’s Core Token Service
-
idm
-
Runs ForgeRock Identity Management.
When IDM starts in a CDK deployment, it obtains its configuration from the IDM Docker image specified in the image defaulter.
In containerized deployments, IDM must retrieve its configuration from the file system and not from the IDM repository. The default values for the
openidm.fileinstall.enabled
andopenidm.config.repo.enabled
properties in the CDK’s system.properties file ensure that IDM retrieves its configuration from the file system. Do not override the default values for these properties. - UI pods
-
Several pods provide access to ForgeRock common user interfaces:
-
admin-ui
-
end-user-ui
-
login-ui
-
