Quick introduction to deployment on Minishift for new users and readers evaluating the software.

Preface

The Getting Started on Minishift guide provides instructions for quickly installing AM and IDM on a Minishift environment.

This guide covers the tasks you need to quickly get the AM and IDM on a Minishift environment.

Before You Begin

Before deploying the ForgeRock Identity Platform in a DevOps environment, read the important information in Start Here.

About ForgeRock Identity Platform Software

ForgeRock Identity Platform™ serves as the basis for our simple and comprehensive Identity and Access Management solution. We help our customers deepen their relationships with their customers, and improve the productivity and connectivity of their employees and partners. For more information about ForgeRock and about the platform, see https://www.forgerock.com.

The platform includes the following components:

Chapter 1. Introducing ForgeRock Identity Platform on Minishift

Minishift is a single-node OpenShift cluster environment running in a local virtual machine.

This Getting Started on Minishift guide provides instructions for quickly deploying and running the ForgeRock Identity Platform on a Minishift environment.

1.1. About the Example Deployment

The example deployment presented in this guide lets you get a simple ForgeRock Identity Platform deployment up and running in Minishift as quickly as possible. The deployment uses a minimally viable configuration for AM and IDM. This minimal configuration is suitable for evaluation and demonstration purposes only.

This section describes several characteristics of the example deployment, and provides resources you can use for more complex deployments.

1.1.1. ForgeRock Identity Platform Configuration

The example deployment configures ForgeRock Identity Platform components as simply as possible:

  • AM's configuration is empty: no realms, service configurations, or policies are configured in addition to the default configuration.

  • IDM's configuration implements bidirectional data synchronization between IDM and LDAP described in Synchronizing Data Between LDAP and IDM in the Samples Guide.

1.1.2. Secure Communication With ForgeRock Identity Platform Services

The example deployment provides secure access over HTTPS to ForgeRock Identity Platform server web UIs and REST APIs.

See "Configuring and Installing the frconfig Helm Chart" in the DevOps Developer's Guide for more information about securing communication to ForgeRock Identity Platform servers.

1.1.3. Runtime Changes to the AM Web Application

The example deployment installs the default AM .war file. You can customize this .war file to provide enhancements such as custom authentication modules, cross-origin resource sharing (CORS) support, or a custom look and feel for web UIs.

See "Customizing the AM Web Application" in the DevOps Developer's Guide for details about customizing the AM .war file when running in a DevOps environment.

Chapter 2. Setting Up the Deployment Environment

This chapter describes how to set up your Minishift environment to deploy AM and IDM.

The chapter covers the following topics:

2.1. Installing Required Third-Party Software

Before installing the AM and IDM, review "Installing Required Third-Party Software" in the DevOps Release Notes to determine which software you need. Then install the required software on your local computer.

2.2. Cloning the forgeops Repository

Before you can deploy the AM environment, you must clone the forgeops repository. Follow the instructions in "forgeops Repository" in the DevOps Release Notes.

To Obtain the forgeops Repository

The forgeops repository is a public Git repository. You do not need credentials to clone it:

  1. Clone the forgeops repository:

    $ git clone https://github.com/ForgeRock/forgeops.git
  2. Check out the release/6.5.2 branch:

    $ cd forgeops
    $ git checkout release/6.5.2

2.3. Initiating Minishift

This section describes how to start up Minishift and enable appropriate security context constraints (SCCs). SCCs allow administrators to control permissions for pods.

To Set Up Minishift
  1. Start your Minishift instance:

    $ minishift start
  2. Enable the anyuid policy. This policy allows pods to run as the forgerock user, instead of a random user id generated by Minishift:

    $ minishift addons enable anyuid
  3. Log in to Minishift as the system user and get the available SCCs:

    $ oc login -u system:admin
    $ oc get scc
  4. Log back in to Minishift as the normal user:

    $ oc login -u developer -p password
    

Chapter 3. Deploying AM and IDM

This chapter describes how to deploy AM and IDM in a Minishift environment.

This chapter covers the following topics:

3.1. Deploying Access Management

Perform the following procedure to install, configure, and start AM:

To Deploy Access Management
  1. Change to the Helm charts directory in your forgeops repository clone:

    $ cd /path/to/forgeops/helm
  2. Deploy the frconfig Helm chart:

    $ helm template frconfig | oc apply -f -
  3. Deploy the configuration store:

    $ helm template --set instance=configstore ds | oc apply -f -
  4. Deploy the user store:

    $ helm template --set instance=userstore ds | oc apply -f -
  5. Deploy Amster:

    $ helm template amster | oc apply -f -
  6. Deploy AM:

    $ helm template openam | oc apply -f -

After completing the "To Deploy Access Management" procedure, AM is deployed in the myproject namespace of Minishift.

3.2. Creating Routes

A route is the Minishift equivalent of a Kubernetes ingress. Create routes that let users access the AM console, the IDM user interface, and the IDM admin console.

To Create Routes
  1. Access the Minishift console:

    $ minishift console
  2. Note the Minishift IP address, for example: 192.168.99.102.

  3. Add host entries to your /etc/hosts file.

    For example:

    192.168.99.102 openam login.myproject.iam.example.com myproject.iam.example.com 
  4. In the Minishift console, create three routes to provide access to AM and IDM UIs:

    1. Create a route to the AM console with these parameters:

      • Hostname: login.myproject.iam.example.com

      • Path: /

      • Target port: 80

      • Secure route: (Selected)

      • TLS Termination: Edge

    2. Create a route to the IDM user interface with these parameters:

      • Hostname: myproject.iam.example.com

      • Path: openidm

      • Target port: 80

      • Secure route: (Selected)

      • TLS Termination: Edge

    3. Create a route to the IDM console with these parameters:

      • Hostname: myproject.iam.example.com

      • Path: /admin

      • Target port: 80

      • Secure route: (Selected)

      • TLS Termination: Edge

3.3. Verifying AM Access

Access the URL https://login.myproject.iam.example.com/ in your browser to verify that you can access AM user interface.

If you are redirected to http://openam, then perform these steps:

  1. Create a route for http://openam/ in Minishift using the steps in the "To Create Routes" procedure.

  2. Access the AM administration console, and update the Fixed value base URL parameter value to https://myproject.iam.example.com.

  3. Save the changes and restart the AM pod using the kubectl command:

    $ kubectl delete pod openam-pod

3.4. Deploying Identity Management

The example IDM deployment in Minishift uses Postgres to store data. Because of this, you'll need to deploy the postgres-openidm Helm chart before you deploy the openidm Helm chart.

To Deploy IDM
  1. Deploy Postgres:

    $ helm template postgres-openidm | oc apply -f -
  2. Deploy IDM:

    $ helm template openidm | oc apply -f -

3.5. Verifying IDM Access

Access the URL https://myproject.iam.example.com/admin#login/ in your browser to verify that you can access the IDM console.

Glossary

affinity (AM)

AM affinity based load balancing ensures that the CTS token creation load is spread over multiple server instances (the token origin servers). Once a CTS token is created and assigned to a session, all subsequent token operations are sent to the same token origin server from any AM node. This ensures that the load of CTS token management is spread across directory servers.

Source: Best practices for using Core Token Service (CTS) Affinity based load balancing in AM

Amazon EKS

Amazon Elastic Container Service for Kubernetes (Amazon EKS) is a managed service that makes it easy for you to run Kubernetes on Amazon Web Services without needing to set up or maintain your own Kubernetes control plane.

Source: What is Amazon EKS in the Amazon EKS documentation.

ARN (AWS)

An Amazon Resource Name (ARN) uniquely identifies an Amazon Web Service (AWS) resource. AWS requires an ARN when you need to specify a resource unambiguously across all of AWS, such as in IAM policies and API calls.

Source: Amazon Resource Names (ARNs) and AWS Service Namespaces in the AWS documentation.

AWS IAM Authenticator for Kubernetes

The AWS IAM Authenticator for Kubernetes is an authentication tool that enables you to use Amazon Web Services (AWS) credentials for authenticating to a Kubernetes cluster.

cluster

A container cluster is the foundation of Kubernetes Engine. A cluster consists of at least one cluster master and multiple worker machines called nodes. The Kubernetes objects that represent your containerized applications all run on top of a cluster.

Source: Container Cluster Architecture in the Kubernetes Concepts documentation.

cluster master

A cluster master schedules, runs, scales and upgrades the workloads on all nodes of the cluster. The cluster master also manages network and storage resources for workloads.

Source: Container Cluster Architecture in the Kubernetes Concepts docuementation.

ConfigMap

A configuration map, called ConfigMap in Kubernetes manifests, binds the configuration files, command-line arguments, environment variables, port numbers, and other configuration artifacts to the assigned containers and system components at runtime. The configuration maps are useful for storing and sharing non-sensitive, unencrypted configuration information.

Source: ConfigMap in the Kubernetes Cocenpts documentation.

container

A container is an allocation of resources such as CPU, network I/O, bandwidth, block I/O, and memory that can be “contained” together and made available to specific processes without interference from the rest of the system.

Source Container Cluster Architecture in the Google Cloud Platform documentation

DaemonSet

A set of daemons, called DaemonSet in Kubernetes manifests, manages a group of replicated pods. Usually, the daemon set follows an one-pod-per-node model. As you add nodes to a node pool, the daemon set automatically distributes the pod workload to the new nodes as needed.

Source DaemonSet in the Google Cloud Platform documentation.

Deployment

A Kubernetes deployment represents a set of multiple, identical pods. A Kubernetes deployment runs multiple replicas of your application and automatically replaces any instances that fail or become unresponsive.

Source: Deployment in the Google Cloud Platform documentation.

deployment controller

A deployment controller provides declarative updates for pods and replica sets. You describe a desired state in a deployment object, and the deployment controller changes the actual state to the desired state at a controlled rate. You can define deployments to create new replica sets, or to remove existing deployments and adopt all their resources with new deployments.

Source: Deployments in the Google Cloud Platform documentation.

Docker Cloud

Docker Cloud provides a hosted registry service with build and testing facilities for Dockerized application images; tools to help you set up and manage host infrastructure; and application lifecycle features to automate deploying (and redeploying) services created from images.

Source: About Docker Cloud in the Docker Cloud documentation.

Docker container

A Docker container is a runtime instance of a Docker image. A Docker container is isolated from other containers and its host machine. You can control how isolated your container’s network, storage, or other underlying subsystems are from other containers or from the host machine.

Source: Containers section in the Docker architecture documentation.

Docker daemon

The Docker daemon (dockerd) listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes. A Docker daemon can also communicate with other Docker daemons to manage Docker services.

Source: Docker daemon section in the Docker Overview documentation.

Docker Engine

The Docker Engine is a client-server application with these components:

  • A server, which is a type of long-running program called a daemon process (the dockerd command)

  • A REST API, which specifies interfaces that programs can use to talk to the daemon and tell it what to do

  • A command-line interface (CLI) client (the docker command)

Source: Docker Engine section in the Docker Overview documentation.

Dockerfile

A Dockerfile is a text file that contains the instructions for building a Docker image. Docker uses the Dockerfile to automate the process of building a Docker image.

Source: Dockerfile section in the Docker Overview documentation.

Docker Hub

Docker Hub provides a place for you and your team to build and ship Docker images. You can create public repositories that can be accessed by any other Docker Hub user, or you can create private repositories you can control access to.

An image is an application you would like to run. A container is a running instance of an image.

Source: Overview of Docker Hub section in the Docker Overview documentation.

Docker image

A Docker image is a read-only template with instructions for creating a Docker container. Often, an image is based on another image, with some additional customization.

A Docker image includes the application code, a runtime engine, libraries, environment variables, and configuration files that are required to run the application.

An image is an application you would like to run. A container is a running instance of an image.

Source: Docker objects section in the Docker Overview documentation. Hello Whales: Images vs. Containers in Dockers.

Docker namespace

Docker namespaces provide a layer of isolation. When you run a container, Docker creates a set of namespaces for that container. Each aspect of a container runs in a separate namespace and its access is limited to that namespace.

The PID namespace is the mechanism for remapping process IDs inside the container. Other namespaces such as net, mnt, ipc, and uts provide the isolated environments we know as containers. The user namespace is the mechanism for remapping user IDs inside a container.

Source: Namespaces section in the Docker Overview documentation.

Docker registry

A Docker registry stores Docker images. Docker Hub and Docker Cloud are public registries that anyone can use, and Docker is configured to look for images on Docker Hub by default. You can also run your own private registry.

Source: Docker registries section in the Docker Overview documentation.

Docker repository

A Docker repository is a public, certified repository from vendors and contributors to Docker. It contains Docker images that you can use as the foundation to build your applications and services.

Source: Repositories on Docker Hub section in the Docker Overview documentation.

Docker service

In a distributed application, different pieces of the application are called “services.” Docker services are really just “containers in production.” A Docker service runs only one image, but it codifies the way that image runs including which ports to use, the number replicas the container should run, and so on. By default, the services are load-balanced across all worker nodes.

Source: About services in the Docker Get Started documentation.

dynamic volume provisioning

The process of creating storage volumes on demand is called dynamic volume provisioning. Dynamic volume provisioning allows storage volumes to be created on-demand. It automatically provisions storage when it is requested by users.

Source: Dynamic Volume Provisioning in the Kubernetes Concepts documentation.

egress

An egress controls access to destinations outside the network from within a Kubernetes network. For an external destination to be accessed from a Kubernetes environment, the destination should be listed as an allowed destination in the whitelist configuration.

Source: Network Policies in the Kubernetes Concepts documentation.

firewall rule

A firewall rule lets you allow or deny traffic to and from your virtual machine instances based on a configuration you specify. Each Kubernetes network has a set of firewall rules controlling access to and from instances in its subnets. Each firewall rule is defined to apply to either incoming glossary-ingress(ingress) or outgoing (egress) traffic, not both.

Source: Firewall Rules Overview in the Google Cloud Platform documentation.

garbage collection

Garbage collection is the process of deleting unused objects. Kubelets perform garbage collection for containers every minute and garbage collection for images every five minutes. You can adjust the high and low threshold flags and garbage collection policy to tune image garbage collection.

Source: Garbage Collection in the Kubernetes Concepts documentation.

node controller (Kubernetes)

A Kubernetes node controller is a Kubernetes master component that manages various aspects of the nodes such as: lifecycle operations on the nodes, operational status of the nodes, and maintaining an internal list of nodes.

Source: Node Controller in the Kubernetes Concepts documentation.

persistent volume

A persistent volume (PV) is a piece of storage in the cluster that has been provisioned by an administrator. It is a resource in the cluster just like a node is a cluster resource. PVs are volume plugins that have a lifecycle independent of any individual pod that uses the PV.

Source: Persistent Volumes in the Kubernetes Concepts documentation.

persistent volume claim

A persistent volume claim (PVC) is a request for storage by a user. A PVC specifies size, and access modes such as:

  • Mounted once for read and write access

  • Mounted many times for read-only access

Source: Persistent Volumes in the Kubernetes Concepts documentation.

pod anti-affinity (Kubernetes)

Kubernetes pod anti-affinity allows you to constrain which nodes can run your pod, based on labels on the pods that are already running on the node rather than based on labels on nodes. Pod anti-affinity enables you to control the spread of workload across nodes and also isolate failures to nodes.

shard

Sharding is a way of partitioning directory data so that the load can be shared by multiple directory servers. Each data partition, also known as a shard, exposes the same set of naming contexts, but only a subset of the data. For example, a distribution might have two shards. The first shard contains all users whose name begins with A-M, and the second contains all users whose name begins with N-Z. Both have the same naming context.

Source: Class Partition in the OpenDJ Javadoc.

stack (AWS)

A stack is a collection of AWS resources that you can manage as a single unit. You can create, update, or delete a collection of resources by using stacks. All the resources in a stack are defined by the template.

Source: Working with Stacks in the AWS documentation.

stack set (AWS)

A stack set is a container for stacks. You can provision stacks across AWS accounts and regions by using a single AWS template. All the resources included in each stack of a stack set are defined by the same template.

Source: StackSets Concepts in the AWS documentation.

volume (Kubernetes)

A Kubernetes volume is a storage volume that has the same lifetime as the pod that encloses it. Consequently, a volume outlives any containers that run within the pod, and data is preserved across container restarts. When a pod ceases to exist, the Kubernetes volume also ceases to exist.
