OpenID Connect identity provider

Configure the oidc identity provider to integrate with an OpenID Connect identity provider using an Authorization Code Flow.

Prerequisites

  1. You created your account roles using Terraform.
  2. You created your cluster using Terraform. This cluster can either have a managed OIDC configuration or an unmanaged OIDC configuration.
  3. Optional: You have configured your Terraform.tfvars file.

Setting up OpenID Connect

For more information about OpenID connect authentication and configuration, see About OpenID Connect authentication.

Applying the Terraform plan

  1. You need to either create terraform.tfvars file in this directory or add the following items to your existing *.tfvars file. You may also export these variables as environmental variables with the following commands: variable "" { type = string description = "An RFC 2255 URL which specifies the LDAP search parameters to use." }

    1. This variable is a Boolean expression that allows you to decide if TLS connections to the server are allowed. The default value is false. 
      export TF_VAR_ldap_insecure=<true_or_false>
    2. This variable points to an RFC 2255 URL for your LDAP search parameters. 
      export TF_VAR_ldap_url=<URL_for_parameters>
    3. This variable should be your full OpenShift Cluster Manager offline token that you generated in the prerequisites. 
      export TF_VAR_token=<ocm_offline_token>
    4. This value should point to your OpenShift instance. 
      export TF_VAR_url=<ocm_url>
    5. The ID of the cluster for which you are creating the identity provider. This ID can be found in the rosa command-line interface (CLI) with the command rosa list cluster. 
      export TF_VAR_cluster_id=<cluster_id>
    6. Optional: This variable includes any additional trust certificate authority bundles. 
      export TF_VAR_ldap_ca=<trust-certificate-authority-bundle>

  2. In your local copy of the github folder, run the following command:

    terraform init

    Running this command accesses all the necessary provider information to apply your Terraform plan.

  3. Optional: Run the plan command to ensure that your Terraform files build correctly without errors. This is not required to apply your Terraform plan.

    terraform plan -out github.tfplan

  4. Run the apply command to create your GitHub identity provider.

    Note: If you did not run the plan command, you can simply just apply without specifying a file.

    terraform apply <"github.tfplan">

  5. The Terraform applies the plan and creates your identity provider using GitHub. You will see a prompt to confirm you want to create these resources. Enter yes, then the process will complete with your resources.

Resource clean up

After you are done with the resources you created, you should not delete them manually, but instead, use the destroy command. Run the following to delete all of your created resources:

terraform destroy

After the command is complete, your resources are deleted.

NOTE: If you manually delete a resource, you create unresolvable issues within your environment.
