1.3. Creating a ROSA cluster with AWS STS using the default auto mode
Red Hat OpenShift Cluster Manager is a managed service on the Red Hat Hybrid Cloud Console where you can install, modify, operate, and upgrade your Red Hat OpenShift clusters. This service allows you to work with all of your organization’s clusters from a single dashboard. The procedures in this document use the auto
modes in OpenShift Cluster Manager to immediately create the required Identity and Access Management (IAM) resources using the current AWS account. The required resources include the account-wide IAM roles and policies, cluster-specific Operator roles and policies, and OpenID Connect (OIDC) identity provider.
When using the OpenShift Cluster Manager Hybrid Cloud Console to create a Red Hat OpenShift Service on AWS (ROSA) cluster that uses the STS, you can select the default options to create the cluster quickly.
Before you can use the OpenShift Cluster Manager Hybrid Cloud Console to deploy ROSA with STS clusters, you must associate your AWS account with your Red Hat organization and create the required account-wide STS roles and policies.

Understanding AWS account association
Before you can use Red Hat OpenShift Cluster Manager on the Red Hat Hybrid Cloud Console to create Red Hat OpenShift Service on AWS (ROSA) clusters that use the AWS Security Token Service (STS), you must associate your AWS account with your Red Hat organization. You can associate your account by creating and linking the following IAM roles.
- OpenShift Cluster Manager role
Create an OpenShift Cluster Manager IAM role and link it to your Red Hat organization.
You can apply basic or administrative permissions to the OpenShift Cluster Manager role. The basic permissions enable cluster maintenance using OpenShift Cluster Manager. The administrative permissions enable automatic deployment of the cluster-specific Operator roles and the OpenID Connect (OIDC) provider using OpenShift Cluster Manager.
- User role
Create a user IAM role and link it to your Red Hat user account. The Red Hat user account must exist in the Red Hat organization that is linked to your OpenShift Cluster Manager role.
The user role is used by Red Hat to verify your AWS identity when you use the OpenShift Cluster Manager Hybrid Cloud Console to install a cluster and the required STS resources.
Associating your AWS account with your Red Hat organization
Before using Red Hat OpenShift Cluster Manager on the Red Hat Hybrid Cloud Console to create Red Hat OpenShift Service on AWS (ROSA) clusters that use the AWS Security Token Service (STS), create an OpenShift Cluster Manager IAM role and link it to your Red Hat organization. Then, create a user IAM role and link it to your Red Hat user account in the same Red Hat organization.
Procedure
Create an OpenShift Cluster Manager role and link it to your Red Hat organization:
NoteTo enable automatic deployment of the cluster-specific Operator roles and the OpenID Connect (OIDC) provider using the OpenShift Cluster Manager Hybrid Cloud Console, you must apply the administrative privileges to the role by choosing the Admin OCM role command in the Accounts and roles step of creating a ROSA cluster. For more information about the basic and administrative privileges for the OpenShift Cluster Manager role, see Understanding AWS account association.
NoteIf you choose the Basic OCM role command in the Accounts and roles step of creating a ROSA cluster in the OpenShift Cluster Manager Hybrid Cloud Console, you must deploy a ROSA cluster using manual mode. You will be prompted to configure the cluster-specific Operator roles and the OpenID Connect (OIDC) provider in a later step.
$ rosa create ocm-role
Select the default values at the prompts to quickly create and link the role.
Create a user role and link it to your Red Hat user account:
$ rosa create user-role
Select the default values at the prompts to quickly create and link the role.
NoteThe Red Hat user account must exist in the Red Hat organization that is linked to your OpenShift Cluster Manager role.
Creating the account-wide STS roles and policies
Before using the Red Hat OpenShift Cluster Manager Hybrid Cloud Console to create Red Hat OpenShift Service on AWS (ROSA) clusters that use the AWS Security Token Service (STS), create the required account-wide STS roles and policies, including the Operator policies.
Procedure
If they do not exist in your AWS account, create the required account-wide STS roles and policies:
$ rosa create account-roles
Select the default values at the prompts to quickly create the roles and policies.
Creating a cluster with the default options using OpenShift Cluster Manager
When using Red Hat OpenShift Cluster Manager on the Red Hat Hybrid Cloud Console to create a Red Hat OpenShift Service on AWS (ROSA) cluster that uses the AWS Security Token Service (STS), you can select the default options to create the cluster quickly. You can also use the admin OpenShift Cluster Manager IAM role to enable automatic deployment of the cluster-specific Operator roles and the OpenID Connect (OIDC) provider.
Procedure
- Navigate to OpenShift Cluster Manager and select Create cluster.
- On the Create an OpenShift cluster page, select Create cluster in the Red Hat OpenShift Service on AWS (ROSA) row.
Verify that your AWS account ID is listed in the Associated AWS accounts drop-down menu and that the installer, support, worker, and control plane account role Amazon Resource Names (ARNs) are listed on the Accounts and roles page.
NoteIf your AWS account ID is not listed, check that you have successfully associated your AWS account with your Red Hat organization. If your account role ARNs are not listed, check that the required account-wide STS roles exist in your AWS account.
- Click Next.
On the Cluster details page, provide a name for your cluster in the Cluster name field. Leave the default values in the remaining fields and click Next.
NoteCluster creation generates a domain prefix as a subdomain for your provisioned cluster on
openshiftapps.com
. If the cluster name is less than or equal to 15 characters, that name is used for the domain prefix. If the cluster name is longer than 15 characters, the domain prefix is randomly generated as a 15-character string. To customize the subdomain, select the Create custom domain prefix checkbox, and enter your domain prefix name in the Domain prefix field.- To deploy a cluster quickly, leave the default options in the Cluster settings, Networking, Cluster roles and policies, and Cluster updates pages and click Next on each page.
- On the Review your ROSA cluster page, review the summary of your selections and click Create cluster to start the installation.
Optional: On the Overview tab, you can enable the delete protection feature by selecting Enable, which is located directly under Delete Protection: Disabled. This will prevent your cluster from being deleted. To disable delete protection, select Disable. By default, clusters are created with the delete protection feature disabled.
Verification
You can check the progress of the installation in the Overview page for your cluster. You can view the installation logs on the same page. Your cluster is ready when the Status in the Details section of the page is listed as Ready.
NoteIf the installation fails or the cluster State does not change to Ready after about 40 minutes, check the installation troubleshooting documentation for details. For more information, see Troubleshooting installations. For steps to contact Red Hat Support for assistance, see Getting support for Red Hat OpenShift Service on AWS.
1.4. Creating a cluster administrator user for quick cluster access
Before configuring an identity provider, you can create a user with cluster-admin
privileges for immediate access to your Red Hat OpenShift Service on AWS (ROSA) cluster.
The cluster administrator user is useful when you need quick access to a newly deployed cluster. However, consider configuring an identity provider and granting cluster administrator privileges to the identity provider users as required. For more information about setting up an identity provider for your ROSA cluster, see Configuring an identity provider and granting cluster access.
Procedure
Create a cluster administrator user:
$ rosa create admin --cluster=<cluster_name> 1
- 1
- Replace
<cluster_name>
with the name of your cluster.
Example output
W: It is recommended to add an identity provider to login to this cluster. See 'rosa create idp --help' for more information. I: Admin account has been added to cluster '<cluster_name>'. I: Please securely store this generated password. If you lose this password you can delete and recreate the cluster admin user. I: To login, run the following command: oc login https://api.example-cluster.wxyz.p1.openshiftapps.com:6443 --username cluster-admin --password d7Rca-Ba4jy-YeXhs-WU42J I: It may take up to a minute for the account to become active.
NoteIt might take approximately one minute for the
cluster-admin
user to become active.

1.5. Configuring an identity provider and granting cluster access
Red Hat OpenShift Service on AWS (ROSA) includes a built-in OAuth server. After your ROSA cluster is created, you must configure OAuth to use an identity provider. You can then add members to your configured identity provider to grant them access to your cluster.
You can also grant the identity provider users with cluster-admin
or dedicated-admin
privileges as required.
Configuring an identity provider
You can configure different identity provider types for your Red Hat OpenShift Service on AWS (ROSA) cluster. Supported types include GitHub, GitHub Enterprise, GitLab, Google, LDAP, OpenID Connect and htpasswd identity providers.
The htpasswd identity provider option is included only to enable the creation of a single, static administration user. htpasswd is not supported as a general-use identity provider for Red Hat OpenShift Service on AWS.
The following procedure configures a GitHub identity provider as an example.
Procedure
- Go to github.com and log in to your GitHub account.
- If you do not have an existing GitHub organization to use for identity provisioning for your ROSA cluster, create one. Follow the steps in the GitHub documentation.
Configure a GitHub identity provider for your cluster that is restricted to the members of your GitHub organization.
Configure an identity provider using the interactive mode:
$ rosa create idp --cluster=<cluster_name> --interactive 1
- 1
- Replace
<cluster_name>
with the name of your cluster.
Example output
I: Interactive mode enabled. Any optional fields can be left empty and a default will be selected. ? Type of identity provider: github ? Identity provider name: github-1 ? Restrict to members of: organizations ? GitHub organizations: <github_org_name> 1 ? To use GitHub as an identity provider, you must first register the application: - Open the following URL: https://github.com/organizations/<github_org_name>/settings/applications/new?oauth_application%5Bcallback_url%5D=https%3A%2F%2Foauth-openshift.apps.<cluster_name>/<random_string>.p1.openshiftapps.com%2Foauth2callback%2Fgithub-1&oauth_application%5Bname%5D=<cluster_name>&oauth_application%5Burl%5D=https%3A%2F%2Fconsole-openshift-console.apps.<cluster_name>/<random_string>.p1.openshiftapps.com - Click on 'Register application' ...
- 1
- Replace
<github_org_name>
with the name of your GitHub organization.
Follow the URL in the output and select Register application to register a new OAuth application in your GitHub organization. By registering the application, you enable the OAuth server that is built into ROSA to authenticate members of your GitHub organization into your cluster.
NoteThe fields in the Register a new OAuth application GitHub form are automatically filled with the required values through the URL defined by the ROSA CLI.
Use the information from your GitHub OAuth application page to populate the remaining
rosa create idp
interactive prompts.Continued example output
... ? Client ID: <github_client_id> 1 ? Client Secret: [? for help] <github_client_secret> 2 ? GitHub Enterprise Hostname (optional): ? Mapping method: claim 3 I: Configuring IDP for cluster '<cluster_name>' I: Identity Provider 'github-1' has been created. It will take up to 1 minute for this configuration to be enabled. To add cluster administrators, see 'rosa grant user --help'. To login into the console, open https://console-openshift-console.apps.<cluster_name>.<random_string>.p1.openshiftapps.com and click on github-1.
NoteIt might take approximately two minutes for the identity provider configuration to become active. If you have configured a
cluster-admin
user, you can watch the OAuth pods redeploy with the updated configuration by runningoc get pods -n openshift-authentication --watch
.Enter the following command to verify that the identity provider has been configured correctly:
$ rosa list idps --cluster=<cluster_name>
Example output
NAME TYPE AUTH URL github-1 GitHub https://oauth-openshift.apps.<cluster_name>.<random_string>.p1.openshiftapps.com/oauth2callback/github-1
Additional resource
- For detailed steps to configure each of the supported identity provider types, see Configuring identity providers for STS.
Granting user access to a cluster
You can grant a user access to your Red Hat OpenShift Service on AWS (ROSA) cluster by adding them to your configured identity provider.
You can configure different types of identity providers for your ROSA cluster. The following example procedure adds a user to a GitHub organization that is configured for identity provision to the cluster.
Procedure
- Navigate to github.com and log in to your GitHub account.
- Invite users that require access to the ROSA cluster to your GitHub organization. Follow the steps in Inviting users to join your organization in the GitHub documentation.
Granting administrator privileges to a user
After you have added a user to your configured identity provider, you can grant the user cluster-admin
or dedicated-admin
privileges for your Red Hat OpenShift Service on AWS (ROSA) cluster.
Procedure
To configure
cluster-admin
privileges for an identity provider user:Grant the user
cluster-admin
privileges:$ rosa grant user cluster-admin --user=<idp_user_name> --cluster=<cluster_name> 1
- 1
- Replace
<idp_user_name>
and<cluster_name>
with the name of the identity provider user and your cluster name.
Example output
I: Granted role 'cluster-admins' to user '<idp_user_name>' on cluster '<cluster_name>'
Verify if the user is listed as a member of the
cluster-admins
group:$ rosa list users --cluster=<cluster_name>
Example output
ID GROUPS <idp_user_name> cluster-admins
To configure
dedicated-admin
privileges for an identity provider user:Grant the user
dedicated-admin
privileges:$ rosa grant user dedicated-admin --user=<idp_user_name> --cluster=<cluster_name>
Example output
I: Granted role 'dedicated-admins' to user '<idp_user_name>' on cluster '<cluster_name>'

1.9. Deleting a ROSA cluster and the AWS STS resources
You can delete a ROSA cluster that uses the AWS Security Token Service (STS) by using the Red Hat OpenShift Service on AWS (ROSA) CLI, rosa
. You can also use the ROSA CLI to delete the AWS Identity and Access Management (IAM) account-wide roles, the cluster-specific Operator roles, and the OpenID Connect (OIDC) provider. To delete the account-wide inline and Operator policies, you can use the AWS IAM Console.
Account-wide IAM roles and policies might be used by other ROSA clusters in the same AWS account. You must only remove the resources if they are not required by other clusters.
Procedure
Delete a cluster and watch the logs, replacing
<cluster_name>
with the name or ID of your cluster:$ rosa delete cluster --cluster=<cluster_name> --watch
ImportantYou must wait for the cluster deletion to complete before you remove the IAM roles, policies, and OIDC provider. The account-wide roles are required to delete the resources created by the installer. The cluster-specific Operator roles are required to clean-up the resources created by the OpenShift Operators. The Operators use the OIDC provider to authenticate.
Delete the OIDC provider that the cluster Operators use to authenticate:
$ rosa delete oidc-provider -c <cluster_id> --mode auto 1
- 1
- Replace
<cluster_id>
with the ID of the cluster.
NoteYou can use the
