Configuring IBM Cloud Pak foundational services

This version of documentation is no longer updated. For the latest information, see the following links:
- Continuous Delivery (CD) documentation
- Support Cycle-2 (SC-2) documentation

The IBM Cloud Pak foundational services operator creates the CommonService custom resource (CR) in the common service operator namespace.

The custom resource has the services, cluster configurations, and hardware profile that you can set before or after you install foundational services.

You can access the CommonService custom resource by using the OpenShift Container Platform console or by using the command-line interface (CLI).

oc edit CommonService common-service -n <your-foundational-services-namespace>

Note: The common-service CR in the common service operator namespace is the only CR that is used for updating and configuring foundational services. There can be other CRs in the operand namespace. However, the other CRs are managed by other services and should not be edited.

For example, by running the following command you get two similar CRs in the response. Only common-service CR oversees IBM Cloud Pak foundational services configuration:

   oc get commonservice -A

The response:

   NAMESPACE   NAME                AGE
   cp4itest    common-service      172d  << Only this CR needs to be edited.
   cp4itest    im-common-service   144d

Troubleshooting: If the changes to the common-service CR get reverted by an IBM Cloud Pak's operator, create a new common service CR, for example, CS-custom-IM-resource CR, with the desired change. For more information, see Customization of the CommonService CR is reverted by the IBM Cloud Pak operator.

Parameters in the CommonService CR

The CommonService CR has some parameters that control the placement of the OperandRegistry and OperandConfig in various deployment topologies. For more information about the topologies, see Topologies that need the IBM NamespaceScope Operator.

Updating the custom resource

Set the following parameters by adding them to the CommonService custom resource. You can update these parameters before you create an OperandRequest instance or after you install the services. Add or modify the parameters and values in the spec section.

Approval strategy

The approval strategy defines whether the approval is needed to install, or upgrade IBM Cloud Pak foundational services. By default, the approval strategy is set to Automatic, however, you can change this setting during installation. You can also set the approval strategy after the installation by adding or changing the installPlanApproval parameter in the custom resource. If the approval strategy is set to Automatic, the operator is automatically installed or upgraded when a new version is available. If you set the installPlanApproval parameter to Manual, the operator is not automatically installed or upgraded. Instead, you get an an install plan that needs to be manually approved before an upgrade.

Notes:

Changing approval strategy from Automatic to Manual

To change the approval strategy from Automatic to Manual, change the installPlanApproval parameter value to Manual in the spec section of the CommonService CR.

Note: If the installPlanApproval parameter is not in the CR, add the following line to the CR in the spec section: installPlanApproval: Manual.

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  installPlanApproval: Manual

Changing approval strategy from Manual to Automatic

Note: Before you begin, make sure that the operators that are not a part of IBM Cloud Pak foundational services in the namespace have the installPlanApproval parameter set to Automatic in the subscription. Otherwise, even if you change the approval strategy from Manual to Automatic for the IBM Cloud Pak foundational services operator, this setting might be overwritten.

To change the approval strategy from Manual to Automatic, complete the following steps:

  1. Change the installPlanApproval parameter value to Automatic in the spec section of the CommonService CR.

Note: If the installPlanApproval parameter is not in the CR, add the following line to the CR in the spec section: installPlanApproval: Automatic.

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  installPlanApproval: Automatic

Bring your own CA Certificate

You can replace the foundational services self-signed certificate authority (CA) certificate with your own CA certificate in either of the following ways:

Note: Anytime you need to bring back your original certificate, see Bringing back your original CA Certificate.

If you are updating the CommonService CR to bring your own certificate, first update BYOCACertificate: true in the spec section of the CommonService CR.

Note: If BYOCACertificate specification is not in the CR, you can add it in the spec section as shown in the following example:

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  BYOCACertificate: true

After you update the CommonService CR, complete the following steps to replace the foundational services self-signed CA certificate with your own CA certificate:

  1. Prepare and have your Transport Layer Security (TLS) certificate, TLS private key, and CA certificate ready.

  2. Create a backup of the foundational services self-signed CA certificate. By default, the certificate is created in the foundational-services namespace.

     oc get certificate cs-ca-certificate -n <your-foundational-services-namespace> -o yaml > cs-ca-certificate.yaml

  3. Delete the foundational services self-signed CA certificate resource so that the cert-manager service does not re-create the updated secret.

     oc delete certificate cs-ca-certificate -n <your-foundational-services-namespace>

  4. Delete the foundational services self-signed CA certificate secret.

     oc delete secret cs-ca-certificate-secret -n <your-foundational-services-namespace>

  5. Re-create the cs-ca-certificate-secret secret with your CA certificate (ca.crt), TLS certificate (tls.crt), and private key (tls.key).

     oc -n <your-foundational-services-namespace> create secret generic cs-ca-certificate-secret --from-file=ca.crt=<your path>/ca.crt  --from-file=tls.crt=<your path>/tls.crt  --from-file=tls.key=<your path>/tls.key

  6. Refresh the leaf certificates that are created by individual foundational services. For more information and steps to refresh the leaf certificates, see Refreshing cert-manager certificates.

Configuring custom EDB operator

You can configure custom EDB operator for the foundational services such as IM or Zen. For more information, see Configuring custom EDB operator.

License

Note: To enable IBM Support, you must accept the license. For more information about Licensing acceptance, see License Accept.

Accept the licenses to use the services. To do so, add spec.license.accept: true in the spec section of the CRs. See the following samples:

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  license:
    accept: true
  size: as-is

apiVersion: operator.ibm.com/v1alpha1
kind: IBMLicensing
metadata:
  name: instance
spec:
  license:
    accept: true

apiVersion: operator.ibm.com/v1
kind: CertManagerConfig
metadata:
  name: default
spec:
  license:
    accept: true

apiVersion: operator.ibm.com/v1
kind: NamespaceScope
metadata:
  name: common-service
  namespace: <foundational-services-namespace>
spec:
  license:
    accept: true

Hardware profile

Set the hardware requirements profile based on the workloads in your cluster. For more information about the profiles, see Hardware requirements and recommendations for foundational services.

You can use the templates to update the hardware requirements of the services that you are installing. You can also use the templates to set the configuration parameters of the services.

The default profile is starterset (starter). You can change the profile to small, medium, or large (production), if required. If you are upgrading your cluster from a previous release, the default profile setting is as-is, which means that the hardware requirements setting from the previous release is retained.

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  size: as-is

Storage class

Instead of specifying the storage class for each service in the spec.<service-name> section, you can specify a storage class for all services in the spec section. Any service that needs to use a storage class will then use this specified storage class.

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  size: as-is
  storageClass: <storage-class-name>

When you specify a storage class in the spec section, the storage class of a service is updated to reflect this value only if the service is not yet deployed.

For more information about configuring options that are related to storage for PostgreSQL common-service-db services, see Cloud Native PostgreSQL settings.

Services configuration

Add any service-related configuration in the spec.services section. First, add services: under spec:. You need to add services: section only once. You can add all services-related configuration under the same section.

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  services:

Then, add the service configuration. For example, if you are adding a storage class for common-service-db, the configuration would be as shown in the following example:

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  services:
  - name: common-service-db
    spec:
      storage:
        storageClass: <your-storage-class>
      walStorage:
        storageClass: <your-storage-class>

Example: Modifying the resources for IM service pod

  1. Run the following command you retrieve the operand configuration for the IM service.
oc get operandconfig common-service -n <common service operand namespace> -oyaml | grep ibm-im-operator -A40 -m

The response:

- name: ibm-im-operator
  spec
    authentication:
      authService:
        resources:
          limits:
            cpu: 1000m
            memory: 1090Mi
          requests:
            cpu: 600m
            ephemeral-storage: 256Mi
            memory: 540Mi
  ---
  1. Copy the part of the response with the appropriate section from the operandConfig and add this part to the common-service CR. Run the following command to edit the common-service CR:
oc edit commonservice common-service -n <common service operator namespace>
  1. Edit the common-service CR by pasting the block from the response into the CR and modify the resource limits and requests for IAM.

Note: If this is the first time when you add a part of the operandConfig yaml into the common-service CR, you need to precede the block with the services section. It is important to keep the columns exactly as copied from the operandConfig to keep the column-sensitive yaml formatting.

spec:
  license:
    accept: true
  operatorNamespace: cp4itest
  size: medium
  services:                             <<<  Add the services section before the block from the operandConfig when you add your first configuration
  - name: ibm-im-operator
    spec:
      authentication:
        authService:
          resources:
            limits:
              cpu: 1000m
              memory: 1090Mi
            requests:
              cpu: 700m
              ephemeral-storage: 256Mi
              memory: 540Mi

Add Labels to foundational services resources

Add labels to all foundational services resources including IM and IDP Config UI

Specify the labels that you want to add to all foundational services resources in the spec section of the CommonService CR. The labels are added to all the resources that are created by the foundational services.

The labels are added to all the resources that are created by the License service reporter. See Managing License Service Reporter metadata for more information.

Federal Information Processing Standard (FIPS)

For information on configuring foundational services to enable FIPS, see Enabling FIPS.

Ephemeral storage setting

Huge pages settings

To enable huge pages for foundational services, you must configure the huge pages setting in Red Hat® OpenShift® Container Platform first. For more information, about configuring huge pages on Red Hat OpenShift Container Platform, see What huge pages do and how they are consumed by applications.

You can configure huge pages settings for Identity Management (IM) and its dependency Cloud Native PostgreSQL by modifying the foundational services Custom Resource and specifying huge pages allocation in the spec section.

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: huge-pages-common-service
spec:
  size: small
  hugepages:           
     enable: true
     hugepages-<size>: <allocation>

To view which services support huge pages and how to enable this setting, see Configuring huge pages for foundational services.

Cloud Native PostgreSQL settings

Storage class and Volume Size (common-service-postgresql)

Specify a storage class name for the persistent volume. If you do not add the storage class configuration, the default storage class that is available in the cluster is used for PostgreSQL Cluster CR.

services:
  - name: common-service-postgresql
    spec: {}
    resources:
      - apiVersion: postgresql.k8s.enterprisedb.io/v1
        kind: Cluster
        name: common-service-db
        data:
          spec:
            storage:
              storageClass: <your-storage-class>
              size: <volume-size>
            walStorage:
              storageClass: <your-storage-class>
              size: <volume-size>

Notes:

Configuring resources for PostgreSQL cluster (common-service-postgresql)

Specify resource settings. If you do not specify a setting, the default resource settings that are available in the cluster are used for PostgreSQL cluster.

services:
  - name: common-service-postgresql
    spec: {}
    resources:
      - apiVersion: postgresql.k8s.enterprisedb.io/v1
        kind: Cluster
        name: common-service-db
        data:
          spec:
            instances: 3 
            resources:
              limits: 
                cpu: <cpu-limit>
                memory: <memory-limit>
                ephemeralStorage: <ephemeral-storage-limit>
                hugepages-<size>: <allocation>  # enabled only if hugepages is enabled for the cluster
              requests: 
                cpu: <cpu-request>
                memory: <memory-request>
                ephemeralStorage: <ephemeral-storage-request>

Configuring replicas for PostgreSQL operator (cloud-native-postgresql)

Specify the number of replicas for the PostgreSQL operator. If you do not specify the number of replicas, the default number of replicas for the PostgreSQL operator is 1.

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  operatorConfigs:
    - name: cloud-native-postgresql
      replicas: <number-of-replicas>

Configuring a custom EDB operator

To configure a custom EDB operator, see Configuring a custom EDB operator.

Authentication settings

Changing the default cpadmin username

The IBM Cloud Pak foundational services installation creates a default cpadmin user, who is a cluster administrator. You can customize the username by adding the defaultAdminUser parameter.

Note: If you already have a user by the name cpadmin in your cluster, you must set the defaultAdminUser parameter with a custom name that is not admin before you install foundational services. This is to avoid your admin user from being removed if you uninstall foundational services later.

- name: ibm-im-operator
  spec:
    authentication:
      config:
        defaultAdminUser: <custom-username>

Delegating authentication to OpenShift (ibm-im-operator)

Authentication with Red Hat OpenShift is enabled by default. The ibm-im-operator has the following default configuration. If you do not update these parameters, authentication with OpenShift is enabled with no prefix.

- name: ibm-im-operator
  spec:
    authentication:
      config:
        roksEnabled: true
        roksURL: <your-endpoint-URL>
        roksUserPrefix: ""

You can disable the authentication, or update the parameters as required. Following are the parameter descriptions:

Assigning the cloud pak administrator privileges to an OpenShift user

If you are delegating authentication to OpenShift, you can assign the cloud pak administrator privileges to an existing OpenShift user. The user can be added to the bootstrapUserId parameter.

To add the bootstrapUserId parameter before IM service installation, see the following configuration:

- name: ibm-im-operator
  spec:
    authentication:
      config:
        bootstrapUserId: "<custom-username>"

To add the bootstrapUserId parameter after IM service installation, see Changing the default cluster administrator.

Adding custom OIDC claims

The IM service uses the default scopes and claims that WebSphere® Application Server Liberty provides. Based on your OIDC authentication requirements, you can customize the OIDC claims that are returned by the UserInfo endpoint.

To add the custom claims before you install the IM service, add the following configuration:

- name: ibm-im-operator
  spec:
    authentication:
      config:
        claimsSupported: "<list-of-claims>"
        claimsMap: "<list-of-claims-map>"
        scopeClaim: "profile=<list-of-claims-in-the-profile>"

See the following example:

apiVersion: operator.ibm.com/v3
kind: CommonService
metadata:
  name: common-service
  namespace: <your-foundational-services-namespace>
spec:
  size: medium
  services:
  - name: ibm-im-operator
    spec:
      authentication:
        config:
          claimsSupported: "name,family_name,display_name,given_name,preferred_username"
          claimsMap: "name=\"givenName\" family_name=\"givenName\" given_name=\"givenName\" preferred_username=\"givenName\" display_name=\"displayName\""
          scopeClaim: "profile=\"name,family_name,display_name,given_name,preferred_username\""

Disabling nonce

To improve security, nonce is enabled by default. Nonce associates a client session with an ID token and is used in authentication to ensure that attackers do not use old sessions.

To disable nonce, add the following configuration:

- name: ibm-im-operator
  spec:
    authentication:
      config:
        nonceEnabled: false

Adding description of the login options (ibm-idp-config-ui-operator)

You can configure multiple authentication types in your cluster. For more information, see Authentication types.

The authentication types that you configure in your cluster are displayed on the console login page. You can provide a short description of the authentication types in the ibm-idp-config-ui-operator by configuring these parameters. The description is then displayed on the console login page.

- name: ibm-idp-config-ui-operator
  spec:
    globalUIConfig:
      enterpriseLDAP: <Provide a short description about the enterprise LDAP authentication type.>
      defaultAuth: <Provide a short description about the default authentication type.>
      osAuth: <Provide a short description about the OpenShift authentication type.>
      enterpriseSAML: <Provide a short description about the enterprise SAML authentication type.>

Setting the preferred login options (ibm-im-operator)

If you configured multiple authentication types in your cluster, but you want the console login page to display any one or a selected set of the configured login options, you can set the preferredLogin: parameter. For example, preferredLogin:SAML,LDAP.

Use the following parameter values:

- name: ibm-im-operator
  spec:
    authentication:
      config:
        preferredLogin: <option1>,<option2>,<optionN>

Changing the OIDC issuer URL (ibm-im-operator)

Default configuration of OpenID Connect (OIDC) in your product uses <cluster_address>:443 in the authentication endpoints, which are used to authenticate users to Kubernetes. However, in the oidcIssuerURL, local host IP address is used, the default value of which is https://127.0.0.1:443/idauth/oidc/endpoint/OP. If required, you can change the oidcIssuerURL endpoint to use a hostname for Kubernetes authentication. If you want to use the .well-known/openid-configuration endpoint, you must update the oidcIssuerURL with the hostname that you want to use.

- name: ibm-im-operator
  spec:
    authentication:
      config:
        oidcIssuerURL: <https://<hostname>:443/oidc/endpoint/OP>

Changing the provider issuer URL (ibm-im-operator)

If you want to use the .well-known/openid-configuration endpoint, you must update the providerIssuerURL with the hostname that you want to use. You can use the endpoint to get the OIDC configuration information of the provider. The default setting is providerIssuerURL: ''.

- name: ibm-im-operator
  spec:
    authentication:
      config:
        providerIssuerURL: <https://<hostname>:443/idprovider/v1/auth/.well-known/openid-configuration

Changing the cluster name (ibm-im-operator)

The default cluster name is mycluster. You can change the cluster name by using the clusterName parameter. The cluster name is used in Cloud Resource Names (CRNs).

- name: ibm-im-operator
  spec:
    authentication:
      config:
        clusterName: <custom-name>

HA configuration

If you are configuring high availability (HA) in your cluster, add the following configuration for the IM operator:

- name: ibm-im-operator
   spec:
     authentication:
       replicas: 3

Sample ibm-im-operator operator section in the custom resource

Following is a sample configuration of the ibm-im-operator operator in the custom resource. The sample includes the authentication with Red Hat OpenShift and OIDC URL parameters.

- name: ibm-im-operator
    spec:
      authentication:
        config:
          bootStrapUserId: clusteradmin
          roksEnabled: true
          roksURL: 'https://c100-e.eu-de.containers.cloud.ibm.com:32301'
          roksUserPrefix: 'IAM#'
          oidcIssuerURL: 'https://c100-e.eu-de.containers.cloud.ibm.com:443/oidc/endpoint/OP'
          preferredLogin: ROKS

Configuring resources for IM (ibm-im-operator)

Specify resource settings. If you do not specify a setting, the default resource settings that are available in the cluster are used for IM.

  - name: ibm-im-operator
    spec:
      authentication:
        replicas: 1
