Authenticating the cert-manager Operator for Red Hat OpenShift on AWS

You can configure the cloud credentials for the cert-manager Operator for Red Hat OpenShift on the AWS cluster. The cloud credentials are generated by the Cloud Credential Operator.

Configuring cloud credentials for the cert-manager Operator for Red Hat OpenShift on AWS

To configure the cloud credentials for the cert-manager Operator for Red Hat OpenShift on the AWS cluster you must generate the cloud credentials secret by creating a CredentialsRequest object, and allowing the Cloud Credential Operator.

Prerequisites

  • You have installed version 1.11.1 or later of the cert-manager Operator for Red Hat OpenShift.

  • You have configured the Cloud Credential Operator to operate in mint or passthrough mode.

Procedure

  1. Create a CredentialsRequest resource YAML file, for example, sample-credential-request.yaml, as follows:

    apiVersion: cloudcredential.openshift.io/v1
kind: CredentialsRequest
metadata:
  name: cert-manager
  namespace: openshift-cloud-credential-operator
spec:
  providerSpec:
    apiVersion: cloudcredential.openshift.io/v1
    kind: AWSProviderSpec
    statementEntries:
    - action:
      - "route53:GetChange"
      effect: Allow
      resource: "arn:aws:route53:::change/*"
    - action:
      - "route53:ChangeResourceRecordSets"
      - "route53:ListResourceRecordSets"
      effect: Allow
      resource: "arn:aws:route53:::hostedzone/*"
    - action:
      - "route53:ListHostedZonesByName"
      effect: Allow
      resource: "*"
  secretRef:
    name: aws-creds
    namespace: cert-manager
  serviceAccountNames:
  - cert-manager

  2. Create a CredentialsRequest resource by running the following command:

    $ oc create -f sample-credential-request.yaml

  3. Update the subscription object for cert-manager Operator for Red Hat OpenShift by running the following command:

    $ oc -n cert-manager-operator patch subscription openshift-cert-manager-operator --type=merge -p '{"spec":{"config":{"env":[{"name":"CLOUD_CREDENTIALS_secret_NAME","value":"aws-creds"}]}}}'
Verification

  1. Get the name of the redeployed cert-manager controller pod by running the following command:

    $ oc get pods -l app.kubernetes.io/name=cert-manager -n cert-manager
    Example output
    NAME                          READY   STATUS    RESTARTS   AGE
cert-manager-bd7fbb9fc-wvbbt  1/1     Running   0          15m39s

  2. Verify that the cert-manager controller pod is updated with AWS credential volumes that are mounted under the path specified in mountPath by running the following command:

    $ oc get -n cert-manager pod/<cert-manager_controller_pod_name> -o yaml
    Example output
    ...
spec:
  containers:
  - args:
    ...
    - mountPath: /.aws
      name: cloud-credentials
  ...
  volumes:
  ...
  - name: cloud-credentials
    secret:
      ...
      secretName: aws-creds
