1.2. Install OpenShift Platform Plus products
Copia collegamento

To install OpenShift Platform Plus, you must first install OpenShift Container Platform and then Red Hat Advanced Cluster Management. After these products are installed, you must apply the Red Hat Advanced Cluster Management policy sets to install Red Hat Quay, Red Hat OpenShift Data Foundation Essentials, and Red Hat Advanced Cluster Security.

See the Red Hat OpenShift Platform Plus policy set for detailed information about installing the products.

1.2.1. Installing OpenShift Platform Plus by using policy sets
Copia collegamento

OpenShift Container Platform uses specific policy sets to automate the installation of additional products and services. These policies ensure that your environment remains compliant and secure while you extend the platform’s capabilities across your infrastructure.

To install the policy sets using gitops, follow the steps in "Deploying policies using gitops". Use the actual path to the policy set instead of the path in the example path policygenerator/policy-sets/stable/openshift-plus. Otherwise, use the following procedure to install the policy sets by using CLI.

Prerequisites

  • Edit the policyGenerator.yaml file to remove any products that you do not want to install. You can delete the product entries or comment out the lines.

Procedure

  1. Install the PolicyGenerator plugin by following the instructions in Installing and using the PolicyGenerator Kustomize plug-in.

  2. Clone the policy-collection repository: 

    $ git clone https://github.com/stolostron/policy-collection

  3. Navigate to the policy set directory: 

    $ cd policy-collection/policygenerator/policy-sets/stable/openshift-plus

  4. Generate and apply the policies by using the following command: 

    $ kustomize build --enable-alpha-plugins | oc apply -f -

    The policy sets install the remaining products on the OpenShift Container Platform cluster.
