Generating and applying an init bundle for RHACS on other platforms - Installing RHACS on other platforms | Installing | Red Hat Advanced Cluster Security for Kubernetes 4.1

Generating an init bundle

Before you install the SecuredCluster resource on a cluster, you must create an init bundle. The cluster that has SecuredCluster installed and configured then uses this bundle to authenticate with Central. You can create an init bundle by using either the RHACS portal or the roxctl CLI. You then apply the init bundle by using it to create resources.

You must have the Admin user role to create an init bundle.

Generating an init bundle

Generating an init bundle by using the RHACS portal

You can create an init bundle containing secrets by using the RHACS portal.

You must have the Admin user role to create an init bundle.

Procedure

Find the address of the RHACS portal based on your exposure method:
1. For a route:
  $ oc get route central -n stackrox
2. For a load balancer:
  $ oc get service central-loadbalancer -n stackrox
3. For port forward:
  1. Run the following command:
    
    $ oc port-forward svc/central 18443:443 -n stackrox
  2. Navigate to https://localhost:18443/.
On the RHACS portal, navigate to Platform Configuration → Integrations.
Navigate to the Authentication Tokens section and click on Cluster Init Bundle.
Click Generate bundle.
Enter a name for the cluster init bundle and click Generate.
1. If you are installing using Helm charts, click Download Helm Values File to download the generated bundle.
2. If you are installing using the Operator, click Download Kubernetes Secret File to download the generated bundle.

Store this bundle securely because it contains secrets. You can use the same bundle to create multiple secured clusters.

Next steps

Apply the init bundle by creating a resource on the secured cluster.
Install secured cluster services on each cluster.

Generating an init bundle by using the roxctl CLI

You can create an init bundle with secrets by using the roxctl CLI.

You must have the Admin user role to create init bundles.

Prerequisites

You have configured the ROX_API_TOKEN and the ROX_CENTRAL_ADDRESS environment variables.

Set the ROX_API_TOKEN and the ROX_CENTRAL_ADDRESS environment variables:

$ export ROX_API_TOKEN=<api_token>

$ export ROX_CENTRAL_ADDRESS=<address>:<port_number>

Procedure

Run the following command to generate a cluster init bundle containing secrets:

For Helm installations:

$ roxctl -e "$ROX_CENTRAL_ADDRESS" \
  central init-bundles generate <cluster_init_bundle_name> \
  --output cluster_init_bundle.yaml

For Operator installations:

$ roxctl -e "$ROX_CENTRAL_ADDRESS" \
  central init-bundles generate <cluster_init_bundle_name> \
  --output-secrets cluster_init_bundle.yaml

Ensure that you store this bundle securely because it contains secrets. You can use the same bundle to set up multiple secured clusters.

Creating resources by using the init bundle

Next Step

Before you install secured clusters, you must use the init bundle to create the required resources on the cluster that will allow the services on the secured clusters to communicate with Central.

If you are installing by using Helm charts, do not perform this step. Complete the installation by using Helm; See "Installing RHACS on secured clusters by using Helm charts" in the additional resources section.

Prerequisites

You must have generated an init bundle containing secrets.

Procedure

Using the kubectl CLI, run the following commands to create the resources:

$ kubectl create namespace stackrox (1)
$ kubectl create -f <init_bundle>.yaml \ (2)
  -n <stackrox> (3)

1	Create the project where secured cluster resources will be installed. This example uses `stackrox`.
2	Specify the file name of the init bundle containing the secrets.
3	Specify the project name that you created. This example uses `stackrox`.

Next Step

Install RHACS secured cluster services in all clusters that you want to monitor.
