Generating an init bundle for Kubernetes secured clusters

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 the ACS Console. 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.

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

  1. 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/.

  2. On the RHACS portal, navigate to Platform Configuration → Integrations.

  3. Navigate to the Authentication Tokens section and click on Cluster Init Bundle.

  4. Click Generate bundle.

  5. 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

  1. Apply the init bundle by creating a resource on the secured cluster.

  2. 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:

    1. Set the ROX_API_TOKEN by running the following command:

      $ export ROX_API_TOKEN=<api_token>

    2. Set the ROX_CENTRAL_ADDRESS environment variable by running the following command:

      $ export ROX_CENTRAL_ADDRESS=<address>:<port_number>

In RHACS Cloud Service, when using roxctl commands that require the Central address, use the Central instance address as displayed in the Instance Details section of the Red Hat Hybrid Cloud Console. For example, use acs-ABCD12345.acs.rhcloud.com instead of acs-data-ABCD12345.acs.rhcloud.com.
Procedure

  • To generate a cluster init bundle containing secrets for Helm installations, run the following command:

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

  • To generate a cluster init bundle containing secrets for Operator installations, run the following command:

    $ 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.
