Installing Metering using Operator Lifecycle Manager (OLM)

Currently, installing Metering via OLM is only supported on OpenShift 4.3 and newer from the OpenShift Marketplace. If you want to install Metering into a non-OpenShift Kubernetes cluster, use the manual installation documentation.

This procedure covers:

  • Installing the metering-operator using the OperatorHub within the OpenShift web console
  • Creating a Metering resource that defines the installation configuration for the rest of the Metering stack

Installing the Metering Operator

Create a dedicated OpenShift project for Metering, and then install the Metering Operator:

  1. Create a new project/namespace called openshift-metering using the OpenShift web console (navigate to Administration > Namespaces > Create Namespace) or the oc command:
oc create namespace openshift-metering

  1. From the web console, click Catalog > OperatorHub, and search for metering-ocp to find the Metering Operator.

  2. Click the Metering card to open its package description, then click Install.

  3. In the Create Operator Subscription screen, select the openshift-metering namespace in the A specific namespace on the cluster drop-down, and specify your update channel and approval strategy. Click Subscribe to install the metering-operator into your selected namespace.

  4. On the Subscription Overview screen, the Upgrade status indicates 1 installed when the Metering Operator has finished installing. Click the 1 installed (or installed version) link to view the ClusterServiceVersion overview for the metering-operator.

From the ClusterServiceVersion overview, you can create different resources related to Metering.

Installing the Metering stack

Next, create a Metering resource that instructs the metering-operator to install the Metering stack in the namespace.

This resource holds all the top level configuration for each component (such as requests, limits, storage, etc.).

IMPORTANT: There can only be one Metering resource in the namespace containing the metering-operator. Any other configuration is not supported.

  1. From the web console, ensure you are on the ClusterServiceVersion overview page for the openshift-metering project. You can navigate to this page from Catalog > Installed Operators, then selecting the Metering operator.

  2. Under Provided APIs, click Create New on the Metering Configuration card. This opens a YAML editor where you can define your Metering installation configuration.

  3. Download the example default.yaml Metering resource and customize the YAML as desired. Enter your configuration into the YAML editor and click Create.

NOTE: All supported configuration options are documented in configuring metering.

  1. Navigate to Workloads > Pods and wait for your resources to be created and become ready.

  2. Next, verify that the ReportDataSources are beginning to import data, indicated by a valid timestamp in the EARLIEST METRIC column (this may take a few minutes). We filter out the "-raw" ReportDataSources which don't import data:

$ kubectl get reportdatasources -n $METERING_NAMESPACE | grep -v raw
NAME                                         EARLIEST METRIC        NEWEST METRIC          IMPORT START           IMPORT END             LAST IMPORT TIME       AGE

Once all pods are ready and you have verified that data is being imported, you can begin using Metering to collect and Report on your cluster. For further reading on using metering, see the using metering documentation.

NOTE: The Metering documentation refers to $METERING_NAMESPACE in most examples; this value will be openshift-metering if you followed the above instructions to create the Metering project/namespace.

Manual/CLI based OLM install

To learn more about how the OLM installation process works under the hood, or to use the CLI to install Metering via OLM, see the manual OLM install documentation.
