Install

Caution: The master branch is under heavy development. Use releases instead of the master branch to get stable software.

Prerequisites

  • Logging operator requires Kubernetes v1.22.x or later.
  • For the Helm-based installation you need Helm v3.8.1 or later.

With the 4.3.0 release, the chart is now distributed through an OCI registry.
For instructions on how to interact with OCI registries, please take a look at Use OCI-based registries. For instructions on installing the previous 4.2.3 version, see Installation for 4.2.

Validate the deployment

To verify that the installation was successful, complete the following steps.

  1. Check the status of the pods. You should see a new logging-operator pod.

    $ kubectl -n logging get pods
    NAME                                READY   STATUS    RESTARTS   AGE
    logging-operator-5df66b87c9-wgsdf   1/1     Running   0          21s
    
  2. Check the CRDs. You should see the following five new CRDs.

    $  kubectl get crd
    NAME                                    CREATED AT
