第1章 Installing Logging
OpenShift Container Platform Operators use custom resources (CRs) to manage applications and their components. You provide high-level configuration and settings through the CR. The Operator translates high-level directives into low-level actions, based on best practices embedded within the logic of the Operator. A custom resource definition (CRD) defines a CR and lists all the configurations available to users of the Operator. Installing an Operator creates the CRDs to generate CRs.
To get started with logging, you must install the following Operators:
- Loki Operator to manage your log store.
- Red Hat OpenShift Logging Operator to manage log collection and forwarding.
- Cluster Observability Operator (COO) to manage visualization.
You can use either the OpenShift Container Platform web console or the OpenShift Container Platform CLI to install or configure logging.
You must configure the Red Hat OpenShift Logging Operator after the Loki Operator.
1.1. Prerequisites
If you are using OKD, you have downloaded the pull secret from Red Hat OpenShift Cluster Manager as shown in "Obtaining the installation program" in the installation documentation for your platform.
If you have the pull secret, add the
redhat-operatorscatalog to theOperatorHubcustom resource (CR) as shown in "Configuring OpenShift Container Platform to use Red Hat Operators".
