Red Hat OpenShift Administration I: Operating a Production Cluster
An RHOCP cluster can be managed from the web console or by using the
kubectloroccommand-line interfaces (CLI).Use the
--helpoption on any command to view detailed information about the command.Projects provide isolation between your application resources.
Token authentication is the only guaranteed method to work with any RHOCP cluster, because enterprise SSO might replace the login form of the web console.
All administrative tasks require creating, viewing, and changing the API resources.
Kubernetes provides YAML- and JSON-formatted output options, which are ideal for parsing or scripting.
Operators provide the means of monitoring applications, performing health checks, managing over-the-air (OTA) updates, and ensuring that applications remain in your specified state.
The RHOCP web console incorporates useful graphs to visualize cluster and resource analytics.
The RHOCP web console provides an interface for executing Prometheus queries, visualizing metrics, and configuring alerts.
The monitoring stack is based on the Prometheus project, and it is configured to monitor the core RHOCP cluster components, by default.
RHOCP provides the ability to view logs in running containers and pods to ease troubleshooting.
You can collect resource definitions and service logs from your cluster by using the
oc adm must-gathercommand.
