第 12 章 Logging, events, and monitoring
12.1. Viewing virtual machine logs
12.1.1. Understanding virtual machine logs
Logs are collected for OpenShift Container Platform Builds, Deployments, and pods. In OpenShift Virtualization, virtual machine logs can be retrieved from the virtual machine launcher Pod in either the web console or the CLI.
The -f option follows the log output in real time, which is useful for monitoring progress and error checking.
If the launcher Pod is failing to start, use the --previous option to see the logs of the last attempt.
ErrImagePull and ImagePullBackOff errors can be caused by an incorrect Deployment configuration or problems with the images that are referenced.
