Identify the two standard ways to view container logs in GCP: the native Kubernetes CLI and the GCP managed logging service.
Full Answer
Use the command kubectl logs frontend-pod-123, View the logs in the Google Cloud Console under Cloud Logging (Logs Explorer)
There are two primary ways to view pod logs in GKE. 1) Using the Kubernetes CLI: `kubectl logs [POD_NAME]`. 2) Because GKE has built-in integration with Google Cloud's operations suite, all stdout/stderr from containers is automatically ingested into Cloud Logging, where you can query it using the Logs Explorer.
Common mistakes
Selecting Cloud Trace (which is for latency, not logs) or trying to SSH into nodes (which is an anti-pattern in Kubernetes).
