When inspecting configurations in Kubernetes, here are the key things to look for:
-
Metadata:
- Name: Ensure the resource has a unique name.
- Namespace: Check the namespace for proper resource organization.
-
Labels and Annotations:
- Labels: Verify that labels are correctly applied for selection and organization.
- Annotations: Look for additional metadata that may provide context or configuration details.
-
Spec:
- Containers: Check the container images, versions, and configurations (e.g., environment variables, command).
- Ports: Ensure the correct ports are exposed and mapped.
- Resources: Review resource requests and limits for CPU and memory.
-
Volumes:
- Volume Mounts: Confirm that volumes are correctly defined and mounted in containers.
- Persistent Volumes: Check for proper configuration of persistent storage if needed.
-
Networking:
- Service Accounts: Ensure the correct service account is used for permissions.
- Network Policies: Review any network policies that may affect communication.
-
Health Checks:
- Liveness and Readiness Probes: Verify that probes are configured to ensure the application is running and ready to serve traffic.
-
Status:
- Conditions: Look for the current state of the resource (e.g., running, pending).
- Events: Check for any recent events that may indicate issues or warnings.
By focusing on these areas, you can effectively assess the configuration and troubleshoot any potential issues.
