Triages issues related to a deployment and its replicas.

Tasks:
  • Check Deployment Log For Issues with `DEPLOYMENT_NAME`
  • Fetch Deployments Logs for `DEPLOYMENT_NAME` and Add to Report Show More
    Common scenarios that might relate to this command or script:
    1. Troubleshooting a Kubernetes CrashLoopBackoff event: The DevOps or Site Reliability Engineer may need to use this command to view the logs of the deployment to identify any errors or issues causing the pod to continuously restart. 2. Monitoring application performance: The engineer may use this command to view the logs of a specific deployment to monitor the performance of the application and identify any bottlenecks or errors affecting its functionality. 3. Investigating security incidents: In the event of a security incident or breach, the engineer may need to review the logs of a specific deployment to identify any unauthorized access or unusual activity within the Kubernetes cluster. 4. Debugging an application issue: When troubleshooting an issue with a specific application running on the Kubernetes cluster, the engineer may use this command to view the logs and identify the root cause of the problem. 5. Analyzing resource usage: The engineer may use this command to view the logs of a deployment to analyze the resource usage of the application and identify any inefficiencies or areas for optimization within the Kubernetes environment.
  • Check Liveness Probe Configuration for Deployment `DEPLOYMENT_NAME`
  • Check Readiness Probe Configuration for Deployment `DEPLOYMENT_NAME`
  • Inspect Container Restarts for Deployment `DEPLOYMENT_NAME` Namespace `NAMESPACE`
  • Inspect Deployment Warning Events for `DEPLOYMENT_NAME`
  • Get Deployment Workload Details For `DEPLOYMENT_NAME` and Add to Report Show More
    Common scenarios that might relate to this command or script:
    1. Troubleshooting Kubernetes CrashLoopBackoff events: When a deployment is continuously crashing and restarting, a DevOps or SRE might use this command to retrieve the YAML configuration in order to review the settings and find any misconfigurations that could be causing the issue. 2. Investigating performance issues: If there are performance issues with a specific deployment, a DevOps or SRE might use this command to view the detailed configuration and identify any potential bottlenecks or inefficiencies. 3. Auditing and documentation: In order to keep track of the configurations for different deployments, a DevOps or SRE might use this command to retrieve the YAML configuration and document it for future reference or auditing purposes. 4. Comparing configurations: When comparing the settings of different deployments or versions of a deployment, a DevOps or SRE might use this command to retrieve the YAML configuration and compare them side by side. 5. Making changes to the deployment: Before making any changes to the deployment configuration, a DevOps or SRE might use this command to retrieve the current configuration as a reference point for the updates.
