Challenge, Medium,  on  Kubernetes

Troubleshoot Pod Manifest Deployment Failure Due to Resource Constraints

Scenario

A Pod manifest is located at /home/laborant/prod-web.yaml. Deploy the Pod into the prod namespace.

The Pod manifest fails to deploy the Pod due to resource constraint violations, as the namespace enforces ResourceQuota and LimitRange policies.

Investigate the cause by examining these policies, then update the manifest so it complies with the namespace constraints and successfully deploy the Pod.

Constraints:

  • Do NOT modify container images
  • Do NOT modify container commands
  • Only adjust resource requests and limits
Hint

Check LimitRange constraints, examine current resource values in the manifest, adjust both init container and main container resources to be within max limits (200m CPU, 256Mi memory per container).

How to Author Challenges on iximiuz Labs

Instead of providing a subpar online editing experience, iximiuz Labs offers a helper CLI tool called labctl, allowing you to use your favorite text editor (or a full-featured IDE) to write content from the comfort of your local machine.

Install labctl CLI

curl -sf https://labs.iximiuz.com/cli/install.sh | sh

This will download and install the latest version of the labctl CLI. You only need to do this once per workstation.

Authorize labctl

labctl auth login

This will open a browser window asking you to authorize labctl to access your account. You need to do it after a fresh install of labctl and repeat it whenever the auth session expires.

Pull challenge content

labctl content pull challenge troubleshoot-pod-deployment-failure-2ccb7972

This will create a local copy of the challenge content in a directory named troubleshoot-pod-deployment-failure-2ccb7972. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge troubleshoot-pod-deployment-failure-2ccb7972

Run this command in a separate terminal to continuously upload your changes to the server while editing the challenge in your favorite text editor or IDE.

You can also use labctl to create, list, and delete your content. Learn more about the available commands: labctl content --help
