Resource quotas per namespace in Kubernetes - Mini Project: Build & Apply

Resource quotas per namespace

📖 Scenario: You are managing a Kubernetes cluster for a small company. To keep resources fair and avoid one team using too much, you want to set limits on how much CPU and memory each team can use in their own namespace.

🎯 Goal: Create a Kubernetes resource quota for a namespace called team-a that limits CPU and memory usage. Then, check the quota status.

📋 What You'll Learn

Create a namespace called team-a

Create a resource quota named team-a-quota in the team-a namespace

Limit CPU requests to 2 cores and memory requests to 4Gi

Limit CPU limits to 4 cores and memory limits to 8Gi

Display the resource quota details for team-a namespace

💡 Why This Matters

🌍 Real World

Resource quotas help teams share a Kubernetes cluster fairly by limiting how much CPU and memory each namespace can use.

💼 Career

Setting and managing resource quotas is a common task for Kubernetes administrators and DevOps engineers to ensure cluster stability and fair resource distribution.

1

Create the team-a namespace

Write the kubectl command to create a namespace called team-a.

Kubernetes

# Your code here

Need a hint?

Use kubectl create namespace team-a to create the namespace.

2

Create the resource quota YAML file

Create a YAML file named team-a-quota.yaml with a resource quota named team-a-quota in the team-a namespace. It should limit CPU requests to 2 cores, memory requests to 4Gi, CPU limits to 4 cores, and memory limits to 8Gi.

Kubernetes

# Write the YAML content for resource quota below

Need a hint?

Remember to set apiVersion: v1, kind: ResourceQuota, and specify hard limits under spec.

3

Apply the resource quota to the team-a namespace

Use the kubectl command to apply the team-a-quota.yaml file to the cluster.

Kubernetes

# Your code here

Need a hint?

Use kubectl apply -f team-a-quota.yaml to apply the quota.

4

Check the resource quota status

Write the kubectl command to show the resource quota details for the team-a namespace.

Kubernetes

# Your code here

Need a hint?

Use kubectl get resourcequota -n team-a to see the quota status.
