Solution (Step by Step) :
1. Determine Resource Requirements:
- Analyze tne application's memory usage. Determine tne average memory consumption per pod and the peak memory usage.
- Consider the resources available on your Kubernetes nodes.
- Define realistic requests and limits based on the application's needs and available node resources.
2. Define Resource Requests and Limits in the StatefuISet:
- Update the StatefuISet YAML configuration with resource requests and limits for the container.
- requests: Specifies the minimum amount of resources the pod will request
- limits: Specifies the maximum amount of resources the pod can use.

3. Apply the StatefulSet Configuration: - Apply the updated StatefulSet configuration to your Kubernetes cluster: bash kubectl apply -f my-critical-app-statefulset.yaml 4. Monitor Resource Usage: - Use 'kubectl describe pod' to monitor the resource usage of the pods. - Ensure that the pods are utilizing the requested resources and not exceeding the limits.

Solution (Step by Step) :
1. Install Library in Dockerfile:
- Utilize the 'COPY' instruction in your Dockerfile to copy a requirements file containing the exact library version you need.
- Use the 'RIJN' instruction to install the library from the requirements file.
- Example:
dockeflle
FROM python:3S
COPY requirements.txt
RUN pip install -r requirements-txt
COPY
CMD ["python", "app.py"l
2. Create Requirements File ('requirements.txt'):
- Create a 'requirements-txt' file within your project directory.
- Add the specific version of tne 'requests' library to this file.
- Example:
Requests==2.28.1
3. Build the Docker Image:
- Construct your Docker image using the Dockeflle.
- Run tne following command: 'docker build -t your-image-name .
4. Run the Container:
- Launch the container in Kubemetes.
- Verify that the 'requests' library with the specified version is successfully used within the container.

Explanation:
Solution (Step by Step) :
1. Define the Pod YAML: Create a Pod YAML file that includes both the main application container and the Redis sidecar container.

2. Configure Environment Variables: Set an environment variable 'REDIS HOST within the main application container to point to the Redis sidecar containers hostname- In Kubernetes, containers within the same Pod can communicate with each other using their container names. 3. Connect Application to Redis: Modifry' the application code to connect to the Redis instance using the 'REDIS HOST environment variable. For example, using a Python application with the 'redis-py' library: python import redis r = redis-Redis(host=os.environ.get('REDlS_HOST'), port=6379) # Perform Redis operations (e.g., r.set('key', 'value')) 4. Deploy the Pod: Apply the Pod YAML using 'kubectl apply -f my-app-pod.yamr 5. Verify Connectivity: Check the logs of the main application container to ensure it's successfully connecting to the Redis sidecar container Note: This approach provides local caching within the Pod, reducing external network calls and improving performance. It's important to consider potential data consistency issues if multiple Pods share the same Redis instance.
