You need to create a container image for an application that uses a specific version of Node.js (v16.x). How would you define this version within your Dockerfile to ensure the application runs as expected in a Kubernetes cluster? 答案:
解題說明:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Specify Node.js Base Image:
- In your Dockerfile, start by selecting a Node.js base image from Docker Hub that matches the required version (v16.x).
- Example:
dockerfile
FROM node:16.x
2. Copy Application Code:
- Copy your Node.js application code into the Docker image.
- Example:
dockerfile
COPY
3. Install Dependencies:
- Use the 'RIJN' instruction to install any necessary Node.js dependencies using 'npm install'.
- Example:
dockerfile
RUN npm install
4. Define Startup Command:
- Specify the command to start your Node.js application within the Dockerfile_
- Example:
dockeffile
CMD ["npm", "start"]
5. Build and Deploy:
- Build your Docker image using the 'docker build' command.
- Deploy the image to your Kubernetes cluster using a Deployment or Pod.
- Ensure the container utilizes the specified Node.js version (v16.x).

A deployment is falling on the cluster due to an incorrect image being specified. Locate the deployment, and fix the problem. 答案:
解題說明:
create deploy hello-deploy --image=nginx --dry-run=client -o yaml > hello-deploy.yaml Update deployment image to nginx:1.17.4: kubectl set image deploy/hello-deploy nginx=nginx:1.17.4
問題 #59
You are running a web application within a Kubernetes cluster. The application consists of two pods, each with a resource request of 1CPU core and I GiB of memory. However, you've noticed that the application experiences performance issues during peak traffic hours. To mitigate these issues, you decide to implement resource quotas tor the namespace where the application runs. You want to ensure that the application pods receive adequate resources while preventing other applications from consuming excessive resources. Design and implement a resource quota for the namespace that sets limits for CPU and memory resources. 答案:
解題說明:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Resource Quota:
- Create a YAML file (e.g., resource-quota.yaml') containing the following resource quota configuration:
2. Apply the Resource Quota: - Apply the resource quota to the 'web-app' namespace using the following command: bash kubectl apply -f resource-quota-yaml 3. Verify the Resource Quota: - Check the status of the resource quota using the following command: bash kubectl get resourcequotas -n web-app You should see the 'web-app-quota' listed with its defined limits and requests. 4. Monitor Resource Usage: - Use the 'kubectl describe resourcequota web-app-quota -n web-apps command to monitor the current resource usage within the 'web-apps namespace- This will show you the consumed resources against the defined limits. 5. Adjust the Resource Quota: - If the resource quota is too restrictive or not restrictive enough, you can adjust the values in the 'requests' and 'limits' fields in the 'resource. quota.yaml file and reapply the resource quota using 'kubectl apply'. - The resource quota limits the total amount of resources (CPU and memory) that can be consumed by all pods in the 'web-app' namespace. - The requests' field specifies the total amount of resources that pods in the namespace can request. - The 'limits' field sets a hard limit on the total amount of resources that pods can use, preventing them from exceeding these limits. - This ensures that the web application has access to the required resources while preventing other applications in the namespace from consuming all available resources. ,
