Automation powers much of modern software development these days.
And in this course, you'll learn how CI/CD works in production with Jenkins.
It covers the SDLC and branching strategies, pipelines, how to build and deploy a Dockerized app, and lots more.

Payment logic can get messy when it’s scattered across multiple microservices.
In this tutorial, @MDTARIK46263152 teaches you how to build a dedicated PayPal payment service using NestJS, gRPC, RabbitMQ, and Docker.
You’ll implement the payment flow, connect services, handle events, and build a scalable, reusable architecture.

🚨 Decoding DevOps Interview Questions:
Build Passed Locally but Fails in CI How Will You Troubleshoot ? 👇
Ans: I will connect with the developer over a call and troubleshoot it together. Here are the few things I will check:
→ Check the Error Log in CI: First, I will review the CI error logs to see the exact error message, as it helps most of the time.
→ Reproduce Locally in CI-Like Environment: I will try to run the same app using Docker locally, matching the Java, Maven, and JDK versions used by the developer.
→ Compare Local and CI Environments: I will compare environment variables, OS version, build tools (Maven or Gradle), and memory/CPU limits between local and CI.
→ Verify Secrets and Tokens: I will check secrets and tokens, as CI failures can occur due to missing Git credentials, API tokens, or Docker Hub access tokens.
→ Dependency Issues: Check if the build is pulling the correct dependencies or if any are missing.
→ File/Path Issues: Verify the correct directory is used for building the project and check for missing permissions, which is common with Linux-based CI runners.

Today I tried the viral Jan Aushadhi facewash. Here's its feedback:
1) It smoothens your face/skin.
2) It is super good for soft and sensitive skin.
3) It removes the dust and dirt of your face.
4) It maintains the moisture of your face.
5) It is super cheap.
🚨 DevOps Interview Questions:
My friend recently attended an L2 Technical Round for a DevOps Engineer role at an Product-based company.
Here are the scenario-based questions they were asked:
1. A deployment succeeds, but users receive 503 while all Pods are Running. How would you troubleshoot?
2. A Pod is stuck in CrashLoopBackOff. What do you check first?
3. Pods remain in the Pending state for over 20 minutes. How do you find the root cause?
4. The CI/CD pipeline completed successfully, but production is still serving the old version. How would you investigate?
5. A Jenkins pipeline suddenly starts failing even though no code changes were made. What would you verify first?
6. A Docker host reaches 100% disk usage. How would you safely clean it up?
7. A container exits immediately after starting. Which commands would you use to debug it?
8. Application latency jumps from 150 ms to 3 seconds. How would you isolate the bottleneck?
9. EC2 Auto Scaling doesn't launch new instances despite high CPU utilization. What would you check?
10. An EC2 instance is running, but SSH is unreachable. How would you regain access?
11. Two engineers run `terraform apply` at the same time. What issues can occur?
12. Terraform unexpectedly plans to destroy production resources. What would you verify before applying?
13. Write a Python script to find the top 5 errors from a log file. How would you optimize it for very large log files?
14. Users report issues after a Blue-Green deployment. Would you roll back immediately? Why or why not?
How many can you answer confidently without using Google? 👇
