WARNING: Before reading this doc :-) :-)

1: As everyone needs to sign NDA with CNCF, I can’t tell you the exact question asked during the exam neither I have GB of memory, but I can give you the pointer what to expect in the exam

2: As we all know, Kubernetes world updates everyday, so some of the stuff might not be relevant after a few days/weeks/month.

3: Please don’t ask for any exam dumps or questions; that defeats the whole purpose of the exam.

I have been preparing for the Kubernetes exam for the last two years (~1…

What is Packer?

Packer is easy to use and automates the creation of any machine image.

• It integrates natively with a bunch of configuration management systems, e.g., Ansible, Puppet.
• Packer is cross-platform(Linux/Window)
• Packer uses a JSON template file and lets you define immutable infrastructure.
• It’s written in the GO language.

Installing Packer on Ubuntu

Welcome to Day 27 of 101 Days of DevOps. The topic for today is using Terraform to automate AWS Lambda and CloudWatch. On Day 23, we have discussed how to save cost by stop/start EC2 instances on a scheduled basis using AWS Lambda and CloudWatch https://www.101daysofdevops.com/courses/101-days-of-devops/lessons/day-23/. On Day 25 and Day 26, you have learned the basics of terraform.

Let combine all these concepts and create terraform code that will automate the entire process.

On Day 25, we write the bare minimum code to understand the various terraform construct; today, let extend that code further. So far, our code looks like this.

provider "aws" {
  region = "us-west-2"
}resource "aws_instance" "mytest" {ami = "ami-0bc06212a56393ee1"instance_type = "t2.micro"}

So far, we have hardcoded the value of ami…

What is a Jenkinsfile?

A Jenkinsfile is simply a text file that contains the steps needed to run the Jenkins pipeline.

Some of the advantages of using Jenkinsfile

• You can check it in the source control.
• Perform code review.
• Become a single source of truth, which can be…
