Terraform is an infrastructure as code tool that lets you build, change, and version cloud and on-prem resources safely and efficiently.

Example of terraform:

terraform {

required_providers {

aws = {

source = “hashicorp/aws” version = “~> 3.27”

}

}

required_version = “>= 0.14.9”

}

provider “aws” {

profile = “default” region = “us-west-2”

}

5 commands

init: Prepare your working directory for other commands

validate: Check whether the configuration is valid

plan : Show changes required by the current configuration

apply: Create or update infrastructure

destroy: Destroy previously-created infrastructure

Kubernetes is an open-source container orchestration system for automating software deployment, management and scaling.

Why kubernetes?

 Kubernetes has greater flexibility and capacity to scale.

 help orchestrate containerization in a multitude of environments.

including hosting software on a vendor’s cloud, self-hosting by a business, or in a hybrid environment.

allowing businesses to offload some of the deployment complexity. 

Kubernete components

A Kubernetes cluster:

consists of a set of worker machines, called nodes that run containerized applications. Every cluster has at least one worker node.

apiserver:

Provides an API that serves as the front end of a Kubernetes(control panel).It is responsible for handling external and internal requests.

ETCD:

contains data about your cluster state and configuration.

Scheduler:

Assigning work(container) to workers.

Controller manager:

controlling all the state of workers.

Kube proxy:

All compute nodes contain kube-proxy, a network proxy that facilitates Kubernetes networking services.

Kubelete:

Each node contains a kubelet, which is a small application that can communicate with the Kubernetes control plane. 

Network Driver:

 networking enables containers to communicate with hosts or other containers.

 Docker is an open source containerization stage. It empowers engineers to bundle applications into containers—standardized executable components combining application source code with the working framework (OS) libraries and conditions required to run that code in any environment.

what is container?

A container could be a commonplace unit of package that packages up code and every one its dependencies therefore the application runs quickly and faithfully from one computing atmosphere to a different.

Portability of software easily

Isolation

Flexibility

scalability

Cost effective usage of resources

top 10 commands

Docker info- it displays the images, number of containers and version of docker

Docker images-Displays the number of images

Docker ps-List of runnimg containers

Docker start container- to start container

Docker rm CONTAINER- removes the container

Docker pause CONTAINER- pauses the running of container

Docker unpause CONTAINER- to restart the running of container

Docker exec -it CONTAINER bash- To enter inside the container

Docker inspect CONTAINER- detailed information on constructs controlled by Docker.

Docker run itd ubuntu – to run ubuntu in docker

devops- devolopment+opereation

these two teams are merged into a single team where the engineers work across the entire application lifecycle, from development and test to deployment to operations, and develop a range of skills not limited to a single function.

ADVANTAGES OF DEVOPS

Reduce risk of changes

optimizing the process

fast delivery

improved effectiveness

quality

business egility

correction of defects

to run modern applications

innovation

continuous delivery
