It is an open source developed platform which enables the developers to develop and deploy their applications on the cloud infrastructure

It is a self service platform which is used to create , modify and deploy applications on based on the use and it is the openshift helps yiou to devlop,and manage constainer-based applications

It is the one of the popular container management system and it has some features which makes unique from others. Openshift is the container platform that works with kubernetes to help applications run more efficiently and it runs on the red hat enterprise os and it is one of the most widely used software option in today’s .

Openshift online providers is free starter tier, used for the experimentation, testing or any deploy when you are ready f or the move of your application to further process then you need a free tier.

Ten advantages of chef

• Easy to learn
• Automation
• Delivering all infrastructure
• Final thoughts
• It contains all the blue prints of the infrastructure
• Centralized management
• Easily management
• It can be used by the most of the cloud service provider
• It makes easy for programmer
• It follows sequential order

How to install chef workstation

• Download ChefDK
• Install ChefDK
• Verify ChefDK Installation
• Verify the ChefDK version
• Setup Chef variables
• Firewalld rules to access chef manage
• Download starter kit from chef manage gui
• Unzip starter kit

One example of recipe

file ‘hai.txt’ do

content ‘what’

end

It makes users to write code in easy way. It then generates a plan for reaching that end-state and executes the plan to provision the infrastructure. It makes you define both cloud and on-prem resources in human-readable configuration.

Example on terraform

provider “aws” {

region = “us-west-1”

}

List of five commands

Validate – Check whether the configuration is valid or not

apply – Create or update infrastructure

init – prepare your working directory for other commands

destroy – destroy previous infrastructure

console – try terraform expression at an interactive command prompt.

It was developed by google

It is a source that manages containers where containers could be a vm ‘s in order to build an application you need lot amount of containers then you will use kubernetes

Kubernetes is a portable, or we can say that it is an open source platform which is used for managing containerized services, and for automating scaling and managing of containerized applications.

Reason’s for using kuberenetes

• Portability
• Open source
• Flexibility in any environments
• Supports cloud platforms
• Scalability

Components of kubernetes

• Kubectl

It controls the process like for api connection

• Docker

It was used for containers

• Kubeadm

It was admin tool for all components

• Kubelet

It make sures that containers are running in a pod.

• Etcd

It was used for storing all the data of k8

• Schedular

It was used to assigning container to the work

• Controller Manager

It controls all the worker state

• Api

It controlling all the functions and resources of the k8

• Kube proxy

It was used for networking service

• Networking driver

It was used for networking

Docker is an easy tool which was used to do different things easier like create, deploy, and run the applications by using docker containers.

Docker is an open source platform which was used for building, testing, deploying ,managing applications and by using docker we can work and learn more containers and to know how they where used to compare virtual machines

It is a platform for deploying, running applications in containers.

What is containers

Docker container is an open source software development platform

It’s main benefit is to package applications in containers allowing them to be able to run in any systems.

Docker container is an package or a software that includes all the applications that are needed for run applications.By using docker container you can manage your infrastructure in the same ways you can manage your applications by using docker containers.

Advantages of Docker

• Ability to run Anywhere
• Flexibility
• CI efficiency
• Open Source
• Docker is fast

Commands That I have used

• Docker info

This command is used to display the information regarding docker installation

• Docker image

This command is used to execute code in docker container.

• Docker ps

This command is used to list the running containers by default

• Clear

This command was used to bring command line on top of the terminal

• Docker stop

This command is used to pass the container which you are working with

• Docker pull

This command is used for to pull images manually/default from docker hub

• Docker create

This command is used for creating new container

• History

This command is used for getting the history of the commands which where executed previously

• Docker pause

This command is used for to hold the network namespace for a while

• Docker unpause

This command is used to release from the pause

Devops = Operations+developer

It is a combination of culture, tools, practices which mix both operation and developer teams in order to deliver product with high quality with frequent collaboration between team members and end users in order to maintain the customer satisfaction of the users in order to deliver the product with high speed velocity by using automation.

Advantage of devops

• Frequent Collaboration
• Requirements changes frequently
• Automation
• Faster delivery
• Customer Satisfaction
• High Quality
• Low Cost
• Customer Feedback
• Reduce Errors
• High Efficency

Top tools used in devops

• Git
• BitBucket
• Docker
• Kubernetes
• Jenkins
• Puppet
• Visual Studio
• Phantom
• Nagios
• Vagrant

Implementaion of devops

• plan->code->Build->Test->Release->Deploy->Operate->Monitor

• Devops culture
• building ci/cd process that is continuous integration and continuous development
• using technology
• integrate by using devops tools
• mix between qa and development teams
• monitor performances
