OpenShift is a family of containerization software products developed by Red Hat. Red Hat OpenShift is a cloud-based Kubernetes platform that helps developers build applications. It offers automated installation, upgrades, and life cycle management throughout the container stack — the operating system, Kubernetes and cluster services, and applications — on any cloud. OpenShift gives organizations the ability to build, deploy, and scale applications faster both on-premises and in the cloud. It also protects your development infrastructure at scale with enterprise-grade security.

chef is a tool for accelerating application delivery and devops collaborations.It helps to solve the problem by treating infrastructure as code.Rather than manually changing anything,the machine setup is described in a chef recipe.It is like more than configuration management tool.

10 Advantage of Chef?

Accelerating software delivery

Increasing service resilience

Improving risk management

Managing both data center and cloud environment

Continuous delivery

scalability

consistency

A streamlined IT operations and workflow

How to install Chef Workstation?

To onstall chef workstation we need to use the following command

wget https://packages.chef.io/files/stable/chef-workstation/22.5.923/el/7/chef-workstation-22.5.923-1.el7.x86_64.rpm

One Example Program of Recipe?

file ‘/opt/first.txt’

file ‘/opt/first.txt’ do

action :delete

end

file ‘/opt/content.txt’ do

content “This is my first program of chef”

mode 755

owner root

end

Hashicorp is an organisation or company that provides us Terraform platform.Terraform is an infrastructure as code tool that lets us understand or work with both cloud and also some of the readable configuration files that we can edit , plan,apply changes,version and reuse and also share.

One example terraform program

resource “github_repository” “example” {

  name        = “example9999999”

  description = “My awesome codebase hey”

  visibility = “public”

}

provider “github” {

token = “xxxxxxx”

owner = “xxxxxxx”

}

List 5 commands in terraform and their uses

1.vi terraform.tf

2.terraform init

3.terraform plan

4.terraform apply

5.terraform destroy

It is a open source platform which is portable, extensible. It is used for managing containerized workloads and other services it also facilitates both declarative configuration and automation.It often uses k8s containerized applications to run on a cluster of hosts.The k8 uses public cloud platform.

 5 reasons of using kubernetes

Elasticity

scalability

Service discovery

Resilience

Invocation

Each kubernetes Components & write 2-3 mins about each one of them.

Container runtime:-The container runtime is the software that is responsible for running containers.

Addons:-Addons use kubernetes resources to implement cluster features.

Dns:-Cluster Dns is a Dns server in addition to the other Dns servers in your environment which serves Dna records for kubernetes services

Web Ui:-Dashboards is a genersl purpose,web based Ui for kubernetes clusters.It allows users to manage and troubleshoot applications running in the cluster and in the cluster itself

container resource monitoring:-it records generic time-series metrics about containers in a central database and provodes a Ui for browsing that data.

Cluster level logging:-it is a mechanism to responsible for saving container logs to a central log store with search/browse history

Docker is an open source containerized platform it permits developers to package applications.It is used for developing,deploying,and managing applications in a simple environment called as containers.It is used to develop different software applications in the simple environment.It builds applications,notify the applications,develop and also deploy the applications.

What is Container?

Docker containers are lightweight virtualized runtime environments for running applications. Each container represents a package of software that contains code, system tools, runtime, libraries, dependencies, and configuration files required for running a specific application. They are independent and isolated from the host and other instances running on the host.So basically containers are build on docker images…so the type of image we build that type of container we get.So build a container in the docker engine.

What are top 5 advantage of Docker? 

1.Optimization of costs

2.Speed and Agility

3.Efficiency in managing multi cloud environment

4.protection and Security

5.fixed environment

What are top 10 commands you used today and oneline explnations

docker ps -a–>The docker ps command onlyshows running containers by default. To see all containers use the -a(or–all) flag docker ps groups exposed ports into a single range if possible.

docker info–>This command displays system wide information of the docker installation.

docker version–>this will print out the docker version installed on your device, docker -v Docker version 20.10.

docker start->it helps to start a specific task in docker

docker stop–>it helps to stop the task

clear–>clears all the data

ps–>it displays running containers.

docker inspect –>docker inspect provides detailed information on constructs controlled by Docker

docker run -d httpd–> is used to run the container in the detached mode. It means your docker container will be running in the background.

docker images–>Docker images are templates used for building containers.

So process of sharing knowledge in a team have been rapidly distracting. The devolopment team even though they need some interaction between the operation team they will not contact them and they dont even ask them any thing A true combination of development and operation is nothing but devops…in devops requirement of the sources will be more because they both need operation and development sources…in this if any of them are facing problems the other team may give the ideas…time,speed, knowledge sharing,and also mainly customer satisfaction will be more efficient in the devops system.

10 Advantange of the DevOps?

gaining knowledge
knowing the correct resources
speed in produuct preparation
customer satisfaction
team collaboration
quality of the product
reducing the cost
continuous delivery
new ideas will be created
