Chef is an automation tool .

chef uses pure ruby, domain specific language for writing system configuration .

It transform infrastructure in to code to a automate server deployment.

Advantage of Chef?

faster deployment

Risk management

Manage cloud as well as data center

High scability

Easy integration
How to install Chef Workstation?

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/content.txt’ do content “This is my first program of chef” mode 755 owner “janu” end

1.flexible

2.security

3.fix easier

4.Reduce development time and cost

5.fast and accurate scanning

Openshift is a cloud development platform as a service(paas) developed by red hat.

user friendly platform and helps to develop and self service platform to create , modify, and deploy applications.

A hybrid cloud platform and manage container based applications and enabling faster development.

It is an open source infrastructure as code software tool.

this helps to manage the application infrastructure -programming

2.One example terraform program

resource “github_repository” “sample” {name = “example” description = “code” visibility=”public”}

3.List of 5 terraform commands and its use

Open source platform used for managing and maintaining and deploying a group of containers.

used to manage multiple docker host that is container. Designed by google but it is maintained by the cloud native computing foundation .

1. 5 reasons of using kubernetes
   1. Scalability and portable
   2. high availability
   3. can run in any platform(developed in go)
   4. better application development
   5. open source and flexible

1. Each kubernetes Components
   1. kubelet : Responsible for conveying and passing information from the api server. It conveys to the master node to get the information to pass to the server.
   2. kubernetes proxy: It runs on every node .It is a networking service. Helps in making services available to external .
   3. Scheduler :allocation of pods and for Assigning work to worker
   4. Etcd : a value accessible to all and for Storing all Data of kubernetes clustor
   5. API sever : It as all the kubernetes api and All the Services of function and resources managed
   6. Controller Manager :for Controlling all the worker state and to handle nodes from multiple containers

allows user to create , deploy and run applications

managing software packages called containers

It allows to break down application into small services.

It is an open platform for developing, and running applications.

2…containers

fully independent APP Run time environment

create – start – stop – restart – kill – start – pause – un pause -Stop – Remove

it simplify the build, test, deploy pipelines

have isolated libraries to run the application

3….Advantages

i. Ability to run anywhere

ii. Cost effective and fast deployment

iii. flexibility

iv. Security

v. Consistent and isolated environment

4..commands

1.docker exec — access the running container

2.docker ps — list the running container

3.docker rm — used to delete stopped container

4.docker version — get the currently installed version

5.docker pull –pull the images from the docker

6.docker run –create a container from an image

7.docker stop — stop running container

8.docker kill –kills the containers by stopping its execution immediately

9.docker ps -a —show all the running and exists containers

10.docker images — list all the stored docker images

1…Combination of Development and Operations teams work together across the whole software application life cycle

designed to deliver applications and services faster than before traditional software development process.

A Continuous Loop

flow -feedback-continuous learning

2…..Advantages

1.Faster Feedback

2. Faster Development

3.workflow within organization is fast

4.team works effectively

5.High Availability

6.Better customer satisfaction

7.Delivers faster

8.Increase in productivity

9.High software quality

10.Better Collaboration
