  which was then pushed to the docker hub.
• Kubernetes-
  Understood the concepts of K8s and also made a comparison between docker
  and kubernets.
• Ansible-
  Cloud provisioning, configuration management, application management and
  intra-service orchestration along with many other IT services was looked into.
• Terraform-
  Used as an infrastructure management tool, used for building and versioning
  infrastructure.
• Jenkins-
  It was used as a continous integration tool for building and deploying applications
  automatically.

2. Project : EQUIFAX

Training Activities

Task1:
- Installed docker in ec2 instance provided and made sure the docker service is up and running.
- Check the docker version installed in the ec2 machine and write a docker file (using CentOs) to
install the Jenkins and necessary pre-requisites required for Jenkins to run.
- Created a docker image from this docker image and pushed the same to the docker registry.
- Create two docker containers using the docker image and these two containers should be
running in two different ports (8082 and 8090) and the same need to be mapped to the ec2
instance.
- When the host IP with port numbers is given the Jenkins should be running in both ports. A
pipeline is created in Jenkins to clone a repo from GitHub to host VM.

Task2:
- Install Ansible in the EC2 machine provided and create a playbook to check and install Java,
python and httpd/apache2. Once the playbook is executed successfully, do the modifications to
the httpd using another ansible playbook where it changes the port number of httpd conf file to
8081.
- Check whether the default page is coming or not, if success then clone a repo from GitHub
which consists of index.html page. Using the Ansible playbook copy the index.html page to
/var/www/html path.
- Restart the httpd service and check whether the new web page is displayed.

Task3:
- Write a single shell script where it must perform the below operations by taking user inputs and
create a file and directory, delete a file and directory, retrieve specific data from a given sample
data file, append data to the sample file at a particular requested row and modify data in the file
- All the above should be available like options and based on the selection the necessary action
should be taken.
