Learning

I ran into a little too many errors during this project, not the most fun but I definitely learnt a lot! I tried making a project with Blue/Green deployment before this one Repo, but couldn't resolve the errors there, so finally tried out the rolling deployment and it worked! Can't wait to try out my skills in a real world project.

Tech Stack explanation

Jenkins Stages

Build - Build docker image and update the latest version of docker image on docker hub

Lint - Linting the Dockerfile using hadolint Linting the HTML file using tidy

run production - Creates service for exposing the nginx applicaiton

run development - Pulls the latest image of Capstone Project from Docker hub Creates a new deployment using the updated docker image

Ansible

Ansible is used to control different instances and update them using rolling deployment.

New user 'ansadmin' is added on instance and ssh is configured for machines.

Kops (Kubernetes Operations)

Kubernetes Operations is used to create cluster containing two nodes and one master node.

Cluster named capstone.in is created which is connected to s3 storage s3://capstone.project.

EDIT: I missed some screenshots during submission of this project, but since I had deleted the resources, I went ahead and completed my former project: Repo
