DevOps Capstone Project 1_Projects_Devops BC = 2330070508

Project : Capstone I

You have been hired as a Sr. DevOps Engineer in Abode Software. They want to implement DevOps Lifecycle in their company. You have been asked to implement this lifecycle as fast as possible. Abode Software is a product-based company and their product is available on this GitHub link. website.git

Following are the specifications of the lifecycle:

1. Install the necessary software on the machines using a configuration management tool
2. Git workflow has to be implemented
3. CodeBuild should automatically be triggered once a commit is made to master branch or develop branch. a. If a commit is made to master branch, test and push to prod b. If a commit is made to develop branch, just test the product, do not push to prod
4. The code should be containerized with the help of a Dockerfile. The Dockerfile should be built every time there is a push to GitHub. Use the following pre-built container for your application: hshar/webapp The code should reside in /var/www/html
5. The above tasks should be defined in a Jenkins Pipeline with the following jobs: a. Job1 : build b. Job2 : test c. Job3 : prod

Provisioning Instances §

I create three Ubuntu 22.04 EC2 instances, each located in a public subnet and configured to have a public IP enabled. This setup ensures that the instances are accessible and can handle network traffic effectively.

I name them:

Master 10.0.1.76 Test 10.0.1.51 Prod 10.0.1.218

Master §

Installing Ansible
^aa5175 Assignment 1 – Ansible_Module 5_Devops BC = 2330070508

This is a more updated version than Assignment 1 – Ansible

---

%%Now we creates ssh key to be able to ssh into our salves following could not follow those steps cuse EC2 ssh doesnt use password%%

I generate the key by accepting the default options, simply pressing ‘Enter’ at each prompt.

I copy the contents of the public key

cat ~/.ssh/id_rsa.pub

I’ll paste the contents of id_rsa.pub in the authorize_keys file belonging to the node we want ansible to connect to “Test” and “Prod”

sudo vi ~/.ssh/authorized_keys

---

I add ‘Test’ and ‘Prod’ environments to my Ansible inventory.

%%forgot how to (the format) and looked at Assignment 1 – Ansible%%

[webservers]
Test ansible_host=10.0.1.51 ansible_user=ubuntu
Prod ansible_host=10.0.1.218 ansible_user=ubuntu

Question ansible -m ping fail

Failure

Solution: authorized_keys can NOT have space

^061158

I verify the node connection once again.

I create playbook play.yaml

Before I check syntax

We successfully ran the command ansible-playbook play.yaml with 0 failures.

%%the steps are really in Installing Jenkins On AWS %%

In addition to getting Jenkins ready, I add SSH credentials and configure agents, following the same steps from Assignment 1 – Jenkins.

%%Creating admin user Creating credentials%%

%%adding agents%%

I’m using the HelloWorld_website repository, the same one used in Case Study 1 – Jenkins. This repository includes a Dockerfile and the website’s components, such as ‘index.html’ and image files.

Dockerfile

FROM ubuntu
RUN apt-get update
RUN apt-get install apache2 -y
ADD . /var/www/html
ENTRYPOINT apachectl -D  FOREGROUND

Install apache and hosts the page in Github This Dockerfile creates a Docker image based on Ubuntu that installs and runs the Apache web server, serving the contents of HelloWorld_website from the /var/www/html directory within the container.

---

Job1 §

I have configured Job1 as a Freestyle Project. This job is designed to run in the “Test” environment using the “Develop” branch of the HelloWorld_website repository.

I insert the commands into “Execute shell” as I did in Case Study 1 – Jenkins

In the “Test” environment, I observe that within the workspace, Job1 is present, and additionally, there’s a container actively running.

I test this container by using the Public IP of the ‘Test’ server and directing traffic to port 83, which is mapped to the container.

Success

---

Job2 §

Job2 is configured as a Freestyle Project in the Jenkins setup. It is designed to run in the “Test” environment using the “main” branch.

Once again I check the “Test” environment, I observe that within the workspace, Job2 is present, and now there is a second container .

I test this container by using the Public IP of the ‘Test’ server and directing traffic this time to port 82, which is mapped to the container.

Success

---

Job 3 §

Job3 is configured as a Freestyle Project in the Jenkins setup. It is designed to run in the “Prod” environment using the “main” branch.

In the “Prod” environment, I observe that within the workspace, Job3 is present, and additionally, there’s a container actively running.

I test this container by using the Public IP of the “Prod” server and directing traffic this time to port 80 (default), which is mapped to the container.

Success
