How to create Pull Request (PR) templates in Github repository | Creating a pull request template for your GitHub repository

Creating pull request (PR) templates in GitHub can help streamline the process of submitting PRs by providing a predefined structure. This ensures that all necessary information is included, making the review process more efficient. 

Step-by-Step Guide

1. Navigate to Your Repository:

   • Go to the GitHub repository where you want to create a PR template.

2. Create a .github Directory:

   • If it doesn't already exist, create a new directory named .github in the root of your repository. This is where GitHub looks for configuration files, including PR templates.

3. Create a PULL_REQUEST_TEMPLATE File:

• Inside the .github directory, create a file named PULL_REQUEST_TEMPLATE.md. This file will contain the template for your pull requests.

      4. Add Template Content:

• Open the PULL_REQUEST_TEMPLATE.md file and add the content you want to include in your PR template. You can use Markdown to format the template. Here’s an example of a basic PR template:

## What type of PR is this? (check all applicable)
- [ ] 🍕 New Feature
- [ ] 🎨 Enhancment Feature
- [ ] 🐛 Bug
## Describe about your code changes
<!-- 
Please do not leave this blank 
This PR [adds/removes/fixes/replaces] the [feature/bug/etc]. 
-->
## Related Feature & Documents
<!-- 
Please use this format link issue numbers: Fixes #123
-->
## Screenshots/Recordings Link In Sharepoint
<!-- Visual changes require screenshots -->

## Created Unit tests, etc?
- [ ] 👍 yes
- [ ] 🙅 no, because they aren't needed
- [ ] 🙋 no, because I need help
## Added to documentation?
- [ ] 📜 README.md
- [ ] 📕 wiki
- [ ] 🙅 no documentation needed
## [optional] Are there any post-deployment tasks we need to perform?

    5. Commit and Push:

• Commit the PULL_REQUEST_TEMPLATE.md file to your repository and push it to GitHub.

git add .github/PULL_REQUEST_TEMPLATE.md 

git commit -m "Add pull request template" 

git push origin main

Optional: Multiple Templates

If you want to offer multiple PR templates, you can place them in the .github/PULL_REQUEST_TEMPLATE/ directory. Each template should be a separate Markdown file.

Using PR templates helps maintain consistency and completeness in pull requests, making it easier for reviewers to understand and review changes. Adjust the templates according to the needs and standards of your project.

DevOps Interview Preparation Useful real time tips | Crack DevOps Interviews | How to clear DevOps Interviews

Are you failing in DevOps Interviews? Are you not be able to go to next round in the Interview process? 

First of all you need to have clear story about following five key items:

#1.     Come up with a story to talk about your back ground and over all experience 

            What are the Devops tools you have worked in, what cloud platform you are familiar ?

#2.     Have clear idea to talk about your role in your current project

           Your role instead of what whole team did

#3.     Your day to day responsibilities as a DevOps engineer

           How you spend your day 9-5. Starting with stand up, cicd, infra automation, collaborate with teams, meetings and documentation.

#4.     Be ready to talk about the challenges, how you overcome them in your current project

           What challenges you had, how did you over-come and what was the outcome?

#5.     Be clear about what you know and what you don’t know.            

• It is OK to say you don’t know or have not worked that specific tool when asked about it. Show some willingness to learn
• For e.g you may be good in CICD but not good in,  let’s say in container orchestration tools such as Kubernetes, which is OK.

Automate Azure App Service setup using Ansible and Azure DevOps pipeline | How to integrate Ansible with Azure DevOps | How to Create WebApp in Azure Cloud using Ansible

Ansible is an open-source, configuration management tool that automates cloud provisioning, configuration management, and application deployments.

To configure Azure credentials, you need the following information:

• Your Azure subscription ID and tenant ID
• The service principal application ID and secret

Pre-requisites:

• Azure account subscription, click here if you don't have one.
• Azure CLI needs to be installed.
• Service principal to create any resources in Azure cloud
• Microsoft organization

Login to Azure

az login

Enter Microsoft credentials

Run the following commands to create an Azure Service Principal:

az ad sp create-for-rbac --name ansible-azure-sp --role Contributor --scopes /subscriptions/<subscription_id>

Save the above output in a file as you will not be able retrieve later.

Create an Ansible playbook - create-linux-app-svc.yml

Create a simple playbook to create resource group in Azure and also a Azure App Service. Make sure you modify the name of the resource group, Azure WebApp and location below.

- hosts: localhost

connection: local

vars:

resource_group: myResourceGroup

webapp_name: myfirstAwesomeWebApp

plan_name: myAppServicePlan

location: eastus

tasks:

- name: Ensure resource group exists

azure_rm_resourcegroup:

name: myResourceGroup

location: East US

register: rg_result

- debug:

var: rg_result

- name: Create App Service on Linux with Java Runtime
