Automating Azure infrastructure With GitHub Actions and Terraform.

Introduction to GitHub Actions

Git actions is a continuous integration and continuous delivery platform that allows us to build, test, deploy our tasks. It is an automation tool.

Practical Section

Step 1: Create a private GitHub repository

• Go to your GitHub and create a private repository

Step 2: Generate a workflow token in GitHub

• Go to your GitHub and click on your profile
• Scroll down and click on settings
• Scroll down and click on developers by your left
• Click on personal access token drop down and select tokens (classic)

• Click on generate tokens

• Name your token
• Scroll down and enable workflow

• Scroll down and click on generate tokens
• Before you exist that page, make sure you copy your token

Step 3: Create a file

• Create a file on your laptop
• Right click on it and open it with VS code
• Create a backend.tf file
• Create a HCP terraform account, create an organization and workspace. Then copy the backend code

• Go back to your VS code and paste it in the backend.tf file and do the necessary editing

Step 4: Let's push this to our GitHub repository

• After doing the above, type git init
• Type git add .
• Type git commit -m "azure backend file added"
• Type git remote add origin https://your GitHub username:your workflow [e-mail]
• Type git push -u origin main

Step 5: GitHub Action

Firstly, we will install the code pipeline in our repository

• Go to your GitHub repository, click on Action at the top
• Click on terraform configure (because we want to use terraform)
• Go back to your VS code and create a folder. Let's name it .github, workflows
• Click the workflows folder and create a file under it. Let's name it cicd.yml
• Go back to your GitHub terraform configure and copy from name: terraform to the end
• Click on the cicd.yml on your VS code and paste those things you copied
• Start editing it
• Change the name to terraform infrastructure deployment to Azure cloud (or anything)
• Remove pull_request under branch ["main"]
• Remove permission: and contents:read
• Name: under jobs, put terraform azure cloud
• Go to your GitHub repository
• Click settings on top of it
• Click on secret and variables
• Click actions
• Click on secret, and click on create new repository
• Let's name it TF_API_TOKEN
• Go to your HCP terraform, create a new token in your HCP terraform, name it git actions pipeline token
• Copy the token
• Go to the git actions secret you were creating in GitHub and paste the token you created in HCP terraform
• Click add
• go to your VS code, remove terraform format and terraform fmt-check
• Scroll down and remove if github.ref==
• type git add.
• type git commit -m "pipeline code added"
• type git push

• This is what it should look like
