Terraform_Project

Introduction

In this project we deploy infrastructure using code, the diagram above represents our deployment. Furthermore, we also deploy an application that consists of a simple function pushing and pulling data from a database.

PART 1 - Azure Subscription Setup

1- First open terminal and login

az login

2- Then set the subscription you wish to use

az account set --subscription = "sunscription id"

3- For your subscription create a service principle with a contributor role

az ad sp create-for-rbac --role="Contributor" --scopes="/subscriptions/sunscription id"

Please save the output of this command, it will be required later.

PART 2 - Azure DevOps Setup for Infustructure as Code

1 - Create a new organisation

2 - for your new organisation. create a new project i.e "terraform_project"

3 - On the left panel click Repos icon and clone the following repo Repo

4 - On the left panel click on Pipeline and create a New pipeline.

Connect your code to the Azure Repo Git that you cloned in step 3.

Set tf_init_plan.yaml file path in the repo. Finally, save it.

5 - Go to your pipelines and select the pipeline you just created. Click on Edit, on the far right click on the '3-dot' icon and select Triggers.

If your YAML file path is not set or was not set in step 4 then you can set it under the YAML tab.

Under the variables tab, set the following variable names and their values.

Name: Value

ARM_CLIENT_ID : XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

ARM_CLIENT_SECRET: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

ARM_SUBSCRIPTION_ID: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

ARM_TENANT_ID: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

WorkingDirectory: tf_devops_project_001

6 - Repeat step for but for the tf_apply.yaml file.

7 - Your pipelines should be set and so to test this by selecting and running on your pipelines.

PART 3 - Azure DevOps Setup for application code

1 - Under the organisation you created in PART 2, create a new project i.e App Code

2 - Select the settings icon on the bottom left and create a service connection.

3 - Complete the subscription detail using information from STEP 1.

4 - On the left panel click Repos icon and clone the following repo Repo 2

5 - On the left panel click on Pipeline and create a New pipeline.

Connect your code to the Azure Repo Git that you cloned in step 3.

Set fn_app_ci.yaml file path in the repo. Finally, save it.

6 - On the left panel click on Pipeline and select releases.

Select new release pipeline.

Under the tasks tab add a 'Azure Function App Deploy' and complete the details so that it matches the fn_app_cd.yaml file. Save it.
