Implementation Of AWS CodePipeline Using Terraform Step-By-Step

Step 01: Create An AWS CodeCommit Repository

• First of all, we need to create a code commit repository and afterwards we have to go to AWS developer tools and select AWS code commit.

• Create a new repository.
• Once in CodeCommit, click on the “Create repository” button.
• Provide a name for your repository and an optional description.
• You can also configure repository settings such as permissions, encryption, and triggers according to your project requirements.

• Now, upload all the terraform and other configuration files.
• Depending on your project needs, you might want to configure additional settings like repository triggers, branch policies, or encryption.
• You can set up notifications, which can be helpful to stay updated on changes to the repository.

• The following screenshosts the files that we are going to build up using terraform to setup AWS Codepipeline:

• Uploading the terraform files in terraform codepipeline repository:

Step 02: Create CodeBuild Project

• For initiating the creation of a CodeBuild project in the AWS account, the first step is to log in the AWS Codebuild service and it can be done by searching the services in the search bar or by locating it in the Developer Tools Section.
• After getting access of the Code Build anyone can easily click on the “Create build project” button in order to start building a new project and ensure to give a descriptive name your project so that it can be easily identified.

Select Service CodeBuild And Give Administrator Access:

• Configure the appropriate permissions and then select the “Roles” from the sidebar menu.
• After selecting “Roles”, choose the appropriate role and if one doesn’t exist you can easily create a new role.

• Adding Adminstration permissions to the IAM Role:

• Adding permissions such as IAM CodeBuild Role to access the CodeBuild properties.

• After that we should go to the CodeBuild section and select Create a new build while giving name as “terraform-build”. And it will result in creating a main branch.

Create CodeBuild Project

• Firstly, select the existing IAM role.

• Provide the Build specifications as ashown in the below screenshot:

• Make Amazon S3 bucket for storing and for logging while creating a new log group from inside Cloudwatch.

• Provide the logs defines options:

• Afterwards we can easily create build projects for terraform in order to Apply and Destroy.
• Now, configure the environment as the terraform plan build project.
• AWS IAM CodeBuild will be used as a role for the terraform apply build projects.

• Give buildspec_apply.yml file location and configure buildspec_apply.yml

• Overall, there are two build projects.

Step 03: Create CodePipeline Terraform Resource Provision Automation

• Navigate to the AWS Code pipeline service and afterwards click on the create pipeline.

• Click on the pipeline name and then select a service role.
• In the Source stage all the codes will be in the main branch. Meanwhile, select the detection option which is named as “AWS CodePipeline”.
• Build stage will lead to give build provider a AWS CodeBuild which is already created by two build projects.

• Now, create a AWS CodePipeline.

• After creating the pipeline we will add more stages to the pipeline and for that click on the edit pipeline.

Step 4: Click Add Stages

After clicking the stages in AWS CodePipeline,you can easily navigate to your pipeline in the AWS Management Console and if you want to edit then just click on the “Edit” button to access the pipeline’s configuration. Afterwards you can locate the position where you want to insert the new stage and for adding the new stage click on “Add stage” button. Once the new stage gets added, you can proceed to define and configure the specific actions that needs to be executed within it.

• Defining the actions to build stage.

• We successfully build the AWS CodePipeline.

Software Development includes the continuous integration of different types of technologies like (CI/CD) pipelines for automating the process of building, testing, and deploying applications. AWS CodePipeline is a fully managed CI/CD service provided by Amazon Web Services which enables us to automate the steps required to release the software changes.
