This demonstration is to show how to create a Codepipeline in AWS using Terraform.

We will be provisioning AWS Codepipeline and its supporting AWS Services like AWS Codbuild and AWS CodeCommit and AWS ECR and finally using the provisioned codepipeline to provision lambda resource and deploy a sample lambda application ref folder: lambda_bootstrap into AWS.

1. Install Terraform : link
2. Install AWS CLI : link
3. Configure AWS CLI with AWS Account do aws sts get-caller-identity for validation) : link

1. cd create-codepipeline-using-terraform/terraform

2. run terraform init

3. run terraform validate

4. run terraform plan and review the output in terminal

5. run terraform apply and review the output in terminal and when ready, type yes and hit enter

6. you should be seeing output simillar to this:

   Apply complete! Resources: 11 added, 0 changed, 0 destroyed.
   
   Outputs:
   
   codecommit = "https://git-codecommit.us-east-1.amazonaws.com/v1/repos/cloudcomps_devops_tf123_code_repo"
   
   codepipeline = "arn:aws:codepipeline:us-east-1:<account#>:cloudcomps_devops_tf123_dev_pipeline"
   
   ecrrepo = "<account#>.dkr.ecr.us-east-1.amazonaws.com/cloudcomps_devops_tf123_docker_repo"
   

7. run cd.. into the root folder and copy the codecommit info from above output.

8. run git clone <https://git-codecommit.us-east-1.amazonaws.com/v1/repos/cloudcomps_devops_tf123_code_repo>

9. If credentials are required, Generate a CodeCommit credentials from aws console for the IAM user that you logged in:

   1. Select Users from IAM (Access Management Tab)
   2. Select the user that you want to provide CodeCommit Access to.
   3. Select Security Credentials from the User information panel.
   4. Scroll down and you should be seeing a subsection HTTPS Git credentials for AWS CodeCommit
   5. Click on Generate Credentials, you should be prompted with Download credentails in cvs file.

10. Once git clone and git authentication is sucessfull, cd to cloned directory cloudcomps_devops_tf123_code_repo

11. copy lambda application code from lambda_bootstrap folder to git repo by running cp -R lambda_bootstrap cloudcomps_devops_tf123_code_repo/

12. go to cloned repo cd cloudcomps_devops_tf123_code_repo

13. push the changes to git repo by running git add. && git commit -m "Initial Commit" && git push

14. Thats it!, you can now navigate to AWS Codepipeline from aws console and check the pipeline status.

15. If everything goes well, you should be seeing an output simillar to this:
