Playing around with Terraform

Terraform Pipeline Example

Development

Amazon Web Services (AWS)

Initial Setup

This will create a code pipeline in AWS.

NOTE: We work from aws directory so make sure to start there.

cd aws

NOTE: The Github Connection is a Hardcoded ARN as there is manual approval involved.

cd pipelines
terraform init
terraform plan
terraform apply

Deploying a development setup per user

Add the following to your ~/.bashrc or ~/.zshrc file.

export TF_VAR_disambiguator="$USER"

Check out a workspace in terraform. This makes sure you have a different state file saved.

terraform workspace new $USER

Deploying EC2 instance.

cd dev
terraform plan
terraform apply

This should create an EC2 instance called ExampleServer-${USER}. This is useful for checking changes before committing.

Once all has been tested, you can push your code and it should create an EC2 instance called ExampleServer-dev through the pipeline.

Pipeline Updates

When updating the pipeline to add new stages. You update the code and do a terraform plan. Once code is committed, the pipeline will automatically update itself.
