terraform

Deploys AWS infrastructure and stores state in an S3 backend. This top-level terraform repo contains AWS infrastructure that applies to all components. Each component may have additional terraform files for deploying AWS resources, see each components README.md for details.

To deploy:

1. Initialize terraform: terraform init -reconfigure -backend-config="bucket=confluence-<env>-tf-state" -backend-config="key=confluence.tfstate" -backend-config="region=us-west-2" -backend-config="profile=<named_profile>"
2. Plan terraform modifications: terraform plan -var-file="conf.tfvars" -out="tfplan"
3. Apply terraform modifications: terraform apply tfplan

<env> can be dev1, dev2, dev3 or ops

<named_profile> is the name of the profile used to authenticate to AWS

deployment script

Script to deploy Terraform AWS infrastructure

REQUIRES:

• AWS CLI (https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html)
• Terraform (https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli)

Command line arguments:

[1] s3_state_bucket: Name of the S3 bucket to store Terraform state in (no need for s3:// prefix)

[2] terraform_state_key: Name of Terraform state key (e.g. confluence.tfstate or confluence-sfn.tfstate)

[3] terraform_directory: Which directory to deploy (e.g. workflow-infrastructure)

Infrastructure example usage: deploy/deploy.sh confluence-bucket-tf-state confluence.tfstate workflow-infrastructure

Step Function example usage: deploy/deploy.sh confluence-bucket-tf-state confluence-sfn.tfstate workflow-step-function
