Deploy Astronomer Platform on a Google Environment

Requires Terraform 0.12+

Terraform is a simple and powerful tool that lets us write, plan and create infrastructure as code. This code will allow you to efficiently provision the infrastructure required to run the Astronomer platform.

This repo uses the following Terraform modules:

Module
astronomer/astronomer-gcp/google
astronomer/astronomer-system-components/kubernetes
astronomer/astronomer/kubernetes

These modules are downloaded from Terraform Registry into a local .terraform directory.

Steps

1. Set Google application default credentials:

   gcloud auth application-default login

2. Create Terraform Variables file (terraform.tfvars):

   A sample terraform.tfvars.sample file is provided in the repo. You can remove .sample from the filename and update the values based on your environment.

   Example:

   email            = "kaxil@astronomer.io"
   deployment_id    = "staging"
   dns_managed_zone = "steven-zone"
   management_api   = "public"
   

3. Copy providers.tf.example & rename it to providers.tf and replace PROJECT with your GCP Project ID:

   cp providers.tf.example providers.tf
   
   export PROJECT=GCP_PROJECT_ID
   sed -i "s/PROJECT/$PROJECT/g" providers.tf

4. (Optional) If you want to use remote Terraform state file, copy backend.tf.example & rename it to backend.tf & replace BUCKET & REPLACE with appropriate values.

   cp backend.tf.example backend.tf
   
   export DEPLOYMENT_ID=DEPLOYMENT_ID	# Set this value
   export STATE_BUCKET=STATE_BUCKET	# Set this value
   
   sed -i "s/REPLACE/$DEPLOYMENT_ID/g" backend.tf
   sed -i "s/BUCKET/$STATE_BUCKET/g" backend.tf

5. Run the deploy.sh bash script:

   bash deploy.sh terraform.tfvars

   OR

   ./deploy.sh terraform.tfvars

   This bash script would run all the necessary Terraform steps.

Destroy Deployment

1. Run the following command:

   ./destroy.sh terraform.tfvars
