INFRA (TERRAFORM) ​

DANGER

Creating/updating the infrastructure can be dangerous. Only a trained user should do those steps.

INFO

Infrastrucure is under infra/models/ into quetzal-network-editor-backend

Configuration ​

  1. Create a new .tfvars file with the name of your model infra/models/environement/<model_name>.tfvars
  • replace <model_name> with the model name, ex: quetzal-paris

Important

The name should start by "quetzal-"

the name must be unique in the AWS region (ca-central-1) (s3 bucket limitation)

  • the .tfvars file contains the executor ressources.
    quetzal_model_name      = "<model_name>"
    lambda_memory_size      = 4016
    lambda_time_limit       = 300
    lambda_storage_size     = 4016

Ressources configuration.

  • Time (secs) max: 900 (15 minutes)
  • Memory (mb) max: 10240 (10 Gb)
  • Storage (mb) max: 10240 (10 Gb)

INFO

number of vCPUs scale with memory with a max of 6.

Workspace ​

  1. Go to the infra folder (infra/models)
bash
cd infra/models
  1. Create a new workspace. Each model share the same architecture and must be in separated workspace
bash
terraform init

check the list of existing workspace (optional)

bash
terraform workspace list

create a new workspace.

bash
terraform workspace new <model_name>
  1. Select your workspace and initialize it. this will sync your local copy with the deployed terraform state
bash
terraform workspace select <model_name>
bash
terraform init

Plan ​

  1. Plan your deployment. This will create a plan of deployment. if it is a new deployment, make sure everything is created and nothing is destroy

    The plan should read : Plan: 16 to add, 0 to change, 0 to destroy.

bash
terraform plan -var-file="environments/<model_name>.tfvars"
bat
terraform plan -var-file="environments/<model_name>.tfvars" -var os="windows"

Review the plan with an Administrator before the next step to make sure it's all right.

Apply ​

  1. Apply your deployment. Make sure the plan is the same as in the previous step and press yes

    Again, the plan should read : Plan: 18 to add, 0 to change, 0 to destroy.

Windows

make sure to open docker desktop first

bash
terraform apply -var-file="environments/<model_name>.tfvars"
bat
terraform apply -var-file="environments/<model_name>.tfvars" -var os="windows"

Finish! terraform created: ​

  • S3 bucket named <model_name> (empty).
  • ECR repo to store the model docker image (with dummy docker image).
  • Lambda function (running dummy docker image) with access to the S3 bucket and cloudwatch (logs).
  • Step function to launch the lambda function from the Api.
  • IAM role and policy to add to the cognito user group (for user to acces the model when authenticated).
