Overriding example

Consider the following Stacktape template file named stacktape.yml

• In the template file, we are using override to change which ECS cluster is used for our container-workload ECS service.

serviceName: my-stack

resources:
  myContainer:
    type: 'container-workload'
    properties:
      containers:
        - name: myContainer
          imageConfig:
            filePath: containers/ts-container.ts
      resources:
        cpu: 0.25
        memory: 512
    overrides:
      Service:
        Cluster: 'my-custom-cluster-to-use'

  smallPostgres:
    type: 'relational-database'
    properties:
      credentials:
        masterUserName: alexandro
        masterUserPassword: <<my-secret-pass>>
      engine:
        type: postgres
        properties:
          port: 5432
          storage:
            diskSizeGB: 20
          instance:
            dbInstanceSize: db.t3.micro

Describe-resources command

describe-resources command:

• prints an overview of resources specified in the Stacktape template file
• prints all underlying Cloudformation resources which are part of the Stacktape resources.

Example: following command

stacktape describe-resources --stage my-stage --configPath stacktape.yml --region eu-west-1

used with the template shown above in the overriding example section, the output would look like this:

• The output shows resource myContainer as well as the underlying Cloudformation resources. We can also see the Service Cloudformation resource on which we used an override in overriding example.
• When referencing a resource in an override, use its descriptive name.
• To see full reference of the describe-resources command see describe-resources command page.
