Target account

There are two options to specify to which account Takomo should deploy stacks defined in a deployment target's config sets.

• Provide a complete IAM role ARN in the deplomentRole property.
• Provide the target account's id in the accountId property and the name of the IAM role in the deploymentRoleName property.

The first option takes precedence over the second one.

Example

Let's specify target accounts for our deployment targets.

deployment/targets.yml

vars:
  cost-center: 12345
  budget: 2000

targetsSchema: budget

deploymentGroups:
  all:
    configSets: security
  all/shared:
    targets:
      - name: infra
        deploymentRole: arn:aws:iam::123456789012:role/ExampleAdmin
  all/application:
    configSets: networking
    targetsSchema: environment
    deploymentRoleName: deployer
  all/application/dev:
    targets:
      - name: dev-environment
        accountId: "222244446666"
      - name: sandbox
        accountId: "111133335555"
  all/application/prod:
    targets:
      - name: prod-environment
        accountId: "333355557777"

The infra deployment target uses the deploymentRole property to set the IAM role Takomo should use to deploy its configurations. The value for the deploymentRole property is complete IAM role ARN which also includes the target account id.

The rest of the deployment targets belong under the all/application deployment group in the deployment groups hierarchy. Therefore, they inherit the deploymentRoleName property defined by the all/application deployment group. Each target then specifies the accountId property, which Takomo combines with the deploymentRoleName property to form the complete ARN for the deployment role.
