Adding Accounts

This guide should include:

  • Adding additional AWS Accounts to Clouddriver so that they’re available for Deployments
  • Background on Spinnaker’s IAM policies and configuration

Adding A Kubernetes Account

Spinnaker supports deploying to multiple cloud environments. If you’re using Kubernetes you’ll need to follow this guide

Adding Additional AWS Accounts

Spinnaker supports adding multiple AWS accounts with some users reaching 100s of accounts in production. Spinnaker uses AWS assume roles to create resources in the target account and then passes the role to a target instance profile if it’s creating an instance resource.

Spinnaker’s Account Model

In AWS, Spinnaker relies on IAM policies to access temporary keys into configured accounts by assuming a role. This allows an administrator to limit and audit the actions that Spinnaker is taking in configured accounts.

Clouddriver Configuration

For adding additional accounts into Spinnaker you’ll need to extend Clouddriver by adding your configuration into clouddriver-local.yml. Here is an example of a Clouddriver configuration file that has 3 accounts as described above.

  defaultAssumeRole: role/SpinnakerManagedProfile

    - name: prod-account
      accountId: "198765432101"
        - name: us-east-1
        - name: us-east-2
        - name: us-west-1

    - name: staging-account
      accountId: "123456789012"
        - name: us-east-1
        - name: us-west-2

    - name: service-account
      accountId: "987654321123"
        - name: us-east-1

You’ll also have to set your default account in your spinnaker-local.yml file:

      name: prod-account

Assume Roles in IAM

You will need to create a SpinnakerManagedProfile role in the target AWS account (prod-account, staging-account, service-account) and give it the correct trust policy in IAM. Below is the trust policy you give the SpinnakerManagedProfile in the target account to allow the SpinakerInstanceProfile.

  "Version": "2012-10-17",
  "Statement": [
      "Sid": "",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::987654321123:role/SpinnakerManagedProfile"
      "Action": "sts:AssumeRole"

Below is the latest EC2 policy to use for allowing SpinnakerInstanceProfile.
