Awesome

This component is responsible for provisioning Spacelift worker pools.

By default, workers are given pull access to the configured ECR, permission to assume the spacelift team role in the identity account (although you must also configure the spacelift team in the identity account to allow the workers to assume the role via trusted_role_arns), and have the following AWS managed IAM policies attached:

AmazonSSMManagedInstanceCore
AutoScalingReadOnlyAccess
AWSXRayDaemonWriteAccess
CloudWatchAgentServerPolicy

Among other things, this allows workers with SSM agent installed to be accessed via SSM Session Manager.

aws ssm start-session --target <instance-id>

Impacts on billing

While scaling the workload for Spacelift, keep in mind that each agent connection counts against your quota of self-hosted workers. The number of EC2 instances you have running is not going to affect your Spacelift bill. As an example, if you had 3 EC2 instances in your Spacelift worker pool, and you configured spacelift_agents_per_node to be 3, you would see your Spacelift bill report 9 agents being run. Take care while configuring the worker pool for your Spacelift infrastructure.

Configuration

Docker Image on ECR

Build and tag a Docker image for this repository and push to ECR. Ensure the account where this component is deployed has read-only access to the ECR repository.

API Key

Prior to deployment, the API key must exist in SSM. The key must have admin permissions.

To generate the key, please follow these instructions. Once generated, write the API key ID and secret to the SSM key store at the following locations within the same AWS account and region where the Spacelift worker pool will reside.

Key	SSM Path	Type
API ID	`/spacelift/key_id`	`SecureString`
API Key	`/spacelift/key_secret`	`SecureString`

HINT: The API key ID is displayed as an upper-case, 16-character alphanumeric value next to the key name in the API key list.

Save the keys using chamber using the correct profile for where Spacelift worker pool is provisioned

AWS_PROFILE=acme-gbl-auto-admin chamber write spacelift key_id 1234567890123456
AWS_PROFILE=acme-gbl-auto-admin chamber write spacelift key_secret abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz

IAM configuration

After provisioning the component, you must give the created instance role permission to assume the Spacelift worker role. This is done by adding iam_role_arn from the output to the trusted_role_arns list for the spacelift role in aws-teams.
