How can I pass an output from one component to another component or action?

Last updated: February 20, 2026

ANSWER

Nuon uses Go templating, so add the component output into the other component or action.

Below is a health check action TOML file with an environment variable called ENDPOINT that takes the EC2 component's public_ip output variable as a default value.

[steps.env_vars]
ENDPOINT = "{{.nuon.components.ec2.outputs.public_ip}}"

Here is the ec2 component's Terraform outputs.tf with the public_ip

output "public_ip" {
  value = module.ec2_instance.public_ip
}
