env

The step-level env field adds or overrides environment variables for a single step, taking precedence over the workflow-level env.

steps:
  - command: terraform apply vpc -s plat-ue2-dev --auto-approve
    env:
      AWS_REGION: us-east-2

Step env overrides workflow-level env for matching keys. The values apply only to that step's subprocess.

This field is different from type: env, which stores variables for subsequent workflow steps using a vars map:

steps:
  - name: set_env
    type: env
    vars:
      DEPLOY_ENV: prod
