Use `astro env` commands to manage Environment Manager objects from your terminal. These objects include environment variables, Airflow connections, Airflow variables, and metrics exports. You can scope each object to a Workspace or a Deployment, and you can link a Workspace-scoped object to specific Deployments. These commands are distinct from [`astro deployment variable`](/docs/cli/v1.43/astro-deployment-variable-create), which writes directly to a single Deployment, and [`astro deployment connection`](/docs/cli/v1.43/astro-deployment-connection-create), which writes to a Deployment's Airflow metadata database. Use `astro env` for objects that you want to share across Deployments or manage at the Workspace level. View documentation for `astro env variable`. View documentation for `astro env connection`.
