Example: Ansible Hello World

Minimal Atmos setup demonstrating how stack variables are passed to Ansible playbooks.

Learn more in the Ansible Playbook Command docs.

What You'll See

• Ansible component configuration in Atmos stacks
• Variables passed from stack manifests to playbooks via --extra-vars
• Catalog pattern for shared defaults with per-environment overrides

Try It

cd examples/demo-ansible

# List all stacks
atmos list stacks

# Describe the hello-world component in dev
atmos describe component hello-world -s dev

# Run the playbook in dev
atmos ansible playbook hello-world -s dev

# Run the playbook in prod (different vars)
atmos ansible playbook hello-world -s prod

# Dry run to see the command without executing
atmos ansible playbook hello-world -s dev --dry-run
