# Module Workflow: Docker Runner Configuration Example
# =============================================================================
# This file demonstrates all Docker runner configuration fields at both
# the workflow level (for all steps) and step level (per-step override).

tags: docker, runner, container

# -----------------------------------------------------------------------------
# RUNNER CONFIGURATION (Workflow-Level)
# Applies to all steps unless overridden at step level
# -----------------------------------------------------------------------------

# runner: Execution environment for this workflow
# Options: host (default - local machine), docker, ssh
runner: docker

# runner_config: Configuration for the selected runner type
runner_config:
  # -------------------------------------------------------------------------
  # DOCKER-SPECIFIC CONFIGURATION
  # -------------------------------------------------------------------------

  # image: Docker image to use (required for docker runner)
  # Format: registry/image:tag or just image:tag
  image: ubuntu:22.04

  # env: Environment variables to set inside the container
  # Map of VAR_NAME: value
  env:
    MY_VAR: my-value
    API_KEY: "{{api_key}}"  # Can use template variables
    THREADS: "{{threads}}"

  # volumes: Volume mounts in docker format
  # Format: host_path:container_path[:options]
  # Options: ro (read-only), rw (read-write)
  volumes:
    - "/tmp/osmedeus:/data"
    - "{{Output}}:/output"
    - "/etc/hosts:/etc/hosts:ro"

  # network: Docker network mode
  # Options: bridge (default), host, none, container:<name>, or network name
  network: host

  # persistent: Container lifecycle mode
  # true = reuse the same container across steps (faster, state preserved)
  # false = ephemeral, create new container per step (isolated, clean state)
  persistent: true

  # -------------------------------------------------------------------------
  # COMMON CONFIGURATION (applies to docker and ssh)
  # -------------------------------------------------------------------------

  # workdir: Working directory inside the container/remote
  # Commands will execute in this directory
  workdir: /app
