Astro Local Environment

This skill helps you manage your local Airflow environment using the Astro CLI.

Two modes: Docker (default, uses containers) and Standalone (Docker-free, uses a local venv — requires Airflow 3 + uv).

To set up a new project, see the setting-up-astro-project skill. When Airflow is running, use MCP tools from authoring-dags and testing-dags skills.

Start / Stop / Restart (Docker)

# Start local Airflow (webserver at http://localhost:8080)
astro dev start

# Stop containers (preserves data)
astro dev stop

# Kill and remove volumes (clean slate)
astro dev kill

# Restart all containers
astro dev restart

# Restart specific component
astro dev restart --scheduler
astro dev restart --webserver

Default credentials: admin / admin

Restart after modifying: requirements.txt, packages.txt, Dockerfile

Standalone mode? See the next section.

Standalone Mode

Docker-free local development. Runs Airflow directly on your machine in a .venv/ managed by uv.

Requirements: Airflow 3 (runtime 3.x), uv on PATH. Not supported on Windows.

Start

# One-time: set standalone as default mode
astro config set dev.mode standalone

# Or use the flag per invocation
astro dev start --standalone

Stop / Kill / Restart

# Stop (preserves .venv)
astro dev stop

# Kill (removes .venv and .astro/standalone/ — clean slate)
astro dev kill

# Restart (preserves .venv for fast restart, use -k to kill first)
astro dev restart

If you used --standalone on start instead of setting the config, pass --standalone on every subsequent command too (stop, kill, restart, bash, run, logs, etc.).

State locations: venv in .venv/, database and logs in .astro/standalone/, DAGs from dags/.

Reverse Proxy

Run multiple Airflow projects locally without port conflicts. Works in both Docker and standalone modes.

Each project gets a hostname like <project-name>.localhost:6563. Visit http://localhost:6563 to see all active projects.

# Check proxy status and active routes
astro dev proxy status

# Force-stop proxy (auto-restarts on next astro dev start)
astro dev proxy stop

Default proxy port: 6563

Check Status

astro dev ps

View Logs

# All logs
astro dev logs

# Specific component
astro dev logs --scheduler
astro dev logs --webserver

# Follow in real-time
astro dev logs -f

Standalone: astro dev logs works the same but shows a unified log (no per-component filtering).

Run Airflow CLI Commands

# Open a shell with Airflow environment
astro dev bash

# Run Airflow CLI commands
astro dev run airflow info
astro dev run airflow dags list

Standalone: Same commands work — bash opens a venv-activated shell, run executes in the venv.

Querying the Airflow API

Use astro api airflow to query a running local Airflow instance. Prefer operation IDs over URL paths.

Defaults: localhost:8080, admin/admin (auto-detected). Override with --api-url, --username, --password.

Discovery

# List all endpoints
astro api airflow ls

# Filter by keyword
astro api airflow ls dags
astro api airflow ls task

# Show params and schema for an operation
astro api airflow describe get_dag

Key Flags

DAGs

# List all DAGs
astro api airflow get_dags

# Filter by pattern (SQL LIKE — use % wildcards)
astro api airflow get_dags -F dag_id_pattern=%etl%

# Get a specific DAG
astro api airflow get_dag -p dag_id=my_dag

# Get full details (schedule, params, etc.)
astro api airflow get_dag_details -p dag_id=my_dag

# Pause / unpause
astro api airflow patch_dag -p dag_id=my_dag -F is_paused=true
astro api airflow patch_dag -p dag_id=my_dag -F is_paused=false

# View DAG source code
astro api airflow get_dag_source -p dag_id=my_dag

# Check import errors
astro api airflow get_import_errors

DAG Runs

# List runs for a DAG
astro api airflow get_dag_runs -p dag_id=my_dag

# Trigger a run
astro api airflow trigger_dag_run -p dag_id=my_dag

# Trigger with config
astro api airflow trigger_dag_run -p dag_id=my_dag -F conf[key]=value

# Get a specific run
astro api airflow get_dag_run -p dag_id=my_dag -p dag_run_id=manual__2026-04-07

# Clear (re-run) a DAG run
astro api airflow clear_dag_run -p dag_id=my_dag -p dag_run_id=manual__2026-04-07 -F dry_run=false

Task Instances

# List task instances for a run
astro api airflow get_task_instances -p dag_id=my_dag -p dag_run_id=manual__2026-04-07

# Use ~ as wildcard (all DAGs or all runs)
astro api airflow get_task_instances -p dag_id=my_dag -p dag_run_id=~

# Get a specific task instance
astro api airflow get_task_instance -p dag_id=my_dag -p dag_run_id=manual__2026-04-07 -p task_id=extract

# Clear/retry failed tasks
astro api airflow post_clear_task_instances -p dag_id=my_dag \
  -F dag_run_id=manual__2026-04-07 -F only_failed=true -F dry_run=false

# Get task logs
astro api airflow get_log -p dag_id=my_dag -p dag_run_id=manual__2026-04-07 \
  -p task_id=extract -p try_number=1

Config & Connections

astro api airflow get_connections
astro api airflow get_variables
astro api airflow get_config

Filtering with jq

# List only DAG IDs
astro api airflow get_dags -q '.dags[].dag_id'

# Get failed task IDs from a run
astro api airflow get_task_instances -p dag_id=my_dag -p dag_run_id=~ \
  -q '[.task_instances[] | select(.state=="failed") | .task_id]'

Troubleshooting

Reset Environment

When things are broken:

astro dev kill
astro dev start

Upgrade Airflow

Test compatibility first

astro dev upgrade-test

Change version

1. Edit Dockerfile: FROM quay.io/astronomer/astro-runtime:13.0.0
2. Restart: astro dev kill && astro dev start
