windmill v0.1.0

Low-code

Windmill — a developer platform to turn scripts (Python, TypeScript, Go, Bash, SQL) into workflows, UIs and cron jobs (an open-source Airplane/Retool/n8n alternative). Batteries-included with a bundled PostgreSQL. Deployed as a single host-networked Nomad service.

nomad-pack run windmill --registry nomploy

…or one line (add registry + run)

curl -fsSL https://packs.nomploy.com/install.sh | sh -s -- windmill

Needs nomad-pack on PATH. The script only adds the nomploy registry and runs this pack.

Back up this pack

This pack stores data in 2 Docker named volumes: windmill_dbwindmill_cache

⚠ This pack bundles a database. A cold copy of the volume can be inconsistent — for a reliable backup, dump the DB (pg_dump / mysqldump) or stop the job while backing up.

restic

# Run on the node hosting this pack. Point restic at your repo first:
#   export RESTIC_REPOSITORY="s3:https://<account>.r2.cloudflarestorage.com/<bucket>"
#   export RESTIC_PASSWORD="<repo-password>"
#   export AWS_ACCESS_KEY_ID=<key>  AWS_SECRET_ACCESS_KEY=<secret>
restic backup \
  /var/lib/docker/volumes/windmill_db/_data \
  /var/lib/docker/volumes/windmill_cache/_data

rclone (sync to S3/R2)

rclone sync /var/lib/docker/volumes/windmill_db/_data backup:<bucket>/windmill_db
rclone sync /var/lib/docker/volumes/windmill_cache/_data backup:<bucket>/windmill_cache

Paths assume the default Docker volume location (/var/lib/docker/volumes). Restore by stopping the job, restoring files into the same volume, and re-running the pack.

Readme

windmill

Windmill — a developer platform that turns scripts into workflows, UIs and cron jobs. Write Python, TypeScript, Go, Bash or SQL and get auto-generated UIs, a flow builder, schedules, approvals and an app editor — an open-source alternative to Airplane, Retool and n8n. This pack runs Windmill in standalone mode (server + embedded worker) with a bundled PostgreSQL.

Single host-networked group: windmill + postgres.

Deploy

nomad-pack registry add nomploy https://github.com/Nomploy/nomad-packs
nomad-pack run windmill --registry=nomploy

Configure

Variable	Default	Description
`port`	`8000`	Web UI port.
`base_url`	`""`	Public URL (`BASE_URL`). Empty = `http://localhost:<port>`.
`db_password`	`change-me-…`	Change this. Database password.
`image`	`ghcr.io/windmill-labs/windmill:latest`	App image. Pin a tag in production.
`postgres_image`	`postgres:16`	Bundled database image.
`data_volume`	`windmill_cache`	`/tmp/windmill` — worker dependency cache.
`db_data_volume`	`windmill_db`	PostgreSQL data — holds all Windmill state.
`db_port`	`5432`	Loopback PostgreSQL port.
`resources` / `db_resources`	…	Per-task resources.

Windmill runs its database migrations on start; the first account you create becomes the superadmin. standalone mode bundles the server and one worker in a single container — for heavier workloads, scale out with dedicated worker deployments. Postgres holds the entire state, so pin the job to the node holding the volumes with constraints and back it up.
