Jobs

A job runs a one-off command inside a project's deployed image, to completion. It reuses the environment's current live image - no separate build - and inherits that environment's variables, so a command like python manage.py migrate sees the same database and configuration as your running app. Run it on demand, or schedule it with a cron.

Creating a job

From Jobs -> New Job, pick a project and environment (the image source), enter the command and a timeout, and create it. Then use Run now, or attach the job to a cron to run it on a schedule.

# database migration
python manage.py migrate

# one-off data backfill
node scripts/backfill.js --since 2024-01-01

# seed or maintenance
rails db:seed

How a run works

Each run is a fresh, one-shot container, not a change to your running app:

• orkestr places a container on a node and pulls the environment's current live image.
• It runs your command to completion, with the environment's variables injected.
• It captures stdout and stderr and the exit code, then tears the container down.
• Exit code 0 is success; anything else is recorded as a failure.

The container carries the same hardening as app containers - capabilities dropped, no new privileges, resource caps - but has no HTTP endpoint and no domain. It occupies a node slot only while running.

Run history

• Every run records status, exit code, duration, and full logs.
• Runs triggered by a cron are tagged so you can tell them from manual runs.
• The most recent runs are kept per job so history stays bounded.

Common uses

• Database migrations after (or before) a deploy.
• Backfills and data fixes against production data, in the real environment.
• Scheduled maintenance - cleanups, report generation, cache warming - paired with a cron.
• Ad-hoc operations you'd otherwise SSH in to run.

Job vs Function vs Project

• Job - run a command inside an existing app's image. Best for migrations and maintenance against real data.
• Function - a standalone HTTP handler with its own URL.
• Project - the long-running app itself.

Plan limits

• Jobs are available on the Pro plan.
• CPU and memory are plan-driven, sized like functions for predictable placement.
• Timeouts are configurable per job, up to a per-run maximum.

FAQ

Does a job affect my running app?

No. It runs in a separate one-shot container from the same image; your app container is untouched.

Will two runs of the same job overlap?

Manual runs are independent. When driven by a cron, the cron's overlap policy controls whether a new run starts while one is still going.

Where do I see the output?

On the job's run history - expand any run to see its logs and exit code.

Can a job reach my database add-on?

Yes - it runs with the environment's variables and on the network it needs, so the same connection strings your app uses are available.
