How is this calculated?

A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). Factors without data are left out and the rest are rescaled.

Common questions

Can the crontab config be written in JSON, TOML, or YAML?

Yes, the config file can be specified in JSON, TOML, or YAML. It may be an array or a mapping, with top-level keys ignored in mapping mode.

How do I run a job in an existing container instead of starting an image?

Set the container field to the full container name or the container alias if project is set. If image is also included, container is ignored because the job starts the specified image.

Can a job trigger commands in other containers after it completes?

Yes, use the trigger field with an array of docker-crontab subset objects. Each trigger can specify image, project, container, command, or dockerargs.

How do I add environment files or volumes to a Docker job?

Use dockerargs to pass Docker run or exec command line arguments for full control. The README shows using dockerargs for env-file and volume mounts.
