Launcher

A launcher is a component of a project that defines how compute runs on RenkuLab. Each launcher combines an Environment with a default Resource Pools & Classes configuration.

Renku supports two types of launcher:

1. Session launcher — launches an interactive, browser-based Session for coding and data exploration.
2. Job launcher — runs a non-interactive Job in the background when you submit it.

A launcher contains:

1. an Environment, which defines the software installed in the run
2. a default resource pool (see Resource Pools & Classes), which determines the compute resources available

For a Job launcher, you also configure a job command that defines what runs when the job is submitted.

A project's launchers are usable to everyone who can see the project. Anyone with access can launch a session or submit a job from a launcher configured in the project.

However, the sessions you launch and the jobs you submit are only accessible to you. They are not shared between users.
