Profiles

A firebuild profile is a JSON file with common values used to execute various commands.

Technically, firebuild does not require a profile. Common arguments may be provided on every execution. The profile exists for two reasons:

  • it makes subsequent operations more concise by moving the tedious arguments away
  • provides extra isolation with different chroots, cache directories, and image / kernel catalogs

Profiles are stored in the /etc/firebuild/profiles directory.

Profile settings

A profile can define following settings:

  • Firecracker binary path: path to the firecracker binary
  • Jailer binary path: path to the jailer binary
  • Chroot base path: path to the chroot base directory
  • Run cache path: path to the run cache directory
  • Storage provider type: string identifying the storage provider to use
  • Storage provider arguments: storage provider specific configuration
  • Tracing configuration
