Network definition spec

NOTE: Final config spec is TBD, check examples for use cases.

The network config can be provided both in json or toml format and each section can contain provider specific keys that are ignored by others, e.g. when you use the native provider all references to image/s for nodes are ignored.

settings

  • bootnode: (Boolean, default true) add bootnode to network.
  • timeout: (number) global timeout to use for spawning the whole network.
  • provider: (String, default kubernetes) Provider to use (e.g kubernetes, podman).
