An examplary multi flavour app

This repo is an example of a multi-flavoured plugin app in the Arkitekt framework.

As opposed to an app with just one flavour (the default vanilla) this app can be build with different flavours, each of which can have its own set of dependencies and will generate its own docker image.

The flavours are defined in the flavours directory within the app. Each flavour is a directory containing a Dockerfile and a config.yaml, which defines selectors for the flavour.

Selectors are used to determine which flavour to use for a given enviroment and hardware configuration. In this example app, we have two flavours:

• Vanilla: The default flavour, which is used if no other flavour is selected, it has no selectors defined and will be used for all environments and hardware configurations, as a fallback.

• Cuda: A flavour which uses a base image with CUDA support and defines a selector defined as a "cuda" type selector, which can only be used on hardware with CUDA support.

Selectors are interpreted by the Port Service, which is part of the Arkitekt framework. The Port Service is responsible for the deployment of apps and will select the flavour to use based on the selectors defined in the flavour's config.yaml and the hardware configuration of the device the app is deployed to.

Experimental

This feature is still experimental and may change in the future, including the format of the config.yaml file and the way the Port Service interprets selectors. To beta test this feature, please install arkitekt cli version 0.7.0a0 or later.
