-INFO[0000] Supported Runtimes are: python2.7, python3.4, python3.6, nodejs6, nodejs8, ruby2.4, php7.2, go1.10, dotnetcore2.0, java1.8, ballerina0.970.1

 Each runtime is encapsulated in a container image. The reference to these images are injected in the Kubeless configuration. You can find the source code of all runtimes in [`docker/runtime`](https://github.com/kubeless/kubeless/tree/master/docker/runtime).
