FaaS Demo

NOTE: this has only been tested in Linux. Windows and Mac may be added at a later time.

Summary

This is a demo to that shows deployment of plain-old Java functions (POJF) that are configured and deployed via a manifest.

The invoker bundle is composed of two containers:

1. envoy
2. service

Both are configured and built by the fake-fake-pipeline project. Once the build has completed, the built Docker images are present in the local Docker instance.

The fake-fake-pipeline project also creates a docker-compose.yml file that can be used to launch the two images. The docker-compose.yml can be thought of what goes into a K8s pod in reality. Both images are always run as a unit.

The output of the pipeline will show the command to use to launch the images.

TODO: both images talk to authz server that's not in the 'pod'

Steps

First, build the projects:

$ mvn clean install

The install target will install the faas-invoker Docker image in the local Docker instance so it can be used as base by the fake-fake-pipeline to build the actual service image.

Run the deploy.sh script, giving it a git-repo-like directory. The directory must have a manifest.yml file.

For the demo, use the provided contact-functions-fake-repo directory:

$ ./deploy.sh contact-functions-fake-repo

NOTE: The AuthZ server will have to be running. It is not launched by this process. This process is to launch the 'pod' that implements the FaaS functions. The envoy image (and also the service image, but that is optional) will communicate with the AuthZ server.
