App Platform example with OpenFaaS

app-platform-openfaas

This repo shows how to use OpenFaaS templates with App Platform

Since App Platform doesn't know about openfaas templates and faas-cli, we can give it some hints and use the "shrinkwrap" feature of the CLI along with App Platform's Dockerfile build pack.

Get faas-cli:

faas-cli template store list

faas-cli template store pull golang-middleware

faas-cli new --lang golang-middleware my-function

Then hack on your code at my-function/handler.go and add a go.mod in the my-function folder if you wish.

Next shrinkwrap the function into a build context:

faas-cli build --shrinkwrap -f my-function.yml

This creates a build context and Dockerfile at build/my-function

Now copy all the contents to the root of the folder:

cp -r build/my-function/* ../

Do a commit and your function will be built and deployed by AP.

You can also just run make build which automates the above.

What next?

It would be nice if DO added support for faas-cli and openfaas templates

We could also copy the build output to a different directory perhaps like dist and point AP to do its build from that folder.
