OpenFaaS template based on Clear Linux* OS

What are these templates

Using OpenFaaS template, you can create new functions in a given programming language quickly. Here, these templates are all based on the Clear Linux* OS. They are from the published container images per the function as below.

• clearlinux:base
• clearlinux/python
• clearlinux/numpy-mp
• clearlinux/golang
• clearlinux/node

Why use these templates

Clear Linux* OS is an open source, rolling release Linux distribution optimized for performance and security, from the Cloud to the Edge, designed for customization, and manageability.

Clear Linux* OS based container images use:

• Optimized libraries that are compiled with latest compiler versions and flags.
• Software packages that follow upstream source closely and update frequently.
• An aggressive security model and best practices for CVE patching.
• A multi-staged build approach to keep a reduced container image size.
• The same container syntax as the official images to make getting started easy.

Therefore, template based on Clear Linux* OS could get above benefits as well.

How to use the template

Assume you already had deployed workable OpenFaaS on top of Kubernetes.

Proxy and Clear Linux mirror

When working behind a Proxy, you can pass proxy settings to faas-cli commands by "--build-arg".

Also to speed up the Clear Linux bundle install, you could use mirror if you are inside Intel.

For example,

faas-cli up --build-arg http_proxy=$http_proxy --build-arg https_proxy=$https_proxy --build-arg swupd_args="-u $mirror --allow-insecure-http" -f hello-openfaas.yml
