store-functions

Common CLIs packaged in containers with a HTTP interface

About these functions:

• They are multi-arch - for armhf, arm64 and x86_64
• They are built with faas-cli
• They are built and published to GHCR as container images to avoid the Docker Hub's rate limits

You may also like the bash template for OpenFaaS, so you can perform multiple tasks with CLIs or call your scripts over HTTPS.

• Bash streaming templates

Using the functions

With OpenFaaS

You can deploy them through openfaas on Kubernetes, or openfaas on a VM with faasd.

faas-cli store deploy curl

faas-cli store deploy nodeinfo

faas-cli deploy --image ghcr.io/openfaas/alpine:latest \
  --name env --fprocess="env"

Example usage:

faas-cli store deploy nmap
echo -n "-sP 192.168.0.0/24" faas-cli invoke nmap

With Docker

Or run them ad-hoc with Docker:

docker run -p 8080:8080 --name hey \
  -d ghcr.io/openfaas/hey:latest

curl http://127.0.0.1:8080 -d "-c 5 -n 1000 https://your-service.com/"
