Lambda service function

openfaas-lambda

These are sets of example that i've used when migrating aws lambda to openfaas platform. A part of documenting on how it works, I'm open for your contributions for the improvement and future reference in working projects related to openfaas.

Pre-requisite

Make sure that you successfully installed OpenFaas.

https://docs.openfaas.com/cli/install/

How do I set this up

• Update the stack.yml and replace the my docker account ${docker_name} to your docker account in each of the function.

  stack.yml

  ...
    lang: go
    handler: ./aws/openfaas/redis
    image: ${docker_name}/redis:latest
  ...
  

• Fill up the environment variable in stack.yml

  stack.yml

  ...
    environment:
      write_debug: true
      DB_URL: ''
      AWS_ID: ''
      AWS_KEY: ''
      REGION: ''
      SENTINEL_1: ''
      SENTINEL_2: ''
      SENTINEL_3: ''
      SENTINEL_PASS: ''
  ...
  

  Note: The OpenFaaS philosophy is that environment variables should be used for non-confidential configuration values only, and not used to inject secrets. I just add it here for quick and easy configuration during my testing but will get rid of this in production for sure.

• Then deploy the functions with faas-cli up -f stack.yml

TODO

• CloudStorage support
