Use a Kubernetes Job and Kaniko to build an OpenFaaS function from Git

job.yaml

# Alex Ellis 2018
# Example from: https://blog.alexellis.io/quick-look-at-google-kaniko/

# Pre-steps:
# kubectl create secret generic docker-config --from-file $HOME/.docker/config.json

# Other potential optimizations (suggested by @errordeveloper)
# - Store "templates" in a permanent volume
# - Download source via "tar" instead of git clone

(Kaniko를 K8S Job으로)
@hanjoomoon @Jivvon 포크해온건데, 눈으로 봤을 땐 써볼만 해보이네요. 굳이 faas를 쓰지 않더라도 Job 형태로 가져가도 좋을듯 해요~

LGTM 입니다~~~

next step!!
