Sk8s: a FaaS for Kubernetes

Installation

You can install the system using a Helm chart or by manually building and deploying the components.

Manual install of Sk8s FaaS

Prerequisites

You need:

• A running 1.7 Kubernetes cluster with at least 4GB of memory. These instructions assume minikube for now.

  minikube start --cpus=4 --memory=4096 --disk-size=64g

• Git installed.

• A Java 8 environment.

• A working Go environment, with a clone of Eric Bottard’s customized fabric8io/kubernetes-model.

  cd $(go env GOPATH)   #defaults to ~/go
  git clone https://github.com/ericbottard/kubernetes-model src/github.com/fabric8io/kubernetes-model/

• A clone of this repo.

git clone https://github.com/markfisher/sk8s.git

Build the kubernetes-model jar Enhanced with the Types for the CustomResources

./build-model

Setup the Kubernetes environment

Create Function and Topic Custom Resource Definitions:

kubectl apply -f config/types

Point your Docker environment to the Docker environment running in minikube:

eval $(minikube docker-env)

Build Sk8s FaaS

Build components and create Docker images:

./mvnw clean package && ./dockerize

Deploy Kafka/Zookeeper

kubectl apply -f config/kafka

Deploy Sk8s FaaS

kubectl apply -f config

Deploy Metrics (Grafana/Prometheus) and Tracing (Zipkin) Dashboards

kubectl apply -f config/prometheus
kubectl apply -f config/grafana

See how to use the dashboards.
