Infinicache - Knative Version + Multi Key Replication (MK)

This branch contains a fork of Infinicache which was modified in such a way that we are able to create 2 different containers (1 for the proxy and 1 for the cache nodes) and then deploy such components in Kubernetes and Knative. A more detailed view about what the repository contains can be found in /docs.

Install Infinicache in k8s

• Setup a Google Cloud account (Google offers free credit) and enable Google Kubernetes Engine (GKE) and Google Build. Follow GCP guidelines carefully to correctly setup gcloud.

• Once you have GKE enabled, you should able to create a cluster, therefore modify file /setup/config with your desired configuration and from the proxy/ folder create a GKE cluster without Istio add-on. We do this because the Istio version of the add-on usually lags behind what Knative expects:

$ ./setup/create-gke-cluster

• Install Istio

$ ./install-istio

• Install Knative Serving

$ ./install-serving

• Install Knative Eventing

$ ./install-eventing

• (Optional, but recommended) Install observability features to enable logging, metrics, and request tracing in Serving and Eventing components:

$ ./install-monitoring

• Check if all pods are up and running:

$ kubectl get pods --all-namespaces

NB: The repository is configured to work with 20 cache nodes. If you want to modify this number you may want to change file proxy/proxy/server/config.go.

• Modify files node/node-knService.yaml and proxy/proxy-deployment.yaml with the correct iage adress

• Go to the node module and containerize the application.

$ cd node/
$ gcloud builds submit --tag gcr.io/{PROJECT-ID}/infinicache-node

• Deploy 20 local cache nodes using Knative

$ cd node/
$ ./createNodes 19

• Find the nodes addresses

$ kubectl get ksvc

• Configure the proxy with the nodes addresses. Modify the file proxy/proxy/server/config.go by modifying the LambdaAddresses array.
• Go to the proxy module and containerize the application.

$ cd proxy/
$ gcloud builds submit --tag gcr.io/{PROJECT-ID}/infinicache-proxy

• Modify file proxy/proxy-deployment.yaml with the correct image address
• Create deployment and service for proxy

$ cd proxy/
$ kubectl apply - proxy-service.yaml
$ kubectl apply -f proxy-deployment.yaml

• Wait proxy to become READY

$ kubectl get pods --watch

• SSH to Proxy pod

$ kubectl exec -it {POD-NAME} /bin/bash

• Launch Proxy

$ make start

• Run Test

$ go run client/example/main.go
