Ozone

ozone is the cloud native platform for hosting workshops at google developer groups.

Demo

ozone.mp4

Features

• Continous Integration with ArgoCD
• Fully self hosted Kubernetes on Microsoft Azure
• Built in Kubernetes client-go support for provisioning dynamic resources

Architecture

Ozone utilizes openvscode-server as its primary way of serving instances to users. Upon a request to start a new instance, the dynamic kubernetes controller built into ozone will provision a new deployment and nodeport service. The current infrastructure depends on infra which utilizes haproxy as a load-balancer to forward any nodeport to the worker plane nodes on the cluster.

K8s Deployment

1. Install cert-manager
2. Install cass-operator

helm repo add k8ssandra https://helm.k8ssandra.io/stable
helm repo update

helm install cass-operator k8ssandra/cass-operator -n cass-operator --create-namespace

# deploy the Cassandra Datacenter

kubectl apply -f k8s/cassandra/manifest.yaml

# create the "main" keyspace

# connect to the cluster via cqlsh
kubectl run -n ozone -it --rm --restart=Never cqlsh --image=cassandra -- cqlsh -u $CASSANDRA_USERNAME -p $CASSANDRA_PASSWORD development-dc1-all-pods-service.cass-operator.svc.cluster.local

# exec into the cqlsh pod and pull the schema
kubectl exec -it -n ozone -c cqlsh cqlsh -- /bin/bash

wget https://raw.githubusercontent.com/GlennTatum/ozone/refs/heads/main/server/data/init.cql

# in cqlsh
development-superuser@cqlsh> SOURCE 'init.cql'

3. Deploy redis

helm install my-release oci://registry-1.docker.io/bitnamicharts/redis --values k8s/redis/values.yaml
