ZMON on Kubernetes
For demo purposes provide k8s templates.
Config used is in:
config.yamlPrepare K8S definitions:
./zmon-k8s.pyNext step is to run the printed commands :)
Minikube
Check that you give your VM enough resources:
minikube start --memory=4000 --cpus=3Note
PostgreSQL and Cassandra do not use persistent volumes!
Deployment
Create Namespace
kubectl create namespace zmonIf you want use the following command to set the default namespace:
kubectl config set-context minikube --namespace=zmonDependencies
kubectl create -f dependencies/cassandra/deployment.yaml
kubectl create -f dependencies/cassandra/service.yaml
kubectl create -f dependencies/kairosdb/deployment.yaml
kubectl create -f dependencies/kairosdb/service.yaml
kubectl create -f dependencies/redis/deployment.yaml
kubectl create -f dependencies/redis/service.yaml
kubectl create -f dependencies/postgresql/deployment.yaml
kubectl create -f dependencies/postgresql/service.yamlZMON source download

Depending on how you run minikube:
kubectl get pods --namespace zmon
kubectl port-forward <controller pod id> 8443:443 --namespace zmonGCE LB
Add firewall rule to allow traffic and health check from IP range: 130.211.0.0/22
