Docker Cloud Health

Run cloud health client in a docker containr in an ec2 instance, bonus points if you run it in kubernetes.

At docker boot the cht_perfmon is started with the

Run in docker

docker run -e CLOUD_HEALTH_SECRET="YOUR_SECRET" --rm quay.io/coveo/cloud-health

Install in a Kubernetes clusters

K8S_NAMESPACE=<yourwantednamespace>
# Create the app secret
kubectl create secret -n $K8S_NAMESPACE generic cloud-health-perfmon --from-literal=cloud-health-secret="YOUR_SECRET"
# Deploy the app
kubectl apply -n $K8S_NAMESPACE -f k8s-cloud-health-perfmon-daemonset.yaml

Sadly there is a bug in facter that makes it impossible to run in a docker in a ec2 machine and still make facter know about ec2 stats. The ec2_hack.rb fixes that problem until cloud-health officially supports it.

It adds docker to the regex to match virtual container space.

      Facter.value(:virtual).match /^(xen|kvm|docker)/
