Preparing up the target system
We’ll walk you through the installation in a local Minikube installation. Adapt these steps to install the o12stack into your cluster. We use Homebrew to install software on the client side.
Heads up!
Before installing the observability stack into a Kubernetes cluster (maybe even a production system), we urge you to test things in a test environment!
Client
Have minikube and helm installed on your client:
brew cask install minikube
brew install kubernetes-cli helm
Kubernetes cluster
Set up Minikube on your local machine. We use the hyperkit
hypervisor on our Macs as this avoids hasseling with Oracle Virtual Box. The full
o12stack will consume more than default memory (1GB) and cpu (1). Please provide
more memory and cpu:
minikube start --vm-driver=hyperkit --memory 8192 --cpus 3
minikube addons enable ingress
minikube addons enable metrics-server
Set up the Helm server component Tiller. Check that it’s up and running:
$ helm init
Check that it’s up and running:
$ kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system tiller-deploy-69ffbf64bc-n9lss 0/1 Running 0 11s
Configure ingress domain
Configure an ingress domain (or sobdomain) to point at your cluster. If you’re running
Minikube, utilize local.o12stack.org:
sudo sed -i '' '/local.o12stack.org/d' /etc/hosts
sudo bash -c 'echo "$(minikube ip) local.o12stack.org" >> /etc/hosts'
Now your good to go, deploy the o12stack.
Disposing
When you’re done evaluating, shut everything down and dispose the cluster.
minikube stop
minikube delete
