DEVELOPMENT

Pre-requisites
Access to Kubernetes cluster
First of all, you will need access to a Kubernetes cluster. The easiest way to start is minikube.
​Virtualbox - hypervisor to run a Kubernetes cluster
​Minikube - for Kubernetes cluster creation on the local machine
​Kubectl - to interact with Kubernetes cluster
Tools to build an Operator
Apart from the Kubernetes cluster, there are some tools that are needed to build and test the "Logging Operator".
Required Tools:-
​Git​
​Go​
​Docker​
​Operator SDK​
​Make​
Build Locally
To achieve this, execute this command:-
make manager
Build Image
The Logging operator gets packaged as a container image for running on the Kubernetes cluster. These instructions will guide you to build an image.
make bundle-build
Testing
If you want to play it on Kubernetes. You can use a minikube.
# Start minikube
minikube start --vm-driver virtualbox --cpus=4 --memory=8000
​
helm upgrade elastic-stack ./ -f values.yaml \
    --set elasticsearch.enabled=true \
    --set elasticsearch.master.enabled=true \
    --set elasticsearch.master.replicas=3 \
    --set elasticsearch.data.enabled=true \
    --set elasticsearch.data.replicas=3 \
    --set elasticsearch.client.enabled=true \
    --set elasticsearch.client.replicas=1 \
    --set elasticsearch.ingestion.enabled=true \
    --set elasticsearch.ingestion.replicas=1 \
    --set fluentd.enabled=true --set kibana.enabled=true \
    --namespace logging-operator --install
