DEVELOPMENT

A development guide for logging operator

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
