This folder contains Kubernetes manifests to deploy a logging stack composed by
Fluentd, Elasticsearch and Kibana in the logging namespace.
Before deploying, let's see what's inside of kustomization.yaml.
To deploy the logging stack, run the following command
kustomize build . | kubectl apply -f -Note that both Fluentd and Elasticsearch export metrics that Prometheus will automatically pick up once we deploy them.
Fluentd is deployed as a DaemonSet to make sure that logs collection will
automatically happen on every node.
Elasticsearch is deployed as a StatefulSet because each pod needs to provision
its own storage and to maintain a stable name across reloads. This is needed
especially if we want to have an highly-available Elasticsearch deployment.
The elasticsearch service is of type NodePort, you can access it on port
30920.
Kibana is deployed to automatically connect to the Elasticsearch instance.
The kibana service is of type NodePort, you can access it on port 30561.
