# Kubernetes Logs

If you use Docker or Podman as your container runtime, you can stream your container logs to Baselime by using Fluentbit DaemonSet as your logging driver.

First create a configuration file with the value of your Baselime API key

apiKey: "YOUR_API_KEY"

Install the Baselime Helm chart

helm repo add baselime-logs-exporter https://baselime.github.io/helm-charts
helm repo update
helm install baselime-logs-exporter baselime-logs-exporter/baselime-logs-exporter --values custom-values.yaml

Your logs should automatcally be streamed to Baselime in real-time.

Baselime works best when log messages are written as JSON blobs. For example:

package main

import (
	"log/slog"
	"os"
)

func main() {
	logger := slog.New(slog.NewJSONHandler(os.Stdout, nil))
	logger.Info("Hello, logs!", "extra", map[string]interface{}{
		"stringField": "stringVal",
		"objectField": map[string]interface{}{
			"nestedField": "nestedVal",
		},
	})
}

The Baselime DeamonSet creates an instance of a FluentBit pod in each node in your clusted. The post reads all logs written to /var/log/containers/*.log and /var/log/pods/*.log and forwards them to the Baselime back-end using your Baselime API key over HTTPS.
