LogDNA - Easy, beautiful logging in the cloud.

DEPRECATION NOTICE

TL;DR;

Introduction

This chart deploys LogDNA collector agents to all nodes in your cluster. Logs will ship from all containers. We extract pertinent Kubernetes metadata: pod name, container name, container id, namespace, labels, and annotations. View your logs at https://app.logdna.com or live tail using our CLI.

Prerequisites

Kubernetes 1.11.10+

Installing the Chart

Please follow directions from https://app.logdna.com/pages/add-source to obtain your LogDNA Ingestion Key.

To install the chart with the release name myrelease and namespace logdna-agent:

bash

$ helm install --set logdna.key=LOGDNA_INGESTION_KEY --namespace logdna-agent --create-namespace myrelease stable/logdna-agent

You should see logs in https://app.logdna.com in a few seconds.

Note: If you're running helm 3.0+ then you might need to run the following first (as described in the helm/charts readme):
bash
$ helm repo add stable https://kubernetes-charts.storage.googleapis.com

Tags support:

bash

$ helm install --set logdna.key=LOGDNA_INGESTION_KEY,logdna.tags=production --namespace logdna-agent --create-namespace myrelease stable/logdna-agent

Uninstalling the Chart

To uninstall/delete the myrelease deployment:

bash

$ helm --namespace logdna-agent uninstall myrelease

The command removes all the Kubernetes components associated with the chart and deletes the release.
