LogDNA Kubernetes Agent
LogDNA - Easy, beautiful logging in the cloud.
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, and labels. View your logs at https://app.logdna.com or live tail using our CLI.
Prerequisites
- Kubernetes 1.2+

$ helm install --name my-release \
--set logdna.key=LOGDNA_INGESTION_KEY,logdna.autoupdate=1 stable/logdna-agent
