APM Server Helm Chart

Build Status Artifact HUB

This Helm chart is a lightweight way to configure and run our official APM Server Docker image.

Warning: This functionality is in alpha and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Alpha features are not subject to the support SLA of official GA features (see supported configurations for more details).

Warning: This branch is used for development, please use the latest 7.x release for released version.

Requirements

  • Kubernetes >= 1.14
  • Helm >= 2.17.0

See supported configurations for more details.

Installing

Install released version using Helm repository

  • Add the Elastic Helm charts repo: helm repo add elastic https://helm.elastic.co

  • Install it:

    • with Helm 3: helm install apm-server elastic/apm-server
    • with Helm 2 (deprecated): helm install --name apm-server elastic/apm-server

Install development version using main branch

  • Clone the git repo: git clone [email protected]:elastic/helm-charts.git

  • Install it:

    • with Helm 3: helm install apm-server ./helm-charts/apm-server --set imageTag=8.1.0
    • with Helm 2 (deprecated): helm install --name apm-server ./helm-charts/apm-server --set imageTag=8.1.0

Upgrading

Please always check CHANGELOG.md and BREAKING_CHANGES.md before upgrading to a new chart version.

Usage notes

  • The default APM Server configuration file for this chart is configured to use an Elasticsearch endpoint as configured by the rest of these Helm charts. This can easily be overridden in the config value apmConfig.apm-server.yml.

  • Automated testing of this chart is currently only run against GKE (Google Kubernetes Engine).

  • This repo includes a number of examples configurations which can be used as a reference. They are also used in the automated testing of this chart.

FAQ

How to use APM Server with Elasticsearch with security (authentication and TLS) enabled?

This Helm chart can use existing Kubernetes secrets to setup credentials or certificates for examples. These secrets should be created outside of this chart and accessed using environment variables and volumes.

An example can be found in examples/security.
