Installing API Server

Installing the Amphitheatre API Server with Helm on a Kubernetes cluster.

On this page

You can deploy Amphitheatre API Server on Kubernetes via helm to make it highly available. In this way, if one of the nodes on which Amphitheatre API Server is running becomes unavailable, users do not experience interruptions of service.

Pre-requisites

Kubernetes 1.19+
Helm 3.9.0+
PV provisioner support in the underlying infrastructure
ReadWriteMany volumes for deployment scaling

Add Repository

Once Helm has been set up correctly, add the repo as follows:

  helm repo add amphitheatre https://charts.amphitheatre.app

If you had already added this repo earlier, run helm repo update to retrieve the latest versions of the packages. You can then run helm search repo amphitheatre to see the charts.

Installation

To install the chart with the release name amp:

  helm upgrade --install amp amphitheatre/amphitheatre --create-namespace --namespace=amp-system

The command deploys Amphitheatre API Server on the Kubernetes cluster in the default configuration.

Metrics Server is a crucial component in Kubernetes for monitoring container resource usage and serves as a prerequisite dependency for the Stats feature in the Amphitheatre project. In the Helm Chart, the metrics-server.enabled parameter defaults to true, ensuring Metrics Server is automatically installed during the Amphitheatre installation.

However, if your cluster already has a global Metrics Server running and you wish to avoid redundant installation, you can disable the installation of Metrics Server by setting the --set metrics-server.enabled=false parameter when installing Amphitheatre.

Uninstall

  helm delete amp

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

When successfully installed, you still need to do some initial configuration work, the details of which can be found in the Initialize Amphitheatre in your infrastructure.

Troubleshooting

If you have any trouble installing Amphitheatre API Server, look for the error message in the Troubleshooting FAQ.

See the Amphitheatre official Helm charts repository for more information.
