Application Platform for Linode Kubernetes Engine

Getting started

Helm

To install Application Platform for LKE, make sure to have a Kubernetes cluster running with at least:

• Version 1.28, 1.29 or 1.30
• A node pool with 8 vCPU and 24GB RAM
• Calico CNI installed (or any other CNI that supports K8s network policies)
• A default storage class configured
• When using the custom provider, make sure the K8s LoadBalancer Service created by APL can obtain an external IP (using a cloud load balancer or MetalLB)

[TIP]
Install APL with DNS to unlock it's full potential. Check here for more information.

Add the Helm repository:

helm repo add apl https://linode.github.io/apl-core/
helm repo update

and then install the Helm chart:

helm install apl apl/apl \
--set cluster.name=$CLUSTERNAME \
--set cluster.provider=$PROVIDER # use 'linode' for LKE or 'custom' for any other cloud/infrastructure

When the installer job is completed, follow the post installation steps.
