Application Platform for Linode Kubernetes Engine

Getting started

Helm

To install APL, make sure to have a Kubernetes cluster running with at least:

• Version 1.27, 1.28 or 1.29
• A node pool with at least 8 vCPU and 16GB+ RAM (more resources might be required based on the activated capabilities)
• 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)

Note

The transition from Otomi to APL is still in progress. Installing APL will use the latest Otomi release (v2.11.5).

Tip

Install APL with DNS to unlock it's full potential. Check here for more info.

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/otomi \
--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 activation steps.
