AKS-Engine FAQ

This page provides help with the most common questions about AKS-Engine.

What's the Difference Between AKS and AKS-Engine?

Azure Kubernetes Service (AKS) is a Microsoft Azure service that supports fully managed Kubernetes clusters. AKS-Engine is an Azure open source project that creates Kubernetes clusters with your custom requirements. AKS uses AKS-Engine internally, but they are not the same.

AKS clusters can be created in the Azure portal or with az aks create in the Azure command-line tool. AKS-Engine clusters can be created with aks-engine deploy in the AKS-Engine command-line tool, or by generating the ARM templates with aks-engine generate and deploying them as a separate step.

What's the Difference Between acs-engine and aks-engine?

AKS-Engine is the next version of the ACS-Engine project. AKS-Engine supports current and future versions of Kubernetes, while ACS-Engine also supported the Docker Swarm and Mesos DC/OS container orchestrators.

Can I Scale or Upgrade an acs-engine Cluster with aks-engine?

Yes.

Is ACS-Engine Still Active?

No further development or releases in ACS-Engine are planned. AKS-Engine is a backward-compatible continuation of ACS-Engine, so all fixes and new features will target AKS-Engine.

Can I Build an AKS Cluster with aks-engine?

No, Azure Kubernetes Service itself is the way to create a supported, managed AKS cluster. AKS-Engine shares some code with AKS, but does not create managed clusters.

Should I use the latest aks-engine release if I was previously using acs-engine?

Yes. aks-engine v0.27.0 is a continuation of acs-engine v0.26.2 with all the Kubernetes fixes and features included in v0.26.2 and more.
