Recommended Cluster Deployment Strategy

Azure Container Service

• Azure Container Service supports DC/OS, Swarm and Kubernetes (in preview).
• Walkthrough: Kubernetes on Azure Container Service
• More Information: Kubernetes Blog: Bringing Kubernetes Support to Azure.

ACS-Engine

• The open-source core of the Azure Container Service
• Enables easy, up-front modifications of Kubernetes clusters deployed with Azure Resource Manager (ARM) Templates
• Allows for deep customization beyond what is supported in the official Azure Container Service

Future Work

These are potential projects that anyone could pick up to help Kubernetes on Azure scenarios.

1. Azure Ingress Controller

• Status: Work In Progress
• Description:
  • Build an azure-ingress-controller using Azure's ApplicationGateways

2. Azure Cluster-Autoscale Backend

• Status: Not started
• Description:
  • Build an Azure backend for cluster-autoscale.

3. Azure Federation Support

• Status: Not started
• Description:
  • Implementation of dnsprovider.

4. Azure Active Directory Authorization Plugin

• Status: Not started
• Description:
  • Implementation of an Authorization plugin to compliment Azure Active Directory OIDC Authentication

5. Azure Virtual Machine Scale Set (VMSS) Support

• Status: Not started
• Description:
  • The Azure cloudprovider only supports "loose" (non-VMSS) VMs. It should also support VMSS.

5. Miscellaneous

• Use of Managed Disks in Azure (some work is in progress on this by @khenidak)
• Performance Improvements for AzureDisk attach/detach timing. (See this issue (and referenced issues) for some background.)
