¹ We have only tested the operating systems and configurations listed. Other operating systems could be compatible, but have not been tested.

² Windows Server 2008 and 2012 require a worker machine. For more information, see Applications you can containerize using AWS App2Container.S

³ Docker must be installed to use App2Container. For more information, see Prerequisites: Set up your servers.

Note

Windows client operating systems such as Windows 7 and Windows 10 aren't supported.

Containerization features

App2Container supports the following containerization features.

Containerization feature	Linux	Windows
gMSA for connection with Active Directory	Not supported	Supported
Containerization of multiple applications in the same container	Not supported	Supported *
Containerization of applications that use multiple ports	Not supported	Supported

* Containerizing multiple applications in the same container for Windows requires that the applications are nested under a main IIS site.

For more information about configuring Windows containers with additional ports and multiple applications, see Configuring application containers.

For more information about group managed service accounts (gMSAs), see Configuring container deployment.

¹ AWS Fargate only supports certain Windows Server operating systems for running Windows containers. Select a Windows Server operating system that both Fargate and App2Container support. For more information, see Windows platform versions in the Amazon ECS User Guide for AWS Fargate.

² You can reuse certain components that App2Container created for a prior deployment. For more information about the reuseResources object, see Configuring container deployment.

³ A complex .NET application has multiple Windows .NET application components running in a single container. For more information, see Containerizing complex Windows .NET applications with App2Container.

For more information about FireLens for Amazon ECS, see Custom log routing in the Amazon Elastic Container Service Developer Guide.

For more information about deployment settings for group managed service accounts (gMSAs), see Configuring container deployment.

Pipeline support

App2Container supports AWS CodePipeline, Jenkins, and Azure DevOps Services pipeline types for both Windows and Linux. For more information about configuring pipelines, see Configuring container pipelines and Examples.
