Compatible operating systems and Kubernetes versions

This topic lists operating systems and Kubernetes versions that have been tested with Migrate to Containers.

Migrate to Containers supplies a tool that you use to determine VM workload's fit for migration to a container. For more information, see Using the fit assessment tool.

Source VM operating systems

Linux VMs

Migrate to Containers supports migrations of VMs to containers on Google Kubernetes Engine on the 64-bit Linux operating systems listed in the following table.

OS	Compute Engine	VMware
CentOS	6.0, 7.0, 7.0 UEFI, 8.0	6.7, 6.9, 7.6
Debian	7.0, 8.0, 9.0, 10.0	9.4, 9.6
RHEL	6.0, 7.0, 7.0 UEFI, 7.4 SAP, 7.6 SAP, 8.0	6.5, 7.5, 7.6, 8.3
SUSE	12, 12 SP3 SAP, 12 SP4 SAP, 15, 15 SAP, 15 SP1 SAP	12 SP2, 12 SP3, 12 SP4, 15
Ubuntu	12 LTS, 14 LTS, 16 LTS, 16 LTS minimal, 18 LTS, 18 LTS minimal, 18 LTS UEFI, 19.04, 19.04 minimal	12.04.5 LTS, 14.04 LTS, 16.04 LTS, 18.04.10 LTS

Windows IIS Applications

Migrate to Containers supports migrations of VMs to containers on Google Kubernetes Engine on the Windows operating systems listed in the following table:

OS	Compute Engine
Windows	Microsoft Windows Server 2008R2 or higher. Microsoft IIS 7 or higher web applications. ASP.NET and .NET Framework version 3.5 or higher. After migration, the resulting container will run Windows Server version 1909.

Warning: Dynamic disks have been deprecated by Microsoft, and have severe limitations with snapshots. Use caution when using these, especially in tandem with using snapshots for backup purposes.

Processing cluster operating systems

Linux workloads

• Ubuntu - fully supported

• Clusters with Container-Optimized OS nodes can perform migrations for workloads with file-system types of ext2, ext3, or ext4.

Windows workloads

• The processing cluster can use any OS, such as Container-Optimized OS or Ubuntu. However, you must create a node pool on the cluster that uses a Windows node image. For more information, see Configuring a processing cluster for Windows IIS Applications on Compute Engine.

Workload cluster operating systems

Linux workloads

• Ubuntu - fully supported

• Before you run your migrated workloads, you must install migctl with runtime support for Container-Optimized OS nodes on your cluster:

  migctl setup install --runtime

Windows workloads

• Windows - fully supported. Windows nodes are required to run a Windows workload.
