Docker

These Dockerfiles enable running PowerShell in a container for each Linux distribution we support.

This requires Docker 17.05 or newer. It also expects you to be able to run Docker without sudo. Please follow Docker's official instructions to install docker correctly.

Release

The release containers derive from the official distribution image, such as centos:7, then install dependencies, and finally install the PowerShell package.

These containers live at hub.docker.com/r/microsoft/powershell.

At about 440 megabytes, they are decently minimal, with their size being the sum of the base image (200 megabytes) plus the uncompressed package (120 megabytes), and about 120 megabytes of .NET Core and bootstrapping dependencies.

Community

The Dockerfiles in the community folder were contributed by the community and are not yet officially supported.

Examples

To run PowerShell from using a container:

$ docker run -it mcr.microsoft.com/powershell

Building the images

To build an image run ./build.ps1 -build -name <ImageFolderName>.

Example

For example to build Ubuntu 16.04/xenial, which is in ./release/ubuntu16.04:

PS /powershell-docker> ./build.ps1 -Build -Name ubuntu16.04

NanoServer-Insider Release Notes

Please be sure to use a build from the Windows Insider program, either Windows Server Insider or the Windows 10 Insider, as your Container host before trying to pull this image. Otherwise, pulling this image will fail.

Read more about the changes coming to Nano Server in future releases of Windows Server Insider here.

This is pre-release software

Windows Server Insider Preview builds may be substantially modified before they are commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here. Some product features and functionality may require additional hardware or software. These builds are for testing purposes only. Microsoft is not obligated to provide any support services for this preview software.

For more information see Using Insider Container Images and Build and run an application with or without .NET Core 2.0 or PowerShell Core 6.

Known Issues

PowerShell Get only works with CurrentUser Scope

Due to known issues with the nano-server-insider, you must specify -Scope CurrentUser when using Install-Module. Example:

Install-Module <ModuleName> -Scope CurrentUser

Telemetry

By default, PowerShell collects the OS description and the version of PowerShell (equivalent to $PSVersionTable.OS and $PSVersionTable.GitCommitId) using Application Insights. To opt-out of sending telemetry, create an environment variable called POWERSHELL_TELEMETRY_OPTOUT set to a value of 1 before starting PowerShell from the installed location. The telemetry we collect fall under the Microsoft Privacy Statement.
