Docker

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

This requires an up-to-date version of Docker, such as 1.12. 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.

Examples

To run PowerShell from using a container:

$ docker run -it microsoft/powershell
