Docker images recipe for running SharePoint Framework Pattern and Practices samples.

In the HOSTS file on your host add:

127.0.0.1    spfx

git clone https://github.com/StfBauer/docker-spfx-pnp-samples.git

Create docker image specific to one of the sample listed on SPFX PnP Samples
For example create container for jquery-cdn sample pass in the following command:

docker build -t spfx-samples:jquery-cdn . --build-arg samplename="jquery-cdn"  

Pass in folder name to image name and tag 'spfx-samples:'.
Set 'samplename' build argument to same folder name.

docker run -h spfx --name spfx-jquery-cdn -it -p 5432:5432 -p 4321:4321 -p 35729:35729 spfx-samples:jquery-cdn

Set --name argument to your desired name. In this case spfx-jquery-cdn was used.
To exit container press CTRL+C this will exit the container.

docker start spfx-jquery-cdn

docker exec -it spfx-jquery-cdn /bin/bash

There are some know issues on Windows documented on Dockers Github page.

Windows 10 Anniversary Update and Windows Server 2016 have native support for containers. At this moment Windows supports only containers built on Windows Server Core or Nano Server and you won't be able to run this container natively on Windows. Instead you should use Docker for Windows or Docker Toolbox.
