Play With Docker gives you the experience of having a free Alpine Linux Virtual Machine in the cloud where you can build and run Docker containers and even create clusters with Docker features like Swarm Mode.

Under the hood DIND or Docker-in-Docker is used to give the effect of multiple VMs/PCs.

A live version is available at: http://play-with-docker.com/

Docker 1.13+ is required. You can use docker-machine with the following command:

docker-machine create -d virtualbox --virtualbox-boot2docker-url https://github.com/boot2docker/boot2docker/releases/download/v1.13.0-rc1/boot2docker.iso <name>

The docker daemon needs to run in swarm mode because PWD uses overlay attachable networks. For that just run docker swarm init.

It's also necessary to manually load the IPVS kernel module because as swarms are created in dind, the daemon won't load it automatically. Run the following command for that purpose: sudo lsmod xt_ipvs

Start the Docker daemon on your machine and run docker pull docker:1.12.2-rc2-dind.

1. Install go 1.7.1 with brew on Mac or through a package manager.

2. go get

3. go build

4. Run the binary produced as play-with-docker

5. Point to http://localhost:3000/ and click "New Instance"

Notes:

• There is a hard-coded limit to 5 Docker playgrounds per session. After 1 hour sessions are deleted.
• If you want to override the DIND version or image then set the environmental variable i.e. DIND_IMAGE=docker:dind

We're planning to setup a reverse proxy that handles redirection automatically, in the meantime you can use ngrok within PWD running docker run --name supergrok -d jpetazzo/supergrok then docker logs --follow supergrok , it will give you a ngrok URL, now you can go to that URL and add the IP+port that you want to connect to… e.g. if your PWD instance is 10.0.42.3, you can go to http://xxxxxx.ngrok.io/10.0.42.3:8000 (where the xxxxxx is given to you in the supergrok logs).
