# play-with-docker
|
|
|
|
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/
|
|
|
|
## Requirements
|
|
|
|
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`
|
|
|
|
|
|
## Installation
|
|
|
|
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`
