# Contributing

email, or any other method with the owners of this repository before making a change. 

Please note we have a code of conduct, please follow it in all your interactions with the project.

## Creating a new runner

To create a new runner you must create a folder named after it that contains a `Dockerfile` and a `docker_init.sh` file. You can use the `r_dev` folder as an example.

Once your container, with all the necessary tools, is built with the `docker_init.sh` script`s (with executable rights). You need to register an account on the [Docker store](https://store.docker.com).

You can now execute the following command to upload your image to the [Docker store](https://store.docker.com). Where `<image_name>` is the name of the image you just built from your `Dockerfile` and `<docker_login>` is the login of your account on the [Docker store](https://store.docker.com).

```sh
docker login
docker tag <image_name> <docker_login>/<image_name>
docker push <docker_login>/<image_name>
```

You then need to create a `\*_runner_register.sh` script similar to the `r_dev_runner_register.sh` script with executable rights. You will need to edit the following arguments:

- `--docker-image <docker_login>/<image_name>`
- `--description "docker runner for <image_name>"`
- `--tag-list "docker, <some other tag identifying your runner>"`

You can now register your runner and test it.


## Pull Request Process

1. Ensure any install or build dependencies are removed before the end of the layer when doing a 
   build.
2. Update the README.md with details of changes to the interface, this includes new environment 
   variables, exposed ports, useful file locations and container parameters.
3. Increase the version numbers in any examples files and the README.md to the new version that this
Pull Request would represent. The versioning scheme we use is [SemVer](http://semver.org/).
4. You may merge the Pull Request in once you have the sign-off of two other developers, or if you do not have permission to do that, you may request the second reviewer to merge it for you.
