- Do: Use the Docker logo to show your service is using Docker or is compatible with Docker
- Do: Scale the Docker logo proportionally (without changing the aspect ratio) as you see fit
- Do not: Show the Docker logo larger than your own logo
- Use the word Docker as the first word in the name of your website or domain name, application or product, business name, social media and other online accounts, including Twitter, Facebook, or GitHub
- Other things to know: the D in Docker, Dockerfile, Docker Swarm and other marks consisting of "Docker", except when you are specifically referring to the commandline command, for example for 'docker run'. Then you may use 'docker'.
- Do not: Use the Docker logo or a modification or variation in an avatar or as a profile image for social media accounts or other online accounts.

The Docker image here is supposed to reproduce lxplus as good as possible, such that it can be used in continuous integration tests, which … well test if your project works on lxplus.
