Added dockerfile

[andrej-s]

Hello, thank you for this great project! I am using tempo inside a Docker container and thought you might be interested in adding this to your repo.

Anyways, thanks again, Agate.

Thank you for this! I have tested locally and it works great. I wanted to add a couple small changes before merging but unfortunately I don't have the permission to edit your branch.

Do you think you could add a .dockerignore file containing node_modules/ and the following section at the end of the README.md?

Deploying using Docker

If you want to deploy Tempo using Docker, you can use our Dockerfile:

docker build -t tempo .
docker run --rm -p 8097:80 tempo

The image includes an Nginx server and a compiled bundle of Tempo assets.

More than happy to do so, @agateblue - one question though: I am not sure adding node_modules to a dockerignore file, as there is no such folder on your repo, and when copying data to the final image, we only copy the build folder - the final image is as sleek as can be. Maybe I am misunderstanding. Just let me know if you'd like me to still add a dockerignore and I'll happily oblige.

Sorry, I should have given more context: in a local/dev environment where you try or work on Tempo with and without docker, node_modules exists and building the image can take a while because this folder is passed into the docker build context ;)

Perfect, makes sense! I followed both your suggestions.

Perfect, thanks again for your help on this :)
