dostuffonline.com is a simple site that hosts a wide range of tools - things like file conversions, video transcription, network testing tools, and so on. Anything for which you'd google "${to task} online" and hope to find some small utility.
This app is overengineered on purpose. Each tool will be its own microservice called by the frontend. This gives be an excuse to run a kubernetes cluster.
Each service has a deploy.sh in it's /services/${service} directory. That script will build and launch each service as a local docker container. You can run them all at once with /scripts/launch-all.sh.
