Apparently not cause it’s super easy to find. Searching “docker” on Google returned it as the top result for me. it’s a container platform. You have code and it needs somewhere to run. That could be on your computer but that’s ineffective at handling package conflicts. So you run it in a container. This means you can install the specific versions of dependencies that the code needs and you’re least likely to run into conflicts. You can also run multiple instances of a program regardless of whether it would allow it because each instance runs in its own container. Blissfully unaware of the others
