Ask HN: Using Docker for deploying your apps?

Hi guys,

We've built our website and app using a mix of Python and Angular. I'd like to get your experience of embedding these components in a Docker container and deploying images instead. I'm also looking at Docker as a way to deploy an on-premise Saas solution.

What's your experience been like? How is the performance? Are there any concerns or complications I should think about when it comes to scalability?
