It's something else to learn. Learning takes time and distracts you from building your product. My backend is an Express app. Locally I just run with it Node.

It's something else to learn. Learning takes time and distracts you from building your product. My backend is an Express app. Locally I just run with it Node. In production, I let Heroku run it. I also use AWS Lambda functions and Cloudflare Workers, neither of which use Docker. I have no need to introduce Docker into my workflow.
