[usability] The node.js image is fairly huge

markusthoemmes/node                                    latest                         42399af4329d        40 years ago        322MB

That's quiiiite big if the alpine-nodejs image on Dockerhub is just 26meg. Smaller images should make for a quicker push/deploy iteration cycle, even when starting.

@markusthoemmes don't we have to base our images on ubi-8 (or something that is under RH control)?

[lance]

@markusthoemmes I totally agree! But it is based on ubi8-minimal with only Node.js and the source code added. But 322MB still seems quite large and doesn't really add up

The ubi8-minimal image itself is 142MB and the Buildpack stack images based on it are 165MB. The installed size of Node.js is around 30MB. That should bring the faas-stack-run image size to 195MB. But looking at it now, it's showing 291MB. I'll have to dig a bit to better understand why it's not closer to the quarkus native image, for example.

FWIW I was just in a meeting last week with the RHEL folks and they are aware that ubi8-minimal is not really that minimal, and I believe there are some hazy plans around improving this. That still doesn't explain why the Node.js image is quite so big. But FYI.

[lance]

A bit confused about what's going on here. As you can see from the log, we're building the run image based on faas-stack-run:ubi8-minimal. Which is 165MB. Later in the log, you can see that I'm installing Node.js (should change to not install docs), and the total install size is about 27MB. So the final image should definitely be under 200MB. But the final size of the run image is > 300MB. Why is this?
