Title. Just wondering if I did something bad/terrible with it. Link is @ title. Check the image tag @ its repo to see how it was built. And before someone asks… the Docker lemmy community is really dead so I had to resort to you guys. Sorry, I guess.
And thanks in advance.
A bit late but you might want to have a look at docker multi-stage build documentation which does exactly what you did (start from a base image then copying stuff from it to your own image), something like that:
FROM someimage:sometag AS build [do stuff] FROM minimalimage:someothertag COPY --from=build /some/file /some/other/file [and so on] USER somebody CMD ["/path/somecommand"]Which will simplify building new images against newer “build” image newer tags easier.
btw, you were quite creative on this one! You also might want to have a look at the distroless image, the goal being to only have the bare minimum to run your application in the image: your executable and its runtime dependencies.
Now you’ve confused me a little bit – is there any difference between a scratch and a distroless image? Aren’t they (technically) the same thing?
That aside, thank you for your input and compliment.
You’re welcome! scratch and distroless are indeed basically the same thing, scratch being the ‘official’ docker minimal image while distroless is from google - as I’m more a Kubernetes user (at home and at work) than a Docker user, I tend to think about distroless first :) - my apologies if my comment was a bit confusing on this matter.
By the way, have fun experimenting with docker (or podman), it’s interesting, widely used both in selfhosting and professional environments, and it’s a great learning experience - and a good way to pass time during these long winter evenings :)
