documentation about the build arguments

[k3ck3c]

Hello

I tried to build the image but found no documentation about the values the build arguments should have

I found PKG_TAG could be 3.9 or 3.9.1 from
https://github.com/rspamd/rspamd/tags

but failed to guess any valid value for ASAN_TAG

so the following command failed

docker build -t --build-arg="PKG_TAG=3.9" . 

I guess I miss something very obvious

Thanks for your time

It's recommended to use the already-built image (in FROM if you'd want to extend it). Forking the image on Github and rebuilding there might also be convenient.

Building the image is a 2-step process (currently for no good reason but in the future it will likely be useful again).

0. Image used for builds (ghcr.io/rspamd/rspamd-build-docker:debian-bookworm) is here - building that is straight-forward. To use a different image, Dockerfile.pkg should be modified accordingly.
1. Build the package image: docker build -t rspamd_pkg:3.9.1 --build-arg=RSPAMD_VERSION=3.9.1 --build-arg=RSPAMD_GIT=3.9.1 -f Dockerfile.pkg .
2. Build the productive image using the image built in the previous step: DOCKER_BUILDKIT=1 docker build -t rspamd:3.9.1 --build-arg=PKG_IMG=rspamd_pkg --build-arg=PKG_TAG=3.9.1 .

thanks

the first command went fine, on the second I got

...

but I eventually get an image

rspamd 3.9.1 52e76208fd2a 38 seconds ago 190MB

So I guess this is correct
