docker build broken in golang container since v1.9.2

[tmatth]

Which version are you using?

v1.9.2

Which operating system are you using?

Linux amd64 Docker

Describe how to replicate the issue

I'm assuming this is since #3409, but the build seems to be failing when run in a standard golang docker image.

To reproduce:

docker run -it golang:1.23.2-bullseye bash

curl -fSL http://github.com/aler9/rtsp-simple-server/archive/v1.9.2.tar.gz -o v1.9.2.tar.gz

tar -xzvf v1.9.2.tar.gz

cd mediamtx-1.9.2

go mod download -x

go generate ./...

Hello Tristan, the versiongetter script was introduced to automatically fill the version string inside the server, by using tag data inside the .git folder, an approach used by many other software.

Source code tarballs are automatically generated during every release and they do not include the .git folder nor any other data that might allow to extract the current version. My intention is to drop support for build processes that start from these tarballs. Your approach can be changed into:

FROM golang:1.23.2-bullseye
RUN git clone --depth=1 -b v1.9.2 http://github.com/bluenviron/mediamtx
WORKDIR mediamtx
RUN go generate ./...
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags="-w -s" -v -o /tmp/rtsp-simple-server

Let me know if you have a better solution.

Thanks that works around the issue for me.

Let me know if you have a better solution.

I'd suggest generating/including a VERSION file in release tarballs and just falling back to using git if its missing, this way you don't force a dependency on git for downstream users/packagers.
