Summary

From the log https://github.com/vllm-project/guidellm/actions/runs/18408284407/job/52453702204#step:5:468 , it can be seen that GUIDELLM_BUILD_TYPE=$GUIDELLM_BUILD_TYPE in the container file was not correctly assigned. The reason is that the ARG instructions defined before FROM are global but not available in the build stage context, which can lead to improper version tagging during the build process. This caused the container to use an incorrect version string. Ref to https://docs.docker.com/reference/dockerfile#understand-how-arg-and-from-interact

Details

Moved the ARG GUIDELLM_BUILD_TYPE=dev instruction and its explanatory comments after the FROM $BASE_IMAGE as builder statement. This ensures the build type argument is properly scoped to the build stage.

Test Plan

• In this branch, create a tag such as v0.3.2 and build using buildah build --build-arg GUIDELLM_BUILD_TYPE=release, then check if the logs return the correct version.
