#308 [ImageBuilder] Add project_install_mode arg to Poetry layer in Image spec Pull request opened by popojk ## Issue Referencing to UV project, we should add a

project_install_mode

which is either "dependencies_only" or "install_project". The arg will be defaulted to "dependencies_only" so that poetry will be installed with

--no-root

arg, which tells poetry only install dependencies, otherwise it will also install the project. ## Changes Local docker builder and remote docker builder ## Tests Use this script to run task. The poetry

project_install_mode

config in Image spec is set to "dependencies_only". We expect that poetry will install with

--no-root

mode.
