01/20/2022, 4:40 PMHi, I have a question about DockerStorage I did not manage to figure out on my own. I would like to pass a variable to the docker build so that it is replaced inside the docker file. It seems the env_vars in the DockerStore are not the right place. Any hints on how to do this?

Why is env_vars not the right place? What happens when you set it there?

What do you think of extra_dockerfile_commands?

The code example here shows what it would look like. Maybe just use the Docker
ENVf

01/20/2022, 6:57 PMOkay I found the way to do it. I needed to add the the variable explicitly via ARG in the docker file and then pass it via
storage = Docker(dockerfile=str(project_path/"Dockerfile"), prefect_directory="/tmp/prefect", build_kwargs={"buildargs":{"PROJECT_PATH":"projects/path/"}})k
