If you do not want to hardcode the values into the Dockerfile but instead want to set them from your environment, then to make them available to the builder try setting the build args at the command line with the --build-arg option and declaring them in the Dockerfile with ARG:

# in Dockerfile
ARG ENV_VAR1
ARG ENV_VAR2
ENV ENV_VAR1=${ENV_VAR1}
ENV ENV_VAR2=${ENV_VAR2}

# in terminal
$ docker build --build-arg ENV_VAR1=${ENV_VAR1} --build-arg ENV_VAR2=${ENV_VAR2} .
