This is a Reeve step for loading runtime variables from a .env file.
See the environment variables mentioned in Dockerfile.
Params starting with ENV_
specify which variables to load and how they should be named.
E.g. the following loads the variable REEVE_VERSION
from the file .env
and stores the value in the runtime variable IMAGE_VERSION
.
FILE: .env
ENV_REEVE_VERSION: IMAGE_VERSION
