# This is a dockerfile for building the docker container that can 
# create the documentation. It requires REFPROP and cannot be made 
# publicly available. 
# 
# Normally, a CI workflow should take care of executing the commands 
# to build the docker image. However, you can also use an access 
# token to manually build the new image and push it to github.
#
# To get the token:
# github settings for user -> Developer settings -> Personal access tokens -> Tokens (classic) -> New personal access token (classic) -> tick write:packages -> store in the file your_token
# 
# $ copy the REFPROP sources to the directory of this file.
# $ cat your_token | docker login ghcr.io -u USERNAME --password-stdin
# $ docker build --file docs_02_builder.Dockerfile --tag ghcr.io/coolprop/coolprop_docs_02_builder:dev .
# $ docker push ghcr.io/coolprop/coolprop_docs_02_builder:dev


# Use an intermediate container to build REFPROP
