This is a simple script to create pdf file with 2 months.
You need to install Docker.
Then you need to build image:
./build
And then start it, specifying the start year and month:
docker run \
--rm \
--env "START_YEAR_MONTH=2015-05" \
--volume `pwd`:/data \
pdf_a4_two_months
And you will get file 2015-05.pdf
