Using Transip (lexicon supported) you need to add more lines in opening docker

[2-MAdD]

Standard you need to run the docker like this:

docker run --rm --name dnsrobocert
    --volume /etc/dnsrobocert/config.yml:/etc/dnsrobocert/config.yml
    --volume /etc/letsencrypt:/etc/letsencrypt
    adferrand/dnsrobocert:latest

but if you're using Transip as provider, you need to give the api.key a place in this command, otherwise it wont work:

docker run --rm --name dnsrobocert
    --volume /etc/dnsrobocert/config.yml:/etc/dnsrobocert/config.yml
    --volume /etc/letsencrypt:/etc/letsencrypt
    --volume /etc/dnsrobocert/api.key:/etc/dnsrobocert/api.key
    adferrand/dnsrobocert:3.0.0

This make is for getting the key also known in the docker.

Hello!

Indeed this is a limitation of the Transip provider on Lexicon side, which accepts only a file for the api key. If you have interest for this, could you open an issue on https://github.com/analogj/lexicon so we can extend its possibilities, and avoid to mount a file in the Docker?
