dokku/letsencrypt repository overview

⁠docker-letsencrypt

This is a containerfile for the "simp_le" Let's encrypt implementation by zenhack (https://github.com/zenhack/simp_le⁠). It's running on Alpine Linux and is only around 60MB in size. It was inspired by kuba/simp_le and katta/sim_le but has a couple of improvements.

Certs are saved in /certs so you should mount a persistent volume there.

⁠Simple run

If you only want to get some certificates, simply run the container like this:

docker run -ti -p 80:80 -v /etc/nginx/certs:/certs \
dokku/letsencrypt -f account_key.json -f account_reg.json  \
-f chain.pem -f cert.pem -f key.pem --email [email protected] \
-d adminswerk.de -d test.adminswerk.de

⁠Entrypoint Override

By default the container starts with an entrypoint-script which passes all arguments you start the container with to simp_le.py. If you want to start another application, e.g. for debugging or to build something ontop the container, you have to set the environment variable OVERRIDE. It only needs to be not null, the value doesn't matter.

docker run -ti -p 80:80 -v /etc/nginx/certs:/certs -e "OVERRIDE=1" \
