Alpine Linux simp_le Docker container
This is a containerfile for the "simp_le" Let's encrypt implementation by kuba (https://github.com/kuba/simp_le). It's running on Alpine Linux and is only around 60MB in size.
It was inspired by
katta/sim_le but has a couple of improvements.
Certs are saved in
/certs so you should mount a persistent volume there.
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 \ m3adow/letsencrypt-simp_le -f account_key.json \ -f chain.pem -f cert.pem -f key.pem --email firstname.lastname@example.org \ -d adminswerk.de -d test.adminswerk.de
simp_le is refreshed from the repos master branch at container start. This normally takes not more than one second and ensures it's always up to date. If you want to disable this functionality, start the container with the environment variable
SKIP_REFRESH set. It doesn't matter which value it contains as long as it's not null.
docker run -ti -p 80:80 -v /etc/nginx/certs:/certs -e "SKIP_REFRESH=1" \ m3adow/letsencrypt-simp_le -f account_key.json -f chain.pem \ -f cert.pem -f key.pem --email email@example.com -d adminswerk.de
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. Identical to
SKIP_REFRESH, it only needs to be not null, the value doesn't matter.
SKIP_REFRESH (but not the other way around), so no need to define both envs.
docker run -ti -p 80:80 -v /etc/nginx/certs:/certs -e "OVERRIDE=1" \ m3adow/letsencrypt-simp_le sh
