apache-certbot

Docker Container to generate / renew https certificates from letsencrypt using apache2 and certbot

Description

Once setup, just run sudo docker-compose up and all your letsencrypt certificates get renewed.

They will be stored in ./letsencrypt and can be mounted as readonly into any other docker container with:

# docker-compose.yml
# services:
#  serviceOne
# ...
    volumes:
     - <path-to-apache-certbot>/letsencrypt:/etc/letsencrypt:ro
# ...

Setup

Edit docker-compose.yml and replace EMAIL with your email for letsencrypt aswell as DOMAINS with a comma- separated list of all domains you want to generate a certificate for.

Run it

If there are other services/containers running on port 80, stop them.

sudo docker-compose build && sudo docker-compose up

Then start any stopped services/containers again.

Run it fully automated every week

If you add docker-compose up to your crontab for weekly execution, it may cause problems if there are other services/containers listening on port 80 which is required for the renewal.

Therefore you can use the autoRenewCertificates script which is an example of how to to first stop conflicting docker containers and then start them again after renewal.

Simply edit autoRenewCertificates and adjust stop() and start() depending on the docker containers to be stopped during certificate renewal. Also don't forget to adjust the location of your copy of this repo in line 5.

Then run

sudo EDITOR=nano crontab -e

and add the following two lines

# run weekly at 05:30am
30 5 * * 1 <path-to-apache-certbot-folder>/autoRenewCertificates
