lets-encrypt-automation

Cloning

This module includes two submodules which need to be installed. The best option is to fetch them during clone git clone --recursive <this repo>

If you already cloned, you can fetch with

  • git submodule init
  • git submodule update

Also make sure to install the python requirements for the cloudflare submodule pip install -r letsencrypt-cloudflare-hook/requirements.txt (if python2.7 use requirements-python-2.txt)

Usage

This single repo is used for all our lets-encrypt cert generation and automation, which means multiple certs being renews at different times.

make.pl produces a script that can be used to create/renew a single certificate.

install.pl takes a script and installs it in crontab.

  • When installing the cron, expects two env vars to be set: CF_EMAIL and CF_KEY
$ ./make.pl static.envoy.com -a dashboard.static.envoy.com -a web.static.envoy.com
$ cat scripts/static.envoy.com-cron.sh
#!/bin/bash
set -x
/Users/chrisb/work/lets-encrypt-automation/letsencrypt.sh/letsencrypt.sh \
  --cron \
  --domain static.envoy.com \
  --domain dashboard.static.envoy.com \
  --domain web.static.envoy.com \
  --challenge dns-01 \
  --hook '/Users/chrisb/work/lets-encrypt-automation/letsencrypt-cloudflare-hook/hook.py'

$ CF_EMAIL=chris@envoy.com CF_KEY=K9uX2HyUjeWg5AhAb sh scripts/static.envoy.com-cron.sh
... [verify output] ...

$ CF_EMAIL=chris@envoy.com CF_KEY=K9uX2HyUjeWg5AhAb ./install.pl scripts/static.envoy.com-cron.sh
Installing crontab. Note that this appends the cron and does not delete old installations.
