ACERTMGR

This is an automated certificate manager using ACME/letsencrypt.

Running ACERTMGR

The main file acertmgr.py is intended to be run regularly (e.g. as daily cron job) as root.

Requirements

Python (2.7+ and 3.4+ should work) PyYAML acme_tiny (acme_tiny.py placed in /opt/acme/acme_tiny.py)

Configuration

The main configuration is read from /etc/acme/acme.conf, domains for which certificates should be obtained/renewed should be configured in /etc/acme/domains.d/{fqdn}.conf.

All configuration files use yaml syntax.

• Example global configuration file:

---

mode: webdir
#mode: standalone
webdir: /var/www/acme-challenge/

defaults:
  format: split

• Example domain configuration file:

---

mail.example.com:
- user: postfix
  group: postfix
  perm: '400'
  notify: '/etc/init.d/postfix reload'
- user: dovecot
  group: dovecot
  perm: '400'
  notify: '/etc/init.d/dovecot reload'

Security

Please keep the following in mind when using this software:

• DO read the source code, since it is intended to be run as root
• Make sure that your configuration files are NOT writable by other users - arbitrary commands can be executed after updating certificates
