Lists expiration time of soon-to-be expired ssl certificates of all given domains like:
./certificate_watcher.py mdk.fr python.org duckduckgo.com mdk.fr expire in 2 days
The list of domains can be given as a file, using the -f or
--from-file argument. In this file, list each domains, one per
line. Blank lines and lines starting with '#' are ignored.
An optional port can be given using the usual syntax host:port, for
example imap.protonmail.com:443.
An optional IP address can be given using an @, this is usefull to
poke multiple backends like:
./certificate_watcher.py example.com@10.1.0.1 example.com@10.1.0.2
A domain to be resolved can be used in this field to, like:
./certificate_watcher.py example.com@backend1.example.com example.com@backend2.example.com
The @host and :port have no specific order, both
example.com:443@127.0.0.1 and example.com@127.0.0.1:443 mean the
same test.
Exemple domain file:
# Our project
example.com
www.example.com
mail.example.com
dev.example.com
demo.example.com
testing.example.com
git.example.com
# Friends
duckduckgo.com
mamot.fr
protonmail.com
# IMAP
imap.protonmail.com:993
Usefull as a daily cron, typically like this:
certificate_watcher -f /home/you/.certificate_watcher
Or if you use IRC:
certificate_watcher -f /home/you/.certificate_watcher | irk '#your_project_channel' -
