Capistrano: Finding out who deployed which revision of your application and when
Capistrano automatically logs each (successful) deployment into a file on your application servers.
It is located at the root of your server's project folder, i.e. the parent of
current, like so:
/var/www/your-project$ ls current log releases repo revisions.log <--- here shared
Each line in that file contains the deployed branch, commit, release ID, and username (was read from the deploying user's machine):
$ tail -n3 revisions.log Branch master (at da45511bea63002ac2ff002d1692e09d0dd7cb88) deployed as release 20190716082309 by alice Branch master (at dc9c812d847f1322913149a4a5648d933b6aa73a) deployed as release 20190722141405 by bob Branch master (at 4bb4e2c23a3ed3c7e9c972a8416e109391461af0) deployed as release 20190722144129 by bob
Note that release IDs by default are a formatted deployment timestamp (yyyymmddHHMMSS), so as a bonus you will usually know when that release was deployed.
If your release IDs are different, you can try reading the directory's modification timestamp:
$ stat -c %y releases/0023 2019-07-22 16:43:11.877664481 +0200
FYI: If you are only interested in the currently deployed revision, we also have a card on this. It also contains a Capistrano task that can be called from developer machines.
