# Purpose {{{
|
||
## Create a file (to monitor) if an upgrade is available for Ceph
|
||
## project on Github.
|
||
## It's based on .deb package (or repository) installation to check the
|
||
## current version.
|
||
## How-to use {{{
|
||
### 1. Needs releasetags script, in the same directory
|
||
### cf. https://git.ipr.univ-rennes.fr/cellinfo/scripts/src/master/github/releasetags
|
||
# wget https://git.ipr.univ-rennes.fr/cellinfo/scripts/raw/master/github/releasetags
|
||
### 2. Create a cron job, eg :
|
||
#00 20 * * * root /opt/repos/ipr.scripts/github/check_ceph_update
|
||
### 3. Monitor the file : /srv/.github.ceph.upgrade
|
||
# Or enable MAILTO in cronjob and edit the script to print a message.
|
||
# Or send a mail.
|
||
# …
|
||
## }}}
