# Purpose {{{
|
|||
|
|
## Create a temp file (to monitor) if an upgrade is available for Sharelatex
|
|||
|
|
## image on the Docker Hub.
|
|||
|
|
## How-to use {{{
|
|||
|
|
### 1. Needs imagetags script, in the same directory
|
|||
|
|
### cf. https://git.ipr.univ-rennes1.fr/cellinfo/scripts/src/master/docker/imagetags
|
|||
|
|
# wget https://git.ipr.univ-rennes1.fr/cellinfo/scripts/raw/master/docker/imagetags
|
|||
|
|
### 2. Ensure to run with a user member of the docker group.
|
|||
|
|
### 3. Create a cron job, eg.
|
|||
|
|
#00 20 * * * root /opt/repos/ipr.scripts/docker/check.sharelatex.update
|
|||
|
|
### 4. Monitor the temp file.
|
|||
|
|
# Or enable MAILTO in cronjob and print a message in the script.
|
|||
|
|
# Or send a mail.
|
|||
|
|
