A simple command to install a cron table.

Project description

Latest PyPI version travis

A simple command to install a cron table, and make it evolve over time.

logo

Use it in a deployement task to deploy a file containing your crontab.

Usage

Call the command using the module name.

Indicate a marker, unique on the host, with -m option, that will help identify the start / end of your specific tasks in crontab.

Indicate a file containing your crontab. The file may reference environment variables, that will be replaced at installation time using the python builtin template module.

For example, if we have a file crontab.tpl containing:

MAILTO="$ADMIN_MAIL"
# recompute the model
0 0 * * * python -m project.rebuild_model >>/dev/null
# check stuff in $STUFF_DIRNAME
*/10 * * * /usr/local/bin/check_stuff $STUFF_DIRNAME >>/dev/null

Launching:

$ ADMIN_MAIL="admin@acme.info" STUFF_DIRNAME="/srv/stuff" python3 -m cron_install -m MY_PROJECT crontab.tpl

Will install the following table:

$ crontab -l
# START MY_PROJECT
MAILTO="admin@acme.info"
# recompute the model
0 0 * * * python -m project.rebuild_model >>/dev/null
# check stuff in /srv/stuff
*/10 * * * /usr/local/bin/check_stuff /srv/stuff >>/dev/null
# END MY_PROJECT

On a new run, all the part between # START MY_PROJECT and # END MY_PROJECT, will be replaced by the new crontab.
