I am writing a sls template in saltstack and tried to correctly write a cronjob entry but i am not able to do so cause compiler always cries about syntax problem cause it seems the escaping is not working as i thought. i need the escaping backslashes inside the cron command too cause otherwise cronjob does not use the format charackters correctly.
this is the code in my template
{{instance}} cron-entry-for-backup-daily:
cron.present:
- user: root
- name: "{{ online_basedir }}/online_tools/db-tools.py -b {{ settings.port }} -s {{ settings.online_master }} -x {{ instance + '.domain.name' }} backup -d {{ instance }} -f {{ '/opt/onlinebackupdir/' + instance + '/' + instance + '-odoo_db-' + '`date' + '\"' + '+\%Y_\%m_\%d-\%H_\%M' + '\"' + '`' + '_daily.zip'}}"
- minute: '*'
- hour: '22'
- daymonth: '*'
- month: '*'
- dayweek: '1-6'
- identifier: {{ instance + '_dailybackup' }}
- comment: 'Installed via Salt'
the cronjob entry should look like this
* 22 * * 1-6 /opt/online/online_tools/db-tools.py -b 63000 -s xyz123 -x sub.domain.name backup -d dbname -f /opt/onlinebackupdir/dbname/dbname-odoo_db-`date "+\%Y_\%m_\%d-\%H_\%M"`_daily.zip
If i execute this on command line it work if i execute it via cron it works ....
Error message:
i cannot compile my code from the sls file expected , but found '' in "", line 124, column 154: ... ckupdir/dbname/dbname-odoo_db-
date"+\%Y_\%m_\%d-\%H_\%M"_daily.zip"
i already tried some ways but i think i am unable to solve it at the moment to much brain dead already :-( maybe someone knows a solution i also checked the jinja docs for escaping aso ... but i am helpless at the moment
tries:
'`date +\%Y_\%m_\%d-\%H_\%M`' --> error
'`date "+\%Y_\%m_\%d-\%H_\%M"`' --> error
'`date \"+\%Y_\%m_\%d-\%H_\%M\"`' --> error
'`date '+'\%Y_\%m_\%d-\%H_\%M`' --> error
'`date '+\%Y_\%m_\%d-\%H_\%M'`' --> error
'`date \"+"\%Y_\%m_\%d-\%H_\%M"\"'`' --> error
'`date' + '"' + '+\%Y_\%m_\%d-\%H_\%M' + '"' + '`' --> error
'`date' + '"' + '+\%Y_\%m_\%d-\%H_\%M' + '"' + '`' --> error
'`date +%Y_%m_%d-%H%M`' --> compiled and worked in command line but not inside crontab % needs to be escaped
in the meantime i tried this too
"{{ online_basedir }}/online_tools/db-tools.py -b {{ settings.port }} -s {{ settings.online_master_pw }} -x {{ instance + '.domainname.net' }} backup -d {{ instance }} -f {{ '/opt/onlinebackupdir/' + instance + '/' + instance + '-odoo_db-' }} + {% raw %} `date "+\%Y_\%m_\%d-\%H_\%M"` {% endraw %} + {{'_daily.zip'}}"
"{{ online_basedir }}/online_tools/db-tools.py -b {{ settings.port }} -s {{ settings.online_master_pw }} -x {{ instance + '.domainname.net' }} backup -d {{ instance }} -f {{ '/opt/onlinebackupdir/' + instance + '/' + instance + '-odoo_db-' + {% raw %} `date "+\%Y_\%m_\%d-\%H_\%M"` {% endraw %} + '_daily.zip'}}"
This does not work either
OK i solved the Problem with this solution, maybe this is not the best way but it solves my problem....
If someone reads this i would be interested in why {% raw %} .... {% endraw % }
does not work
SOLUTION:
"{{ online_basedir }}/online_tools/db-tools.py -b {{ settings.port }} -s {{ settings.online_master_pw }} -x {{ instance + '.domainname.net' }} backup -d {{ instance }} -f {{ '/opt/onlinebackupdir/' + instance + '/' + instance + '-odoo_db-' + '`date \\\"+\\\\%Y_\\\\%m_\\\\%d-\\\\%H_\\\\%M\\\"`' + '_weekly.zip'}}"
now the line in the crontab looks exactly like i need it:
.......`date "+\%Y_\%m_\%d-\%H_\%M"`..... .zip
RESULT in my BACKUP Folder: instance-odoo_db-2016_10_19-22_00_daily.zip
