ansible.builtin.cron – Manage cron.d and crontab entries¶
This module is part of
ansible-base and included in all Ansible
installations. In most cases, you can use the short module name
cron even without specifying the
Despite that, we recommend you use the FQCN for easy linking to the module
documentation and to avoid conflicting with other collections that may have
the same module name.
New in version 0.9: of ansible.builtin
Use this module to manage crontab and environment variables entries. This module allows you to create environment variables and named crontab entries, update, or delete them.
When crontab jobs are managed: the module includes one line with the description of the crontab entry
"#Ansible: <name>"corresponding to the “name” passed to the module, which is used by future ansible/module calls to find/check the state. The “name” parameter should be unique, and changing the “name” value will result in a new cron task being created (or a different one being removed).
When environment variables are managed, no comment line is added, but, when the module needs to find/check the state, it uses the “name” parameter to find the environment variable definition line.
When using symbols such as %, they must be properly escaped.
The below requirements are needed on the host that executes this module.
