local-crontab-ansible-filter

Ansible filter with a few tools to handle with crontab string. Those tools are:

1. aws_standard_cron
2. standard_aws_cron
3. aws_local_aws_utc_crons
4. standard_local_utc_crons
5. standard_local_utc_cron

Probably the filter will be only compatible with Python3.8 runtime due to dependecies.

Examples

standard_aws_cron

1. Add current year:

   '10 10 * 10 2' | standard_aws_cron

   '10 10 * 10 2 2021' # result

2. Add year and convert '*' in '?' in the right position, from aws_specific_details structure

      aws_specific_details:
         year: 2022
         question_parts: [ 'day' ] # minute, hours, day, etc..
   
      '10 10 * 10 2' | standard_aws_cron(aws_specific_details)

      '10 10 ? 10 2 2022' # result

aws_local_aws_utc_crons

'39 05 * * ? *' | aws_local_aws_utc_crons('Europe/Rome')

# result
[
    "39 4 * 1-2 * *",
    "39 4 1-27 3 ? *",
    "39 3 28-31 3 ? *",
    "39 3 * 4-9 * *",
    "39 3 1-30 10 ? *",
    "39 4 31 10 ? *",
    "39 4 * 11-12 * *"
]

standard_local_utc_cron

'39 1 5 * *' | standard_local_utc_cron('Europe/Rome')

"39 23 4 * *" # result

More examples in filter-example.yaml file.

Test filters

Look at the ansible playbook in the root project and run it! I have made my tests with Ansible 2.9.
