Effective DevOps with AWS

Adding a cronjob to our EC2 instance

$ ansible '54.175.86.38' \
      --private-key ~/.ssh/EffectiveDevOpsAWS.pem \
      -m cron -a 'name=ansible-pull minute="*/10" job="/usr/local/bin/ansible-pull -U https://github.com/<your_username>/ansible helloworld.yml -i localhost --sleep 60"'

In the preceding command, we are telling Ansible to use the cron module targeting our ec2 instance. We are providing a name that Ansible will use to track the cronjob over time, telling cron to run the job every 10 minutes, and finally the command to execute and its parameters. ...
