Run a scheduled task on AWS Batch using Ansible and Docker.

Dependencies:

• awscli

Default Configuration:

• Concurrency restricted to one at a time by limiting the resources of the ComputeEnvironment. (Job vCpus: 2 // Default Environment MaxvCpus: 2)
• Ansible Playbook notifies Slack at job start and at job failure/success and sends failure/success notification to Datadog.
• Job names are random. This can be modified in cfn/batch-scheduled-task.template by assigning a static value to job1Name in line 161.
