## Module functionality
Module creates all required resources for hosting a web service under the ECS.
Resource list:
* target group
* load balancer rules
* ecs service
* ecs task definition
* cloud watch log group
* route53 record (if route53_zone_id variable has been set)

Creation of the ECS task definition is the most tricky thing here. Container definitions are created from templates using internal terraform function.
Default template is template.tmpl. Any other template should be added to module directory.
The module suggest that secrets list will be created outside of the module, so boto3 is our go to.
Also, if task definition changes, it destroy previous one. While deploying you should avoid this issue by deleting old task definition from terraform state before applying new configuration.
