`airflow.providers.amazon.aws.executors.ecs.utils`¶

AWS ECS Executor Utilities.

Data classes and utility functions used by the ECS executor.

Module Contents¶

Classes¶

`EcsQueuedTask`	Represents an ECS task that is queued. The task will be run in the next heartbeat.
`EcsTaskInfo`	Contains information about a currently running ECS task.
`BaseConfigKeys`	Base Implementation of the Config Keys class. Implements iteration for child classes to inherit.
`RunTaskKwargsConfigKeys`	Keys loaded into the config which are valid ECS run_task kwargs.
`AllEcsConfigKeys`	All keys loaded into the config which are related to the ECS Executor.
`EcsExecutorTask`	Data Transfer Object for an ECS Fargate Task.
`EcsTaskCollection`	A five-way dictionary between Airflow task ids, Airflow cmds, ECS ARNs, and ECS task objects.

Functions¶

`parse_assign_public_ip`(assign_public_ip)	Convert "assign_public_ip" from True/False to ENABLE/DISABLE.
`camelize_dict_keys`(nested_dict)	Accept a potentially nested dictionary and recursively convert all keys into camelCase.

Attributes¶

`CommandType`
`ExecutorConfigFunctionType`
`ExecutorConfigType`
`CONFIG_GROUP_NAME`
`CONFIG_DEFAULTS`
