| `ECS_SHARED_VOLUME_MATCH_FULL_CONFIG` | `true` | When `true`, ECS Agent will compare name, driver options, and labels to make sure volumes are identical. When `false`, Agent will short circuit shared volume comparison if the names match. This is the default Docker behavior. If a volume is shared across instances, this should be set to `false`. | `false` | `false`|
| `ECS_CONTAINER_INSTANCE_PROPAGATE_TAGS_FROM` | `ec2_instance` | If `ec2_instance` is specified, existing tags defined on the container instance will be registered to Amazon ECS and will be discoverable using the `ListTagsForResource` API. Using this requires that the IAM role associated with the container instance have the `ec2:DescribeTags` action allowed. | `none` | `none` |
| `ECS_CONTAINER_INSTANCE_TAGS` | `{"tag_key": "tag_val"}` | The metadata that you apply to the container instance to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. Tag keys can have a maximum character length of 128 characters, and tag values can have a maximum length of 256 characters. If tags also exist on your container instance that are propagated using the `ECS_CONTAINER_INSTANCE_PROPAGATE_TAGS_FROM` parameter, those tags will be overwritten by the tags specified using `ECS_CONTAINER_INSTANCE_TAGS`. | `{}` | `{}` |
| `ECS_ENABLE_UNTRACKED_IMAGE_CLEANUP` | `true` | Whether to allow the ECS agent to delete containers and images that are not part of ECS tasks. | `false` | `false` |
| `ECS_EXCLUDE_UNTRACKED_IMAGE` | `alpine:latest` | Comma seperated list of `imageName:tag` of images that should not be deleted by the ECS agent if `ECS_ENABLE_UNTRACKED_IMAGE_CLEANUP` is enabled. | | |
