  - STORAGE_DRIVER_PROPERTY
```
static final String STORAGE_DRIVER_PROPERTY
```
    name of ecs container instance attribute and bamboo server/pbc service system property that denotes what storage driver to pass to the docker-in-docker daemon. With DinD it's important to keep storage drivers in sync for inner and outer daemon. ECS container instance attribute takes precedence if present and is generally recommended.

  - PROPERTY_DIND_OVERRIDE_IMAGES
```
static final String PROPERTY_DIND_OVERRIDE_IMAGES
```
    The versions of Docker in Docker specified in this system property (as a comma separated list, e.g., "docker:1.12-dind,docker:1.11-dind") will be overridden with a newer version that matches the system property below.

    Constant Field Values
  - storage_driver
```
static final String storage_driver
```
    the storage driver used with docker on the ec2 instances in ecs. For docker-in-docker to work we need to use this one in place of the default vfs that is terribly slow.

```
static final String PROPERTY_DRAIN_DISCONNECTED
```
    System property to drain instances with disconnected agents rather than killing the outright. Requires closer observation when set, some instances won't drain on their own ever.
