Volume
The data volume configuration for tasks launched using this task definition.
Specifying a volume configuration in a task definition is optional. The volume
configuration may contain multiple volumes but only one volume configured at launch is
supported. Each volume defined in the volume configuration may only specify a
name
and one of either configuredAtLaunch
,
dockerVolumeConfiguration
, efsVolumeConfiguration
,
fsxWindowsFileServerVolumeConfiguration
, or host
. If an
empty volume configuration is specified, by default Amazon ECS uses a host volume. For more
information, see Using data volumes in
tasks.
Contents
- configuredAtLaunch
-
Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.
To configure a volume at launch time, use this task definition revision and specify a
volumeConfigurations
object when calling theCreateService
,UpdateService
,RunTask
orStartTask
APIs.Type: Boolean
Required: No
- dockerVolumeConfiguration
-
This parameter is specified when you use Docker volumes.
Windows containers only support the use of the
local
driver. To use bind mounts, specify thehost
parameter instead.Note
Docker volumes aren't supported by tasks run on AWS Fargate.
Type: DockerVolumeConfiguration object
Required: No
- efsVolumeConfiguration
-
This parameter is specified when you use an Amazon Elastic File System file system for task storage.
Type: EFSVolumeConfiguration object
Required: No
- fsxWindowsFileServerVolumeConfiguration
-
This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.
Type: FSxWindowsFileServerVolumeConfiguration object
Required: No
- host
-
This parameter is specified when you use bind mount host volumes. The contents of the
host
parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If thehost
parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.Windows containers can mount whole directories on the same drive as
$env:ProgramData
. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mountC:\my\path:C:\my\path
andD:\:D:\
, but notD:\my\path:C:\my\path
orD:\:C:\my\path
.Type: HostVolumeProperties object
Required: No
- name
-
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the
name
is required and must also be specified as the volume name in theServiceVolumeConfiguration
orTaskVolumeConfiguration
parameter when creating your service or standalone task.For all other types of volumes, this name is referenced in the
sourceVolume
parameter of themountPoints
object in the container definition.When a volume is using the
efsVolumeConfiguration
, the name is required.Type: String
Required: No
