Method Details

getImage
The image used to start a container.This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either
repository-url/image:tag
orrepository-url/image@digest
. Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps toImage
in the Create a container section of the Docker Remote API and theIMAGE
parameter of the docker run .- See Also:
-
getCommand
The command that's passed to the container.This parameter maps to
Cmd
in the Create a container section of the Docker Remote API and theCOMMAND
parameter to docker run . For more information, see Dockerfile reference: CMD .- See Also:
-
getDependsOn
A list of containers that this container depends on.- See Also:
-
getEnvironment
The environment variables to pass to a container.This parameter maps to Env inthe Create a container section of the Docker Remote API and the
--env
parameter to docker run .We don't recommend using plaintext environment variables for sensitive information, such as credential data. > Environment variables cannot start with
AWS_BATCH
. This naming convention is reserved for variables that AWS Batch sets.- See Also:
-
getEssential
If the essential parameter of a container is marked astrue
, and that container fails or stops for any reason, all other containers that are part of the task are stopped.If the
essential
parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.All jobs must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
- See Also:
-
getLinuxParameters
Linux-specific modifications that are applied to the container, such as Linux kernel capabilities.For more information, see KernelCapabilities .
- See Also:
-
getLogConfiguration
The log configuration specification for the container.This parameter maps to
LogConfig
in the Create a container section of the Docker Remote API and the--log-driver
option to docker run .By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation .
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the
LogConfiguration
data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version
--format '{{.Server.APIVersion}}'
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the
ECS_AVAILABLE_LOGGING_DRIVERS
environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .- See Also:
-
getMountPoints
The mount points for data volumes in your container.This parameter maps to
Volumes
in the Create a container section of the Docker Remote API and the --volume option to docker run .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.- See Also:
-
getName
The name of a container.The name can be used as a unique identifier to target your
dependsOn
andOverrides
objects.- See Also:
-
getPrivileged
When this parameter istrue
, the container is given elevated privileges on the host container instance (similar to theroot
user).This parameter maps to
Privileged
in the Create a container section of the Docker Remote API and the--privileged
option to docker run .This parameter is not supported for Windows containers or tasks run on Fargate.
- See Also:
-
getReadonlyRootFilesystem
When this parameter is true, the container is given read-only access to its root file system.This parameter maps to
ReadonlyRootfs
in the Create a container section of the Docker Remote API and the--read-only
option to docker run .This parameter is not supported for Windows containers.
- See Also:
-
getRepositoryCredentials
The private repository authentication credentials to use.- See Also:
-
getResourceRequirements
The type and amount of a resource to assign to a container.The only supported resource is a GPU.
- See Also:
-
getSecrets
The secrets to pass to the container.For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.
- See Also:
-
getUlimits
A list ofulimits
to set in the container.If a
ulimit
value is specified in a task definition, it overrides the default values set by Docker. This parameter maps toUlimits
in the Create a container section of the Docker Remote API and the--ulimit
option to docker run .Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The
nofile
resource limit sets a restriction on the number of open files that a container can use. The defaultnofile
soft limit is1024
and the default hard limit is65535
.This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version
--format '{{.Server.APIVersion}}'
This parameter is not supported for Windows containers.
- See Also:
-
getUser
The user to use inside the container.This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run.
When running tasks using the
host
network mode, don't run containers using theroot user (UID 0)
. We recommend using a non-root user for better security.You can specify the
user
using the following formats. If specifying a UID or GID, you must specify it as a positive integer.user
user:group
uid
uid:gid
user:gi
uid:group
This parameter is not supported for Windows containers.
