Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
--debug
(boolean)
Turn on debug logging.
--endpoint-url
(string)
Override command's default URL with the given URL.
--no-verify-ssl
(boolean)
By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

maxSwap -> (integer)
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the
--memory-swap
option to docker run where the value is the sum of the container memory plus themaxSwap
value. For more information, see `--memory-swap
details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.If a
maxSwap
value of0
is specified, the container doesn't use swap. Accepted values are0
or any positive integer. If themaxSwap
parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. AmaxSwap
value must be set for theswappiness
parameter to be used.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.swappiness -> (integer)
You can use this parameter to tune a container's memory swappiness behavior. A
swappiness
value of0
causes swapping to not occur unless absolutely necessary. Aswappiness
value of100
causes pages to be swapped aggressively. Valid values are whole numbers between0
and100
. If theswappiness
parameter isn't specified, a default value of60
is used. If a value isn't specified formaxSwap
, then this parameter is ignored. IfmaxSwap
is set to 0, the container doesn't use swap. This parameter maps to the--memory-swappiness
option to docker run .Consider the following when you use a per-container swap configuration.
- Swap space must be enabled and allocated on the container instance for the containers to use.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
- The swap space parameters are only supported for job definitions using EC2 resources.
- If the
maxSwap
andswappiness
parameters are omitted from a job definition, each container has a defaultswappiness
value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.logConfiguration -> (structure)
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 might 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, alternatively, it must be configured on a different log server for remote logging options. For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.Note
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers might 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 | grep "Server API version"
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with theECS_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 .logDriver -> (string)

, andsplunk
.Note
Jobs that are running on Fargate resources are restricted to the
awslogs
andsplunk
log drivers.awslogs
Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs log driver in the Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.
fluentdSpecifies the Fluentd logging driver. For more information including usage and options, see Fluentd logging driver in the Docker documentation .
gelfSpecifies the Graylog Extended Format (GELF) logging driver. For more information including usage and options, see Graylog Extended Format logging driver in the Docker documentation .

Note
If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.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:

The Batch Scheduler checks the compute environments that are attached to the job queue before registering a task definition with Fargate. In this scenario, the job queue is where the job is submitted. If the job requires a Windows container and the first compute environment isLINUX
, the compute environment is skipped and the next compute environment is checked until a Windows-based compute environment is found.Note
Fargate Spot is not supported forARM64
and Windows-based containers on Fargate. A job queue will be blocked if a FargateARM64
or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach bothFARGATE

maxSwap -> (integer)
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the
--memory-swap
option to docker run where the value is the sum of the container memory plus themaxSwap
value. For more information, see `--memory-swap
details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.If a
maxSwap
value of0
is specified, the container doesn't use swap. Accepted values are0
or any positive integer. If themaxSwap
parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. AmaxSwap
value must be set for theswappiness
parameter to be used.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.swappiness -> (integer)
You can use this parameter to tune a container's memory swappiness behavior. A

causes swapping to not occur unless absolutely necessary. Aswappiness
value of100
causes pages to be swapped aggressively. Valid values are whole numbers between0
and100
. If theswappiness
parameter isn't specified, a default value of60
is used. If a value isn't specified formaxSwap
, then this parameter is ignored. IfmaxSwap
is set to 0, the container doesn't use swap. This parameter maps to the--memory-swappiness
option to docker run .Consider the following when you use a per-container swap configuration.
- Swap space must be enabled and allocated on the container instance for the containers to use.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
- The swap space parameters are only supported for job definitions using EC2 resources.
- If the
maxSwap
andswappiness
parameters are omitted from a job definition, each container has a defaultswappiness

maxSwap -> (integer)
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the
--memory-swap
option to docker run where the value is the sum of the container memory plus themaxSwap
value. For more information, see `--memory-swap
details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.If a
maxSwap
value of0
is specified, the container doesn't use swap. Accepted values are0
or any positive integer. If themaxSwap
parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. AmaxSwap

value of100
causes pages to be swapped aggressively. Valid values are whole numbers between0
and100
. If theswappiness
parameter isn't specified, a default value of60
is used. If a value isn't specified formaxSwap
, then this parameter is ignored. IfmaxSwap
is set to 0, the container doesn't use swap. This parameter maps to the--memory-swappiness
option to docker run .Consider the following when you use a per-container swap configuration.
- Swap space must be enabled and allocated on the container instance for the containers to use.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
- The swap space parameters are only supported for job definitions using EC2 resources.
- If the
maxSwap
andswappiness
parameters are omitted from a job definition, each container has a defaultswappiness

This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.logConfiguration -> (structure)
The log configuration specification for the container.
This parameter maps to
LogConfig

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 .
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in theLogConfiguration
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}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with theECS_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 .logDriver -> (string)
