Your Amazon ECS container instances require at least version 1.26.0 of the container agent to use container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-update.html) in the Amazon Elastic Container Service Developer Guide. If you’re using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init. For more information, see Amazon ECS-optimized Linux AMI (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-optimized_AMI.html) in the Amazon Elastic Container Service Developer Guide.

For tasks that use the Fargate launch type, the task or service requires the following platforms:

• Linux platform version 1.3.0 or later.

• Windows platform version 1.0.0 or later.

For more information about how to create a container dependency, see Container dependency (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/example_task_definitions.html#example_task_definition-containerdependency) in the Amazon Elastic Container Service Developer Guide. || containerDefinitions.[].dependsOn.[].condition

Optional | string
| | containerDefinitions.[].environment.[].value
Optional | string
| | containerDefinitions.[].environmentFiles
Optional | array
| | containerDefinitions.[].environmentFiles.[]
Required | object
A list of files containing the environment variables to pass to a container. You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file should contain an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored.

If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they’re processed from the top down. We recommend that you use unique variable names. For more information, see Specifying environment variables (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/taskdef-envfiles.html) in the Amazon Elastic Container Service Developer Guide.

You must use the following platforms for the Fargate launch type:

• Linux platform version 1.4.0 or later.

• Windows platform version 1.0.0 or later.

Consider the following when using the Fargate launch type:

• The file is handled like a native Docker env-file.

• There is no support for shell escape handling.

• The container entry point interperts the VARIABLE values. || containerDefinitions.[].environmentFiles.[].type

  Optional | boolean
  | | containerDefinitions.[].extraHosts

  Optional | string
  | | containerDefinitions.[].extraHosts.[].ipAddress
  Optional | string
  | | containerDefinitions.[].firelensConfiguration
  Optional | object
  The FireLens configuration for the container. This is used to specify and
  configure a log router for container logs. For more information, see Custom
  log routing (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/using_firelens.html)
  in the Amazon Elastic Container Service Developer Guide. | | containerDefinitions.[].firelensConfiguration.options
  Optional | object
  | | containerDefinitions.[].firelensConfiguration.type
  Optional | string
  | | containerDefinitions.[].healthCheck
  Optional | object
  An object representing a container health check. Health check parameters
  that are specified in a container definition override any Docker health checks
  that exist in the container image (such as those specified in a parent image
  or from the image’s Dockerfile). This configuration maps to the HEALTHCHECK
  parameter of docker run (https://docs.docker.com/engine/reference/run/).
  
  The Amazon ECS container agent only monitors and reports on the health checks
  specified in the task definition. Amazon ECS does not monitor Docker health
  checks that are embedded in a container image and not specified in the container
  definition. Health check parameters that are specified in a container definition
  override any Docker health checks that exist in the container image.
  
  You can view the health status of both individual containers and a task with
  the DescribeTasks API operation or when viewing the task details in the console.
  
  The health check is designed to make sure that your containers survive agent
  restarts, upgrades, or temporary unavailability.
  
  The following describes the possible healthStatus values for a container:
  
  * HEALTHY-The container health check has passed successfully.
  
  * UNHEALTHY-The container health check has failed.
  
  * UNKNOWN-The container health check is being evaluated, there’s no container
  health check defined, or Amazon ECS doesn’t have the health status of
  the container.
  
  The following describes the possible healthStatus values based on the container
  health checker status of essential containers in the task with the following
  priority order (high to low):
  
  * UNHEALTHY-One or more essential containers have failed their health
  check.
  
  * UNKNOWN-Any essential container running within the task is in an UNKNOWN
  state and no other essential containers have an UNHEALTHY state.
  
  * HEALTHY-All essential containers within the task have passed their health
  checks.
  
  Consider the following task health example with 2 containers.
  
  * If Container1 is UNHEALTHY and Container2 is UNKNOWN, the task health
  is UNHEALTHY.
  
  * If Container1 is UNHEALTHY and Container2 is HEALTHY, the task health
  is UNHEALTHY.
  
  * If Container1 is HEALTHY and Container2 is UNKNOWN, the task health
  is UNKNOWN.
  
  * If Container1 is HEALTHY and Container2 is HEALTHY, the task health
  is HEALTHY.
  
  Consider the following task health example with 3 containers.
  
  * If Container1 is UNHEALTHY and Container2 is UNKNOWN, and Container3
  is UNKNOWN, the task health is UNHEALTHY.
  
  * If Container1 is UNHEALTHY and Container2 is UNKNOWN, and Container3
  is HEALTHY, the task health is UNHEALTHY.
  
  * If Container1 is UNHEALTHY and Container2 is HEALTHY, and Container3
  is HEALTHY, the task health is UNHEALTHY.
  
  * If Container1 is HEALTHY and Container2 is UNKNOWN, and Container3 is
  HEALTHY, the task health is UNKNOWN.
  
  * If Container1 is HEALTHY and Container2 is UNKNOWN, and Container3 is
  UNKNOWN, the task health is UNKNOWN.
  
  * If Container1 is HEALTHY and Container2 is HEALTHY, and Container3 is
  HEALTHY, the task health is HEALTHY.
  
  If a task is run manually, and not as part of a service, the task will continue
  its lifecycle regardless of its health status. For tasks that are part of
  a service, if the task reports as unhealthy then the task will be stopped
  and the service scheduler will replace it.
  
  The following are notes about container health check support:
  
  * When the Amazon ECS agent cannot connect to the Amazon ECS service,
  the service reports the container as UNHEALTHY.
  
  * The health check statuses are the “last heard from” response from the
  Amazon ECS agent. There are no assumptions made about the status of the
  container health checks.
  
  * Container health checks require version 1.17.0 or greater of the Amazon
  ECS container agent. For more information, see Updating the Amazon ECS
  container agent (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-update.html).
  
  * Container health checks are supported for Fargate tasks if you’re using
  platform version 1.1.0 or greater. For more information, see Fargate platform
  versions (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/platform_versions.html).
  
  * Container health checks aren’t supported for tasks that are part of
  a service that’s configured to use a Classic Load Balancer. | | containerDefinitions.[].healthCheck.command

  the default capabilities and the non-default available capabilities, see
  Runtime privilege and Linux capabilities (https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities)
  in the Docker run reference. For more detailed information about these Linux

  | | containerDefinitions.[].linuxParameters.tmpfs.[].mountOptions.[]
  Required | string
  || containerDefinitions.[].linuxParameters.tmpfs.[].size
  Optional | integer
  | | containerDefinitions.[].logConfiguration
  Optional | object
  The log configuration for the container. This parameter maps to LogConfig
  in the Create a container (https://docs.docker.com/engine/api/v1.35/#operation/ContainerCreate)
  section of the Docker Remote API (https://docs.docker.com/engine/api/v1.35/)
  and the –log-driver option to docker run (https://docs.docker.com/engine/reference/commandline/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 configuration in the container definition.
  For more information about the options for different supported log drivers,
  see Configure logging drivers (https://docs.docker.com/engine/admin/logging/overview/)
  in the Docker documentation.
  
  Understand the following when specifying a log configuration for your containers.
  
  * Amazon ECS currently supports a subset of the logging drivers available
  to the Docker daemon. Additional log drivers may be available in future
  releases of the Amazon ECS container agent. For tasks on Fargate, the
  supported log drivers are awslogs, splunk, and awsfirelens. For tasks
  hosted on Amazon EC2 instances, the supported log drivers are awslogs,
  fluentd, gelf, json-file, journald, logentries,syslog, splunk, and awsfirelens.
  
  * This parameter requires version 1.18 of the Docker Remote API or greater
  on your container instance.
  
  * For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container
  agent must register the available logging drivers 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 (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-agent-config.html)
  in the Amazon Elastic Container Service Developer Guide.
  
  * For tasks that are on Fargate, because you don’t have access to the
  underlying infrastructure your tasks are hosted on, any additional software
  needed must be installed outside of the task. For example, the Fluentd
  output aggregators or a remote host running Logstash to send Gelf logs
  to. | | containerDefinitions.[].logConfiguration.logDriver
  Optional | string
  | | containerDefinitions.[].logConfiguration.options
  Optional | object
  | | containerDefinitions.[].logConfiguration.secretOptions
  Optional | array
  | | containerDefinitions.[].logConfiguration.secretOptions.[]
  Required | object
  An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:

• To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.

• To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.

For more information, see Specifying sensitive data (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/specifying-sensitive-data.html) in the Amazon Elastic Container Service Developer Guide. || containerDefinitions.[].logConfiguration.secretOptions.[].name
Optional | string
| | containerDefinitions.[].logConfiguration.secretOptions.[].valueFrom
Optional | string
| | containerDefinitions.[].memory
Optional | integer
| | containerDefinitions.[].memoryReservation
Optional | integer
| | containerDefinitions.[].mountPoints
Optional | array
| | containerDefinitions.[].mountPoints.[]
Required | object
The details for a volume mount point that’s used in a container definition. || containerDefinitions.[].mountPoints.[].containerPath
Optional | string
| | containerDefinitions.[].mountPoints.[].readOnly
Optional | boolean
| | containerDefinitions.[].mountPoints.[].sourceVolume
Optional | string
| | containerDefinitions.[].name
Optional | string
| | containerDefinitions.[].portMappings
Optional | array
| | containerDefinitions.[].portMappings.[]
Required | object
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.

If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort. The hostPort can be left blank or it must be the same value as the containerPort.

Most fields of this parameter (containerPort, hostPort, protocol) maps to PortBindings in the Create a container (https://docs.docker.com/engine/api/v1.35/#operation/ContainerCreate) section of the Docker Remote API (https://docs.docker.com/engine/api/v1.35/) and the –publish option to docker run (https://docs.docker.com/engine/reference/commandline/run/). If the network mode of a task definition is set to host, host ports must either be undefined or match the container port in the port mapping.

You can’t expose the same container port for multiple protocols. If you attempt this, an error is returned.

After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses. || containerDefinitions.[].portMappings.[].appProtocol

The repository credentials for private registry authentication. | | containerDefinitions.[].repositoryCredentials.credentialsParameter
Optional | string
| | containerDefinitions.[].resourceRequirements
Optional | array
| | containerDefinitions.[].resourceRequirements.[]
Required | object
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-gpu.html) or Working with Amazon Elastic Inference on Amazon ECS (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-inference.html) in the Amazon Elastic Container Service Developer Guide || containerDefinitions.[].resourceRequirements.[].type
Optional | string
| | containerDefinitions.[].resourceRequirements.[].value
Optional | string
| | containerDefinitions.[].secrets
Optional | array
| | containerDefinitions.[].secrets.[]
Required | object
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:

• To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.

• To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.

For more information, see Specifying sensitive data (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/specifying-sensitive-data.html) in the Amazon Elastic Container Service Developer Guide. || containerDefinitions.[].secrets.[].name
Optional | string
| | containerDefinitions.[].secrets.[].valueFrom
Optional | string
| | containerDefinitions.[].startTimeout
Optional | integer
| | containerDefinitions.[].stopTimeout
Optional | integer
| | containerDefinitions.[].systemControls
Optional | array
| | containerDefinitions.[].systemControls.[]
Required | object
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container (https://docs.docker.com/engine/api/v1.35/#operation/ContainerCreate) section of the Docker Remote API (https://docs.docker.com/engine/api/v1.35/) and the –sysctl option to docker run (https://docs.docker.com/engine/reference/run/#security-configuration). For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.

We don’t recommend that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode. Doing this has the following disadvantages:

• For tasks that use the awsvpc network mode including Fargate, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that’s started last determines which systemControls take effect.

• For tasks that use the host network mode, the network namespace systemControls aren’t supported.

If you’re setting an IPC resource namespace to use for the containers in the task, the following conditions apply to your system controls. For more information, see IPC mode (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html#task_definition_ipcmode).

• For tasks that use the host IPC mode, IPC namespace systemControls aren’t supported.

• For tasks that use the task IPC mode, IPC namespace systemControls values apply to all containers within a task.

This parameter is not supported for Windows containers.

This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn’t supported for Windows containers on Fargate. || containerDefinitions.[].systemControls.[].namespace
Optional | string
| | containerDefinitions.[].systemControls.[].value
Optional | string
| | containerDefinitions.[].ulimits
Optional | array
| | containerDefinitions.[].ulimits.[]
Required | object
The ulimit settings to pass to the container.

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 default nofile soft limit is 1024 and the default hard limit is 65535.

You can specify the ulimit settings for a container in a task definition. || containerDefinitions.[].ulimits.[].hardLimit
Optional | integer
| | containerDefinitions.[].ulimits.[].name
Optional | string
| | containerDefinitions.[].ulimits.[].softLimit
Optional | integer
| | containerDefinitions.[].user
Optional | string
| | containerDefinitions.[].volumesFrom
Optional | array
| | containerDefinitions.[].volumesFrom.[]
Required | object
Details on a data volume from another container in the same task definition. || containerDefinitions.[].volumesFrom.[].readOnly
Optional | boolean
| | containerDefinitions.[].volumesFrom.[].sourceContainer
Optional | string
| | containerDefinitions.[].workingDirectory
Optional | string
| | cpu
Optional | string
The number of CPU units used by the task. It can be expressed as an integer
using CPU units (for example, 1024) or as a string using vCPUs (for example,
1 vCPU or 1 vcpu) in a task definition. String values are converted to an
integer indicating the CPU units when the task definition is registered.

Task-level CPU and memory parameters are ignored for Windows containers.
We recommend specifying container-level resources for Windows containers.

If you’re using the EC2 launch type, this field is optional. Supported values
are between 128 CPU units (0.125 vCPUs) and 10240 CPU units (10 vCPUs). If
you do not specify a value, the parameter is ignored.

If you’re using the Fargate launch type, this field is required and you must
use one of the following values, which determines your range of supported
values for the memory parameter:

The CPU units cannot be less than 1 vCPU when you use Windows containers
on Fargate.

* 256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB),
2048 (2 GB)

* 512 (.5 vCPU) - Available memory values: 1024 (1 GB), 2048 (2 GB), 3072
(3 GB), 4096 (4 GB)

* 1024 (1 vCPU) - Available memory values: 2048 (2 GB), 3072 (3 GB), 4096
(4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB)

* 2048 (2 vCPU) - Available memory values: 4096 (4 GB) and 16384 (16 GB)
in increments of 1024 (1 GB)

* 4096 (4 vCPU) - Available memory values: 8192 (8 GB) and 30720 (30 GB)
in increments of 1024 (1 GB)

* 8192 (8 vCPU) - Available memory values: 16 GB and 60 GB in 4 GB increments
This option requires Linux platform 1.4.0 or later.

* 16384 (16vCPU) - Available memory values: 32GB and 120 GB in 8 GB increments
This option requires Linux platform 1.4.0 or later. | | ephemeralStorage
Optional | object
The amount of ephemeral storage to allocate for the task. This parameter
is used to expand the total amount of ephemeral storage available, beyond
the default amount, for tasks hosted on Fargate. For more information, see
Using data volumes in tasks (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/using_data_volumes.html)
in the Amazon ECS Developer Guide.

For tasks using the Fargate launch type, the task requires the following
platforms:

* Linux platform version 1.4.0 or later.

* Windows platform version 1.0.0 or later. | | ephemeralStorage.sizeInGiB
Optional | integer
| | executionRoleARN
Optional | string
The Amazon Resource Name (ARN) of the task execution role that grants the
Amazon ECS container agent permission to make Amazon Web Services API calls
on your behalf. The task execution IAM role is required depending on the
requirements of your task. For more information, see Amazon ECS task execution
IAM role (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_execution_IAM_role.html)
in the Amazon Elastic Container Service Developer Guide. | | family
Required | string
You must specify a family for a task definition. You can use it track multiple
versions of the same task definition. The family is used as a name for your
task definition. Up to 255 letters (uppercase and lowercase), numbers, underscores,
and hyphens are allowed. | | inferenceAccelerators
Optional | array
The Elastic Inference accelerators to use for the containers in the task. | | inferenceAccelerators.[]
Required | object
Details on an Elastic Inference accelerator. For more information, see Working with Amazon Elastic Inference on Amazon ECS (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-inference.html) in the Amazon Elastic Container Service Developer Guide. || inferenceAccelerators.[].deviceName
Optional | string
| | inferenceAccelerators.[].deviceType
Optional | string
| | ipcMode
Optional | string
The IPC resource namespace to use for the containers in the task. The valid
values are host, task, or none. If host is specified, then all containers
within the tasks that specified the host IPC mode on the same container instance
share the same IPC resources with the host Amazon EC2 instance. If task is
specified, all containers within the specified task share the same IPC resources.
If none is specified, then IPC resources within the containers of a task
are private and not shared with other containers in a task or on the container
instance. If no value is specified, then the IPC resource namespace sharing
depends on the Docker daemon setting on the container instance. For more
information, see IPC settings (https://docs.docker.com/engine/reference/run/#ipc-settings—ipc)
in the Docker run reference.

If the host IPC mode is used, be aware that there is a heightened risk of
undesired IPC namespace expose. For more information, see Docker security
(https://docs.docker.com/engine/security/security/).

If you are setting namespaced kernel parameters using systemControls for
the containers in the task, the following will apply to your IPC resource
namespace. For more information, see System Controls (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html)
in the Amazon Elastic Container Service Developer Guide.

* For tasks that use the host IPC mode, IPC namespace related systemControls
are not supported.

* For tasks that use the task IPC mode, IPC namespace related systemControls
will apply to all containers within a task.

This parameter is not supported for Windows containers or tasks run on Fargate. | | memory
Optional | string
The amount of memory (in MiB) used by the task. It can be expressed as an
integer using MiB (for example ,1024) or as a string using GB (for example,
1GB or 1 GB) in a task definition. String values are converted to an integer
indicating the MiB when the task definition is registered.

Task-level CPU and memory parameters are ignored for Windows containers.
We recommend specifying container-level resources for Windows containers.

If using the EC2 launch type, this field is optional.

If using the Fargate launch type, this field is required and you must use
one of the following values. This determines your range of supported values
for the cpu parameter.

The CPU units cannot be less than 1 vCPU when you use Windows containers
on Fargate.

* 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available cpu values: 256 (.25
vCPU)

* 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available cpu values:
512 (.5 vCPU)

* 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168
(7 GB), 8192 (8 GB) - Available cpu values: 1024 (1 vCPU)

* Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) -
Available cpu values: 2048 (2 vCPU)

* Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) -
Available cpu values: 4096 (4 vCPU)

* Between 16 GB and 60 GB in 4 GB increments - Available cpu values: 8192
(8 vCPU) This option requires Linux platform 1.4.0 or later.

* Between 32GB and 120 GB in 8 GB increments - Available cpu values: 16384
(16 vCPU) This option requires Linux platform 1.4.0 or later. | | networkMode
Optional | string
The Docker networking mode to use for the containers in the task. The valid
values are none, bridge, awsvpc, and host. If no network mode is specified,
the default is bridge.

For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For
Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used.
For Amazon ECS tasks on Amazon EC2 Windows instances, or awsvpc
can be used. If the network mode is set to none, you cannot specify port
mappings in your container definitions, and the tasks containers do not have
external connectivity. The host and awsvpc network modes offer the highest
networking performance for containers because they use the EC2 network stack
instead of the virtualized network stack provided by the bridge mode.

With the host and awsvpc network modes, exposed container ports are mapped
directly to the corresponding host port (for the host network mode) or the
attached elastic network interface port (for the awsvpc network mode), so
you cannot take advantage of dynamic host port mappings.

When using the host network mode, you should not run containers using the
root user (UID 0). It is considered best practice to use a non-root user.

If the network mode is awsvpc, the task is allocated an elastic network interface,
and you must specify a NetworkConfiguration value when you create a service
or run a task with the task definition. For more information, see Task Networking
(https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-networking.html)
in the Amazon Elastic Container Service Developer Guide.

If the network mode is host, you cannot run multiple instantiations of the
same task on a single container instance when port mappings are used.

For more information, see Network settings (https://docs.docker.com/engine/reference/run/#network-settings)
in the Docker run reference. | | pidMode
Optional | string
The process namespace to use for the containers in the task. The valid values
are host or task. On Fargate for Linux containers, the only valid value is
task. For example, monitoring sidecars might need pidMode to access information
about other containers running in the same task.

If host is specified, all containers within the tasks that specified the
host PID mode on the same container instance share the same process namespace
with the host Amazon EC2 instance.

If task is specified, all containers within the specified task share the
same process namespace.

If no value is specified, the default is a private namespace for each container.
For more information, see PID settings (https://docs.docker.com/engine/reference/run/#pid-settings—pid)
in the Docker run reference.

If the host PID mode is used, there’s a heightened risk of undesired process
namespace exposure. For more information, see Docker security (https://docs.docker.com/engine/security/security/).

This parameter is not supported for Windows containers.

This parameter is only supported for tasks that are hosted on Fargate if
the tasks are using platform version 1.4.0 or later (Linux). This isn’t supported
for Windows containers on Fargate. | | placementConstraints

Optional | object
The configuration details for the App Mesh proxy.

For tasks hosted on Amazon EC2 instances, the container instances require
at least version 1.26.0 of the container agent and at least version 1.26.0-1
of the ecs-init package to use a proxy configuration. If your container instances
are launched from the Amazon ECS-optimized AMI version 20190301 or later,
then they contain the required versions of the container agent and ecs-init.

have only one value.

* Maximum key length - 128 Unicode characters in UTF-8

* Maximum value length - 256 Unicode characters in UTF-8

* If your tagging schema is used across multiple services and resources,
remember that other services may have restrictions on allowed characters.
Generally allowed characters are: letters, numbers, and spaces representable
in UTF-8, and the following characters: + - = . _ : / @.

* Tag keys and values are case-sensitive.

* Do not use aws:, AWS:, or any upper or lowercase combination of such
