public CfnTaskDefinition.ContainerDefinitionProperty.Builder command(java.util.List<java.lang.String> command)
CfnTaskDefinition.ContainerDefinitionProperty.getCommand()command - 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 the COMMAND parameter to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#cmd . If there are multiple arguments, each argument is a separated string in the array.thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder cpu(java.lang.Number cpu)
CfnTaskDefinition.ContainerDefinitionProperty.getCpu()cpu - The number of `cpu` units reserved for the container.
This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run .
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder dependsOn(IResolvable dependsOn)
CfnTaskDefinition.ContainerDefinitionProperty.getDependsOn()dependsOn - The dependencies defined for container startup and shutdown.
A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on 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 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 in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires the following platforms:

thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder logConfiguration(IResolvable logConfiguration)
CfnTaskDefinition.ContainerDefinitionProperty.getLogConfiguration()logConfiguration - 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 may 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 on 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_DRIVERSenvironment 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 .
thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder logConfiguration(CfnTaskDefinition.LogConfigurationProperty logConfiguration)

thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder memory(java.lang.Number memory)
CfnTaskDefinition.ContainerDefinitionProperty.getMemory()memory - The amount (in MiB) of memory to present to the container.
If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run .
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container, so you should not specify fewer than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder memoryReservation(java.lang.Number memoryReservation)
CfnTaskDefinition.ContainerDefinitionProperty.getMemoryReservation()memoryReservation - The soft limit (in MiB) of memory to reserve for the container.
When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run .
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker daemon reserves a minimum of 4 MiB of memory for a container. Therefore, we recommend that you specify fewer than 4 MiB of memory for your containers.

thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder name(java.lang.String name)
CfnTaskDefinition.ContainerDefinitionProperty.getName()name - The name of a container.
If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run .thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder portMappings(IResolvable portMappings)
CfnTaskDefinition.ContainerDefinitionProperty.getPortMappings()portMappings - The list of port mappings for the container.
Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, you should only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run . If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
After a task reaches the
RUNNINGstatus, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in thenetworkBindingssection DescribeTasks responses.

CfnTaskDefinition.ContainerDefinitionProperty.getStartTimeout()startTimeout - Time duration (in seconds) to wait before giving up on resolving dependencies for a container.
For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.
When the
ECS_CONTAINER_START_TIMEOUTcontainer agent configuration variable is used, it's enforced independently from this start timeout value.
For tasks using the Fargate launch type, the task or service requires the following platforms:
1.3.0 or later.1.0.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. 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 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 in the Amazon Elastic Container Service Developer Guide .
thispublic CfnTaskDefinition.ContainerDefinitionProperty.Builder stopTimeout(java.lang.Number stopTimeout)
CfnTaskDefinition.ContainerDefinitionProperty.getStopTimeout()stopTimeout - Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
1.3.0 or later.1.0.0 or later.The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. 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 in the Amazon Elastic Container Service Developer Guide .

CfnTaskDefinition.ContainerDefinitionProperty.getSystemControls()systemControls - A list of namespaced kernel parameters to set in the container.
This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
We don't recommended that you specify network-related
systemControlsparameters for multiple containers in a single task that also uses either theawsvpcorhostnetwork modes. For tasks that use theawsvpcnetwork mode, the container that's started last determines whichsystemControlsparameters take effect. For tasks that use thehostnetwork mode, it changes the container instance's namespaced kernel parameters as well as the containers.
