public String name()
The name of a container. If you are 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, hyphens, and underscores 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.
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, hyphens, and underscores
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.public String image()
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker
Hub registry are available by default. Other repositories are specified with either
repository-url/image:tag
or
repository-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 to Image
in the Create a container section of the
Docker Remote API and the IMAGE
parameter of
docker run.
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image are not propagated to already running tasks.
Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag
or registry/repository@digest
. For example,
012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest
or
012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE
.
Images in official repositories on Docker Hub use a single name (for example, ubuntu
or
mongo
).
Images in other repositories on Docker Hub are qualified with an organization name (for example,
amazon/amazon-ecs-agent
).
Images in other online repositories are qualified further by a domain name (for example,
quay.io/assemblyline/ubuntu
).

public RepositoryCredentials repositoryCredentials()
The private repository authentication credentials to use.
public Integer 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.
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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.
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 is 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 would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but 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 is not 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:
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
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 is described in the task definition.

public Integer memory()
The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory
specified here, the container is killed. This parameter maps to Memory
in the Create a container section of the
Docker Remote API and the --memory
option to
docker run.
If your containers are part of a task using the Fargate launch type, this field is optional and the only
requirement is that the total amount of memory reserved for all containers within a task be lower than the task
memory
value.
For containers that are part of a task using the EC2 launch type, you must specify a non-zero integer for one or
both of memory
or memoryReservation
in container definitions. 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 on which the container is placed. Otherwise, the value of memory
is used.
The Docker 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.

The Docker 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.
public Integer 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.
You must specify a non-zero integer for one or both of memory
or memoryReservation
in
container definitions. 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 on which 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, so you should not specify fewer than 4 MiB of memory for your containers.

public List<String> links()
The link
parameter allows containers to communicate with each other without the need for port
mappings. Only supported if the network mode of a task definition is set to bridge
. The
name:internalName
construct is analogous to name:alias
in Docker links. Up to 255
letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. For more information about
linking Docker containers, go to https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/. This parameter maps to
Links
in the Create a
container section of the Docker Remote API and the
--link
option to
docker run
.
This parameter is not supported for Windows containers.
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

public List<PortMapping> 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 RUNNING
status, 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 the networkBindings
section DescribeTasks
responses.

public Boolean essential()
If the essential
parameter of a container is marked as true
, 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
, then its failure does not affect
the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that is composed of multiple containers, you should 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.

A key/value map of labels to add to the container. This parameter maps to Labels
in the Create a container section of the
Docker Remote API and the --label
option to
docker run. 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}}'
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

the following command: sudo docker version --format '{{.Server.APIVersion}}'
public List<Ulimit> ulimits()
A list of ulimits
to set in the container. This parameter maps to Ulimits
in the Create a container section of the
Docker Remote API and the --ulimit
option to
docker run. Valid naming values are displayed in the
Ulimit data type. 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}}'

public LogConfiguration logConfiguration()
The log configuration specification for the container.
If you are using the Fargate launch type, the only supported value is awslogs
.
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_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.

public HealthCheck healthCheck()
The health check command and associated configuration parameters for the container. This parameter maps to
HealthCheck
in the Create a container section of the
Docker Remote API and the HEALTHCHECK
parameter of docker run.
HealthCheck
in the Create a container section
of the Docker Remote API and the
HEALTHCHECK
parameter of docker
run.public List<SystemControl> 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.
It is not recommended that you specify network-related systemControls
parameters for multiple
containers in a single task that also uses either the awsvpc
or host
network modes. For
tasks that use the awsvpc
network mode, the container that is started last determines which
systemControls
parameters take effect. For tasks that use the host
network mode, it
changes the container instance's namespaced kernel parameters as well as the containers.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
