ContainerDefinitionProperty()
public ContainerDefinitionProperty()
Properties
Command
The command that's passed to the container.
public string[] Command { get; set; }
Property Value
System.String[]
Remarks
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.
Cpu
The number of cpu
units reserved for the container.
public Nullable<double> Cpu { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
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.
DependsOn
The dependencies defined for container startup and shutdown.
public object DependsOn { get; set; }
Property Value
System.Object
Remarks
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:
If the task definition is used in a blue/green deployment that uses AWS::CodeDeploy::DeploymentGroup BlueGreenDeploymentConfiguration , the dependsOn
parameter is not supported. For more information see Issue #680 on the on the GitHub website.
DisableNetworking
When this parameter is true, networking is off within the container.
public object DisableNetworking { get; set; }
Property Value
System.Object
Remarks
This parameter maps to NetworkDisabled
in the Create a container section of the Docker Remote API .
This parameter is not supported for Windows containers.
DnsSearchDomains
A list of DNS search domains that are presented to the container.
public string[] DnsSearchDomains { get; set; }
Property Value
System.String[]
Remarks
This parameter maps to DnsSearch
in the Create a container section of the Docker Remote API and the --dns-search
option to docker run .
This parameter is not supported for Windows containers.
DnsServers
A list of DNS servers that are presented to the container.
public string[] DnsServers { get; set; }
Property Value
System.String[]
Remarks
This parameter maps to Dns
in the Create a container section of the Docker Remote API and the --dns
option to docker run .
This parameter is not supported for Windows containers.
DockerLabels
A key/value map of labels to add to the container.
public object DockerLabels { get; set; }
Property Value
System.Object
Remarks
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}}'
DockerSecurityOptions
A list of strings to provide custom configuration for multiple security systems.
public string[] DockerSecurityOptions { get; set; }
Property Value
System.String[]
Remarks
For more information about valid values, see Docker Run Security Configuration . This field isn't valid for containers in tasks using the Fargate launch type.
For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems.
For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide .
This parameter maps to SecurityOpt
in the Create a container section of the Docker Remote API and the --security-opt
option to docker run .
The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true
or ECS_APPARMOR_CAPABLE=true
environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
For more information about valid values, see Docker Run Security Configuration .
Valid values: "no-new-privileges" | "apparmor:PROFILE" | "label:value" | "credentialspec:CredentialSpecFilePath"
EntryPoint
Early versions of the Amazon ECS container agent don't properly handle
entryPoint
parameters.
public string[] EntryPoint { get; set; }
Property Value
System.String[]
Remarks
If you have problems using entryPoint
, update your container agent or enter your commands and arguments as command
array items instead.
The entry point that's passed to the container. This parameter maps to Entrypoint
in the Create a container section of the Docker Remote API and the --entrypoint
option to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint .
Environment
The environment variables to pass to a container.
public object Environment { get; set; }
Property Value
System.Object
Remarks
This parameter maps to Env
in the Create a container section of the Docker Remote API and the --env
option to docker run .
We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.
EnvironmentFiles
A list of files containing the environment variables to pass to a container.
public object EnvironmentFiles { get; set; }
Property Value
System.Object
Remarks
This parameter maps to the --env-file
option to docker run .
You can specify up to ten environment files. The file must have a .env
file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE
format. Lines beginning with #
are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file .
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 in the Amazon Elastic Container Service Developer Guide .
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.
public object Essential { get; set; }
Property Value
System.Object
Remarks
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 tasks 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 .
ExtraHosts
A list of hostnames and IP address mappings to append to the /etc/hosts
file on the container.
public object ExtraHosts { get; set; }
Property Value
System.Object
Remarks
This parameter maps to ExtraHosts
in the Create a container section of the Docker Remote API and the --add-host
option to docker run .
This parameter isn't supported for Windows containers or tasks that use the awsvpc
network mode.
FirelensConfiguration
The FireLens configuration for the container.
public object FirelensConfiguration { get; set; }
Property Value
System.Object
Remarks
This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
HealthCheck
The container health check command and associated configuration parameters for the container.
public object HealthCheck { get; set; }
Property Value
System.Object
Remarks
This parameter maps to HealthCheck
in the Create a container section of the Docker Remote API and the HEALTHCHECK
parameter of docker run .
Hostname
The hostname to use for your container.
public string Hostname { get; set; }
Property Value
System.String
Remarks
This parameter maps to Hostname
in the Create a container section of the Docker Remote API and the --hostname
option to docker run .
The hostname
parameter is not supported if you're using the awsvpc
network mode.
Image
The image used to start a container.
public string Image { get; set; }
Property Value
System.String
Remarks
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
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 .
Interactive
When this parameter is true
, you can deploy containerized applications that require stdin
or a tty
to be allocated.
public object Interactive { get; set; }
Property Value
System.Object
Remarks
This parameter maps to OpenStdin
in the Create a container section of the Docker Remote API and the --interactive
option to docker run .
Links
The links
parameter allows containers to communicate with each other without the need for port mappings.
public string[] Links { get; set; }
Property Value
System.String[]
Remarks
This parameter is only supported if the network mode of a task definition is bridge
. The name:internalName
construct is analogous to name:alias
in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. 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.
LinuxParameters
Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities .
public object LinuxParameters { get; set; }
Property Value
System.Object
Remarks
This parameter is not supported for Windows containers.
LogConfiguration
The log configuration specification for the container.
public object LogConfiguration { get; set; }
Property Value
System.Object
Remarks
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 .
Memory
The amount (in MiB) of memory to present to the container.
public Nullable<double> Memory { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
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.
MemoryReservation
The soft limit (in MiB) of memory to reserve for the container.
public Nullable<double> MemoryReservation { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
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 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less 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, don't specify less than 4 MiB of memory for your containers.
MountPoints
The mount points for data volumes in your container.
public object MountPoints { get; set; }
Property Value
System.Object
Remarks
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.
Name
The name of a container.
public string Name { get; set; }
Property Value
System.String
Remarks
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 .
PortMappings
The list of port mappings for the container.
public object PortMappings { get; set; }
Property Value
System.Object
Remarks
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.
Privileged
When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root
user).
public object Privileged { get; set; }
Property Value
System.Object
Remarks
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 AWS Fargate .
PseudoTerminal
When this parameter is true
, a TTY is allocated.
public object PseudoTerminal { get; set; }
Property Value
System.Object
Remarks
This parameter maps to Tty
in the Create a container section of the Docker Remote API and the --tty
option to docker run .
ReadonlyRootFilesystem
When this parameter is true, the container is given read-only access to its root file system.
public object ReadonlyRootFilesystem { get; set; }
Property Value
System.Object
Remarks
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.
RepositoryCredentials
The private repository authentication credentials to use.
public object RepositoryCredentials { get; set; }
Property Value
System.Object
Remarks
ResourceRequirements
The type and amount of a resource to assign to a container.
public object ResourceRequirements { get; set; }
Property Value
System.Object
Remarks
Secrets
The secrets to pass to the container.
public object Secrets { get; set; }
Property Value
System.Object
Remarks
For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
StartTimeout
Time duration (in seconds) to wait before giving up on resolving dependencies for a container.
public Nullable<double> StartTimeout { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
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_TIMEOUT
container 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:
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 .
StopTimeout
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
public Nullable<double> StopTimeout { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
For tasks using the Fargate launch type, the task or service requires the following platforms:
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 . 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 .
SystemControls
A list of namespaced kernel parameters to set in the container.
public object SystemControls { get; set; }
Property Value
System.Object
Remarks
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 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's 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.
Ulimits
A list of ulimits
to set in the container.
