2021年1月17日

For task definitions that use the awsvpc network mode, you should only specify the containerPort . An object representing a container instance host device. Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. For Amazon ECS tasks on Amazon EC2 instances, any network mode can be used. The name of the container that will serve as the App Mesh proxy. For more information see KernelCapabilities . If a task-level memory value is specified then the container-level memory value is optional. Custom metadata to add to your Docker volume. If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. 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. By default, containers use the same logging driver that the Docker daemon uses. A list of container definitions in JSON format that describe the different containers that make up your task. Each line in an environment file should contain an environment variable in VARIABLE=VALUE format. If this parameter is omitted, a container is assumed to be essential. A fully qualified domain name hosted by an, A cluster query language expression to apply to the constraint. If specifying a UID or GID, you must specify it as a positive integer. If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. This parameter is only supported if the network mode of a task definition is bridge . For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path . You can specify up to ten environment files. To use bind mounts, specify the host parameter instead. This field is only used if the scope is shared . First time using the AWS CLI? A list of files containing the environment variables to pass to a container. Port mappings allow containers to access ports on the host container instance to send or receive traffic. For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide . Windows containers cannot mount directories on a different drive, and mount point cannot be across drives. When this parameter is true, the container is given elevated privileges on the host container instance (similar to the root user). 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. The options to use when configuring the log router. This parameter maps to VolumesFrom in the Create a container section of the Docker Remote API and the --volumes-from option to docker run . This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run . For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide . This parameter maps to DnsSearch in the Create a container section of the Docker Remote API and the --dns-search option to docker run . When this parameter is true, networking is disabled within the container. The Amazon FSx for Windows File Server file system ID to use. Lines beginning with # are treated as comments and are ignored. This parameter is not supported for Windows containers. This parameter maps to Dns in the Create a container section of the Docker Remote API and the --dns option to docker run . An object representing the secret to expose to your container. An object representing the secret to expose to your container. The value for the specified resource type. If enabled, transit encryption must be enabled in the. For more information, see Using Data Volumes in Tasks . The string array must start with CMD to execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. The Elastic Inference accelerators to use for the containers in the task. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide . The value for the size (in MiB) of the /dev/shm volume. This parameter maps to. When you are using the Amazon ECS API, AWS CLI, or AWS SDK, if the secret exists in the same Region as the task that you are launching then you can use either the full ARN or the name of the secret. The list of volume definitions for the task. Details on a data volume from another container in the same task definition. If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. All containers in this task are granted the permissions that are specified in this role. A list of container definitions in JSON format that describe the different containers that make up your task. This JSON structure above does the following: it defines an ECS task called mywebsite that has a certain amount of CPU and memory capacity associated to it (it reserves 256 CPU units and 512MB of memory on the EC2 instance it is started on). The command that is passed to the container. For tasks that use the Fargate launch type, capabilities is supported for all platform versions but the add parameter is only supported if using platform version 1.4.0 or later. The minimum valid CPU share value that the Linux kernel allows is 2. Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. The amount (in MiB) of memory to present to the container. Note: For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide. The metadata that is applied to the task definition to help you categorize and organize them. The absolute file path where the tmpfs volume is to be mounted. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . Accepted values are 0 or any positive integer. For tasks that use a bind mount host volume, specify a host and optional sourcePath . For more information, see Creating a Task Definition that Uses a FireLens Configuration in the Amazon Elastic Container Service Developer Guide . The container instance attributes required by your task. 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 maps to the --shm-size option to docker run . Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries. See the The namespaced kernel parameter for which to set a, The value for the namespaced kernel parameter specified in, The type of resource to assign to a container. Tasks or applications that need to connect to your Amazon ECS service can locate an existing task from the DNS record. For tasks using the EC2 launch type, 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 enable a proxy configuration. The name of the container that will serve as the App Mesh proxy. This parameter maps to the --tmpfs option to docker run . String values are converted to an integer indicating the MiB when the task definition is registered. The container path, mount options, and size (in MiB) of the tmpfs mount. If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If this value is true , the Docker volume is created if it does not already exist. If using the Fargate launch type, this parameter is optional. You can specify the user using the following formats. This parameter is specified when you are using Docker volumes. Images in other online repositories are qualified further by a domain name (for example, To inject sensitive data into your containers as environment variables, use the, To reference sensitive information in the log configuration of a container, use the, 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB) - Available, 1024 (1 GB), 2048 (2 GB), 3072 (3 GB), 4096 (4 GB) - Available, 2048 (2 GB), 3072 (3 GB), 4096 (4 GB), 5120 (5 GB), 6144 (6 GB), 7168 (7 GB), 8192 (8 GB) - Available, Between 4096 (4 GB) and 16384 (16 GB) in increments of 1024 (1 GB) - Available, Between 8192 (8 GB) and 30720 (30 GB) in increments of 1024 (1 GB) - Available. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. If you are using the Fargate launch type, task placement constraints are not supported. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. The startPeriod is disabled by default. You can create an ECR repository with a command like the one below, where the name of your repo is my-ecr-repo and the region is us-west-2: aws ecr create-repository --repository-name my-ecr-repo --region us-west-2. If this field is omitted, tags are not included in the response. For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later. If you are using containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version. When running tasks using the host network mode, you should not run containers using the root user (UID 0). Each tag consists of a key and an optional value, both of which you define. help getting started. Before you can run Docker containers on Amazon ECS, you must create a task definition.
