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. By default, the container has permissions for read , write , and mknod for the device. The optional grace period within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. When the host parameter is used, specify a sourcePath to declare the path on the host container instance that is presented to the container. Accepted values are 0 or any positive integer.

The minimum valid CPU share value that the Linux kernel allows is 2. If a maxSwap value of 0 is specified, the container will not use swap. 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. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. For task definitions that use the awsvpc network mode, you should only specify the containerPort . Also, several suggestions that I found in StackOverflow and forums, but in the best cases, I ended with 4 tasks, while, I just want to replace the current ones with new ones.

Returns a list of task definitions that are registered to your account. The soft limit (in MiB) of memory to reserve for the container. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself. A string array representing the command that the container runs to determine if it is healthy. To view this page for the AWS CLI version 2, click If a value is not specified for maxSwap then this parameter is ignored. The port number on the container that is bound to the user-specified or automatically assigned host port. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. Windows containers only have access to the specified amount of CPU that is described in the task 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). If you are using the EC2 launch type, this field is optional. Please follow the instructions to set up the AWS CLI and configure it with your identity. If you are using tasks that use the Fargate launch type, the swappiness parameter is not supported. If there are multiple arguments, each argument should be a separated string in the array. Early versions of the Amazon ECS container agent do not properly handle entryPoint parameters. The revision is a version number of a task definition in a family. The following register-task-definition example registers a task definition to the specified family with container definitions that are saved in JSON format at the specified file location. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide . The supported resource types are GPUs and Elastic Inference accelerators. 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}}'.

You can define multiple containers in a task definition. For more information, see Docker security . Docker for Windows uses different network modes than Docker for Linux. All containers in this task are granted the permissions that are specified in this role. For tasks using the EC2 launch type, if the stopTimeout parameter is not specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used by default. If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 is used. If the AWS Systems Manager Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. The only supported value is. When a dependency is defined for container startup, for container shutdown it is reversed. If the host PID mode is used, be aware that there is a heightened risk of undesired process namespace expose. If you are using tasks that use the Fargate launch type, the maxSwap parameter is not supported. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . You can specify a Docker networking mode for the containers in your task definition with the networkMode parameter.
