Let us take a close look at how to set up the AWS ECS taskdefinition. At Bobcares, our AWS support services can give you a complete guide on the whole process.

AWS::ECS::TaskDefinition

The AWS::ECS::TaskDefinition is an Amazon ECS task and volume detalis. We can define the Docker images to utilize, and the necessary resources.  We can also define other settings for starting the taskdefinition via an Amazon ECS service or task.

Syntax

Use the following syntax to declare this object in the AWS CloudFormation:

JSON

{ "Type" : "AWS::ECS::TaskDefinition",
"Properties" : {
"ContainerDefinitions" : [ ContainerDefinition, ... ], "Cpu" : String,
"EphemeralStorage" : EphemeralStorage,
"ExecutionRoleArn" : String,
"Family" : String,
"InferenceAccelerators" : [ InferenceAccelerator, ... ], "IpcMode" : String,
"Memory" : String,
"NetworkMode" : String,
"PidMode" : String,
"PlacementConstraints" : [ TaskDefinitionPlacementConstraint, ... ], "ProxyConfiguration" : ProxyConfiguration, "RequiresCompatibilities" : [ String, ... ], "RuntimePlatform" : RuntimePlatform,
"Tags" : [ Tag, ... ],
"TaskRoleArn" : String,
"Volumes" : [ Volume, ... ]
}
}

AWS ECS Taskdefinition

PDFRSS

To execute Docker on Amazon ECS, a task definition is necessary. Some of the rules to specify in a task are as follows:

• Firstly, the Docker image to use for each job.
• The amount of CPU and memory for each job within a task.
• After that, the kind of launch to employ to state the job hosting frame.
• The Docker networking mode to use for the task’s containers.
• After that, the logging settings.
• If the ECS ends or fails if the job continues to execute.
• The command that the container executes when it boots up.
• After that, any data volumes related to the task’s containers.
• Finally, the IAM role that the tasks make use of.

An AWS ECS taskdefinition can have many containers. The task’s launch type determines the rules that we can employ. All rules are not valid.

The whole application stack does not need to be on a single task description, and in most situations, it is not. The program is capable of covering several task descriptions. We can do this by putting similar containers into their own task descriptions.  Here each of these represents a trait.

Using Task description as a task or as a service

After creating an AWS ECS taskdefinition, we may run it as a task or as a service.

• Within a cluster, a task is the instance of a task description. We can define the number of tasks to run on the cluster. We can do this after giving a task description for the application within Amazon ECS.
• An Amazon ECS service performs and maintains multiple jobs in an Amazon ECS cluster at the same time. The Amazon ECS service will run another instance based on the task if any of the tasks fail or halt. It performs this to replace it and so keep the service running with the required amount of jobs.
