Task definition - Unknown parameter in input: "runtimePlatform"

Question

Hi!  
When I try to register a new task definition with a gravition architecture I receive an errror:  
  
# aws ecs register-task-definition --cli-input-json file://td_gravinton.json  
  
Parameter validation failed:  
Unknown parameter in input: "runtimePlatform", must be one of: family, taskRoleArn, executionRoleArn, networkMode, containerDefinitions, volumes, placementConstraints, requiresCompatibilities, cpu, memory, tags, pidMode, ipcMode, proxyConfiguration, inferenceAccelerators, ephemeralStorage  
  
I follow the documentation but I don't what's the problem.  
  
Thank you!

Answer

I had the same issue and was able to solve by updating to the latest version of the awscli here https://aws.amazon.com/cli/. Note that I had to uninstall my version installed by brew which was lagging the latest release.

Answer

Could you share the input file (td_graviton.json) and the version of the AWS CLI you're using?  
  
Thanks!

Thank you Mats.  
I tried with this json:  
  
{  
    "runtimePlatform": {  
      "cpuArchitecture": "ARM64",  
      "operatingSystemFamily": "LINUX"  
    },  
    "containerDefinitions": \[  
        {  
            "name": "containerName",  
            "image": "xxxxxxxxxxxxxxxxxxxxx",  
            "cpu": 2048,  
            "memory": 4096,  
            "portMappings": \[  
                {  
                    "containerPort": 80,  
                    "hostPort": 80,  
                    "protocol": "tcp"  
                },  
                {  
                    "containerPort": 22,  
                    "hostPort": 22,  
                    "protocol": "tcp"  
                }  
            ],  
            "essential": true,  
            "environment": \[  
                {  
                    "name": "ENV",  
                    "value": "PRE"  
                }  
            ],  
            "mountPoints": \[],  
            "volumesFrom": \[]  
        }  
    ],  
    "family": "familyName",  
    "taskRoleArn": "xxxxxxxxxxxx",  
    "executionRoleArn": "xxxxxxxxxxxxxxxx",  
    "networkMode": "awsvpc",  
    "volumes": \[],  
    "placementConstraints": \[],  
    "requiresCompatibilities": \[  
        "FARGATE"  
    ],  
    "cpu": "2048",  
    "memory": "4096"  
}  
  
And I tried with this too (example in documentation):  
  
{  
 "family": "bb-arm64",  
 "networkMode": "awsvpc",  
 "containerDefinitions": \[  
    {  
        "name": "sleep",  
        "image": "arm64v8/busybox",  
        "cpu": 100,  
        "memory": 100,  
        "essential": true,  
        "command": \[ "echo hello" ],  
        "entryPoint": \[ "sh", "-c" ]  
    }  
 ],  
 "requiresCompatibilities": \[ "FARGATE" ],  
 "cpu": "1 vCpu",  
 "memory": "3 GB",  
 "runtimePlatform": { "cpuArchitecture": "ARM64" },  
 "executionRoleArn": "arn:aws:iam::1234567890:role/ecsTaskExecutionRole"  
}  
  
In both cases I get the same error, it does not recognize the parameter "runtimePlatform"  
  
My aws client version is:  
#aws --version  
aws-cli/2.2.46 Python/3.9.7 Darwin/19.6.0 source/x86_64 prompt/off  
  
Thank you!!

Answer

Apologies for the delay in responding. I'm unable to repro the issue.  
  
For reference, I'm using AWS CLI v2:  
  
$ aws --version  
aws-cli/2.4.3 Python/3.8.8 Linux/5.4.72-microsoft-standard-WSL2 exe/x86_64.ubuntu.20 prompt/off  
  
With this, and slightly modifying the task definition you provided (specifying busybox as the container and providing a task execution role in my account), I'm able to successfully create the task definition:  
  
{  
    "runtimePlatform": {  
        "cpuArchitecture": "ARM64",  
        "operatingSystemFamily": "LINUX"  
    },  
    "containerDefinitions": \[  
        {  
            "name": "containerName",  
            "image": "arm64v8/busybox",  
            "cpu": 2048,  
            "memory": 4096,  
            "portMappings": \[  
                {  
                    "containerPort": 80,  
                    "hostPort": 80,  
                    "protocol": "tcp"  
                },  
                {  
                    "containerPort": 22,  
                    "hostPort": 22,  
                    "protocol": "tcp"  
                }  
            ],  
            "essential": true,  
            "environment": \[  
                {  
                    "name": "ENV",  
                    "value": "PRE"  
                }  
            ],  
            "mountPoints": \[],  
            "volumesFrom": \[]  
        }  
    ],  
    "family": "forum-post-td-1",  
    "executionRoleArn": "arn:aws:iam::ACCOUNT-ID-GOES-HERE:role/ecsTaskExecutionRole",  
    "networkMode": "awsvpc",  
    "volumes": \[],  
    "placementConstraints": \[],  
    "requiresCompatibilities": \[  
        "FARGATE"  
    ],  
    "cpu": "2048",  
    "memory": "4096"  
}
