Hello - When using ECS/Fargate is there a way to set the dnsServers on the task definition without providing a custom task definition?

Hi @Robert Bastian! Maybe you can use the

run_task_kwargs

of ECSRun? Doc

It doesn’t look like “dnsServers” is a parameter you can pass to ECS.client.run_task.

That would be the only route to set something without the custom task definition so if it can’t be done there I don’t think there’s another way unfortuntately

OK, so it looks like this isn’t possible: Check:

botocore.errorfactory.ClientException: An error occurred (ClientException) when calling the RegisterTaskDefinition operation: DNS servers are not supported on container when networkMode=awsvpc.

and, mate:

For Amazon ECS tasks on Fargate, the awsvpc network mode is required.
