Run ecs task definition has error RESOURCE:GPU AGENT

Question

I run ecs task with gpu container instance

In task definition i add gpu to resourceRequirements with ec2 gpu 
for example when i run task with p2.xlarge value of gpu will be 1

I guess my instance does not have enough remaining gpu. 
Is any way for calculate remaining gpu for create task definition?

Thanks!!

You can use the AWS CLI to describe your ECS container instances and extract the relevant information. For example you can do this:

1. Use the AWS CLI to list the ARNs of the container instances in your cluster.
   ```sh
   aws ecs list-container-instances --cluster 
   ```

2. Use the ARNs from the previous step to get detailed information about each instance.
   ```sh
   aws ecs describe-container-instances --cluster  --container-instances   ...
   ```

3. From the output, extract the total and remaining GPUs for each instance. Look for the `registeredResources` and `remainingResources` sections, specifically for entries where the `name` is `GPU`.

4. Subtract the number of GPUs in use from the total number of GPUs to determine the remaining GPUs available for allocation.
