AutoGluon example notebook docker image build `no space left on device` error with non root user

We are trying to build AutoGluon training and inference docker images using ec-user(without root access) and Sagemaker notebook [AutoGluon_Tabular_SageMaker.ipynb](https://github.com/aws/amazon-sagemaker-examples/blob/master/advanced_functionality/autogluon-tabular/AutoGluon_Tabular_SageMaker.ipynb)

Docker image building process fails with "no space left on device" error.

For the same Sagemaker instance, after enabling root access, the example works fine without any space issues.

Can we get some guidelines about using docker over sagemaker notebook with non root user and not running into space issue.

instance_type = 'ml.m5.2xlarge'


Start with advanced_functionality/autogluon-tabular/AutoGluon_Tabular_SageMaker.ipynb and reproduce the Docker image build on an ml.m5.2xlarge SageMaker notebook as ec-user without root access. Determine whether the example or its usage guidance needs changing; done means the non-root build no longer fails with “no space left on device,” or the limitation and required guidance are documented.
