Trying to BUILD & PUSH ‘tfrecord-processing’ Docker image AWS – User denied

I am following this tutorial right here: and I am trying to build and push tfrecord-processing docker image by executing following command:

!sh ./docker/ $image_name

Everything seems to go fine until very end:

Here is the code for

#!/usr/bin/env bash

# This script shows how to build the Docker image and push it to ECR to be ready for use
# by SageMaker.

# The argument to this script is the image name. This will be used as the image on the local
# machine and combined with the account and region to form the repository name for ECR.

if [[ "$image" == "" ]]
    echo "Usage: $0 <image-name>"
    exit 1

# Get the account number associated with the current IAM credentials
account=$(aws sts get-caller-identity --query Account --output text)
if [[ $? -ne 0 ]]
    exit 25

# Get the region defined in the current configuration (default to us-west-2 if none defined)
region=$(aws configure get region)

# If the repository doesn't exist in ECR, create it.
aws ecr describe-repositories --repository-names "${image}" > /dev/null 2>&1
if [[ $? -ne 0 ]]
    aws ecr create-repository --repository-name "${image}" > /dev/null

# Get the login command from ECR and execute it directly
$(aws ecr get-login --region ${region} --no-include-email)

# Build the docker image locally with the image name and then push it to ECR
# with the full name.
cd docker/

echo "Building image with name ${image}"
docker build --no-cache -t ${image} -f Dockerfile .
docker tag ${image} ${fullname}

echo "Pushing image to ECR ${fullname}"
docker push ${fullname}

# Writing the image name to let the calling process extract it without manual intervention:
echo "${fullname}" > ecr_image_fullname.txt

I guess I need to set some roles for my user, but not sure which or where. Please help.
