I am running a service in AWS ECS. From inside the container, I am trying to build and push a new image (using Kaniko) to ECR but I am facing the following error every time:

error checking push permissions -- make sure you entered the correct tag name, and that you are authenticated correctly, and try again: checking push permission for "${account_id}.dkr.ecr.${region}.amazonaws.com/${repo_name}:${tag_name}”: POST https://${account_id}.dkr.ecr.${region}.amazonaws.com/${location}: unexpected status code 401 Unauthorized: Not Authorized

Here is the Shell Script I am using for building the image:

aws ecr get-login-password --region ${region}

/kaniko/executor --dockerfile ${docker_file_path} 
    --destination ${repo_tag_name} 
    --build-arg account_id=${account} 
    --build-arg env=${exec_stage} 
    --build-arg python_version=${python_version} 
    --build-arg model_class=${model_class} 
    --build-arg model_pickle=${model_pickle} 
    --build-arg model_attributes=${model_attributes} 
    --build-arg requirements=${requirements} 
    --build-arg predictor=${predictor} 
    --build-arg http_proxy=${http_proxy} 
    --build-arg https_proxy=${https_proxy} 
    --build-arg region=${region}

My service is up and running and it executes all the tasks perfectly such as consuming messages from the message broker, downloading artefacts from s3 bucket. But whenever I am trying to push the image built by Kaniko to ECR, it fails.

I’m expecting that the image should be pushed to ECR without having any docker dependency
