Unable to Copy s3 files inside Docker container

Question

Am new to docker and aws. I am trying to create a Jmeter Image and pass on the JMX script during runtime. For that, i thought copying files from S3 inside a container will be a best fit. So initially i tried to copy the files from s3 to my local host using the below command

aws s3 cp s3://bucketname/sample.jmx .

I was able to download the file successfully into my local system. After then i have created a docker images with latest AWS CLI installed and tried the same, the message shows "download: s3://bucketname/sample.jmx to current folder " but am not able to see the file. But on the other hand, i was able to copy the file from docker to S3 using the command

aws s3 cp /tmp/sample.jmx s3://bucketname/

Further details :

1. Image on - alpine:3.12.4

2. Credentials - Passed inline with the docker run command like below

   docker run -it --rm -e AWS_DEFAULT_REGION='us-east-2' -e AWS_ACCESS_KEY_ID='aaaaaa' -e AWS_SECRET_ACCESS_KEY='dsfssdfds' dockerimage aws s3 cp s3://bucketname/sample.jmx /tmp

I would really need some help here.
