Intro

Maybe you faced the problem that you have been needed the old docker file in the ECR repository.
I solved this problem with the docker command to pull and extract the docker image and access all I need.

Pulling Docker image file

You can use the below command to pull the docker image that you push in the ECR repository:

docker pull YOUR_DOCKER_IMAGE_URL

Run your desire command in docker image

You can run and execute a command in your docker image:

docker run --rm -it --entrypoint=/bin/bash YOUR_DOCKER_IMAGE_URL

For example:

docker run --rm -it --entrypoint=/bin/bash YOUR_DOCKER_IMAGE_URL ls -la

Extract Docker image and searching in the files

 docker image save YOUR_DOCKER_IMAGE_URL > img.tar

After that, you extract the docker image and find your target files:

 tar -xvf img.tar
