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
