How to pull the AWS ECR docker image and extract all things in the docker image?

#aws #ecs #docker

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
Enter fullscreen mode Exit fullscreen mode

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
Enter fullscreen mode Exit fullscreen mode

For example:



docker run --rm -it --entrypoint=/bin/bash YOUR_DOCKER_IMAGE_URL ls -la
Enter fullscreen mode Exit fullscreen mode

Extract Docker image and searching in the files 



 docker image save YOUR_DOCKER_IMAGE_URL > img.tar
Enter fullscreen mode Exit fullscreen mode

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



 tar -xvf img.tar
Enter fullscreen mode Exit fullscreen mode
