Yes, it is possible to repair a file within a Docker container that has failed to start by accessing the file system of the container and making the necessary changes.
Here are the steps to repair a file within a Docker container:
docker run -it --name=repair-container <image> /bin/bash
docker run -it --name=repair-container --volumes-from <failed-container> <image> /bin/bash
Once inside the container, navigate to the directory where the failed file is located and make the necessary changes.
Exit the container and commit the changes to a new image.
docker commit repair-container <new-image>
docker run -d --name=new-container <new-image>
The new container should now be running with the repaired file.
