Error while running container

Sorry, I amm not sure I understand what you want to say here.

If the script you shared now is the install.sh, why it contains the following?

It tries to execute install.sh. It could be an other file with the same name if the script changed the directory before that line.

22

This is another option to execute script (install.sh) in silent mode, here for time being it can be ignored.

Hi, Is it mandatory to use base image for building image through Dockerfile? if yes, how to proceed for any app containerization whose base image is not found under docker hub?

24

You can use any base image from any registry and push to any registry if you want. You could create an image from scratch (FROM scratch) which means you need to create the entire filesystem and copy into the image.

You could also install interactively and commit the container to an image but that is a bad practice:

docker container commit $container_name $image_name

Use that only if you are yure sou don’t have any other option. I have never done that except to demonstrate how that command works.
