How to find out the base image for a docker image

Question

I have a docker image and I would like to find out from which image it has been created. Of course there are multiple layers, but I'd like to find out the last image (the FROM statement in the dockerfile for this image)?

I try to use docker image history and docker image inspect but I can't find this information in there.

I tried to use the following command but it gives me a error message

alias dfimage="sudo docker run -v /var/run/docker.sock:/var/run/docker.sock --rm xyz/mm:9e945ff" dfimage febae8978318 

This is the error message I'm getting

container_linux.go:235: starting container process caused "exec: \"febae8978318\": executable file not found in $PATH" /usr/bin/docker-current: Error response from daemon: oci runtime error: container_linux.go:235: starting container process caused "exec: \"febae8978318\": executable file not found in $PATH". 

Answer 1

Easy way is to use

docker image history deno 

This above command will give you output like this

Then just look at the IMAGE column and take that image ID which a24bb4013296 which is just above the first <missing>

Then just do the

For Linux

docker image ls | grep a24bb4013296 

For Windows

docker image ls | findstr a24bb4013296 

This will give you the base image name
