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".

A base image is the image that is used to create all of your container images. Your base image can be an official Docker image, such as Centos, or you can modify an official Docker image to suit your needs, or you can create your own base image from scratch. Parent topic: Docker.
If you use the default storage driver overlay2, then your Docker images are stored in /var/lib/docker/overlay2 . There, you can find different files that represent read-only layers of a Docker image and a layer on top of it that contains your changes.
A Docker image has many layers, and each image includes everything needed to configure a container environment -- system libraries, tools, dependencies and other files. Some of the parts of an image include: Base image. The user can build this first layer entirely from scratch with the build command.
You can use Docker's reserved, minimal image, scratch , as a starting point for building containers. Using the scratch “image” signals to the build process that you want the next command in the Dockerfile to be the first filesystem layer in your image.
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
