docker - pull image and get it's id (linux cli)

I am running this command in centos7 termnial:

 docker pull www.someRepository.com/authorization:latest

Now, I want to run the "docker run" command, but I need to know the id of the image that was created

$id=commandThatParsesTheId

Is there a command that gets the id back from the "docker images" list?

You might be able to clean this up a bit, but the following should work:

    docker pull <someimage> | grep "Digest:" | cut -f2 -d " " > container_digest
    docker images --digests | grep $(cat container_digest) | sed -Ee 's/\s+/ /g' | cut -f4 -d " "

It maps the digest you receive when you pull an image to the image ID.

you can run the "docker run" command on images name also instead of image id

docker pull www.someRepository.com/authorization:latest
docker run -i -t www.someRepository.com/authorization:latest "/bin/bash"

Above one is to run the container for interactive mode.

you can get image id also to run the docker run command

docker images 
docker run -i -t dockerid "/bin/bash"

You can use the name of image and its' tag Or you can use

docker images -q | grep yourimagename

docker images | grep yourimagename | awk {'print $3'}
