Sometimes we make mistakes. When first learning docker we probably make many mistakes and end up with tons of unused docker images.
If you are on Linux like me, you won’t have a desktop dashboard like Mac and Windows get, so things are harder. To see a list of what images you have created you use the following command
docker ps -a
That command will output something like this.
It will show the CONTAINER ID, IMAGE, COMMAND etc. as you can see. To delete an image you use the container id with docker rm like this.
docker rm b5f8fae52bce
I’ve seen older internet posts using the IMAGE value but I had no success with that method. I am guessing something changed. I didn’t even see an example of this I just tried it. I don’t see any mention of this in the docs either. But it works. This part in the getting started intro actually explains it. I think something did change.
