I created a new image using:
docker build myimagename .
Then I ran it using:
docker run -it myimagename
I exit. Then I try to delete the image using:
docker rmi myimagename
At this point is I get the error:
Error response from daemon: conflict: unable to remove repository reference "myimagename" (must force) – container 474fb07acd2a is using its referenced image f5fdf1fb2339
However, when I check using
docker container ls -a the container list shows that container exited. So why is the image removal blocked?
