Delete docker image with all tags
Scenario
I have docker image with several tags. I want to remove this docker image with all its tags. If I do that manually I want to list the tags and delete one by one.
Command
I have found some way to delete the images and all its tags with single command. It combine various commands with linux pipe |
Following are the break down of all commands that I have used
1. docker images
List all docker images. I have quite a lot of docker images. :)
2. grep
grep the images that contain the name chainz
3. tr -s
tr utility copies the given input to produced the output with substitution or deletion of selected characters. In here I’m removing spaces of previous command output.
4. cut -d
cut command allows to extract the specific part from a text. In here I’m extracting the tag part.
5. xargs -I
xargs command allows to convert input of standard input into argument of another command. In above command it returns a list of tags, I can echo the full name of the image with the tag by using xargs
To delete the image with all its tags, I can xargs the docker tag inputs to docker rmi command.
