How to run the docker image with tag

Question

I have a docker image with <none> tag.

I want to run the hello-world image with TAG <none>. How can I do that?

Answer 1

In order to run a dangling image, you first need to tag that image. You can do this by using image ID.

For example:

docker tag [IMAGE_ID] [REPOSITORY]:[TAG]

Now you can run that image with the tag you just defined.

Answer 2

You can run a container from a specific image by using the image's ID, like:

docker run -it efb6339f1b3e /bin/bash

If you want to give your image a tag, you can do that by using -t option in the docker build command, like:

docker build -t codinghaus/hello-world:1.0.0

Answer 3

docker tag <image-name> <image-name>[:tag]

Example:

docker tag hello_world hello_world[:2]

Answer 4

I ran it like this successfully and the tag of the image is 'none'

Command on Macos: docker run -it --entrypoint=/bin/bash --env-file ~/docker/env.list -u root a480ebfb5d6d9ef62eef279512f6cadb57717efaa8b05afe301c52ed27ff9ef0
