docker push error : tag does not exist

Question

When pushing a docker image to registry, I got this message :

   docker push   -t   domain.com/repo/tag_docker_name:latest      Error tag name does not exist 

The only way is to create the tag in docker repository via web interface, and then docker push works.

Is there a command line to create docker push ?

Answer 1

You need to add a tag to the image, here is the documentation. Use it like this docker tag 0e5574283393 domain.com/repo/tag_docker_name:latest where 0e5574283393 is the image hash

Answer 2

First there is no option -t for docker push command

Second assume that you already have a tagged image said repo/your_image:tag, you should follow the push syntax docker push repo/your_image:tag, docker host should not be included (in your case domain.com) unless you want to push the image to a private repository.

A simple way to check whether the image name existed is to use docker images, which lists all images available on the host, and image name should be the same as displayed in REPOSITORY column.
