Containerd: Failed to ctr push with non latest tag

[bluefriday]

What is the problem you're trying to solve
I've tried to push/pull test for using ctr in my custom registry service.
Even though success to push/pull with latest tag, I failed to push with 'non-latest' tag
(I think ctr doesn't support docker's tag command)

Describe the solution you'd like
Can I change the tag name using 'ctr command' or push it to a 'non-latest' tag?

Additional context
Below are my logs

thanks for reporting. could you mind to show the result ctr image ls | grep 5001 ? I am not sure that you pulled the image into your local ..... docker doesn't have used containerd to manage image store yet.

Thanks a lot! I didn't know if containerd and docker use different local storage.
My containerd local storage didn't have that image, so it wasn't being pushed.
But I couldn't change the tag with ctr command, so I used the docker client.
Is there any way to change the ctr image tag?

Hi @bluefriday . I think you are using v1.2.x containerd version. You use containerd v1.3.x or master, which provides tag functionality.
