Docker Error: push is already in progress

Question

I'm trying to push a container that was interrupted previously by a network drop out. But I get this error:

Error: push rimian/ruby-node-npm is already in progress

But when I run docker ps I don't see anything running.

What shall I do?

Answer 1

Restart the docker service on which you are running the docker. With ubuntu:

sudo service docker restart

Answer 2

Just wait.

I had this once, too, and the problem is that the push is still running in the background, hence you can't do another one.

So just wait, and the problem will disappear automatically after some time.

The fact that you do not see anything running with docker ps is that this command only shows docker containers, not internal docker processes. And pushing an image is not run by a container.
