Why is the "latest" tag missing or why is it assigned to a Docker image that isn't the last one pushed?

The reason is that you specified a different tag when pushing the image.

The Docker client assigns the latest tag automatically if the Docker image is created and pushed without a tag. You can also specify the latest tag explicitly.

We don't recommend overwriting tags. Use a unique tag for each Docker image version. This way you can use the same Docker image version on all your VMs with identical specifications and more easily identify causes of problems.
