Unable to run Docker Codenvy, "please rerun CLI"

[gc-alexlong]

While trying to troubleshoot another issue for Codenvy, a warning eventually appeared:
WARN: Your 'nightly' image is over 24 hours old - checking for a newer image...

And then after Docker pulled the image, another warning appeared:
WARN: Pulled new 'nightly' image - please rerun CLI

Reproduction Steps:

1. Completely deleted data folder created by codenvy/cli to start from scratch.
2. Ran codenvy/cli again: docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock -v $HOME/dockerprojects/codenvy/data:/data codenvy/cli:nightly start
3. codenvy/cli image is pulled, warning to rerun CLI appeared

Codenvy version: 5.1.0-SNAPSHOT

OS and version: 10.11.6 (El Capitan)

Docker version: 1.12.6

Run --fast to skip this check.

There was an improvement made over the weekend where we now compare the image digest of the nightly that you have on disk to the one that is pulled from Docker Hub. If they are identical, then the CLI continues. If they are not identical, then this message stops.

I am curious as to why your system is thinking that the newly pulled version and the existing one are different digests. I am suspecting that it's because you are on boot2docker. I'd need to access your system to diagnose it specifically.

But it's not a big issue - just append --fast to skip this check.

@gc-alexlong - I just tested the new CLI improvements on Mac, Windows 10, and Linux - they were all ok. I am wondering if being on VirtualBox with Boot2Docker is causing the odd behavior and why the digest detection is not working.

Is there a chance that you have a lot of images on your Docker system and perhaps they are now interfering with them? Can you "docker rmi -f $(docker images -q)" on your system to wipe out all existing Docker images and then rerun? This will make sure that you are starting afresh.

I used the command you just mentioned, removing the images, and that solved the warning messages. Thanks!
