Unable to run ManagedVM Python tutorial on GCloud 0.9.68/Docker 1.7.1/app-engine-python 1.9.23

[ingo]

Hi,

I have been following the tutorial on Managed VMs in the docs. I installed boot2docker 1.7.1 on MacOSX 10.10.1. I confirmed that the installation was successful by running boot2docker run hello-world as described on https://docs.docker.com/installation/mac/. 

However, running gcloud preview app run ./app.yaml and gcloud preview app deploy ./app.yaml fails with an exception:

$ gcloud preview app run ./app.yaml

I have set the DOCKER environment variables in my .bash_profile

export DOCKER_HOST=tcp://192.168.59.103:2376

export DOCKER_CERT_PATH=/Users/ingo/.boot2docker/certs/boot2docker-vm

export DOCKER_TLS_VERIFY=1

.. and docker is running

$ boot2docker status

running

Is there an incompatibility between Docker 1.7.1 and the latest version of GCloud? Or am I missing some important piece of configuration to get this going?

Thanks,

Ingo

Downgrade to the previous Docker version. I already filed a bug about it some minute ago.

Google just updated the documentation on this. You can use the Cloud SDK with 1.7.0 of boot2docker. However, you have to use the following command to download the 1.7.0 ISO (instead of just grabbing the latest version).

boot2docker download --iso-url=https://github.com/boot2docker/boot2docker/releases/download/v1.7.0/boot2docker.iso

Thanks,

The fix suggested to have a downgrade to 1.7.0 instead worked for my nodejs custom app engine VM (just wanted to confirm that it worked).

Though after download, executing "boot2docker version" kept saying "1.7.1" where the ISO was indeed 1.7.0 -- just saying in case that can throw ppl off.
