Hello,
I have been trying to deploy an app on a Google Managed VM based on a Node.JS runtime. However, this seems to be a little confused to me as I still get this error while deploying :
ERROR: (gcloud.preview.app.deploy) Not enough VMs ready (0/1 ready, 1 still deploying). Deployed Version: 280815s.386747973874670759
We have been able to deploy it one week ago, so this error does not occur every time (it this reccuring for 2 days now). I guess there is something wrong with our configuration, maybe regarding our app.yaml or our Dockerfile, but I still can't figure out what is going on. Furthermore, the VM is created but is inaccessible, the SSH connection gets lost. I was wondering if this was not coming from Google. Do you have any idea ?
Here is the app.yaml :
module: default
runtime: custom
api_version: 1
vm: true
# manual_scaling:
# instances: 1
# [START scaling]
automatic_scaling:
min_num_instances: 1
max_num_instances: 5
cool_down_period_sec: 60
cpu_utilization:
target_utilization: 0.5
# [END scaling]
health_check:
enable_health_check: False
check_interval_sec: 20
timeout_sec: 4
unhealthy_threshold: 2
healthy_threshold: 2
restart_threshold: 60
handlers:
- url: /.*
script: server.js
Here is the Dockerfile :
FROM google/debian:wheezy
MAINTAINER mchouan#gpartner.eu
# Fetch and install Node.js
RUN apt-get update -y && apt-get install --no-install-recommends -y -q curl python build-essential git ca-certificates
RUN mkdir /nodejs && curl http://nodejs.org/dist/v0.12.0/node-v0.12.0-linux-x64.tar.gz | tar xvzf - -C /nodejs --strip-components=1
# Add Node.js installation to PATH
ENV PATH $PATH:/nodejs/bin
# Install redis
RUN apt-get install -y redis-server
# Install supervisor
RUN apt-get install -y supervisor
# Add Node.js installation to PATH, and set
# the current working directory to /app
# so future commands in this Dockerfile are easier to write
WORKDIR /app
ENV NODE_ENV development
ADD package.json /app/
# RUN npm install
# Adds app source
ADD . /app
ADD supervisord.conf /etc/supervisor/conf.d/supervisord.conf
CMD ["/usr/bin/supervisord"]
Here is the command we run in order to deploy the app :
gcloud preview app deploy $DIR/app.yaml --version="$version" --force
Thank you for helping.

You don't seem to be exposing any ports on the container. For managed VMS, you should expose port 8080, try adding :
EXPOSE 8080
