Waiting for head node to initialize... Unable to start on Ubuntu Xenial 16.04.2 LTS

[Ravi K]

trying a single instance setup and have Cassandra running. there seem to be a series of errors during the startup however lack of zookeeper connectivity seems to be the showstopper

appscale up

the controller log is attached. any help will be awesome..

Unfortunately, I'm not able to figure out why ZooKeeper didn't start from the provided log. If you run into this issue again, I would recommend enabling debug-level logs (adding verbose: True in your AppScalefile), and also checking the zookeeper log (/var/log/zookeeper/zookeeper.log).

Thanks chris, will try this again and will post findings.

More general question: what is the best know single-box production
environment to use where appscale will run with absolutely no issues?
The reason I ask is because even though Docker works well for
test/dev, need a persistent datastore that's not tied to the
container's lifecycle.

I would definitely not recommend using AppScale on docker for production. It's probably our least-tested environment.

I would recommend running AppScale on a virtual machine with at least 4GB of memory. We have pre-built images that we've tested, so you don't need to worry about building from scratch (https://www.appscale.com/try-appscale). I tend to use vagrant the most with virtualbox, but our images for AWS, GCE, and Azure are all equally well-tested.

Though AppScale can run on xenial now, I would recommend using trusty for another release for production deployments. Until we've optimized our memory usage a bit more, running all services on a virtual machine with 4GB of memory is a bit tight with xenial.
