Can we ban techcrunch please? http://googlecloudplatform.blogspot.com/2014/11/google-cloud...

We're unlikely to ban TechCrunch, but are happy to change urls to more substantive articles when you and other users point them out.

Earlier quoted context omitted.

GCE doesn't support nested virtualization. But if you are running Kubernetes on bare metal, there is no reason you couldn't map in /dev/kvm and have k8s run VMs for you. I haven't done it though :)

Ok, I've done VMs inside docker already which has been fine, was hoping GCE would let me do it on Google's systems.

As someone who doesn't know, why would you want to run VMs inside of a docker container? Wouldn't this have tremendous overhead relative to just running the hypervisor?

Can someone explain the difference between Apache Mesos, Apache Spark, and Kubernetes. As someone reading just announcements, and having never experimented with any of these tools, they sound like they promise the same capabilities. Is it just that they are different open source projects aiming for the same goal ... or are their goals different?

Apache Mesos is based on Twitter's expertise in deploying their cluster, Kubernetes on Google's. They do things in different ways. Spark seems to be in the same area as Hadoop, so not relevant to the conversation.

No. Apache Mesos was originally developed at the UC Berkeley AMPLab as a research project. Twitter was a very early adopter, who subsequently hired the Mesos author/creator.

More info/docs here: https://cloud.google.com/container-engine/ I'm on the Kubernetes/GKE team and happy to answer any questions you all might have. We also all hang out on IRC at #google-containers on freenode.

Some google-managed base images would be helpful. The last time I checked, some of the major public docker images were still shellshock-vulnerable. Pre-installed GCE tools would be helpful. Perhaps automated environment variables about region, etc.

Which?

See https://gist.github.com/voltagex/582473e3b86ee5ae4438 - I ran some tests on the three most popular (?) official base images.

If you use the -privileged flag, docker containers can access /dev/kvm and start low-overhead KVM instances.

It's advantageous for me, because I can say "hey check out this software" and they just have to run a single docker command, compared to installing Go, apt-getting a bunch of packages, fetching our repo, compiling, etc.

Docker has pulled off some really impressive biz dev. I can't think of too many other things that Azure, Google Cloud, and AWS all support.

Strongly agree with this. I've been interviewing for DevOps jobs and it seems like everyone thinks they need to be using Docker for some reason or another. Studying up on it has improved my interview feedback substantially.

If you have found an official Docker image that is still shellshock vulnerable, the library maintainers [1] would love to hear from you as they take that stuff quite seriously. As far as I know the entire library is fully patched.

I hope this have the ripple effect of allowing enterprises to feel comfortable using things like Firebase and Docker. I floated the idea of using Docker but the idea was turned down because we have no idea how it affects performance in a production environment.
