I am looking into documentation for running hydra on a single node remotely. I am looking for methods where I can run a code present in my local machine and to run it on a GCP instance.
Any pointers?
It sounds like you are looking for a Hydra Launcher that supports GCP.
For now, Hydra does not support this. We do have a Ray Launcher that launches to AWS and could be further extended to launching on GCP. Feel free to subscribe this issue.
Working on creating an OpenStack environment under Fuel for 18 XenServer based physical servers based on some prior development work which started with 4 physical servers. In the original configuration, there was only one OpenStack controller. Due to the XenServer hypervisor requirement, the images have to be custom massaged. This induced the developers to use the OpenStack CLI client and the glance image-create command for image installation, vs. using the Fuel Horizon dashboard GUI.
I'm adding at least two other controllers as recommended by best practices.
The question is pretty generic, I hope.
When using the OpenStack client CLI glance command, you set up the environment for communication purposes. Does the glance command in this configuration create the image on ALL controllers or just one?
When I look at the available images via the Fuel Horizon dashboard, the newly created image IS available. My concern is whether it is on all of the controllers? And if not, is there a way to level set all of the controllers WRT images?
Thank you for your time,
Ed Kiefer
If you have two controllers (and one Openstack region) configured properly. You should only ever need to upload the image once. If it is only available from one controller, something with your setup is wrong.
Objective : My objective is to generate a report with all the VMs running on the openstack instance (from all projects) with its flavor size. My Environment is running Red hat openstack OSP 8 (Liberty).
Question/Issue: Is there a way to get the server and its flavor size from all projects? We can get the server list from all projects using OpenStack server "openstack server list --all-projects" but this does not give the flavor size of each VM.
I thought of writing a simple for loop taking the server list output and passing it to openstack server show command but the server show command does not show details from other projects,it only shows for admin.
Basically, I need the report similar to the table in "Horizon -> System -> Instances" (dashboard/admin/instances/) which shows the instances from all projects. I would prefer to stick with cli tools to generate the info.
Appreciate any pointers.
I got it working using nova cli "nova list --fields name,flavor --all-tenants". I could not find any options to list flavor using openstack unified cli.

So I recently discovered this awesome tool, and it says
Docker is an open-source project to easily create lightweight,
portable, self-sufficient containers from any application. The same
container that a developer builds and tests on a laptop can run at
scale, in production, on VMs, bare metal, OpenStack clusters, public
clouds and more.
Let's say I have a docker image which runs Nginx and a website connects to external database. How do I scale the container in production?

First of all thanks for those who have upvoted this answer over the years.
Please be aware that this question was asked in August 2013, when Docker was still a very new technology. Since then: Kubernetes was launched on June 2014, Docker swarm was integrated into the Docker engine in Feb 2015, Amazon launched it's container solution, ECS, in April 2015 and Google launched GKE in August 2015. It's fair to say the production container landscape has changed substantially.
The short answer is that you'd have to write your own logic to do this.
I would expect this kind of feature to emerge from the following projects, built on top of docker, and designed to support applications in production:
flynn
deis
coreos

Jelastic is a hosted PAAS service that scales containers automatically.
Deis automates scaling of Docker containers (among other things).
Deis (pronounced DAY-iss) is an open source PaaS that makes it easy to deploy and manage applications on your own servers. Deis builds upon Docker and CoreOS to provide a lightweight PaaS with a Heroku-inspired workflow.
Here is the developer workflow:
deis create myapp # create a new deis app called "myapp"
git push deis master # built with a buildpack or dockerfile
deis scale web=16 worker=4 # scale up docker containers
Deis automatically deploys your Docker containers across a CoreOS cluster and configures the Nginx routers to route requests to healthy Docker containers. If a host dies, containers are automatically restarted on another host in seconds. Just browse to the proxy URL or use deis open to hit your app.
Some other useful commands:
deis config:set DATABASE_URL= # attach to a database w/ an envvar
deis run make test # run ephemeral containers for one-off tasks
deis logs # get aggregated logs for troubleshooting
deis rollback v23 # rollback to a prior release
To see this in action, check out the terminal video at http://deis.io/overview/. You can also learn about Deis concepts or jump right into deploying your own private PaaS.
You can try Tsuru. Tsuru is a opensource PaaS inspired in Heroku, and it is already with some products in production at Globo.com(internet arm of the biggest Broadcast Television Company in Brazil)
It manages the entire flow of an application, since the container creation, deploy, routing(with hipache) with many nice features as docker cluster, scaling of units, segregated deploy, etc.
Take a look in our documentation bellow:
http://docs.tsuru.io/
Here our post covering our environment:
http://blog.tsuru.io/2014/04/04/running-tsuru-in-production-scaling-and-segregating-docker-containers/
Have a look at Rancher.com - it can manage multiple Docker hosts and much more.
A sensible approach to scaling Docker could be:
Each service will be a docker container
Intra container service discovery managed through links (new feature from docker 0.6.5)
Containers will be deployed through Dokku
Applications will be managed through Shipyard which in its turn is using hipache
Another docker open sourced project from Yandex:
cocaine
Openshift guys also created a project. You can find more information here, try test container and detailed info here .
The only problem is the solution is Redhat centric for now :)
While we're big fans of Deis (deis.io) and are actively deploying to it, there are other Heroku like PaaS style deployment solutions out there, including:
Longshoreman from the Wayfinder folks:
https://github.com/longshoreman/longshoreman
Decker from the CloudCredo folks, using CloudFoundry:
http://www.cloudcredo.com/decker-docker-cloud-foundry/
As for straight up orchestration, NewRelic's opensource Centurion project seems quite promising:

Take a look also at etcd and Consul.

One option not mentioned in other posts is Helios. It is built by spotify and does not try to do too much.

I have setup my openstack dev environment. Now i want to write hello world program (for example i want to write a hello world program in a file say test and when i run nova-manage test it should print Hello World). i looked into web for programming guide, all i found was installation and admin manual. I even went through question openstack Hello World , wasn't helpful. I could use some help...
thanks in advance..
So by openstack dev environment I assume you mean something like devstack ( devstack.org ).
And by openstack I assume ( since you referenced nova-manage ) you are using the nova component of openstack.
nova is a cloud compute controller. it effectively acts as an API for managing virtual machines. Usually in linux this means kvm or xen hypervisor enabled virtual machines. But it is not constrained to this.
By default devstack uses kvm as it's hypervisor of choice.
Openstack will allow you to launch 'instances' once you have loaded images into the glance imagestore. These images function like templates for virtual machines. When you launch an instance based off an existing image you will receive a running virtual machine within your project in openstack. You can ssh to that instance and use it just like any other linux box if the image you are using is a linux image.
Ubuntu cloud services have a list of available images that are compatible with glance and can be freely downloaded.
So... at this point in the explanation I have to assume you think that openstack is something like cloud foundry. It is not. Nova provides IaaS solutions. Infrastructure as a Service. Not PaaS / SaaS as something like cloud foundry would.
Does this make sense?
