Sure, Proposal is the right next step. In this email I attached some of recent
proposals discussed here.
Thanks,
Sergey

Hi Sergey,
I went through the guides and the existing drivers Solidfire (
https://github.com/apache/cloudstack/tree/master/plugins/storage/volume/solidfire/src/org/apache/cloudstack/storage/datastore)
and cloudbyte (
https://github.com/apache/cloudstack/tree/master/plugins/storage/volume/cloudbyte/src/org/apache/cloudstack/storage/datastore
).
Shall I start making my proposal?
Any advise on it?
Thank you.

Hello,
I am new to the mailing list, and we are glad to be a part of the CloudStack
community. We are looking to develop plugins and modules that will help grow
and expand the adoption and use of CloudStack. So as part of my introductory
email, I’d like to introduce a little project we have been working on; a
StorageHA Monitor. The Monitor would allow CloudStack and the hosts to test,
communicate and resolve VM availability issues when storage (primary and/or
secondary) availability becomes apparent. This is a small write up about how
it would work:
Consists of two scripts/programs:
The host script runs on the host servers and checks to see if the primary and
secondary storage is available by doing a read/write test then reports to the
master script that runs on the Cloudstack server. The host script will test a
read and a write to the storage every 5 seconds (configurable), and if it
fails 3 times (configurable) then it will be recorded by the master script.
The master script will monitor the results of the host script. If the test is
good, nothing happens and the results are logged and so that we can track the
history of the test results. If the test reports back as failed, then it will
perform the following actions:
· Secondary Storage - It will simply generate and send an alert that the
failure has occurred.
· Primary Storage - The script will perform the following tasks:
o Generate and send an alert that the failure has occurred.
o Force the VMs on that host to shutdown.
o Determine which host to move the VMs to.
o Start the VMs on the healthy host.
We have already started working on some code, and the solution seems to be
testing well. Any thoughts/ideas/input are(is) welcome. Should there are a
solution out there already, then please forgive our ignorance, and point us in
the right direction. We look forward to further collaboration with you all.
Regards,

All,
I would like propose native functionality into CloudStack to provide a
container service through which users out-of-the box can use to launch
container based application. Idea is to support ability to orchestrate the
resources and automate aspects of setting up container orchestrator through
CloudStack. Public IAAS service providers AWS with its ECS [1] and google with
GKE [2] already provides ability container applications. Competitive cloud
orchestration platforms already have native support for container service.
Users of CloudStack both as public cloud providers and users with private
clouds will benefit with such functionality.
While container orchestrator of user choice can be provisioned on top of
CloudStack (with out CloudStack being involved) with tools like TerraForm[3],
Ansible[4] etc, advantage of having native orchestration is giving user a nice
cohesive integration. This proposal would like add a notion of first class
CloudStack entity called container cluster which can be used to provision
resources, scale up, scale down, start and stop the cluster of VM’s on which
containerised applications can be run. For actual container orchestration we
will still need container orchestrator like docker swarm, marathon, kubernetes,
but CloudStack container service can automate setting up of control place
automatically.
Please see the detailed FS [5], and jira ticket [6].

All,
I would like to start discussion on a new feature - Host HA for CloudStack.
CloudStack lacks a way to reliably fence a host, the idea of the host-ha
feature is to provide a general purpose HA framework and HA provider
implementation specific for hypervisor that can use additional mechanism such
as OOBM (ipmi based power management) to reliably investigate, recover and
fence a host. This feature can handle scenarios associated with server crash
issues and reliable fencing of hosts and HA of VM. The first version will have
HA provider implementation for KVM (and for simulator to test the framework
implementation, and write marvin tests that can validate the feature on Travis
and others).
Please have a look at the FS here:
https://cwiki.apache.org/confluence/display/CLOUDSTACK/Host+HA
Looking forward to your comments and questions.
Regards.
