Disclousre: I work at Weaveworks


Ajay - IP assignments are managed dynamically by Weave Net.  There is
NO manual intervention needed.  Here are the docs -
http://docs.weave.works/weave/latest_release/features.html#addressing
 Please: If you need help with Weave, get in touch.


All,

I'd like to highlight an important feature of Weave Net that I haven't
seen in competing products.  Weave does not require you to set and up
and manage a distributed key-value store, such as etcd, in order to
maintain network state.  This makes Weave a lot easier to set up.
Also, it means that with Weave you don't lose *any* availability
during a network partition.  Finally, you don't suffer the performance
hit of running a consensus algorithm when you update your network.  A
reasonably good intro to this is here -
http://blog.weave.works/2015/11/03/docker-networking-1-9-technical-deep-dive/

Please do feel free to direct questions about Weave to our team and
community!  See here: http://weave.works/help/index.html#mailing-list

Gladly, Weitao. It'd be my pleasure.

But give me a few hours to find some free time. 

I am today tasked with cooking a Thanksgiving turkey.

But I will try to find the time before noon today (I'm on the right coast in 
the USA).

Have a look at Calico. I found it much easier to deploy in cross domain setup 
and you do not have to worry about networking containers in multihost setup as 
it is pure layer 3 virtual networking.

Re: Anyone try Weave in Mesos env ?

[Paul Bell]

Hi Weitao,

I came up with this architecture as a way of distributing our application
across multiple nodes. Pre-Mesos, our application, delivered as a single
VMware VM, was not easily scalable. By breaking out the several application
components as Docker containers, we are now able (within limits imposed
chiefly by the application itself) to distribute & run those containers
across the several nodes in the Mesos cluster. Application containers that
need to talk to each other are connected via Weave's "overlay" (veth)
network.

Not surprisingly, this architecture has some of the benefits that you'd
expect from Mesos, chief among them being high-availability (more on this
below), scalability, and hybrid Cloud deployment.

The core unit of deployment is an Ubuntu image (14.04 LTS) that I've
configured with the appropriate components:

Zookeeper
Mesos-master
Mesos-slave
Marathon
Docker
Weave

SSH (including RSA keys)

Our application


This images is presently downloaded by a customer as a VMware .ova file. We
typically ask the customer to convert the resulting VM to a so-called
VMware template from which she can easily deploy multiple VMs as needed.
Please note that although we've started with VMware as our virtualization
platform, I've successfully run cluster nodes on both EC2 and Azure.

I tend to describe the Ubuntu image as "polymorphic", i.e., it can be told
to assume one of two roles, either a "master" role or a "slave" role. A
master runs ZK, mesos-master, and Marathon. A slave runs mesos-slave,
Docker, Weave, and the application.

We presently offer 3 canned deployment options:

   1. single-host, no HA
   2. multi-host, no HA (1 master, 3 slaves)
   3. multi-host, HA (3 masters, 3 slaves)

The single-host, no HA option exists chiefly to mimic the original
pre-Mesos deployment. But it has the added virtue, thanks to Mesos, of
allowing us to dynamically "grow" from a single-host to multiple hosts.

The multi-host, no HA option is presently geared toward a sharded MongoDB
backend where each slave runs a mongod container that is a single partition
(shard) of the larger database. This deployment option also lends itself
very nicely to adding a new slave node at the cluster level, and a new
mongod container at the application level - all without any downtime
whatsoever.

The multi-host, HA option offers the probably familiar *cluster-level* high
availability. I stress "cluster-level" because I think we have to
distinguish between HA at that level & HA at the application level. The
former is realized by the 3 master hosts, i.e., you can lose a master and
new one will self-elect thereby keeping the cluster up & running. But, to
my mind, at least, application level HA requires some co-operation on the
part of the application itself (e.g., checkpoint/restart). That said, it
*is* almost magical to watch Mesos re-launch an application container that
has crashed. But whether or not that re-launch results in coherent
application behavior is another matter.

An important home-grown component here is a Java program that automates
these functions:

create cluster - configures a host for a given role and starts Mesos
services. This is done via SSH
start application - distributes application containers across slave hosts.
This is done by talking to the Marathon REST API
stop application - again, via the Marathon REST API
stop cluster - stops Mesos services. Again, via SSH
destroy cluster - deconfigures the host (after which it has no defined
role); again, SSH


As I write, I see Ajay's e-mail arrive about Calico. I am aware of this
project and it seems quite solid. But I've never understood the need to
"worry about networking containers in multihost setup". Weave runs as a
Docker container and It Just Works. I've "woven" together slaves nodes in a
cluster that spanned 3 different datacenters, one of them in EC2, without
any difficulty. Yes, I do have to assign Weave IP addresses to the several
containers, but this is hardly onerous. In fact, I've found it "liberating"
to select such addresses from a CIDR/8 address space, assigning them to
containers based on the container's purpose (e.g., MongoDB shard containers
might live at 10.4.0.X, etc.). Ultimately, this assignment boils down to
setting an environment variable that Marathon (or the mesos-slave executor)
will use when creating the container via "docker run".

There is a whole lot more that I could say about the internals of this
architecture. But, if you're still interested, I'll await further questions
from you.

HTH.

Cordially,

Paul

With Calico you only create the virtual subnets and ip assignments are managed

Hi Sam, 

Yeah, I have significant experience in this regard.

We run a Docker containers spread across several Mesos slave nodes. The

Happy Thanksgiving to you, too.

I tend to deploy the several Mesos nodes as VMware VMs.

However, I've also run a cluster with master on ESXi, slaves on ESXi, slave on 
bare metal, and an EC2 slave.

But in my case all applications are Docker containers connected via Weave.

Does your present deployment involve Docker and Weave?

Re: Anyone try Weave in Mesos env ?

[Paul Bell]

HmmI'm not sure there's really a "fix" for that (BTW: I assume you mean
to fix high (or long) latency, i.e., to make it lower, faster). A network
link is a network link, right? Like all hardware, it has its own physical
characteristics which determine its latency's lower bound, below which it
is physically impossible to go.

Sounds to me as if you've got the whole Mesos + Docker + Weave thing
figured out, at least as far as the basic connectivity and addressing is
concerned. So there's not much more that I can tell you in that regard.

Are you running Weave 1.2 (or above)? It incorporates their "fast path"
technology based on the Linux kernel's Open vSwitch (*vide*:
http://blog.weave.works/2015/11/13/weave-docker-networking-performance-fast-data-path/).
But, remember, there's still the link in between endpoints. One can
optimize the packet handling within an endpoint, but this could boil down
to a case of "hurry up and wait".

I would urge you to take this question up with the friendly, knowledgeable,
and very helpful folks at Weave:
https://groups.google.com/a/weave.works/forum/#!forum/weave-users .

Paul

Re: Anyone try Weave in Mesos env ?

[Sam]

Paul,
Happy thanksgiving first. We are using Aws, Rackspace as hybrid cloud env , and 
we deployed Mesos master in AWS , part of Slaves in AWS , part of Slaves in 
Rackspace .  I am thinking whether it works ? And since it got low latency in 
networking , can we deploy two masters in both AWS and Rackspace ? And 
federation ?Appreciated for your reply .

Regards ,
Sam

Paul,
Yup, Weave and Docker.  May I know how did you fix low latency issue over 
Internet ? By tunnel or ?
