Re: [ceph-users] Ceph and container

[John Petrini]

I forgot to mention that we are running 2 of our 3 monitors in VM's on our
OSD nodes. It's a small cluster with only two OSD nodes. The third monitor
is on a VM on a separate host. It works well but we made sure the OSD's had
plenty of extra resources to accommodate the VM's and the host OS is
running on SSD. I should also mention that this is a small cluster only
used for non-critical backups which is why we're comfortable with it.

I think you may need to re-evaluate your situation. If you aren't 
willing to spend the $ on 3 Dedicated Servers, is your platform big 
enough to warrant the need for Ceph?

Re: [ceph-users] Ceph and container

[Tomasz Kuzemko]

We are running all Ceph services inside LXC containers with XFS bind
mounts since few years and it works great. Additionally we use macvlan
for networking so each container has it's own IP address without any NATing.

As for Docker (and specifically aufs/overlay), I would advise to test
for data integrity during power outages.

Re: [ceph-users] Ceph and container

[Daniel Gryniewicz]

In addition, Red Hat is shipping a containerized Ceph (all daemons, not 
just mons) as a tech preview in RHCS, and the plan is to support it 
going forward.  We have not seen performance issues related to being 
containerized.  It's based on the ceph-docker and ceph-ansible projects.

No matter what you want to make sure you don't have a single point of
failure. There's not much point it having three monitors if they are all
going to run in containers/VM's on the same host.

Re: [ceph-users] Ceph and container

[John Petrini]

I've had lots of success running monitors in VM's. Never tried the
container route but there is a ceph-docker project
https://github.com/ceph/ceph-docker if you want to give it a shot. I don't
know how highly recommended that it though, I've got no personal experience
with it.

No matter what you want to make sure you don't have a single point of
failure. There's not much point it having three monitors if they are all
going to run in containers/VM's on the same host.

[ceph-users] Ceph and container

[Matteo Dacrema]

Hi,

does anyone ever tried to run ceph monitors in containers?
Could it lead to performance issues?
Can I run monitor containers on the OSD nodes?

I don’t want to buy 3 dedicated servers. Is there any other solution?

Thanks
