Hi,
I am trying to setup Ceph through Docker inside a VM. My host machine
is Mac. My VM is an Ubuntu 18.04. Docker version is 18.09.5, build
e8ff056.
I am following the documentation present on ceph/daemon Docker Hub
page. The idea is, if I spawn docker containers as mentioned on the
page, I should get a ceph setup without KV store. I am not worried
about KV store as I just want to try it out. Following are the
commands I am firing to bring the containers up:
Monitor:
docker run -d --net=host -v /etc/ceph:/etc/ceph -v
/var/lib/ceph/:/var/lib/ceph/ -e MON_IP=10.0.2.15 -e
CEPH_PUBLIC_NETWORK=10.0.2.0/24 ceph/daemon mon
Manager:
docker run -d --net=host -v /etc/ceph:/etc/ceph -v
/var/lib/ceph/:/var/lib/ceph/ ceph/daemon mgr
OSD:
docker run -d --net=host --pid=host --privileged=true -v
/etc/ceph:/etc/ceph -v /var/lib/ceph/:/var/lib/ceph/ -v /dev/:/dev/ -e
OSD_DEVICE=/dev/vdd ceph/daemon osd
>From the above commands I am able to spawn monitor and manager
properly. I verified this by firing this command on both monitor and
manager containers:
sudo docker exec d1ab985 ceph -s
I get following outputs for both:
cluster:
id: 14a6e40a-8e54-4851-a881-661a84b3441c
health: HEALTH_OK
services:
mon: 1 daemons, quorum serverceph-VirtualBox (age 62m)
mgr: serverceph-VirtualBox(active, since 56m)
osd: 0 osds: 0 up, 0 in
data:
pools: 0 pools, 0 pgs
objects: 0 objects, 0 B
usage: 0 B used, 0 B / 0 B avail
pgs:
However when I try to bring up OSD using above command, it doesn't
work. Docker logs show this output:
2019-04-18 07:30:06 /opt/ceph-container/bin/entrypoint.sh: static:
does not generate config
2019-04-18 07:30:06 /opt/ceph-container/bin/entrypoint.sh: ERROR- The
device pointed by OSD_DEVICE (/dev/vdd) doesn't exist !
I am not sure why the doc asks to pass /dev/vdd to OSD_DEVICE env var.
I know there are five different ways to spawning the OSD, but I am not
able to figure out which one would be suitable for a simple
deployment. If you could please let me know how to spawn OSDs using
Docker, it would help a lot.
