Re: Docker & CEPH-CRASH

I haven't tried it myself but it would probably work to run the crash services apart from cephadm, maybe someone else has a similar setup. Since those are not critical services you can try it without impacting the rest of the cluster. But again, I haven't tried it this way.

Got it: one instance per host is enough.

In my case, I'm not using "ceph orch".
We did it manually,  crafting one docker-compose.yml per host.

The question is:
Is it possible to run a "crash instance" per host or the solution oblige me to adopt the cephadm solution?

Thanks!

Hi,

ceph-crash services are standalone containers, they are not running inside other containers:

host1:~ # ceph orch ls
NAME                           RUNNING  REFRESHED  AGE PLACEMENT                                    IMAGE NAME                                                 IMAGE ID
crash                              4/4  9m ago     3w * mix d2b64e3c3805

Do you see it in your specs? Can you share this output:

ceph orch ls --export --format yaml

You can add the crash service to a spec file and apply it with 'ceph orch apply -i crash-service.yml' where the yml file could look like this:

service_type: crash
service_name: crash
placement:
  host_pattern: '*'

Hey Guys!
I'm running my  entire cluster (12hosts/89osds - v15.2.22) on Docker and everything runs smoothly.

But  I'm kind of "blind" here: ceph-crash is not running inside the containers.
And there's nothing related to "ceph-crash" in the docker logs either....

Is there a special way to configure it?
Should I create and external volume and run a single instance of it?

Thanks!

docker-compose example:

services:
   osd.106:
      container_name: osd106
      image: ceph/daemon:latest-nautilus
      command: osd_directory_single
      restart: unless-stopped
      pid: "host"
      network_mode: host
      privileged: true
      volumes:
        - /dev/:/dev/
        - ../ceph.conf:/etc/ceph
        - ./data/ceph-106/:/var/lib/ceph/osd/ceph-106
