Cannot connect to ceph cluster: permission denied

[Ben Ye]

Got the erorr from ceph exporter:

2022/03/26 23:11:54 cannot connect to ceph cluster: rados: Permission denied

Configuration file

cat /etc/ceph/ceph.conf
[global]
mon_host = 172.18.146.132:6789,172.18.12.245:6789,172.18.83.88:6789

[client.admin]
keyring = /etc/ceph/ceph.client.admin.keyring

cat /etc/ceph/ceph.client.admin.keyring
[client.admin]
key = AQCNX4pf4T1RLBAA3jJF/Bhc0VcZ9BmGSIKtFA==

I am trying to set up ceph exporter with my rook ceph environment. Can I know how to get the exporter working using existing secrets from rook ceph?

At a glance that looks correct. Some things to try:

1. Is there a newline at the end of the keyring file? IIRC there are issues with parsing keyrings that don't have a newline (or any other character) after the key.
2. Have you tried not specifying the ports for mon_host?
3. Can you try adding the fsid to the ceph configuration file?

Is this problem solved, I have the same problem

version: '2'
services:
  ceph-exporter:
    container_name: ceph-exporter
    restart: always
    image: digitalocean/ceph_exporter
    volumes:
      - /etc/ceph:/etc/ceph
    ports:
      - '9128:9128'

@youzi1030 As you can see above, there are some questions open to the OP that haven't been answered yet.

In general, there's nothing in ceph_exporter that I would expect would cause issues of this kind, so there's something specific about the configuration being provided that's preventing the connection. Can you try some of the things I mention in my post above? That might help illuminate what it is about the Rook config/keyring that is preventing ceph_exporter from connecting.

I have the same problem，doesn't work with docker, but works with binary

[Joshua Baergen]

@yxiaoy6 Which version of Ceph is your cluster using? Which version is installed on the host that you're testing this on?
