Enabling IBM Storage Ceph Dashboard manually

If you have installed an IBM Storage Ceph cluster by using --skip-dashboard option during bootstrap, you can see that the dashboard URL and credentials are not available in the bootstrap output. You can enable the dashboard manually using the command-line interface. Although the monitoring stack components such as Prometheus, Grafana, Alertmanager, and node-exporter are deployed, they are disabled and you have to enable them manually.

Prerequisites

A running IBM Storage Ceph cluster installed with --skip-dashboard option during bootstrap.
Root-level access to the host on which the dashboard needs to be enabled.

Procedure

Log into the cephadm shell:

Example
```
[root@host01 ~]# cephadm shell
```
Check the Ceph Manager services:

Example
```
[ceph: root@host01 /]# ceph mgr services

{
    "prometheus": "http://10.8.0.101:9283/"
}
```
You can see that the Dashboard URL is not configured.

Enable the dashboard module:

Example

[ceph: root@host01 /]# ceph mgr module enable dashboard

Create the self-signed certificate for the dashboard access:

Example
```
[ceph: root@host01 /]# ceph dashboard create-self-signed-cert
```
Note: You can disable the certificate verification to avoid certification errors.

Check the Ceph Manager services:

Example

[ceph: root@host01 /]# ceph mgr services

{
    "dashboard": "https://10.8.0.101:8443/",
    "prometheus": "http://10.8.0.101:9283/"
}

Create the admin user and password to access the dashboard:

Syntax

echo -n "PASSWORD" > PASSWORD_FILE
ceph dashboard ac-user-create admin -i PASSWORD_FILE administrator

Example

[ceph: root@host01 /]# echo -n "p@ssw0rd" > password.txt
[ceph: root@host01 /]# ceph dashboard ac-user-create admin -i password.txt administrator
