Setting `admin` user password for Grafana

By default, cephadm does not create an admin user for Grafana. With the Ceph Orchestrator, you can create an admin user and set the password.

With these credentials, you can log in to the storage cluster’s Grafana URL with the given password for the admin user.

Prerequisites

A running IBM Storage Ceph cluster with the monitoring stack installed.
Root-level access to the cephadm host.
The dashboard module enabled.

Procedure

As a root user, create a grafana.yml file and provide the following details:

Syntax

service_type: grafana
spec:
  initial_admin_password: PASSWORD

Example

service_type: grafana
spec:
  initial_admin_password: mypassword

Mount the grafana.yml file under a directory in the container:

Example
```
[root@host01 ~]# cephadm shell --mount grafana.yml:/var/lib/ceph/grafana.yml
```
NOTE: Every time you exit the shell, you have to mount the file in the container before deploying the daemon.
Optional: Check if the dashboard Ceph Manager module is enabled:

Example
```
[ceph: root@host01 /]# ceph mgr module ls
```
Optional: Enable the dashboard Ceph Manager module:

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

Apply the specification using the orch command:

Syntax

ceph orch apply -i FILE_NAME.yml

Example

[ceph: root@host01 /]# ceph orch apply -i /var/lib/ceph/grafana.yml

Redeploy grafana service:

Example
```
[ceph: root@host01 /]# ceph orch redeploy grafana
```
This creates an admin user called admin with the given password and the user can log in to the Grafana URL with these credentials.

Verification

Log in to Grafana with the credentials:

Syntax
```
https://HOST_NAME: PORT
```
Example
```
https://host01:3000/
```
