12.3.1 Install Grafana on Compute VM

Create Compute Instance

Go to the Compute Instance creation screen.
Select the image source as the Oracle Linux Cloud Developer Image image from the Oracle Images list.
Oracle Cloud Developer Image has development tools such as OCI CLI already installed.
Create a Compute instance.
Copy the OCID of the created Compute instance.

OCI CLI - Instance Principal Settings

In order to use the OCI API without additional authentication on the Compute instance, you need to set the Instance Principal. The procedure is to add a Compute instance to a Dynamic Group and grant permissions to that Group.

Dynamic Group Settings

Open the navigation menu in the OCI console. Go to Identity & Security > Identity > Dynamic Groups.
Click Create Dynamic Group.
Click Rule Builder on the right side of the rule creation section to add a rule through the tool.
- Matching criteria: Instance OCID
- VALUE: OCID of the copied Compute instance
Enter NAME and DESCRIPTION to create a Dynamic Group.
- Name: Ex) MyInstancePrincipleDynamicGroup

Policy settings

Go to Identity & Security > Identity > Policies.
Click Create Policy.

Create a policy with the following two permissions.

allow dynamic-group <dynamic group you created> to read metrics in tenancy
allow dynamic-group <created dynamic group> to read compartments in tenancy

Policy creation screen

Check OCI CLI connection

Connect to the Compute instance created earlier with SSH.
Connect with the Instance Principal method with the following command. You can check the connection even though the OCI CLI config file is not set.
```
oci os ns get --auth instance_principal
```
- Connection example
```
[opc@mygrafana ~]$ oci os ns get --auth instance_principal
{
  "data": "thekoguryo"
}
[opc@mygrafana ~]$
```

Install Grafana

Connect to the Compute instance and install Grafana by executing the following commands in order.

sudo grafana-cli plugins install oci-metrics-datasource
sudo firewall-cmd --permanent --add-port=3000/tcp
sudo firewall-cmd --reload
sudo systemctl restart grafana-server
