Setup an Oracle Cloud Infrastructure (OCI) Cloud Profile

ScaleGrid allows you to deploy your MySQL, PostgreSQL, Redis™ and MongoDB® database clusters onto your existing Oracle Cloud Infrastructure (OCI) account in your subscribed region.

Identity and Access setup

You need to create an OCI user with API key and then add it into a new OCI group. Then create a tag namespace called ScaleGrid in your home region root tenancy. Moreover, you need to create policy rules in your root compartment and compartment(s) which deploy ScaleGrid database server(s). Finally, you must have at least 1 VCN with a public or private subnet which has a route to Internet and a network security group for creating a cloud profile in ScaleGrid.

Step 1: Setup a user, API key & group for ScaleGrid

Create a user

Steps to create a user:

1. Go to Identity & Security > Users page.

2. Click the Create User button to create a new user.

Add user API key

Before adding the API key, you need to generate an API signing key. Please keep your public and private keys in a safe place. We need both keys in later steps.

Steps to add user API key

1. Login to OCI Console.
2. Select your Home Region.

3. Go to Identity & Security > Users page

4. Click the user that you have created in the previous step.
5. Click API Keys under the Resources section on the bottom left of the page.

6. Click the Add API Key button select the PASTE PUBLIC KEYS radio button then paste your public key into the PUBLIC KEY text area.
7. Click the Add button.
8. Please copy the Fingerprint form the API Keys section. We will need this to create the cloud profile in ScaleGrid.

Create a group

Steps to create a group:

1. Login to OCI Console.
2. Select your Home Region

3. Go to Identity & Security > Groups page.

4. Click the Create Group button to create a new group

Add user to group

Steps to add user into the group:

1. Go to Identity & Security > Groups page.
2. Click the group that you have created in the create group step.
3. Click the Add User to Group button.
4. Select the user that you have created in the create user step then click the Add button.

Step 2: Setup ScaleGrid compartment(s) and tag namespace

Create a compartment

Steps to create a compartment

1. Go to Identity & Security > Compartments page.
2. Click the Create Compartment button.
3. Fill in both Name and Description then select your root compartment.

4. Click the Create Compartment button.

Create tag namespace

You can create the Tag namespace called ScaleGrid in your root tenancy or you can create your own Tag name same in your Compartment.

If the ScaleGrid Tag namespace is created in root tenancy then you must have the following IAM policy.
Allow group <Group name> to use tag-namespaces in tenancy

If you want to define your own Tag namespace in your Compartment then you don’t require the above policy but you need to provide the Tag namespace name during cloud profile creation Step 2 - Access Info.

Steps to create tag namespace

1. Go to Governance & Administration > Tag Namespaces page.

2. Click the Create Namespace Definition button.
3. Fill in the following information in Create Namespace Definition dialog box:
   --Select root compartment (or your Compartment) from CREATE IN COMPARTMENT dropdown.
   --Enter ScaleGrid (or an appropriate name for your Compartment Tag Namespace) in NAMESPACE DEFINITION NAME text box.
   --Enter For ScaleGrid in DESCRIPTION text box.

4. Click the Create Namespace Definition button.
5. Go back to the Tag Namespaces page and click the ScaleGrid tag namespace.

6. Click the Create Tag Key Definition button.
7. Fill in the following information in Create Tag Key Definition dialog box:
   --Enter DBProvider in TAG KEY text box.
   --Enter For ScaleGrid in DESCRIPTION text box.
8. Click the Create Tag Key Definition button.

Step 3: Setup ScaleGrid IAM Policy for Compartment & tag namespace

Optional: Create a root tenancy policy

NOTE: You only need to configure a root renancy policy if you would like to use ScaleGrid with one consistent tag namespace across multiple Oracle compartments. If you want to configure a ScaleGrid Cloud profile only using compartment level policies, you will need to create a unique tag namespace for each compartment you associate with a ScaleGrid Cloud profile.

Steps to create a root tenancy policy

1. Login to OCI Console.
2. Select your Home Region.

3. Go to Identity & Security > Policies page.

4. Select root compartment from COMPARTMENT dropdown in List Scope section.

5. Click the Create Policy button.
6. Fill in the following information:
   --Enter ScaleGrid in the NAME text box.
   --Enter For ScaleGrid in the DESCRIPTION text box.
   --Select your root compartment.
   --Click Show manual editor in Policy Builder box.

You need to have 1 VCN with a public or private subnet which has a route to Internet and a network security group for creating a cloud profile in ScaleGrid.

Create VCN, Subnet and Route using VCN Wizard

The easiest way to create a virtual cloud network (VCN), public & private subnets, and default route is to use OCI console Start VCN Wizard.

Steps to create VCN, Subnet and Route

1. Login to OCI console.
2. Select your region.

3. Go to Networking > Virtual Cloud Networks page.

4. Select your compartment under the List Scope section from the left bottom page.

5. Click the Start VCN Wizard button.

6. Select VCN with Internet Connectivity radio button then click the Start VCN Wizard button.

7. Fill in the VCN name and select your compartment created in the previous step.

8. Click the Next button.
9. Click the Create button.

Subnet Route to Internet

All database clusters’ nodes (VMs) by ScaleGrid must have internet access.
For public subnet, it must have a route rule to the Internet Gateway.
For private subnet, it must have a NAT Gateway.

Steps to check public subnet has route to Internet

1. Go to Networking > Virtual Cloud Networks page.
2. Select your compartment under the List Scope section from the left bottom page.

3. Click your VCN.
4. Click Subnets under the Resources section from the left.

If you don’t have the above route rule then please create an internet gateway and add the route rule to your subnet route table. You can find more details from here.

Steps to check private subnet has route to Internet

1. Go to Networking > Virtual Cloud Networks page.
2. Select your compartment under the List Scope section from the left bottom page.

3. Click your VCN.
4. Click Subnets under the Resources section from the left.

5. Click your private subnet.
6. Click the Route Table link.

You should expect to see a NAT Gateway route rule.

If you don’t have the above route rule then please create a NAT gateway and add the route rule to your subnet route table. You can find more details from here.

Create Network Security Group

Steps to create network security group

1. Go to Networking > Virtual Cloud Networks page.
2. Select your compartment under the List Scope section from the left bottom page.

3. Click your VCN.
