# Oracle Cloud Infrastructure S3 for blob store

## post by yves.bationo on Oct 18, 2021

Hi All,

is it possible to use OCI S3 instead of AWS S3 to configure blob stores ?

You can try it, but we don’t test or support anything but AWS S3.

Hi Yves,

From Sonatype’s point of view, the answer is “no”. Unfortunately, in our experience, we had issues with some implementations that claim to be S3-compatible but later caused some issues for us, which led us to state this explicitly on the [System Requirements](https://help.sonatype.com/repomanager3/installation/system-requirements#SystemRequirements-FileSystems) page. You may still try it for yourself, but you’ll be on your own and even if you’ve got the Pro support agreement with us, we won’t be able to help you resolve any issues with the file system.

Hi !

Is there an example of configuration of your OCI? [@yves.bationo](https://community.sonatype.com/u/yves.bationo)

A couple of years later now, any work done or plan to support OCI from Nexus?

## On the OCI side:

1. Go to your profile and create a **Customer Secret Key**:

[OCI Documentation – Create a Customer Secret Key](https://docs.public.content.oci.oraclecloud.com/en-us/iaas/Content/Identity/access/to_create_a_Customer_Secret_key.htm)

You will now have your **Access Key** and **Secret Key**.

2. Create a new **bucket** in any compartment and note its name.

3. In the bucket details, locate the **namespace** — this will be needed later.

4. Identify the **region** where your bucket is located.

## On the Nexus side:

1. Go to **Settings > System > Capabilities**.
2. Click **Create capability** and select **Custom S3 regions**.
3. In the **Regions** field, enter the following list:

Default,us-east-1,us-east-2,us-west-1,us-west-2,us-gov-west-1,us-gov-east-1,eu-west-1,eu-west-2,eu-west-3,eu-central-1,eu-central-2,eu-north-1,eu-south-1,eu-south-2,ap-east-1,ap-southeast-1,ap-southeast-2,ap-southeast-3,ap-southeast-4,ap-northeast-1,ap-northeast-2,ap-northeast-3,ap-south-1,ap-south-2,sa-east-1,ca-central-1,cn-north-1,cn-northwest-1,me-south-1,me-central-1,il-central-1,ca-west-1,af-south-1,us-iso-east-1,us-isob-east-1,us-iso-west-1,my-region

> Replace `my-region` with your actual OCI region.

4. Click **Create** to add the capability.
5. Go to **Settings > Repository > Blob Stores** and click to **Create blob store** using **S3**.

- **Name**: (any name you choose)
   - **Region**: your OCI region
   - **Bucket**: the name of your OCI bucket
   - **Prefix**: (optional)
   - **Authentication**:
     - **Access Key ID**: your OCI Access Key
     - **Secret Access Key**: your OCI Secret Key
   - **Advanced connection settings**:
     - **Endpoint URL**:
       ```css
       https://{object-storage-namespace}.compat.objectstorage.{region}.oraclecloud.com
       ```
     - **Use path-style access**: (checked)

6. Click **Save**. Your blob store is now configured.
