Blob Storage

This document covers the guide to integrating your blob storage with TrueFoundry to let you store your artifacts and models.

We support commonly used blob storage listed below:

Connect Blob Storage

To connect a new storage, one needs to follow the following steps:

Navigate to the Integrations page and go to the Blob Storage tab.
Click on the Connect Storage button at the top right corner.
Now add the name of the storage you want to connect. Select the Integration Provider.
Fill in the credentials and storage root according to the selected integration provider.

Connect AWS S3 storage

Follow the steps below to connect S3 storage to TrueFoundry:

Create a S3 bucket.
- Make sure the bucket has lifecycle configuration to abort multipart upload set for 7 days.
- Make sure CORS is applied on the bucket with the below configuration

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "GET",
            "POST",
            "PUT"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": [
            "ETag"
        ],
        "MaxAgeSeconds": 3000
    }
]

You might have the IAM role for truefoundry already created with the name - tfy-<short-region-name>-<name>-platform-role-<xxxyyyzzz>, if not create a new one. You can add the following permission to that role. You can also create a user with the permissions below, generate an access key and secret key and integrate the blob storage via the access and secret keys.

{
    "Sid": "S3",
    "Effect": "Allow",
    "Action": [
        "s3:*"
    ],
    "Resource": [
        "arn:aws:s3:::<YOUR_S3_BUCKET_NAME>",
        "arn:aws:s3:::<YOUR_S3_BUCKET_NAME>/*"
    ]
}

In the region, please provide the region of the blob storage e.g. eu-west-1
Navigate to Integrations > Blob Storage tab and then add your S3 by clicking Connect Storage.

Connect Google GCS

Follow the steps below to connect GCS storage to TrueFoundry:

Create a GCP bucket.
- Make sure to add the lifecycle configurations on the bucket to delete multipart upload after 7 days.
- For this go to GCP bucket -> Lifecycle -> Add a rule
- Select Delete multi-part upload for 7 days
We also need to add the CORS policy to the GCP bucket. Right now adding the CORS policy to the GCP bucket is not possible through the console so for this, we will use gsutil
1. Create a file called cors.json using the below command
```
cat > cors.json <<EOF
[
    {
      "origin": ["*"],
      "method": ["GET", "POST", "PUT"],
      "maxAgeSeconds": 3600
    }
]
EOF
```
1. Attach the above CORS policy to the service account by running the following command using gsutils
```
gsutil cors set cors.json  gs://BUCKET_NAME
```
Create an IAM serviceaccount named tfy-<short-region-name>-<name>-platform-role, if not created before.
- Attach IAM role of Storage Admin to the bucket create above.
Once the IAM serviceaccount is created, make sure to create a key in JSON format.
Navigate to Integrations > Blob Storage tab and then add your GCS by clicking Connect Storage.

Connect Azure Blob Storage

Follow the steps below to connect your Azure blob storage to TrueFoundry:

Create a Azure Storage account in your resource group
1. Instance details - You must Geo-redundant storage to make sure your data is available through other regions in case of region unavailability.
2. Security - Make sure
  1. DISABLE Allow enabling anonymous access on individual containers
  2. ENABLE Enable storage account key access
3. Network access - ENABLE Allow public access from all networks
4. Recovery - You can keep it to default for 7 days.
Create an Azure container inside the above storage account.
Search for CORS from the left panel and for Blob service (optional for File service Queue service and Table Service, only apply the change if you are using them) select the below options
1. Allowed Origins - * or your control plane URL
2. Allowed Methods - GET, POST, PUT
3. Allowed Headers - *
4. Exposed Headers - Etag
5. MaxAgeSeconds - 3600
Collect the following information
1. Standard endpoint - Endpoint of the blob storage Once the container is created we need to get the standard endpoint of the blob storage along with the container which will look something like this. Replace this with your storage account name and the container name.
```
https://*mystorageaccount*.blob.core.windows.net/*mycontainer*/
```
2. Connection string - From the Azure portal in your storage account, head over to the Security + Networking section under Access keys which will contain the Connection String .
Head over to the platform.
1. In the left section in Integrations tab, click on Blob Storage and +Connect Storage
2. Select the Integration Provider as Azure Blob Storage
3. Add the standard endpoint as the storage root
4. Add the Connection string in the Azure Blob Connection String
