For example, pushing an image to ECR requires getting a short-lived token from the AWS API.

For simplicity, Mendix recommends using the `mendix-builder` for the service account name, on both GCP and Kubernetes sides.

+### STACKIT Object Storage {#stackit-object-storage}
+
+This basic, dedicated option allows to attach an existing S3-compatible bucket and credentials (access and secret keys) to one or more environments.
+All apps (environments) will use the same bucket and credentials (access and secret keys). However, with this approach, environments share a common storage namespace, which can lead to potential data isolation issues and increased security risks if not managed carefully. 
+Another option is to use a dedicated object storage bucket for each environment.
+
+#### Prerequisites
+
+* A S3-compatible bucket.
+* An Access and Secret key with permissions to access the bucket.
+
+#### Limitations
+
+* Access/Secret keys used by existing environments can only be rotated manually.
+* No isolation between environments using the storage plan if using same bucket for all environments
+* Configuration parameters will not be validated and will be provided to the Mendix app as-is. If the arguments are not valid or there is an issue with permissions, the Mendix Runtime will fail to start the and deployment will appear to hang with **Replicas running** and **Runtime** showing a spinner.
+
+#### Environment Isolation
+
+* The S3-compatible bucket and credentials (access and secret keys) are shared between all environments using this plan.
+* An environment can access data from other environments using this Storage Plan.
+* By creating dedicated bucket for all the environment, isolation between the environment can be achieved.
+
+#### Create Workflow
+
+When a new environment is created, the Mendix Operator performs the following actions:
+
+* Generate a unique prefix based on the environment's name, so that each environment stores files in a separate prefix (directory).
+* Create a Kubernetes secret to provide connection details to the new app environment - to automatically configure the new environment.
+
+#### Delete Workflow
+
+When an existing environment is deleted, the Mendix Operator performs the following actions:
+
+* Delete that environment's Kubernetes blob file storage credentials secret.
+
+#### Configuring the Plan
+
+In the S3 plan configuration, enter the following details:
+
+* **Endpoint** - The S3-compatible bucket's endpoint address, for example `https://object.storage.eu01.onstackit.cloud`.
+* **Access Key** and **Secret Key** - Credentials to access the bucket.
+* **Type** - Specifies if the container can be shared between environments (create an on-demand storage plan); or that the container can only be used by one environment (create a dedicated storage plan). To increase security and prevent environments from being able to access each other's data, select **Dedicated**.
+
+* **IRSA Authentication** - Set to **no**.
+* **Create bucket per environment** - Set to **No**.
+* **Create account (IAM user) per environment** - Set to **No**.
+* **Endpoint** - The S3 bucket's endpoint address.
+* **Access Key** and **Secret Key** - The credentials for the environment user account.
+* **Autogenerate prefix** - Leave it empty
+* **Share bucket between environments** - Specifies if the bucket can be shared between environments (create an on-demand storage plan); Enable this option and  the bucket will be shared between multiple environments.
