Create an S3 bucket for AWS storage

Amazon Simple Storage Service (Amazon S3) is an object-storage service offering scalability, data availability, security, and performance. You can store and protect any data for data lakes, cloud-native applications, and mobile apps. Read more about S3 and its capabilities here.
To configure an S3 bucket for auditing, see the Auditing topic.
When creating an S3 bucket using the duplocloud_s3_bucket resource in Terraform, a unique identifier is appended to the bucket name to ensure global uniqueness, as AWS requires. This identifier is the AWS account ID, and a prefix with the tenant name (duploservices-<tenant_name>-) is also added. Additionally, for configuring access logs, the default S3 bucket naming convention follows duplo-<INFRA-NAME>-awslogs-<ACCOUNTNUMBER>, facilitating streamlined log management across services and ingress configurations. DuploCloud automatically adds a prefix and a suffix to bucket names to minimize naming conflicts in the global S3 namespace.
In the DuploCloud Portal, navigate to Cloud Services -> Storage.
Click the S3 tab.
Click Add. The Create an S3 Bucket pane displays.
In the Name field, enter a name for the S3 bucket.
In the Region list box, select the region. You can choose Region Tenant, Default Region, or Global Region and specify Other Region to enter a custom region you have defined.
Optionally, select Enable Bucket Versioning or Object Lock. These settings are disabled by default unless you Enable Bucket Versioning Tenant-wide in Tenant Settings. For more information about S3 bucket versioning, see the AWS documentation. It's important to note that while DuploCloud supports enabling versioning, managing versions and the deletion of versioned objects may require manual steps through the AWS console or CLI, especially since DuploCloud's current Terraform operations perform only basic delete operations.
Click Create. An S3 bucket is created.
Enable Bucket Versioning must be selected to use Object Lock. For environments not subject to compliance requirements, consider disabling versioning on buckets to simplify the creation and destruction of development tenants. However, disabling versioning does not delete existing versions.
You can configure the Tenant to enable bucket versioning by default.
In the DuploCloud Portal, navigate to Administrator -> Tenants.
Click on the Tenant name in the list.
In the Settings tab, click Add. The Add Tenant Feature pane displays.
Click Add. The Create an S3 Bucket pane displays.
From the Select Tenant Feature list box, select Default: Enable bucket versioning for new S3 buckets.
Select Enable.
Click Add. Bucket versioning will be enabled by default on the Create an S3 Bucket pane when creating a new S3 bucket.
With this setting configured, all new S3 buckets in the Tenant will automatically enable bucket versioning.
It is advisable to manage SES-specific buckets not managed by DuploCloud independently. Duplo's default bucket policy enforces encryption, which complements SES's automatic encryption for incoming emails.
You should manage your bucket policies if DuploCloud overwrites the custom policy to update an S3 Bucket defined in DuploCloud for SES.
Manage your S3 Bucket by setting managed_policies ignore in the DuploCloud Terraform provider, select Ignore bucket policies in the DuploCloud Portal when creating or editing your S3 Bucket.
You can set specific AWS S3 bucket permissions and policies using the DuploCloud Portal. Permissions for virtual machines, Lambda functions, and containers are provisioned automatically through Instance profiles, so no access key is required in your application code. However, when coding your application, be aware of these guidelines:
Use the IAM role or Instance profile to connect to services.
Only use the AWS SDK constructor for the region.
Set S3 Bucket permissions in the DuploCloud Portal:
In the DuploCloud Portal, navigate to Cloud Services -> Storage.
Click the S3 tab.
From the Name column, select the bucket for which you want to set permissions. The S3 Bucket page for your bucket displays.
In the Settings tab, click Edit. The Edit a S3 Bucket pane displays.
From the KMS list box, select the key management system scope (AWS Default KMS Key, Tenant KMS Key, etc.).
Select permissions: Allow Public Access, Enable Access Logs, or Enable Versioning. To enable access logs, additional configuration may be required, especially when integrating with Kubernetes ingress annotations.
Select an available Bucket Policy: Require SSL/HTTPS or Allow Public Read. To select the Allow Public Read policy, you must select the Allow Public Access permission. To ignore all bucket policies for the bucket, choose Ignore Bucket Policies.
Click Save. In the Details tab, your changed permissions are displayed.
From the S3 Bucket page, you can set bucket permissions directly in the AWS Console by clicking the >_Console icon. You have permission to configure the bucket within the AWS Console session, but no access or security-level permissions are available.
DuploCloud provides the capability to specify a custom prefix for S3 buckets, enhancing naming conventions and organizational strategies. Before adding custom prefixes, ensure the ENABLEAWSRESOURCEMGMTUSINGTAGS property is set to True in DuploCloud by contacting the DuploCloud Support Team using your Slack channel. This setting allows for a more tailored bucket naming approach that can reflect your organization's naming conventions or project identifiers.
Avoid specifying system-reserved prefixes such as duploservices.
In the DuploCloud Portal, navigate to Administrator -> System Settings.
Click the System Config tab.
Click Add. The Add Config pane displays.
From the Config Type list box, select AppConfig.
From the Key list box, select Prefix all S3 Bucket Names.
In the Value field, enter the custom prefix.
Click Submit.
When attempting to delete S3 buckets, it's crucial to first empty the bucket. DuploCloud is planning to introduce a "force delete data" feature to simplify this process, including version deletions. Until then, manual deletion through the AWS console is a reliable method for smaller buckets. For managing versions, users may need to use the AWS CLI, as DuploCloud's Terraform operations currently only perform basic delete operations.
You can create S3 bucket replication rules for AWS from within the DuploCloud Portal. These rules allow you to automatically replicate objects across buckets, either within the same region or across different regions. Multiple replication rules are supported.
To create an S3 bucket replication rule in DuploCloud, follow these steps:
From the DuploCloud Portal, navigate to Cloud Services -> Storage.
Select the S3 tab.
In the NAME column, click the name of the bucket you want to create the replication rule for.
Select the Replication Rule tab, and click Add. The Add S3 Bucket Replication pane displays.
In the Add S3 Bucket Replication pane, complete the following fields:
Rule Name: Enter a descriptive name for the replication rule.
Tenants: Select the tenant to associate with the replication rule.
Destination S3 Bucket: Choose the destination bucket where the objects from the source bucket will be replicated. This can be in the same or a different AWS region.
Priority: Set the priority for this rule. The lower the number, the higher the priority.
Optionally, enable Delete Marker Replication: this option replicates delete markers from the source bucket to the destination bucket.
Optionally, enable Change Storage class for replicated objects: Enable this option if you want to change the storage class of the replicated objects. Then, select the desired Storage Class (e.g., Standard, Glacier, etc.).
Click Save to apply the replication rule.
From the DuploCloud Portal, navigate to Cloud Services -> Storage.
Select the S3 tab.
In the NAME column, click the name of the bucket you want to view replication rules for.
Select the Replication Rule tab. The replication rules applied to the selected S3 bucket are displayed.
