Migrations

This document describes breaking changes and migrations between Constellation releases. Use constellation config migrate to automatically update an old config file to a new format.

Migrating from Azure's service principal authentication to managed identity authentication

The provider.azure.appClientID and provider.azure.appClientSecret fields are no longer supported and should be removed.
To keep using an existing UAMI, add the Owner permission with the scope of your resourceGroup.
Otherwise, simply create new Constellation IAM credentials and use the created UAMI.
To migrate the authentication for an existing cluster on Azure to an UAMI with the necessary permissions:
1. Remove the aadClientId and aadClientSecret from the azureconfig secret.
2. Set useManagedIdentityExtension to true and use the userAssignedIdentity from the Constellation config for the value of userAssignedIdentityID.
3. Restart the CSI driver, cloud controller manager, cluster autoscaler, and Constellation operator pods.

Migrating from CLI versions before 2.10

AWS cluster upgrades require additional IAM permissions for the newly introduced aws-load-balancer-controller. Please upgrade your IAM roles using iam upgrade apply. This will show necessary changes and apply them, if desired.
The global nodeGroups field was added.
The fields instanceType, stateDiskSizeGB, and stateDiskType for each cloud provider are now part of the configuration of individual node groups.
The constellation create command no longer uses the flags --control-plane-count and --worker-count. Instead, the initial node count is configured per node group in the nodeGroups field.

Migrating from CLI versions before 2.9

The provider.azure.appClientID and provider.azure.clientSecretValue fields were removed to enforce migration to managed identity authentication

Migrating from CLI versions before 2.8

The measurements field for each cloud service provider was replaced with a global attestation field.
The confidentialVM, idKeyDigest, and enforceIdKeyDigest fields for the Azure cloud service provider were removed in favor of using the global attestation field.
The optional global field attestationVariant was replaced by the now required attestation field.

Migrating from CLI versions before 2.3

The sshUsers field was deprecated in v2.2 and has been removed from the configuration in v2.3. As an alternative for SSH, check the workflow section Connect to nodes.

The image field for each cloud service provider has been replaced with a global image field. Use the following mapping to migrate your configuration:

The enforcedMeasurements field has been removed and merged with the measurements field.
- To migrate your config containing a new image (v2.3 or greater), remove the old measurements and enforcedMeasurements entries from your config and run constellation fetch-measurements
- To migrate your config containing an image older than v2.3, remove the enforcedMeasurements entry and replace the entries in measurements as shown in the example below:
```
measurements:
-    0: DzXCFGCNk8em5ornNZtKi+Wg6Z7qkQfs5CfE3qTkOc8=
+    0:
+        expected: DzXCFGCNk8em5ornNZtKi+Wg6Z7qkQfs5CfE3qTkOc8=
+        warnOnly: true
-    8: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
+    8:
+        expected: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
+        warnOnly: false
-enforcedMeasurements:
-    - 8
