Known Knowns

• All not listed products and KITs have not been updated and are based on the release 25.12 or previous releases
  • These products were not part of the testing phase
• The Eclipse Tractus-X release does not include an Identity Wallet. The development team decided on a temporary bridging solution, based on a commercial application, to test and ship the releases 24.08, 24.12, 25.03, 25.06, 25.09 and 25.12. Without implementing this interim solution, participants will not be able to fully utilize this release in consequence.
• For E2E Testing, the 2.2.3 of the SSI DIM Middle Layer was used - this component is FOSS but the currently used wallet (see previous item) is not

BPDM

• Due to last minute vulnerabilties, E2E tests were not executed on the latest code state (#1620 was not covered by E2E tests)
• Due to vulnerabilties present in the base layer, the BPDM images offered in Dockerhub currently contain vulnerabilities

Identity Hub

• The identity hub wallet was not tested with a Tractus-X EDC Connector yet (planned for R26.06) to be fully functional
• The issuer service is not integrated with the portal backend (because of a limitation from the portal for the bring your own wallet topic)
• The wallet currently supports only one issuer (is configuration issue)
• Currently there is not possible to issue the membership credential as defined in the CX-0050 standard from Catena-X, because of a missing feature in upstream: Possible BUG: JWT credential @context is hardcoded and not configurable via CredentialDefinition API
  • Custom Contexts are not allowed, so the "memberOf" key is not possible to be included.

Industry Core Hub

• The notification api is not working for saturn because of a Bug: Backend notifications API is not compatible with Saturn connector. industry-core-hub#529 (which can not be fixed until the end of the release, however is a additional feature)
• Notifications can't be sent via frontend. Currently this is not implemented.
• Digital Product Passport consumption can fail if policy configuration was not made correctly in the connector.

Runtime

The following runtime has been used during end-to-end test:

• Kubernetes version: 1.33.1
• Applications used
  • PostgreSQL version: 15.4.0 or higher
  • DTR version 0.10.0

note

Tractus-X Connector has been tested on both Postgresql versions: 15.x and 16.x

Using helm with central helm registry

You can search all released helm charts with the following commands:

helm repo add tractusx-dev https://eclipse-tractusx.github.io/charts/dev
helm repo update tractusx-dev
helm search repo tractusx-dev --versions

Bitnami changes

The official Bitnami Helm chart repository has been deprecated or is no longer maintained in its previous location. Bitnami has migrated legacy container images to a new repository called bitnamilegacy. Helm charts using Bitnami container images must be updated to reference this new source to ensure continued functionality. With bitnamilegacy we won’t receive security updates.

tip

If you are using a provided helm chart from Eclipse Tractus-X that uses Bitnami container images and it doesn't work, please check the values.yaml file of the respective chart and update/overwrite the image repository from bitnami/<image-name> to bitnamilegacy/<image-name>.

Extract from values.yaml:

postgresql:
  image:
    # -- workaround to use bitnamilegacy chart
    repository: bitnamilegacy/postgresql
    tag: 15.4.0-debian-11-r45

tip

For installation details, please see the referenced Repositories / Releases and related documentation (e.g. migration documentation)
