[v0.32.0] - 2023-06-21

Changed

Added

  • [#87] Support for Split-DNS environments

[v0.22.0] - 2023-01-31

Changed

  • [#72] Remove the service environment variables from dogu pods with enableServiceLinks: false in the podspec of the dogu pods. Cluster-aware dogus are generally discouraged to use service link env vars because of security considerations. Instead, the service DNS names should be used to address these services as described in the Kubernetes documentation.
  • Update makefiles to version 7.2.0.
  • Update ces-build-lib to 1.62.0.

[v0.21.0] - 2023-01-11

Fixed

  • [#62] Fix wrong exposed service object key. During the creation of exposed services some wrong object keys are used. Later-on this leads to an error when tried to get these resources.

  • [#59] Support for extended service account definitions in the dogu.json, allowing the creation of kubernetes accounts for dogus.
