AC

• [x] 0) enhance sap-convereged-cloud plan witn possibility to display given ccee regions for given BTP regions. That means KEB must support mapping between a given BTP region e.g. "cf-eu21" and a list of CCEE regions per Landscape. Configuration must be applied here: https://github.tools.sap/kyma/management-plane-config/tree/main/argoenv/keb for all landscapes. https://github.com/kyma-project/kyma-environment-broker/pull/846
  • [x] 0.1) (converted to additional point by @ralikio) Prepare configuration syntax and define behaviour (with corner cases too) present to PO and team - https://github.com/kyma-project/kyma-environment-broker/pull/812, https://github.com/kyma-project/kyma-environment-broker/pull/818, https://github.com/kyma-project/kyma-environment-broker/pull/820
• [x] 1.1) For BTP region cf-ap10 the sap-converged-cloud plan catalog must return ap-au-1 region only:

  "region": {
  "enum": [
          "ap-au-1"
  ],
  "minLength": 1,
  "type": "string"
  }

• [x] 1.2) For BTP region cf-eu20 the sap-converged-cloud plan catalog must return eu-de-1 region only. This is already done, but has old implementation. Must be adjusted.

  "region": {
  "enum": [
          "eu-de-1"
  ],
  "minLength": 1,
  "type": "string"
  }

• [x] 2) Check if /catalog and /createInstance, /updateInstance validates region value - https://github.com/kyma-project/kyma-environment-broker/pull/886
• [x] 3) Adjust documentation - https://github.com/kyma-project/kyma-environment-broker/pull/859
• [x] 4) Documentation update:
  • [x] Prepare an internal release note
  • [x] Update the internal Help Portal documentation:
    • [x] Regions for the Kyma Environment
    • [x] Available Plans in the Kyma Environment
    • [x] Provisioning and Updating Parameters in the Kyma Environment
• [x] 5) ON DEV we have mapping: "cf-eu20-staging "<-> ["eu-de-1"]
• [x] 6) ON STAGE we have mapping: "cf-eu21 "<-> ["eu-de-1", "ap-au-1"]
• [x] 7) ON PROD we have mapping: "cf-eu20"<-> ["eu-de-1"] ; "cf-ap10"<-> ["ap-au-1"]

I have create a simple test to check our options when using github.com/vrischmann/envconfig. Reading the lib's readme I have learnt bout possible parsing mapping as shown in https://github.com/kyma-project/kyma-environment-broker/pull/812. It would work for short lists, however, the longer the lists, the more troublesome its maintenance would be.

We have decided to use functionality from whitelisted eu regions in KEB https://github.com/kyma-project/kyma-environment-broker/tree/main/internal/whitelist.

• [x] A decision has been made with the team that when region from the path is not present then sap-converged-cloud plan is not returned in the schema. https://github.com/kyma-project/kyma-environment-broker/pull/844
• [x] Feature flag is not necessary.
• [x] E2E tests for SKR or in KEB E2E tests https://github.com/kyma-project/kyma-environment-broker/pull/846
