Here we go again – welcome 1.3.0
The May release aka version 1.3.0 of the Terraform provider for SAP BTP is out. Let’s look at what has been added since the last release.
Of course, you also find all the information in the release notes in the GitHub repository:
Features: Authenticating via SSO (Single Sign-on) for local execution
One feature requested by the community was to make the local experience more convenient and support SSO for authentication.
In release 1.3.0 this feature is now enabled. It is important to note that we support this feature for local testing only. It is not intended to be used e.g., in CI/CD pipelines.
If you want to make use of this feature, you must set the environment variable “BTP_ENABLE_SSO” to true. The provider evaluates this environment parameter and will trigger browser based SSO login flow as you already know it from the BTP CLI. Be aware that a typical flow executes several logins so do not be surprised if the browser pops up more than once when executing e.g., a “terraform apply”.
Improvements: Readable Error messages for service instance creation
The creation of service instances can be a challenge when it comes to the provisioning of the right parameters. If a provisioning of a service instance fails, the error message should support you in finding the cause of it.
With this release, we improved the returned error message in these scenarios by propagating the human-readable description of the error returned by the service broker to the provider. If such a description is provided by the corresponding service, this should help you in finding the root cause when a service instance creation or update fails.
To give you an impression, here is an example of how the error message looked like when the creation of a HANA Cloud instance. We first create a valid setup via:
Next, we change the parameters by providing an invalid value for the memory:
In release 1.2.0 this results in the following error message
In release 1.3.0 you will see more information that helps you to pin down the root cause (if the service provides this message):
Improvement: Documentation
There is always room for improvement when it comes to the documentation and with this making the consumption of the provider easier. In this release we delivered improvements to two areas:
- Required role collection per resource and data source: the documentation of the resources and data sources now describes which role collection(s) are needed to execute the corresponding Terraform artefact. This makes your Life easier e.g., when creating a technical user for Terraform setups and assigning the necessary role collections to the user to execute the setup tasks.
- Support of drift and import: To make it easier for you to evaluate what is possible when it comes to implementing imports and configuration drift detection, we created some overview pages that allow you to identify immediately which resources can be imported (or if there are restrictions) and for which resources you can implement a drift detection out of the box.
These lists can change over time, updates will be announced in the release notes.
Fix: Handling of state in service instance creation and update
With this release we also fixed a bug in the handling of the service instance creation and update process. If you created or updated a service instance with invalid JSON parameters, the provider persisted the new/changed JSON parameters in the state although the operation failed. A consequent “terraform plan” would have shown that everything is okay although the new parameters have not been applied to the service instance. This behavior is fixed and after a failed operation for a service instance resource the terraform plan operation delivers the expected results.
How to update?
The update of the provider version is straightforward. Depending on your configuration in the provider, you must adjust the version constraint to 1.3.0 and execute a “terraform init -upgrade”.
That’s it.
You find the documentation of the enhanced resources in the Terraform registry: https://registry.terraform.io/providers/SAP/btp/latest
Feedback, questions, bugs, feature requests
The procedure hasn’t change: if you want to interact with us, use the GitHub repository https://github.com/SAP/terraform-provider-btp:
- To file a bug, please open an issue in the repository.
- To file a feature request, please file it in the repository.
- If you have a question, want to discuss ideas, or do some “show & tell”, feel free to start a GitHub Discussion.
There are also some feature requests open that you can vote for. Check for the issues that are label as “enhancement” and “pending decision“ via this link https://github.com/SAP/terraform-provider-btp/issues?q=is%3Aopen+is%3Aissue+label%3Aenhancement+labe....
What else?
Besides the pure technical development mentioned above, we have also been busy in other areas that we want to highlight:
- The Terraform provider, although 100% open source, is now also part of the official SAP documentation on help.sap.com describing how to administer SAP BTP with Infrastructure as Code. You find the details following this link: https://help.sap.com/docs/btp/sap-business-technology-platform/account-administration-using-infrastr...
- We added a new contribution to the Terraform samples repository showcasing how to import resources via the Terraform import mechanism. This is especially interesting if you want to bring existing SAP BTP subaccounts under the management of Terraform.
You find the sample and a detailed description following this link https://github.com/SAP-samples/btp-terraform-samples/tree/main/released/import - Over the course of the last weeks, we wrote some blog posts (including sample code) for scenarios that go a bit beyond the pure provisioning of resources but can be realized via the Terraform provider for SAP BTP already today, e.g., leveraging backstage as developer platform, implementing drift detection, and leveraging the Open Policy Agent to safeguard configuration updates via Terraform. You find the links to the blog posts on these automation scenarios with Terraform following this link: https://community.sap.com/t5/technology-blogs-by-sap/terraform-scenarios-beyond-provisioning-resourc...
What is next?
Do you want a sneak peek at what is coming next and when we plan to deliver the next release? You find that information in the milestones on our GitHub repository https://github.com/SAP/terraform-provider-btp/milestones.
Be aware that plans and dates might change through the course of development.
With that … happy Terraforming!
