The cloud-readiness framework is an open source work-in-progress that provides decoupled management of infrastructure provisioning along with the installation and deployment of the K8ssandra stack in a cloud-specific environment.
Once provisioning and installation is complete, validations (e.g. tests) can be executed for proper inspections of a particular K8ssandra release in a specific cloud environment.
Following the validations, any installations, deployments, or infrastructure can be cleaned up based on the verification scenario defined. All of these activities will be controlled through a set of cloud-agnostic configuration models.
It was important that the cloud-readiness framework could be referenced locally in a Linux machine or as part of CI/CD pipeline. The diagram below describes the framework's flexibilty of running on a user's local Linux or deployed to a centralized test environment.
The cloud readiness framework provides cloud infrastructure provisioning to support test environment setup and execution in the following cloud platforms:
- GCP - in-progress
- AWS - coming soon ...
- Azure - coming soon ...
Terraform modules are used for separation of cloud specific configurations. As such, Terraform commands can be used as normal if needed as the framework exposes those stages of provisioning for maximum flexibility. This flexibility is important for troubleshooting needs or for development of a new version of cloud-readiness modules.
Test cases will utilize the Terraform modules for the cloud-specific platform setup and provisioning. For example when needing a specific cluster, storage, IAM, network settings, etc.
To get started, checkout the repository and follow along in the cloud-readiness user-guide based on your GCP configuration.
Once the test file has your specific settings, issue go test -v from the smoke test folder to kickoff the provisioning activities.
The framework leverages a combination of open source technologies providing the user with flexibility to install the K8ssandra stack, and target tests for execution in a cloud-specific environment.
Following the test executions, the cleanup and teardown can be controlled based on the type of diagnostics needed.
All of these controls are exposed in the cloud-readiness models and used as inputs for test run execution. The models provide sharing and reuse for configurations used across verifications.
Stay tuned as the installation components evolve to support K8ssandra multi-cluster deployments.
