Tanka is a Jsonnet-based tool developed by Grafana Labs to improve the deployment and management of Kubernetes infrastructure, offering a more flexible and efficient alternative to YAML. At FOSDEM 2020, Grafana Labs engineers Tom Braack and Malcolm Holmes demonstrated how Tanka simplifies deploying Grafana instances by reducing the complexity and repetition associated with YAML configurations. Jsonnet's features, such as functions, patches, imports, and packages, enable more concise and adaptable configurations, allowing users to manage development and production environments without duplicating code. Tanka supports the creation of shared Jsonnet libraries, facilitating the use of pre-built modules and mixins for various applications, which enhances scalability and collaboration. During the presentation, Holmes provided a practical demo showcasing the streamlined deployment process using Tanka, significantly reducing the time and code required compared to traditional methods. Interested users are encouraged to explore Tanka further through an online tutorial and engage with the Grafana community.
