Our Real-World Apollo GraphQL Federation Setup with Rover 0.26 and Supergraph on Kubernetes Apollo GraphQL Federation has become the go-to solution for building distributed GraphQL APIs across large teams, letting us break monolithic graphs into manageable subgraphs while presenting a unified schema to clients. When we migrated our production API to this architecture, we leaned heavily on Rover 0.26 for supergraph management and deployed the resulting supergraph to Kubernetes for scalability and reliability. Here’s how we did it, and the lessons we learned along the way. Why Apollo Federation, Rover, and Kubernetes? Before diving into the setup, let’s recap why this stack works for real-world production use: Apollo Federation lets independent teams own their subgraphs without stepping on each other’s toes, with native support for cross-cutting concerns like auth and pagination.…
