A hands-on walkthrough for building a GraphQL server that wraps the Docker REST API using Apollo Server and TypeScript. Covers setting up the server to communicate with the Docker daemon via UNIX socket, writing GraphQL type definitions for Docker resources (services and containers), building resolvers that translate GraphQL queries into Docker API REST calls, composing schemas with makeExecutableSchema, and generating TypeScript types from the schema using graphql-code-generator. The key benefit demonstrated is replacing multiple REST calls with a single GraphQL query to fetch services and their related containers.
