Eleanor Cook engineered and maintained complex infrastructure for the ONSdigital/dp-compose repository, focusing on backend and DevOps workflows. Over five months, she delivered modular Docker Compose stacks supporting legacy publishing, migration, and redirect services, integrating technologies like Redis, MongoDB, and Kafka to enable scalable, testable deployments. Her work included automating build and deployment processes with Makefile and shell scripting, refining onboarding through detailed documentation, and modernizing configuration management using YAML and Infrastructure as Code principles. By expanding service integration and improving local development parity, Eleanor reduced operational friction, enhanced deployment reliability, and ensured maintainable, reproducible environments for publishing workflows.

For 2025-10, delivered end-to-end migration services support in dp-compose, including setup documentation, deployment configuration, and runtime connectivity to MongoDB, driving reproducible deployments and safer data migrations.

September 2025 monthly summary for ONSdigital/dp-compose: What was delivered: - Legacy core publishing stack expansion: integrated new services into the legacy-core-publishing stack, including dis-migration-service, dp-upload-service, dp-dataset-api, and supporting infrastructure (MongoDB, Kafka, ZooKeeper). Docker Compose configurations were updated to include these services and to initialize the required databases/collections. Added LocalStack integration to mirror cloud resources in local environments. Bug fixes: - Corrected a typo in the versions_locks collection name within the MongoDB initialization to ensure accurate schema provisioning. Impact and value: - Enabled faster onboarding of publishing-related services and more reliable data pipelines by expanding the legacy stack and aligning local/development environments with production tooling. This reduces deployment risk and accelerates feature delivery in the publishing domain. Technologies and skills demonstrated: - Docker Compose, microservices orchestration, MongoDB, Kafka, ZooKeeper, LocalStack, and infrastructure provisioning for development and CI environments. Commits contributing to this work: - 4e351b40ae341e54a294072fb035d844cfed8626 (add dis-migration-service to legacy-core-publishing stack) - a7fef6cc4d0e2e384d6b55f1c7a932d2708b8aad (add dp-dataset-api, mongodb, kafka, and zookeeper to legacy-core-publishing stack) - 362e97a5ad645cc06b567ae9c06c76b6e0bef190 (add dp-upload-service and localstack) - d10dac615c442ad16cc55459b2de9f09bc35a1d6 (correct typo)
