There are many benefits to using Docker containers in CI/CD pipelines, especially for stateful systems like databases. For example, when you run integration tests, each CI job can start the database in an isolated container with a clean state, preventing conflicts between tests. This results in a testing environment that is reliable, consistent, and cost-effective. This approach also reduces latency and improves the overall performance of the CI/CD pipeline because the database is locally accessible.The Linux-based Azure Cosmos DB emulator is available as a Docker container and can run on a variety of platforms, including ARM64 architectures like Apple Silicon. It allows local development and testing of applications without needing an Azure subscription or incurring service costs. You can easily run it as a Docker container and use it for local development and testing:
