devcontainers

You can achieve production parity by creating a devcontainer with docker-compose configurations that include backing services like Postgres, Redis, Kafka, and S3 to run and test your App Platform apps locally.

A devcontainer is a local development environment defined by devcontainer.json that uses docker-compose to mirror production. You need it to iterate faster and catch deployment surprises before pushing App Platform changes.

To add a devcontainer to an existing project, copy the reference devcontainer into your directory, enable and customize COMPOSE_PROFILES in .devcontainer/devcontainer.json, and configure your required backing services.

Yes, devcontainers support testing apps locally with backing services such as Postgres, Redis, Kafka, and S3. These services are configured via docker-compose to ensure your local environment matches production.

The best way to ensure production parity is using reference templates for devcontainers and docker-compose, then following verification steps and best practices to validate dependencies and components for reliable local execution.

Yes, docker-compose is required to define and run the multi-container backing services like Postgres and Redis alongside your app within the devcontainer, ensuring your local setup accurately mirrors production.
