FFC Pay Statement Data

Support data integration with Data Warehouse and Future Farming Statement Service

Prerequisites

• Docker
• Docker Compose

Optional:

• Kubernetes
• Helm

Azure Service Bus

This service depends on a valid Azure Service Bus connection string for asynchronous communication. The following environment variables need to be set in any non-production (!config.isProd) environment before the Docker container is started or tests are run.

When deployed into an appropriately configured AKS cluster (where AAD Pod Identity is configured) the microservice will use AAD Pod Identity.

Name	Description
MESSAGE_QUEUE_HOST	Azure Service Bus hostname, e.g. myservicebus.servicebus.windows.net
MESSAGE_QUEUE_PASSWORD	Azure Service Bus SAS policy key
MESSAGE_QUEUE_USER	Azure Service Bus SAS policy name, e.g. RootManageSharedAccessKey
MESSAGE_QUEUE_SUFFIX	Developer initials

Message schemas

All message schemas are fully documented in an AsyncAPI specification.

Running the application

The application is designed to run in containerised environments, using Docker Compose in development and Kubernetes in production.

• A Helm chart is provided for production deployments to Kubernetes.

Build container image

Container images are built using Docker Compose, with the same images used to run the service with either Docker Compose or Kubernetes.

By default, the start script will build (or rebuild) images so there will rarely be a need to build images manually. However, this can be achieved through the Docker Compose build command:

# Build container images
docker-compose build

Start

Use Docker Compose to run service locally.

./scripts/start

The application is intended to run a scheduled cron job. Therefore the process will exit once complete.
A script is provided to execute the process within an already running Docker container.

./scripts/execute

Test structure

The tests have been structured into subfolders of ./test as per the Microservice test approach and repository structure

Running tests

A convenience script is provided to run automated tests in a containerised environment. This will rebuild images before running tests via docker-compose, using a combination of docker-compose.yaml and docker-compose.test.yaml. The command given to docker-compose run may be customised by passing arguments to the test script.

Examples:

# Run all tests
scripts/test

# Run tests with file watch
scripts/test -w

CI pipeline

This service uses the FFC CI pipeline
