Prerequisites

• Docker
• Docker Compose

Optional:

• Kubernetes
• Helm

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.

When using the Docker Compose files in development the local app folder will be mounted on top of the app folder within the Docker container, hiding the CSS files that were generated during the Docker build. For the site to render correctly locally npm run build must be run on the host system.

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.

• run migrations
  • docker-compose -f docker-compose.migrate.yaml run --rm database-up
• start
  • docker-compose up
• stop
  • docker-compose down or CTRL-C

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 & CD Pipeline

This service uses the ADP Common Pipelines for Builds and Deployments.

AppConfig - KeyVault References

If the application uses keyvault references in appConfig.env.yaml, please make sure the variable to be added to keyvault is created in ADO Library variable groups and the reference for the variable groups and variables are provided in build.yaml like below.

variableGroups: 
    - ffc-sfd-messages-processor-snd1
    - ffc-sfd-messages-processor-snd2
    - ffc-sfd-messages-processor-snd3
variables:
    - ffc-sfd-messages-processor-APPINSIGHTS-CONNECTIONSTRING
