Table of Contents

Project contents

This application has been generated with the following capabilities and services, which are described in full in their respective sections below:

Requirements

Run

To build and run the application:

  1. swift build
  2. .build/debug/UNCmorfiServer

Docker

A description of the files related to Docker can be found in the Docker files setion. To build the two docker images, run the following commands from the root directory of the project:

  • docker build -t myapp-run .
  • docker build -t myapp-build -f Dockerfile-tools . You may customize the names of these images by specifying a different value after the -t option.

To compile the application using the tools docker image, run:

  • docker run -v $PWD:/swift-project -w /swift-project myapp-build /swift-utils/tools-utils.sh build release

To run the application:

  • docker run -it -p 8080:8080 -v $PWD:/swift-project -w /swift-project myapp-run sh -c .build-ubuntu/release/UNCmorfiServer

Configuration

Your application configuration information for any services is stored in the localdev-config.json file in the config directory. This file is in the .gitignore to prevent sensitive information from being stored in git. The connection information for any configured services that you would like to access when running locally, such as username, password and hostname, is stored in this file.

The application uses the CloudEnvironment package to read the connection and configuration information from the environment and this file. It uses mappings.json, found in the config directory, to communicate where the credentials can be found for each service.

If the application is running locally, it can connect to IBM Cloud services using unbound credentials read from this file. If you need to create unbound credentials you can do so from the IBM Cloud web console (example), or using the CloudFoundry CLI cf create-service-key command.

When you push your application to IBM Cloud, these values are no longer used, instead the application automatically connects to bound services using environment variables.

Iterative Development

The iterative-dev.sh script is included in the root of the generated Swift project and allows for fast & easy iterations for the developer. Instead of stopping the running Kitura server to see new code changes, while the script is running, it will automatically detect changes in the project's .swift files and recompile the app accordingly.

To use iterative development:

  • For native OS, execute the ./iterative-dev.sh script from the root of the project.
  • With docker, shell into the tools container mentioned above, and run the ./swift-project/iterative-dev.sh script. File system changes are detected using a low-tech infinitely looping poll mechanism, which works in both local OS/filesystem and across host OS->Docker container volume scenarios.

Service descriptions

Embedded metrics dashboard

This application uses the SwiftMetrics package to gather application and system metrics.

These metrics can be viewed in an embedded dashboard on /swiftmetrics-dash. The dashboard displays various system and application metrics, including CPU, memory usage, HTTP response metrics and more.

Docker files

The application includes the following files for Docker support:

  • .dockerignore
  • Dockerfile
  • Dockerfile-tools

The .dockerignore file contains the files/directories that should not be included in the built docker image. By default this file contains the Dockerfile and Dockerfile-tools. It can be modified as required.

The Dockerfile defines the specification of the default docker image for running the application. This image can be used to run the application.

The Dockerfile-tools is a docker specification file similar to the Dockerfile, except it includes the tools required for compiling the application. This image can be used to compile the application.

Details on how to build the docker images, compile and run the application within the docker image can be found in the Run section.
