This scaffolded application provides a starting point for creating Swift applications running on Kitura.
This application has been generated with the following capabilities and services:
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.
The application includes the following files for Docker support:
.dockerignoreDockerfileDockerfile-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 below.
Your application has a set of cloud deployment configuration files defined to support deploying your application to IBM Cloud:
manifest.yml.bluemix/toolchain.yml.bluemix/pipeline.yml
The manifest.yml defines options which are passed to the Cloud Foundry cf push command during application deployment.
IBM Cloud DevOps service provides toolchains as a set of tool integrations that support development, deployment, and operations tasks inside IBM Cloud, for both Cloud Foundry and Kubernetes applications. The "Create Toolchain" button creates a DevOps toolchain and acts as a single-click deploy to IBM Cloud including provisioning all required services.
Your application configuration information is stored in the config.json in the project root directory. This file is in the .gitignore to prevent sensitive information from being stored in git.
The connection information for any configured services, 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.
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.
To build and run the application:
swift build.build/debug/testswiftproject01
NOTE: On macOS you will need to add options to the swift build command: swift build -Xlinker -lc++
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-toption.
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/testswiftproject01
You can deploy your application to Bluemix using:
You can deploy the application to IBM Cloud using the CloudFoundry command-line:
- Install the Cloud Foundry command-line (https://docs.cloudfoundry.org/cf-cli/install-go-cli.html)
- Ensure all configured services have been provisioned
- Run
cf pushfrom the project root directory
The Cloud Foundry CLI will not provision the configured services for you, so you will need to do this manually using the IBM Cloud web console (example) or the CloudFoundry CLI (cf create-service command)[http://cli.cloudfoundry.org/en-US/cf/create-service.html]. The service names and types will need to match your configuration.
You can also set up a default IBM Cloud Toolchain to handle deploying your application to IBM Cloud. This is achieved by publishing your application to a publicly accessible github repository and using the "Create Toolchain" button below. In this case configured services will be automatically provisioned, once, during toolchain creation.
