Steeltoe InitializrApi

Steeltoe Initializr API reference implementation

Using the Server

InitializrApi provides 4 REST/HTTP endpoints:

api/
api/about
api/config
api/project

`api/`

api/ accepts GET requests ands returns an InitializrAPI help document. The document includes available parameters (and their defaults) and dependencies, as well as some CLI samples.

$ http -p b https://start.steeltoe.io/api/
...
This service generates quickstart projects that can be easily customized.
Possible customizations include a project's dependencies and .NET target framework.

The URI templates take a set of parameters to customize the result of a request.
+-----------------+-----------------------+----------------------------+
| Parameter       | Description           | Default value              |
+-----------------+-----------------------+----------------------------+
| name            | project name          | Sample                     |
| applicationName | application name      | SampleApplication          |
...

`api/about`

api/about accepts GET requests ands returns InitialzrAPI "About" information.

$ http -p b https://start.steeltoe.io/api/about
{
    "commit": "381bbd2a1e30d621ed6ad4a07790955447ffe468",
    "name": "Steeltoe.InitializrApi",
    "url": "https://github.com/SteeltoeOSS/InitializrApi/",
    "vendor": "SteeltoeOSS/VMware",
    "version": "0.8.0"
}

`api/config`

api/config accepts GET requests and returns InitializrApi configuration.

The returned document includes all configuration. Sub-endpoints are available allowing for more targeted responses.

api/config/projectMetadata can be used by smart clients, such as InitializrWeb, to assist in creating user interfaces.

The following endpoints can be used by CLI users to determine what project configuration options are available:

api/config/archiveTypes
api/config/dependencies
api/config/dotNetFrameworks
api/config/dotNetTemplates
api/config/languages
api/config/steeltoeVersions

# sample: list available Steeltoe versions
$ http -p b https://start.steeltoe.io/api/config/steeltoeVersions
[
    {
        "id": "2.4.4",
        "name": "Steeltoe 2.4.4 Maintenance Release"
    },
    {
        "id": "2.5.1",
        "name": "Steeltoe 2.5.1 Maintenance Release"
    },
    {
        "id": "3.0.1",
        "name": "Steeltoe 3.0.1 Maintenance Release"
    }
]

# sample: list available dependency IDs
$ http https://start.steeltoe.io/api/config/dependencies | jq '.[] .values[] .id' | sort
"actuator"
"amqp"
"azure-spring-cloud"
"circuit-breaker"
"cloud-foundry"
"config-server"
"data-mongodb"
"data-redis"
"docker"
"dynamic-logger"
"eureka-client"
"mysql"
"mysql-efcore"
"oauth"
"placeholder"
"postgresql"
"postgresql-efcore"
"random-value"
"sqlserver"

`api/project`

api/project accepts GET and POST requests and returns a project as an archive.

Projects are configured by using HTTP parameters, such as name for project name and steeltoeVersion for Steeltoe version. The parameter dependencies is a little different than other parameters in that it is set to a comma-separated list of dependency IDs.

To get a list of parameters and dependencies, send a GET request to api/.

# sample: generate a .NET Core App 3.1 project with a actuator endpoints and a Redis backend:
$ http https://start.steeltoe.io/api/project dotNetFramework=netcoreapp3.1 dependencies==actuators,redis -d

Configuring the Server

The Initializr API configuration is a JSON document provided by a Spring Cloud Config Server or a local file. The former is recommended for production deployments; the latter is intended primarily for local development.

Using Spring Cloud Config Server

The Initializr API uses the Steeltoe Config Server Provider to get configuration from a Spring Cloud Config Server.

The InitializrAPI running at https://start.steeltoe.io/api/ uses a Spring Cloud Config Server backended at https://github.com/SteeltoeOSS/InitializrConfig. The following appsettings.json sample snippet is part of the InitializrApi's configuration:

  ...,
  "spring": {
    "application": {
      "name": "SteeltoeInitializr"
    },
    "cloud": {
      "config": {
        "uri": "http://initializr-config-server/"
      }
    }
  },
  ...

See the Steeltoe Config Server Provider documentation for other configuration options.

Using a local file

Note: configuring a local file overrides any Spring Cloud Config Server configuration

The following appsettings.json sample snippet configures the use of a local configuration file:

  ...,
  "Initializr": {
    "Configuration" : {
      "Path": "Resources/config.json"
    }
  },
  ...
