hellosb

hellosb is a (near) feature complete reference implementation of the Open Service Broker specification, generated using go-swagger.

Hellosb is designed as a target for integration tests for OSB clients and libraries. Catalogs are injected as a yaml file and the http server can either be embedded within your test framework or run solo.

Feature include:

• custom catalogs injected at runtime
• embeddable http server for automated testing
• global resource parameters to change runtime behaviors

Getting started

Stand-alone

Build the project like any Go project. Dependencies are vendored.

$ go build -o hellosb

Check flags with ./hellosb --help, but a reasonable place to start is:

$ ./hellosb server --host localhost --port 3000

Embedded

The generated server can be embedded and served from any go project. You may, for example, want to run a local server embedded in your test framework.

For example:

swaggerSpec, err := loads.Embedded(api.SwaggerJSON, api.FlatSwaggerJSON)
if err != nil {
    panic(err)
}

catalog, err := api.ParseCatalog(catalogBytes)
if err != nil {
    panic(err)
}

defaultAPI := api.New(swaggerSpec).
    WithCatalog(catalog).
    Configure(nil)

opts := server.Options{
    Host: "localhost",
    Port: 44777,
    API:  defaultAPI,
}

if err := server.New(opts).Serve(); err != nil {
    panic(err)
}

Where catalogBytes is a byte slice. This can either be loaded from a file

file, err := ioutil.ReadFile(path)
if err != nil {
    panic(err)
}

catalogBytes := []byte(file)

or set directly. The latter may be more useful for test framworks.

var catalogBytes = []byte(`{
    "services": [
    ]
}`)

Usage

The default mocks/catalog.json file covers basic-use cases, but you can update it to better meet your needs.

The json matches the catalog specification, and there's a blank catalog template in the mocks directory.

Instance / Binding Parameters

Provisioning behaviors of service instances and binding can be adjusted with global parameters.

Name	Description	Example
opts_provision_duration	Alters the duration of time before a resource is successfully provisioned. A duration string is a decimal number with a unix suffix ("h", "m", "s", etc). Only applicable for async operations. Defaults to 0m.	"30s", "1h15m"

curl -vv -u user:pass http://127.0.0.1:3000/v2/service_instances/123-4?accepts_incomplete=true -d '{
     "service_id": "123-4",
     "plan_id": "123-4",
     "organization_guid": "org-guid",
     "space_guid": "space-guid",
     "parameters": {
                   "opts_provision_duration": "3m"
     }
}' -X PUT -H "X-Broker-API-Version: 2.16" -H "Content-Type: application/json"

Basic Auth

For the time being, basic auth has been disabled so that any username:password pair is valid.

Contributing

Generating API from spec

With the exception of configure_hellosb.go everything in the restapi/ directory is generated with go-swagger.

To generate new API resources:

swagger generate server -f /path/to/swagger.yaml -A hellosb --exclude-main --default-scheme http

Versioning

hellosb tightly couples to Open Service Broker's versioning scheme for major and minor versions. Each tagged hellosb version is generated from the matching servicebroker swagger specification.

Patch versions correspond to bug fixes and dev iterations on hellosb itself.

For example: 2.16.4 will correlate to hellosb's fourth revision implementing servicebroker's tagged 2.16 specification.
