Keystone client

Introduction

The openapi folder is generated from keystone.yaml(i.e. the OAS) using openapi-generator-cli.

Another OAS token.json is not used for now because the openapi-generator-cli v5.3.0 does not support object combinations(oneOf, anyOf and allOf), in which case brings too much complexity.

The options parameter in some APIs is not supported.

Build

./build.sh

Note

For openapi-generator-cli does not support oneOf schema, define OneOfstringprojectResponse in model_project_get.go

type OneOfstringprojectResponse interface{}

Usage

Build client by token

// Build client
client, err := keystone.NewDefaultClientByToken("a_keystone_token")
if err != nil {
    panic(err)
}

// API Call
resp, r, err := client.DomainApi.ListDomains(context.TODO()).Execute()

Build client by password

// Build client
client, err := keystone.NewDefaultClient()
if err != nil {
    panic(err)
}

// Authenticate
domain := "default"
scope := model.NewDomainScope(&domain, nil)
user := "drone"
cred := model.NewPasswordCredential(nil, &user, "password", &domain, nil)
response, err := client.Auth.Authenticate(scope, cred)

if err != nil {
    fmt.Printf("%v\n", response)
    fmt.Printf("%v\n", err)
    panic(err)
}
fmt.Println(client.Token)

// API Call
resp, r, err := client.DomainApi.ListDomains(context.TODO()).Execute()

How to change the server configuration?

Default

The client uses the first server (index=0) defined in OAS by default.

- description: Service domain
  url: http://keystone-api.openstack.svc.cluster.local

Change manually in code

Just edit the config object.

config := openapi.NewConfiguration()
config.Servers = openapi.ServerConfigurations{{
    URL:         "localhost:8000",
}}
client, err := keystone.NewClient(config)
