Oracle Cloud Infrastructure Golang SDK

This is the Go SDK for Oracle Cloud Infrastructure. This project is open source and maintained by Oracle Corp. The home page for the project is here.

WARNING:: To avoid automatically consuming breaking changes if we have to rev the major version of the Go SDK, please consider using the Go dependency management tool, or vendoring the SDK. This will allow you to pin to a specific version of the Go SDK in your project, letting you control how and when you move to the next major version.

Dependencies

• Install Go programming language.
• Install GNU Make, using the package manager or binary distribution tool appropriate for your platform.

Installing

Use the following command to install this SDK:

go get -u github.com/oracle/oci-go-sdk

Alternatively you can git clone this repo.

Working with the Go SDK

To start working with the Go SDK, you import the service package, create a client, and then use that client to make calls.

Configuring

Before using the SDK, set up a config file with the required credentials. See SDK and Tool Configuration for instructions.

Once a config file has been setup, call common.DefaultConfigProvider() function as follows:

// Import necessary packages
import (
   "github.com/oracle/oci-go-sdk/common"
   "github.com/oracle/oci-go-sdk/identity" // Identity or any other service you wish to make requests to
)

//...

configProvider := common.DefaultConfigProvider()

Or, to configure the SDK programmatically instead, implement the ConfigurationProvider interface shown below:

// ConfigurationProvider wraps information about the account owner
type ConfigurationProvider interface {
   KeyProvider
   TenancyOCID() (string, error)
   UserOCID() (string, error)
   KeyFingerprint() (string, error)
   Region() (string, error)
}

Making a request

To make a request to an OCI service, create a client for the service and then use the client to call a function from the service.

• Creating a client: All packages provide a function to create clients, using the naming convention New<ServiceName>ClientWithConfigurationProvider, such as NewVirtualNetworkClientWithConfigurationProvider or NewIdentityClientWithConfigurationProvider. To create a new client, pass a struct that conforms to the ConfigurationProvider interface, or use the DefaultConfigProvider() function in the common package.

For example:

config := common.DefaultConfigProvider()
client, err := identity.NewIdentityClientWithConfigurationProvider(config)
if err != nil { 
     panic(err)
}

• Making calls: After successfully creating a client, requests can now be made to the service. Generally all functions associated with an operation accept context.Context and a struct that wraps all input parameters. The functions then return a response struct that contains the desired data, and an error struct that describes the error if an error occurs.

For example:

id := "your_group_id"
response, err := client.GetGroup(context.Background(), identity.GetGroupRequest{GroupId:&id})
if err != nil {
	//Something happened
	panic(err)
}
//Process the data in response struct
fmt.Println("Group's name is:", response.Name)

Organization of the SDK

The oci-go-sdk contains the following:

• Service packages: All packages except common and any other package found inside cmd. These packages represent the Oracle Cloud Infrastructure services supported by the Go SDK. Each package represents a service. These packages include methods to interact with the service, structs that model input and output parameters, and a client struct that acts as receiver for the above methods.

• Common package: Found in the common directory. The common package provides supporting functions and structs used by service packages. Includes HTTP request/response (de)serialization, request signing, JSON parsing, pointer to reference and other helper functions. Most of the functions in this package are meant to be used by the service packages.

• cmd: Internal tools used by the oci-go-sdk.
