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.
Are you a Developer using the OCI SDK? If so, please fill out our survey to help us make the OCI SDK better for you. Click here for the survey page.
- Install Go programming language, Go1.14, 1.15 and 1.16 is supported By OCI Go SDK.
- Install GNU Make, using the package manager or binary distribution tool appropriate for your platform.
If you want to install the SDK under $GOPATH, you can use go get
to retrieve the SDK:
go get -u github.com/oracle/oci-go-sdk
If you are using Go modules, you can install by running the following command within a folder containing a go.mod
file:
go get -d github.com/oracle/oci-go-sdk/v49@latest
The latest major version (for example v49
) can be identified on the Github releases page.
Alternatively, you can install a specific version (supported from v25.0.0
on):
go get -d github.com/oracle/oci-go-sdk/v49@v49.1.0
Run go mod tidy
In your project, you also need to ensure the import paths contain the correct major-version:
import "github.com/oracle/oci-go-sdk/v49/common" // or whatever major version you're using
To start working with the Go SDK, you import the service package, create a client, and then use that client to make calls.
Before using the SDK, set up a config file with the required credentials. See SDK and Tool Configuration for instructions.
Note that the Go SDK does not support profile inheritance or defining custom values in the configuration file.
Once a config file has been setup, call common.DefaultConfigProvider()
function as follows:
// Import necessary packages
import (
"github.com/oracle/oci-go-sdk/v49/common"
"github.com/oracle/oci-go-sdk/v49/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)
// AuthType() is used for specify the needed auth type, like UserPrincipal, InstancePrincipal, etc. AuthConfig is used for getting auth related paras in config file.
AuthType() (AuthConfig, error)
}
Or simply use one of structs exposed by the oci-go-sdk
that already implement the above interface
To make a request to an Oracle Cloud Infrastructure 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 asNewVirtualNetworkClientWithConfigurationProvider
orNewIdentityClientWithConfigurationProvider
. To create a new client, pass a struct that conforms to theConfigurationProvider
interface, or use theDefaultConfigProvider()
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)
- Expect header: Some services specified "PUT/POST" requests add Expect 100-continue header by default, if it is not expected, please explicitly set the env var:
export OCI_GOSDK_USING_EXPECT_HEADER=FALSE
- Circuit Breaker: By default, circuit breaker feature is enabled, if it is not expected, please explicitly set the env var:
export OCI_SDK_DEFAULT_CIRCUITBREAKER_ENABLED=FALSE
The oci-go-sdk
contains the following:
-
Service packages: All packages except
common
and any other package found insidecmd
. 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
.
