IBM Cloud VPC Go SDK Version 0.2.0

Go client library to interact with the various IBM Cloud VPC Services APIs.

Note As IBM continues to invest and innovate on the IBM Cloud Virtual Private Cloud (gen 2 compute) infrastructure, we're focusing on delivering maximum value in a single VPC Infrastructure platform. To support this effort, generation 1 compute infrastructure is being deprecated. The end of service date is 26 February 2021. For more information, see the Start your migration blog.

Overview

The IBM Cloud VPC Go SDK allows developers to programmatically interact with the following IBM Cloud services:

Service Name	Package name
VPC	vpcv1
VPC Gen 1	vpcclassicv1

Prerequisites

• An IBM Cloud account.
• An IAM API key to allow the SDK to access your account. Create one here.
• Go version 1.12 or above.

Installation

There are a few different ways to download and install the VPC Go SDK services for use by your Go application:

go get command

Use this command to download and install the VPC Classic Go SDK service to allow your Go application to use it:

go get -u github.com/IBM/vpc-go-sdk/vpcv1

To install VPC Classic Go SDK service, use the following.

go get -u github.com/IBM/vpc-go-sdk/vpcclassicv1

Go modules

If your application is using Go modules, you can add a suitable import to your Go application, like this:

import (
	"github.com/IBM/vpc-go-sdk/vpcclassicv1"
	"github.com/IBM/vpc-go-sdk/vpcv1"
)

then run go mod tidy to download and install the new dependency and update your Go application's go.mod file.

dep dependency manager

If your application is using the dep dependency management tool, you can add a dependency to your Gopkg.toml file. Here is an example:

[[constraint]]
  name = "github.com/IBM/vpc-go-sdk/"
  version = "0.2.0"

then run dep ensure.

Using the SDK

Setting up VPC service

A quick example to get you up and running with VPC Go SDK service in Dallas (us-south) region.

For other regions, Refer API Endpoints for VPC and update the URL variable accordingly.

Refer to the VPC Release Notes document to find out latest version release.

package main

import (
	"log"
	"os"

	"github.com/IBM/go-sdk-core/v4/core"
	"github.com/IBM/vpc-go-sdk/vpcv1"
)

func main() {
	apiKey := os.Getenv("IBMCLOUD_API_KEY")
	if apiKey == "" {
		log.Fatal("No API key set")
	}

	// Instantiate the service with an API key based IAM authenticator
	vpcService, err := vpcv1.NewVpcV1(&vpcv1.VpcV1Options{
		Authenticator: &core.IamAuthenticator{
			ApiKey: apiKey,
		},
	})
	if err != nil {
		log.Fatal("Error creating VPC Service.")
	}

	// Retrieve the list of regions for your account.
	regions, detailedResponse, err := vpcService.ListRegions(&vpcv1.ListRegionsOptions{})
	if err != nil {
		log.Fatalf("Failed to list the regions: %v and the response is: %s", err, detailedResponse)
	}
	log.Printf("Regions: %#v", regions)

	// Retrieve the list of vpcs for your account.
	vpcs, detailedResponse, err := vpcService.ListVpcs(&vpcv1.ListVpcsOptions{})
	if err != nil {
		log.Fatalf("Failed to list vpcs: %v and the response is: %s", err, detailedResponse)
	}
	log.Printf("VPCs: %#v", vpcs)

	// Create an SSH key
	sshKeyOptions := &vpcv1.CreateKeyOptions{
		Name: core.StringPtr("my-ssh-key"),
	}
	// Setters also exist to set fields are the struct has been created
	sshKeyOptions.SetPublicKey("ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDsnrSAe8eBi8mS576Z96UtYgUzDR9Sbw/s1ELxsa1KUK82JQ0Ejmz31N6sHyiT/l5533JgGL6rKamLFziMY2VX2bdyuF5YzyHhmapT+e21kuTatB50UsXzxlYEWpCmFdnd4LhwFn6AycJWOV0k3e0ePpVxgHc+pVfE89322cbmfuppeHxvxc+KSzQNYC59A+A2vhucbuWppyL3EIF4YgLwOr5iDISm1IR0+EEL3yJQIG4M2WKu526anI85QBcIWyFwQXOpdcX2eZRcd6WW2EgAM3fIOaezkm0CFrsz8rQ0MPYZI4BS2CWwg5d4Bj7SU2sjXz62gfQkQGTYWSqhizVb root@localhost")
	key, detailedResponse, err := vpcService.CreateKey(sshKeyOptions)
	if err != nil {

	}
	log.Printf("SSH key: %s created with ID: %s", *key.Name, *key.ID)

	// Delete SSH key
	detailedResponse, err = vpcService.DeleteKey(&vpcv1.DeleteKeyOptions{
		ID: key.ID,
	})
	if err != nil {
		log.Fatalf("Failed to delete the ssh key: %v and the response is: %s", err, detailedResponse)
	}

	log.Printf("SSH key: %s deleted with ID: %s", *key.Name, *key.ID)
}

Setting up VPC on Classic service

A quick example to get you up and running with VPC on Classic Go SDK service in Dallas (us-south) region.

For other regions, Refer API Endpoints for VPC on Classic and update the URL variable accordingly.

Refer to the VPC on Classic Release Notes document to find out latest version release.
