Community Go Client for STACKIT

The client is community-supported and not an official STACKIT release, it is maintained by internal Schwarz IT teams integrating with STACKIT

Install

To install the latest stable release, run:

go get github.com/SchwarzIT/community-stackit-go-client@latest

Usage Example

In order to use the client, a STACKIT Service Account must be created and have relevant roles assigned to it.
For further assistance, please contact STACKIT support

package main

import (
	"context"
	"fmt"
	"os"

	client "github.com/SchwarzIT/community-stackit-go-client"
	"github.com/SchwarzIT/community-stackit-go-client/pkg/validate"
)

func main() {
	ctx := context.Background()
	c, err := client.New(ctx, client.Config{
		ServiceAccountEmail: os.Getenv("STACKIT_SERVICE_ACCOUNT_EMAIL"),
		ServiceAccountToken: os.Getenv("STACKIT_SERVICE_ACCOUNT_TOKEN"),
	})
	if err != nil {
		panic(err)
	}

	res, err := c.ElasticSearch.Offerings.GetWithResponse(ctx, "{project-id}")
	if aggregatedError := validate.Response(res, err, "JSON200"); aggregatedError != nil {
		panic(aggregatedError)
	}

	fmt.Println("Received the following offerings:")
	for _, o := range res.JSON200.Offerings {
		fmt.Printf("- %s\n", o.Name)
	}
}

Further Examples

1. Under /examples directory
2. In our terraform-provider-stackit

Working with API environments

In order to modify the API environment, set the Environment field to one of dev, qa or prod

• The Environment field is optional
• By default prod is being used

c, err := client.New(ctx, client.Config{
	// ...
	Environment: "qa"
})
