Spotinst SDK Go
The official Spotinst SDK for the Go programming language.
Table of Contents
Installation
The best way to get started working with the SDK is to use go get to add the SDK to your Go application using Go modules.
go get -u github.com/spotinst/spotinst-sdk-go
Without Go Modules, or in a GOPATH with Go 1.11 or 1.12 use the /... suffix on the go get to retrieve all of the SDK's dependencies.
go get -u github.com/spotinst/spotinst-sdk-go/...
Authentication
Set a ChainProvider
that will search for a provider which returns credentials.
The ChainProvider
provides a way of chaining multiple providers together
which will pick the first available using priority order of the Providers
in the list. If none of the Providers retrieve valid credentials, ChainProvider
's
Retrieve()
will return the error ErrNoValidProvidersFoundInChain
. If a Provider
is found which returns valid credentials ChainProvider
will cache that Provider
for all calls until Retrieve
is called again.
Example of ChainProvider
to be used with an EnvCredentialsProvider
and
FileCredentialsProvider
. In this example EnvProvider
will first check if
any credentials are available via the SPOTINST_TOKEN and SPOTINST_ACCOUNT environment variables. If there are
none ChainProvider
will check the next Provider
in the list, FileProvider
in this case. If FileCredentialsProvider
does not return any credentials
ChainProvider
will return the error ErrNoValidProvidersFoundInChain
.
// Initial credentials loaded from SDK's default credential chain. Such as
// the environment, shared credentials (~/.spotinst/credentials), etc.
sess := session.New()
// Create the chain credentials.
creds := credentials.NewChainCredentials(
new(credentials.FileProvider),
new(credentials.EnvProvider),
)
// Create service client value configured for credentials
// from the chain.
svc := elastigroup.New(sess, &spotinst.Config{Credentials: creds})
Complete SDK Example
package main
import (
"context"
"log"
"github.com/spotinst/spotinst-sdk-go/service/elastigroup"
"github.com/spotinst/spotinst-sdk-go/service/elastigroup/providers/aws"
"github.com/spotinst/spotinst-sdk-go/spotinst"
"github.com/spotinst/spotinst-sdk-go/spotinst/session"
"github.com/spotinst/spotinst-sdk-go/spotinst/util/stringutil"
)
func main() {
// All clients require a Session. The Session provides the client with
// shared configuration such as account and credentials.
// A Session should be shared where possible to take advantage of
// configuration and credential caching. See the session package for
// more information.
sess := session.New()
// Create a new instance of the service's client with a Session.
// Optional spotinst.Config values can also be provided as variadic
// arguments to the New function. This option allows you to provide
// service specific configuration.
svc := elastigroup.New(sess)
// Create a new context.
ctx := context.Background()
// Read group configuration.
out, err := svc.CloudProviderAWS().Read(ctx, &aws.ReadGroupInput{
GroupID: spotinst.String("sig-12345"),
})
if err != nil {
log.Fatalf("spotinst: failed to read group: %v", err)
}
// Output.
if out.Group != nil {
log.Printf("Group %q: %s",
spotinst.StringValue(out.Group.ID),
stringutil.Stringify(out.Group))
}
}
