List Queues in AWS SQS using Go
development golang aws sqs- Create Queues in AWS SQS using Go
- List Queues in AWS SQS using Go
- Delete Queues in AWS SQS using Go
- Send Messages to AWS SQS using Go
- Receive Messages from AWS SQS using Go
In order to work with AWS SQS using Go, we will use github.com/aws/aws-sdk-go-v2
. In this gist, we will use the aws-sdk-go-v2 package to list queues in AWS SQS. The complete source code for the snippet is available here https://github.com/abvarun226/blog-source-code/tree/master/list-queues-in-aws-sqs-using-go
In order to test the snippet, we will use localstack to run SQS emulator in a docker container on the laptop. The container exposes SQS endpoint on port 4566
. The snippet will then list all queues in the AWS SQS account.
In order to start the localstack
container, you will need to first install localstack:
$ pip install localstack
Localstack provides a fully functional local AWS cloud stack. It is a cloud service emulator that runs in a single container on a laptop or a development machine.
In order to start the AWS services, run:
$ localstack start -d
You can check the status of the services by running:
$ localstack status services
package main
import (
"context"
"log"
"github.com/aws/aws-sdk-go-v2/aws"
"github.com/aws/aws-sdk-go-v2/config"
"github.com/aws/aws-sdk-go-v2/service/sqs"
)
type SQSQueueAPI interface {
ListQueues(ctx context.Context,
params *sqs.ListQueuesInput,
optFns ...func(*sqs.Options)) (*sqs.ListQueuesOutput, error)
}
func ListQueues(c context.Context, api SQSQueueAPI, input *sqs.ListQueuesInput) (*sqs.ListQueuesOutput, error) {
return api.ListQueues(c, input)
}
// creates an sqs client.
func client(ctx context.Context, awsURL, region string) *sqs.Client {
// customResolver is required here since we use localstack and need to point the aws url to localhost.
customResolver := aws.EndpointResolverWithOptionsFunc(func(service, region string, options ...interface{}) (aws.Endpoint, error) {
return aws.Endpoint{
PartitionID: "aws",
URL: awsURL,
SigningRegion: region,
}, nil
})
// load the default aws config along with custom resolver.
cfg, err := config.LoadDefaultConfig(ctx, config.WithEndpointResolverWithOptions(customResolver))
if err != nil {
log.Fatalf("configuration error: %v", err)
}
return sqs.NewFromConfig(cfg)
}
// list all queues in AWS SQS account.
func listQueues(ctx context.Context, c *sqs.Client) {
inputList := &sqs.ListQueuesInput{}
resultList, err := ListQueues(ctx, c, inputList)
if err != nil {
log.Printf("error retrieving queue URLs: %v", err)
return
}
for i, url := range resultList.QueueUrls {
log.Printf("%d: %s", i+1, url)
}
}
func main() {
ctx := context.TODO()
awsURL := "http://127.0.0.1:4566"
awsRegion := "us-west-2"
// create aws client.
c := client(ctx, awsURL, awsRegion)
// list all queues in the SQS account.
listQueues(ctx, c)
}
Output:
➜ export AWS_SECRET_ACCESS_KEY=foobar
➜ export AWS_ACCESS_KEY_ID=foobar
➜ go run main.go
