S3 kovasına yeni bir nesne konduğunda bir Lambda fonksiyonunu tetiklemek istiyorsanız aşağıdaki komutları kullanın.


Kurulum


// Create lambda function

GOOS=linux CGO_ENABLED=0 go build -ldflags "-s -w" -o lambda/plain/main lambda/plain/main.go

zip lambda.zip lambda/plain/main

aws --profile localstack --endpoint-url http://localhost:4566 lambda create-function \
--function-name test-lambda \
--handler lambda/plain/main \
--runtime go1.x \
--role test-role \
--zip-file fileb://lambda.zip

// Create S3 bucket
aws --profile localstack --endpoint-url http://localhost:4566 s3 mb s3://test-bucket

// Configure S3 and Lambda notification
aws --profile localstack --endpoint-url http://localhost:4566 s3api put-bucket-notification-configuration \
--bucket test-bucket \
--notification-configuration '{"LambdaFunctionConfigurations":[{"Id":"1","LambdaFunctionArn":"arn:aws:lambda:eu-west-1:000000000000:function:test-lambda","Events":["s3:ObjectCreated:Put"]}]}'

Test


aws --profile localstack --endpoint-url http://localhost:4566 s3 cp test.txt s3://test-bucket

Lambda etkinliğiniz böyle görünür.
