S3 Presigned URL microservice prototype written in Go. Using AWS SDK in Go.
Returns the presigned URL for downalod with 15 mins expiration. Service listen to 8082 (changeable)
Effectively returns same as “aws s3 presign bucket_name/key --expires-in 60*15”
go run main.go
or: go build main.go
./main &
curl "http://localhost:8082/presign?s3path={s3path}
{s3path} as “bucket_name/key” (see ‘/‘ delimiter)
Example:
localhost:8082/presign?s3path=ejoliet-dummy/hello.html
Go to S3 bucket, select the file to get the URL presigned, copy URI, remove the 's3://' part, then go here to encode it:
example:
roman-airflow-demo/airflow-dev/logs/dag_id=01_hello_world/run_id=manual__2023-05-18T01:08:39.382762+00:00/task_id=hello_world_bash_operator/attempt=1.log
becomes
roman-airflow-demo%2Fairflow-dev%2Flogs%2Fdag_id%3D01_hello_world%2Frun_id%3Dmanual__2023-05-18T01%3A08%3A39.382762%2B00%3A00%2Ftask_id%3Dhello_world_bash_operator%2Fattempt%3D1.log
Use this for the value of s3path.
