Hello I need some help in determining aws region inside a glue job.
I am trying to use boto3 client kms and when I do the following I get a Error
NoRegionError: You must specify a region.
kms = boto3.client('kms')
Obviously it is asking me to set region_name when creating the client but I do not wish to hardcode the region
When running a glue job i do see a line in the logs which says Detected region us-east-2 but I am not sure on how I can fetch that value ?
回答1:
If you're running Pyspark / Python shell Glue job, try this:
import requests
r = requests.get("http://169.254.169.254/latest/dynamic/instance-identity/document")
response_json = r.json()
region = response_json.get('region')
print region

AWS Glue is still not available in all the regions. You may refer this link
That's the reason you need to hardcode the region.
Coming to the "Detected region us-east-2" this might be becus of your aws CLI configuration
