How to set credentials on AWS SDK on NET Core?

Question

I'm new to AWS SDK and I'm trying to follow the AWS documentation, but gives little to none on what exactly I need to setup.

The official docs tell me to add this to the appsettings.json:

{   "AWS": {     "Profile": "local-test-profile",     "Region": "us-west-2"   } } 

And then create the client:

var options = Configuration.GetAWSOptions(); IAmazonS3 client = options.CreateServiceClient<IAmazonS3>(); 

This causes an exception to be thrown saying it cannot find the credentials. Where do I put the Api ID and Key? What is this profile?

Please, bear in mind I have no preferences on how to set this up. I'm just trying to follow the official documentation for .NET Core, and their only example doesn't work. The docs seem to imply I should have prior knowledge of many of their terms and settings or that I'm migrating an existing app and already have everything setup.

Can someone please point me to what is missing from this example just to make the API correctly connect to AWS?

Maybe this is too late for you but if you are using docker or have some other environment/setup where it's not possible/easy to use AWS profiles then you can still use environment vars. Eg:

var awsOptions = Configuration.GetAWSOptions(); awsOptions.Credentials = new EnvironmentVariablesAWSCredentials(); services.AddDefaultAWSOptions(awsOptions); services.AddAWSService<IAmazonS3>(); 

Then set AWS_ACCESS_KEY_ID & AWS_SECRET_ACCESS_KEY & AWS_REGION in your environment.

It seems that Amazon have made this harder to find in the docs than it needs to be.

Running in AWS for reals is ok because you should be using a role but if your using docker for dev then setting up a profile in the container is a PITA.
