Net Core 2.0 AmazonServiceException: Unable to find credentials

Question

I have the following code:

public void ConfigureServices(IServiceCollection services)
{
    // AWS Options
    var awsOptions = Configuration.GetAWSOptions();
           


        

Answer 1

So when we are using AWS SDK we need to setup and provide an AWS access key & a secret key. And from what I have come across it does not read directly from the app settings. So I found below are the two working methods with which you can set these credentials.

Method 1 - Using Credentials file

You can create a credentials file and store your credentials there. Below is the format of the file.

[default]
aws_access_key_id = your id goes here
aws_secret_access_key = your password goes here

In above file, "default" is the name of your profile.

After creating the above file you need to specify the same in Appsettings.json file as:

"AWS": {
    "Profile": "default",
    "ProfilesLocation": "C:\\filelocation\\awscredentials",
    "Region": "us-east-1",
   }

Method 2 - Setting and Reading from Environment Variables

We can setup the environment variables in our startup.cs file as below:

Environment.SetEnvironmentVariable("AWS_ACCESS_KEY_ID", Configuration["AWS:AwsId"]);
Environment.SetEnvironmentVariable("AWS_SECRET_ACCESS_KEY", Configuration["AWS:AwsPassword"]);
Environment.SetEnvironmentVariable("AWS_REGION", Configuration["AWS:Region"]); 

And read these variables from our appSettings.json file as:

AWS": {
        "Region": "us-east-1",
        "AwsId": "xxxx",
        "AwsPassword": "xxxx"
      }
