If you ever get this error when trying to configure the AWS CLI:

Partial credentials found in assume-role, missing: source_profile or credential_source

you need to add one of the those values to the configuration.

One option is to add a role to your EC2 instance that has permissions you need and then use credential_source. Add this to your AWS CLI profile:

credential_source = Ec2InstanceMetadata

The other option is use aws configure to add developer credentials (AWS secret key and access key) to a profile or your default profile and then reference the profile that as your credentials.

In other words:

• Create and obtain your developer credentials.
• Run aws configure and enter the credentails either for the default profile:

aws configure

• Or you can add the credentials to a specific profile which I have name my_profile below:

aws configure --profile my_profile

• Then update whatever other profile for which you are getting the error with either the default profile:

source_profile=default

Or the named profile you created:

source_profile=my_profile

If using Linux, you can view the configuration using this command:

vi ~/.aws/config

And edit the configuration file directly, but if you make a mistake you might have problems.

Another option to add the values would be using aws set:
