--iam-instance-profile not being parsed correctly

[utterlyforked]

I know this issue has been raised previously in a few similar issues (#1470 and #2392) but I'm still seeing a simliar behaviour in a very recent release

Andrews-MacBook:~ andrewtaylor$ aws --version
aws-cli/1.11.97 Python/2.7.10 Darwin/16.6.0 botocore/1.5.60

--iam-instance-profile parameter causes error

Andrews-MacBook:~ andrewtaylor$ aws ec2 run-instances --image-id ami-01ccc867 --key-name systemmanager --instance-type m3.medium --iam-instance-profile systemmanager-instancerole

Error parsing parameter '--iam-instance-profile': Expected: '=', received: 'EOF' for input:
systemmanager-instancerole

I tried with the same parameter but removing the hyphen from the argument value in case it was just the value being passed. Same result:

Andrews-MacBook:~ andrewtaylor$ aws ec2 run-instances --image-id ami-01ccc867 --key-name systemmanager --instance-type m3.medium --iam-instance-profile systemmanager

Error parsing parameter '--iam-instance-profile': Expected: '=', received: 'EOF' for input:
systemmanager

When I remove the --iam-instance-profile argument the command is successful.

Here's the debug output which looks as if the params are correct.

Andrews-MacBook:~ andrewtaylor$ aws ec2 run-instances --image-id ami-01ccc867 --key-name systemmanager --instance-type m3.medium --iam-instance-profile systemmanager --debug 2>&1 | grep "Arguments entered"
2017-06-06 09:42:17,498 - MainThread - awscli.clidriver - DEBUG - Arguments entered to CLI: ['ec2', 'run-instances', '--image-id', 'ami-01ccc867', '--key-name', 'systemmanager', '--instance-type', 'm3.medium', '--iam-instance-profile', 'systemmanager', '--debug']

Is this a regression?

You need to specify whether you're providing a name or an arn (or both), like so: Name=systemmanager-instancerole. There are examples in the docs which demonstrate this.

Oh well now I feel foolish!

Thanks for the heads-up. Perhaps a pull request for a change in the error message would be accepted?

The original issue was resolved and documentation shows expected parameter. Since the error returned notes which parameter is at fault, we wouldn't try to parse this particular specification as incorrect.

Its been 4 years and i literally ran into the same issue, its almost like were all treading down the same path, running into the same mistakes.

This stuff is not documented. This is how the the parameter needs to be passed:
# aws ec2 associate-iam-instance-profile --iam-instance-profile '{"Name": "name of the profile" }'
OR
# aws ec2 associate-iam-instance-profile --iam-instance-profile '{"arn": "arn of the profile" }'
OR
`# aws ec2 associate-iam-instance-profile --iam-instance-profile Name=name of the profile
