I found the error, I was using a json with indentation (in the aws it worked). When I put this format without spaces it worked. Maybe it would be interesting to put this note on the page, about how json needs to be formatted. Thank you very much, I was trying to make it work for days.

I tried the aws iam create role on master today and it worked for me. I've used your policy file with "Main" corrected to "Principal", like below:
{
"Version":"2012-10-17",
"Statement":[
{
"Effect":"Allow",
"Principal":{
"AWS":[
"arn:aws:iam:::user/someuser"
]
},
"Action":[
"sts:AssumeRole"
]
}
]
}
Thanks,
Pritha

Hi Pritha, thanks for the answer.
Even changing to Principal I still get the MalformedPolicyDocument. I tested with aws cli versions 1 and 2, both returning the error message. I put JSON in several validators to see if there were any errors and it seems to be okay. I don't know if I'm missing something in the aws cli configuration, my credentials are:
[default]
aws_access_key_id = < admin-api-user key >
aws_secret_access_key = < admin-api-user secret >
And my config:
[default]
region = US
output = json
And I checked that no rule with the same same exists.
With the example python from the page [ https://mail-inspector.serpro.gov.br/mailinspector/tap/WarningUrlPage.php?HSCTYPE=0&HSCRULE=4&HSCID=NDkyNzc5QURCNkUuQTlDNUI=&HSCMLICHECKID0005=b70b7db3446fb5c45272034c5174fcaa&URLCHECKHSCMLI09132012warnning=aHR0cHM6Ly9kb2NzLmNlcGguY29tL2VuL2xhdGVzdC9yYWRvc2d3L1NUUy8= | https://docs.ceph.com/en/latest/radosgw/STS/ ] it worked (it has an extra "]" that needs to be removed in the policy_document variable).
Thanks again, Marcelo.

Hi Marcelo,
Your trust policy has an error:
{
"Version":"2012-10-17",
"Statement":[
{
"Effect":"Allow",
" Main ":{
"AWS":[
"arn:aws:iam:::user/someuser"
]
},
"Action":[
"sts:AssumeRole"
]
}
]
}
In place of 'Main', use 'Principal' as you have done for the radosgw-admin role create command.
Thanks,
Pritha

Hello all!
I'm having a hard time trying to get the STS to work. I want to give a user "someuser" the ability to assumerole. I don't know if I got it wrong how to do it, or if my json is spelled wrong.
I've done tests on the latest versions of nautilus, octopus and pacific, and I always get the same message.
In RGW I added the following settings:
---------------------
rgw_s3_auth_use_sts = true
rgw_sts_key = "abcdefghijklmnop"
---------------------
Then I create a user "admin-api-user", giving the following caps:
---------------------
# radosgw-admin caps add --uid admin-api-user --caps "users=*;buckets=*;metadata=*;usage=*;roles=*;user-policy=*"
---------------------
But when I try to create a role using aws cli, I get an error message:
---------------------
# aws --endpoint= [ [ https://mail-inspector.serpro.gov.br/mailinspector/tap/WarningUrlPage.php?HSCTYPE=0&HSCRULE=4&HSCID=OTM1Q0I0OEYwODkuQTc4N0Q=&HSCMLICHECKID0005=b70b7db3446fb5c45272034c5174fcaa&URLCHECKHSCMLI09132012warnning=aHR0cDovLzEwLjc5LjM1LjI0NTo3NDgw | https://mail-inspector.serpro.gov.br/mailinspector/tap/WarningUrlPage.php?HSCTYPE=0&HSCRULE=4&HSCID=OTM1Q0I0OEYwODkuQTc4N0Q=&HSCMLICHECKID0005=b70b7db3446fb5c45272034c5174fcaa&URLCHECKHSCMLI09132012warnning=aHR0cDovLzEwLjc5LjM1LjI0NTo3NDgw ] | [ https://mail-inspector.serpro.gov.br/mailinspector/tap/WarningUrlPage.php?HSCTYPE=0&HSCRULE=4&HSCID=NDkyNzc5QURCNkUuQTlDNUI=&HSCMLICHECKID0005=b70b7db3446fb5c45272034c5174fcaa&URLCHECKHSCMLI09132012warnning=aHR0cDovLzEwLjc5LjM1LjI0NTo3NDgw | http://10.79.35.245:7480 ] ] iam create-role --role-name=role1 --assume-role-policy-document file://policy_document.json
An error occurred (Unknown) when calling the CreateRole operation: Unknown
---------------------
Running the above command with debug, on one of the lines comes the following message:
---------------------
2021-09-02 10:07:56,138 - MainThread - botocore.parsers - DEBUG - Response body:
b'<?xml version="1.0" encoding="UTF-8"?><Error><Code>MalformedPolicyDocument</Code><RequestId>tx000000000000000001-006130ccac-b3b82-default</RequestId><HostId>b3b82-default -default</HostId></Error>'
---------------------
My policy_document.json is like this:
---------------------
{
"Version":"2012-10-17",
"Statement":[
{
"Effect":"Allow",
"Main":{
"AWS":[
"arn:aws:iam:::user/someuser"
]
},
"Action":[
"sts:AssumeRole"
]
}
]
}
---------------------
If I run the the radosgw-admin command with the same JSON (but with escaped characters), it works:
---------------------
# radosgw-admin role create --role-name=role1 --assume-role-policy-doc=\{\"Version\":\"2012-10-17\",\"Statement\":\[\{\"Effect\":\"Allow\",\"Principal\":\{\"AWS\":\[\"arn:aws:iam:::user/someuser\"\]\},\"Action\":\[\"sts:AssumeRole\"\]\}\]\}
{
"RoleId": "007ed38e-a072-43a4-94f3-2958e5a19408",
"RoleName": "role1",
"Path": "/",
"Arn": "arn:aws:iam:::role/role1",
"CreateDate": "2021-09-02T13:19:39.721Z",
"MaxSessionDuration": 3600,
"AssumeRolePolicyDocument": "{\"Version\":\"2012-10-17\",\"Statement\":[{\"Effect\":\"Allow\",\"Principal\":{\"AWS\":[\"arn:aws:iam:::user/someuser\"]},\"Action\":[\"sts:AssumeRole\"]}]}"
}
---------------------
Does anyone have any idea where I might be going wrong? I did a test on aws, with the same JSON (adding my arn account) and it worked.
Thanks, Marcelo!
