envassume
Assume an AWS IAM role and execute a command with the assumed credentials. AWS API credentials to assume the role must be set as environment variables, and the command and arguments are executed in the same manner as envdir.
envassume takes the effort out of assuming an AWS role from the command-line and copying/pasting the returned credentials to run a command. If you often need to do this:-
$ aws sts assume-role --role-arn arn:aws:iam::123456789012:role/s3_access --role-session-name s3_access_session
{
"AssumedRoleUser": {
"AssumedRoleId": "xxxxxxxxxxxxxxxxxxxxx:s3_access_session",
"Arn": "arn:aws:sts::123456789012:assumed-role/s3_access/s3_access_session"
},
"Credentials": {
"SecretAccessKey": "mmm",
"SessionToken": "nnn",
"Expiration": "2019-02-26T00:00:00Z",
"AccessKeyId": "ooo"
}
}
$ AWS_ACCESS_KEY_ID='ooo' AWS_SECRET_ACCESS_KEY='mmm' AWS_SESSION_TOKEN='nnn' aws s3 ls
It can be shortened to:-
$ envassume arn:aws:iam::123456789012:role/s3_access aws s3 ls
Useful if you often need to test roles, or run scripts with assumed roles on AWS instances using credentials from the instance profile.
