Support multiple profiles for AWS about aws-es-proxy HOT 6 OPEN

@leptitchriss I only use it once in a while in limited sessions, never had them expire.

Check out #1

I wasn't able to make it work OOTB either. It probably supports simple profiles, but it doesn't seem to support Assume Roles embedded into profiles. You gotta do the assume role yourself and then output the environment variables for aws-es-proxy to use.

Here's the script I used, hope it can be useful to someone else:

import boto3
from subprocess import run, PIPE

sts = boto3.Session(profile_name='profile_name').client('sts')
creds = sts.assume_role(RoleSessionName='anything_goes',
                        RoleArn='arn:aws:iam::ACCOUNTID:role/ROLE_TO_ASSUME',
                        DurationSeconds=4*60*60)['Credentials']

proxy_args = ['./aws-es-proxy',
              '-endpoint', 'https://my-aws-es-cluster.region.es.amazonaws.com',
              '-verbose',
              '-pretty']

proxy_enviroment = {
    'AWS_ACCESS_KEY_ID': creds['AccessKeyId'],
    'AWS_SECRET_ACCESS_KEY': creds['SecretAccessKey'],
    'AWS_SESSION_TOKEN': creds['SessionToken']
}

proxy = run(proxy_args, env=proxy_enviroment, stdout=PIPE)

Hi,

The ask for a '-profile' option has been raised multiple times. I see that most of the requests come when assume role is being used. I will work on this in the coming days and find a way to better support assuming roles and using different profiles.

Thanks,

from aws-es-proxy.

If it can help, here a snippet from one of my tool for AWS :

	// Arguments
	region := flag.String("region", "eu-west-1", "AWS region")
	profile := flag.String("profile", "default", "Profile from ~/.aws/config")
	flag.Parse()

	// Create session (credentials from ~/.aws/config)
	sess := session.Must(session.NewSessionWithOptions(session.Options{
		SharedConfigState:       session.SharedConfigEnable,  //enable use of ~/.aws/config
		AssumeRoleTokenProvider: stscreds.StdinTokenProvider, //ask for MFA if needed
		Profile:                 string(*profile),
		Config:                  aws.Config{Region: aws.String(*region)},
	}))

@jonapich I know your post is over a year old and the project has been updated since, but I'm running into a very similar problem as you dealing with Assumed Roles and have implemented a very similar solution. What happens to your process once the session token expires? I'm considering going with this approach and simply refreshing the session credentials and restarting the proxy each time but it does not seem as elegant as I would have liked.

@abutaha on a side note, the proxy credentials don't seem to pick up the AWS_SESSION_TOKEN in the ~/.aws/credentials file for the default profile. Is that something that can be added? This way we would be able to simply update the temporary credentials provided by the Assume Role call (via aws cli, boto3, or other) and the proxy would simply update itself with the new credentials without having to worry about updating environment variables for a running process.

Aside from that, thank you for your hard work, this project solves a very niche problem that I'm surprised AWS hasn't tackled themselves...

Let me know what you think!
