Assume Role with Minio-js

[ryansteakley]

I have seen #960 however there is no documentation on how to really use this feature that I can find?

How does a user use something like AWS assume role and create a minioclient? This goes in hand with the previous issue #841 where in the minio-go side they get the webidentitytoken etc... On minio-js side it is not clear how the js code gets this information when creating the client.

The current example

var Minio = require('minio')

var s3Client = new Minio.Client({
    endPoint:  's3.amazonaws.com',
    accessKey: 'YOUR-TEMP-ACCESSKEYID',
    secretKey: 'YOUR-TEMP-SECRETACCESSKEY',
    sessionToken: 'YOUR-TEMP-SESSIONTOKEN'
})

doesn't seem to explain how to provide the fields that were implemeneted in #960 i.e credentialsProvider

Is there documentation or any example of IAM for Service Account in minio-js?

You could use example from

minio-js/src/test/functional/functional-tests.js

Line 40 in 4fce54b

let AssumeRoleProvider

Example is also provided in the PR. We will update an example soon.

Please follow the steps https://github.com/minio/minio/blob/master/docs/sts/assume-role.md

From examples since none seem to use webIdentityToken it is not clear what needs to be done here?
Do I need to pass the webIdentityToken and the roleARN into

let asRoleProvider = new AssumeRoleProvider({
    stsEndpoint: "s3.amazonaws.com",
    accessKey: 'miniojs',
    secretKey: 'miniojs123',
    webIdentityToken: '/var/secret/etc/',
    roleARN: "arn:aws:...."
})

For it work or will these be picked up automatically when using this AssumeRoleProvider?
