AWS Elasticsearch Service - 手動快照到 S3

Question

我嘗試創建我的“Amazon Elasticsearch Service”的手動快照我找到了這個文檔，但是我在最后一步“注冊快照存儲庫”中遇到了問題。 我搜索了 .net 的解決方案，但此示例是一個 python 腳本，我找不到 .net 的解決方案

是否有可用於簽署 c# 請求的解決方案？

phyton 腳本來簽署請求

from boto.connection import AWSAuthConnection

class ESConnection(AWSAuthConnection):

    def __init__(self, region, **kwargs):
        super(ESConnection, self).__init__(**kwargs)
        self._set_auth_region_name(region)
        self._set_auth_service_name("es")

    def _required_auth_capability(self):
        return ['hmac-v4']

if __name__ == "__main__":

    client = ESConnection(
            region='eu-west-1',
            host='search-domain.eu-west-1.es.amazonaws.com',
            profile_name='ifOtherThanDefault',
            is_secure=False)

    print 'Registering Snapshot Repository'
    resp = client.make_request(method='PUT',
            path='/_snapshot/es-index-backups',
            data='{"type": "s3","settings": { "bucket": "my-es-snapshot-repo","region": "eu-west-1","role_arn": "arn:aws:iam::123456789012:role/es-snapshots-role"}}')
    body = resp.read()
    print body

C#解決方案

var createPolicyJson = @"{

亞馬遜請求 (AWSSDK.IdentityManagement)

//Change the bucket to the correct bucket
var s3BucketName = "test.elasticsearch";
createPolicyJson = createPolicyJson.Replace("my-es-snapshot-repo", s3BucketName);


var awsCredentials = new BasicAWSCredentials("accessKey", "secretKey");
var client = new AmazonIdentityManagementServiceClient(awsCredentials, Amazon.RegionEndpoint.EUCentral1);

var createRoleRequest = new CreateRoleRequest
{
    RoleName = "ElasticsearchSnapshotsRole",
    AssumeRolePolicyDocument = createRoleJson
};

var createPolicyRequest = new CreatePolicyRequest
{
    PolicyName = "ElasticsearchSnapshotAccess",
    PolicyDocument = createPolicyJson
};

var responseCreateRole = client.CreateRole(createRoleRequest);
var responseCreatePolicy = client.CreatePolicy(createPolicyRequest);
var responseAttachRolePolicy = client.AttachRolePolicy(new AttachRolePolicyRequest { PolicyArn = responseCreatePolicy.Policy.Arn, RoleName = responseCreateRole.Role.RoleName });
