由于身份验证，gsutil无法复制到s3 [英] gsutil cannot copy to s3 due to authentication

问题描述

我需要将许多(1000+)个文件从GCS复制到s3，以利用AWS lambda函数.我已经编辑了~/.boto.cfg并注释掉了2个aws身份验证参数，但是一个简单的gsutil ls s3://mybucket在 GCE 或 EC2 VM中失败.

错误为The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256..

我使用的是gsutil版本:4.28， GCS 和 S3 存储桶的位置分别是US-CENTRAL1和US East (Ohio)-如果需要的话.

我一无所知，因为AWS密钥是有效的，并且启用了http/https.使用笔记本电脑的Cyber​​duck从GCS下载并上传到S3是不可行的(> 230Gb)

解决方案

根据 https://issuetracker. google.com/issues/62161892 ，gsutil v4.28 确实支持AWS v4签名，方法是在~/.boto中添加新的[s3]部分，例如

[s3]
# Note that we specify region as part of the host, as mentioned in the AWS docs:
# http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region
host = s3.eu-east-2.amazonaws.com
use-sigv4 = True

该部分的使用是从boto3继承的，但是当前不是由gsutil config创建的，因此需要为目标端点显式添加它.

对于s3-to-GCS，我将考虑使用更少服务器的Storage Transfer Service API.

I need to copy many (1000+) files to s3 from GCS to leverage an AWS lambda function. I have edited ~/.boto.cfg and commented out the 2 aws authentication parameters but a simple gsutil ls s3://mybucket fails from either an GCE or EC2 VM.

Error is The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256..

I use gsutil version: 4.28 and locations of GCS and S3 bucket are respectively US-CENTRAL1 and US East (Ohio) - in case this is relevant.

I am clueless as the AWS key is valid and I enabled http/https. Downloading from GCS and uploading to S3 using my laptop's Cyberduck is impracticable (>230Gb)

解决方案

As per https://issuetracker.google.com/issues/62161892, gsutil v4.28 does support AWS v4 signatures by adding to ~/.boto a new [s3] section like

[s3]
# Note that we specify region as part of the host, as mentioned in the AWS docs:
# http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region
host = s3.eu-east-2.amazonaws.com
use-sigv4 = True

The use of that section is inherited from boto3 but is currently not created by gsutil config so it needs to be added explicitly for the target endpoint.

For s3-to-GCS, I will consider the more server-less Storage Transfer Service API.
