how can i get the true tiken
Cristian M.S.

did anyone try to parse the pricing API data in into a native Go object? I'm having a hard time with this

{"product":{"productFamily":"Storage","attributes":{"storageMedia":"SSD-backed","maxThroughputvolume":"1000 MiB/s","volumeType":"Provisioned IOPS","maxIopsvolume":"64000","servicecode":"AmazonEC2","usagetype":"EBS:VolumeUsage.io2","locationType":"AWS Region","volumeApiName":"io2","location":"US East (N. Virginia)","servicename":"Amazon Elastic Compute Cloud","maxVolumeSize":"16 TiB","operation":""},"sku":"6V576P37PS7K7KYU"},"serviceCode":"AmazonEC2","terms":{"OnDemand":{"6V576P37PS7K7KYU.JRTCKXETXF":{"priceDimensions":{"6V576P37PS7K7KYU.JRTCKXETXF.6YS6EN2CT7":{"unit":"GB-month","endRange":"Inf","description":"$0.125 per GB-month of Provisioned IOPS SSD (io2)  provisioned storage - US East (Northern Virginia)","appliesTo":[],"rateCode":"6V576P37PS7K7KYU.JRTCKXETXF.6YS6EN2CT7","beginRange":"0","pricePerUnit":{"USD":"0.1250000000"}}},"sku":"6V576P37PS7K7KYU","effectiveDate":"2021-07-01T00:00:00Z","offerTermCode":"JRTCKXETXF","termAttributes":{}}}},"version":"20210709001917","publicationDate":"2021-07-09T00:19:17Z"}

any clues how to handle the OnDemand and PriceDimensions structs?

I ended up doing some regex replaces on those SKU values before unmarshaling, this is so fugly

I finally got some code able to parse the EBS pricing and expose it in a more user-friendly format, if anyone is interested in this please let me know, I will eventually open source it but I can share it earlier upon demand

I'm looking for a way to set the signature version explicitly for a client. found documentation for various SDKs, but not for golang

I am trying to use AWS SDK for Go to implement S3 apis to connect with third party storage provider (Dell OneFS) who support S3 API. First in place, is AWS SDK is tightly coupled with AWS or it can be used to connect with any storage provider who support S3 API? If so, can someone help me to configuring the target host and other details?


Yuval Lifshitz
you can connect to any storage that supports S3. e.g. i use it to connect to object storage gateway of Ceph (https://ceph.io/en/)
I use the NewSession() call from: github.com/aws/aws-sdk-go/aws/session
you pass it a NewConfig() with endpoint, credentials, region, and all other parameters pointing to your storage provider
Thank you Yuval, for the response on this. Let me check and confirm on this.
Yuval, it's working... great thanks for your help on this... it is really appreciated...
Hi yuvalif, when I am uploading document bucket name is appended to the Put request. Getting error "RequestError: send request failed
caused by: Put "http://bucketname.hostname.com:9020/uploaddoc.pdf": dial tcp: lookup bucketname.hostname.com: no such host"
Did you face such problem? how to avoid appending bucketname in the url? or is there any other work around?
Yuval Lifshitz
yes , had this problem :-)
use: WithS3ForcePathStyle(true) in the config, so that the bucket name would appear in the "path" and not the "host"
@yuvalif you are the saviour :) it worked. I am not getting what they are coming to say when I am reading aws documentation for this method. I felt the documentation is not clear... Thanks a lot for the help on this...
@yuvalif , I am setting some user defined metadata while uploading a file. How to retrieve these metadata using Go SDK?

@JK sorry, don't know about that

Can someone help me with documentation on guidelines for retrying s3 upload on error?

Hello all. Sad to see this channel seemingly be a bit dead. I was hoping if someone on the AWS SDK team could answer this stackoverflow that I posted 20 days ago: https://stackoverflow.com/questions/69692732/how-to-call-the-values-function-in-aws-sdk-go-v2
Since stackoverflow is suggested in the SDK readme, I was hoping that some people from AWS would be monitoring it, but it seems like this is not the case either. I am trying to avoid opening a github issue.
2 new tools built using aws-sdk-go and made opensource :-
Please have a look and let me know your thoughts!! Any feedback/suggestions are highly appreciated

Hi there!
I've just started using Lambda and Go thus sorry for newbie questions.

So the question:
I have a lambda that may return errors with different status codes: 400, 404, 500.
On top of it I have an API Gateway that right now always returns me 502 when lambda returns any error.
I've failed to map it through response templates.

Could someone please give me a hand with this? What is a proper way to manage errors handling?

I want to know, 1. which version is stable about aws-go-sdk for Neptune? 2. where is the code example for Go SDK about Neptune?

Any Idea?
how to enable aws-sdk-go debugging in go program ? for example I want to see all communication between client and server like http headers in xml format to a file .
Is it possible to use the same client to get multiple services, such as ec2, s3 and rds, I don't want to create 3 kinds of clients.
is the aws-sdk-go crypto library FIPS compliant ? I think it uses go crypto library which is not FIPS compliant . Is there any easy way to make client using the aws-sdk-go FIPS compliant ?
Can anyone here help me with connecting to AWS IoT Core via MQTT over Websocket?

Hey everyone. I've hit an issue that I don't understand. I have a piece of Go code that calls a Lambda to modify a user's IAM policy, enabling them to assume a role in a different account. The Go code then tries to wait for up to 3 minutes until it can assume that role. However, this never succeeds until the whole application is restarted, where the assume role call works immediately. I've tried creating new sessions for every attempt and using an STS client from that new session, but it seems to suggest that something somewhere is caching the content of that IAM policy for the duration of the Go code execution. I have read through the SDK source code and I can't see something that would do that, but maybe I'm missing some nuance somewhere. The code is executing in the context of being run from a shell created by aws-vault. Any ideas? It's driving me mad.
