Hey folks, any idea when support for ec2:DescribeInstanceTypes will land in the v2 sdk ?

@foxroot

when initiating an aws session and I've got MFA enabled on my account with MFA serial number in the credentials file I'm getting an error

panic: failed to load config, token provider required for AssumeRole with MFA

when I disable MFA and remove the MFA serial from the credentials, it works. Does this mean MFA is not currently supported?

Hey folks! Wondering if anyone has experience using aws-sdk-go-v2 to assume a role using web identity tokens? It appears as though it has been enabled here (aws/aws-sdk-go#2667) but not yet in v2 (https://github.com/aws/aws-sdk-go-v2/issues/475). However, I believe it should be possible to do manually with the sts client.

^ follow-up on above, I was able to get this working manually, and hopefully will be able to get it contributed back upstream to make it more seamless for others in the future :)

is anyone from AWS monitoring this chat?

Why were environemnt variable names unexported? aws/aws-sdk-go-v2#508

Ghost

@ghost~5eba03abd73408ce4fe36af4

@gkze I imagine those were unexported so that the values couldn't be tampered with after initialization.

I misread the patch, that is interesting

Question: Is basic functionality for endpoint IoT (MQTT pub/sub) support via aws-sdk-go-v2? Example (https://github.com/aws/aws-iot-device-sdk-python/blob/master/samples/basicPubSub/basicPubSub.py) That example is pretty easy to follow, but I get lost trying to find similar API calls in aws-sdk-go-v2

Hey guys, I've never ever been able to get the conditional expression for the AWS V1 SDK to work with updates. Is this something that people have experienced issues with and is resolved in the v2?

gkhnoisgtht

@gkhnoisgtht

Are you able to pass the secret key and access key instead of loading from the environment? if so is there an example?

for go v2 sdk

rfc2119

@rfc2119

AWS gophers, I have found a non-working example in API v1 for ec2 DescribeSpotPriceHistory. It is not found in v2. Should I PR the v1 API ?

Jasdeep Singh

@jay-dee7

guys do we have way to send a filter while fetching secrets from aws secrets manager? i see v1 has it but v2 doesnt

Ward Vandewege

@cure

@gkhnoisgtht yeah I do something like this:

cfg := defaults.Config()

creds := aws.NewChainProvider(
    []aws.CredentialsProvider{
      aws.NewStaticCredentialsProvider(AccessKey, SecretKey, AuthToken),
      ec2rolecreds.New(ec2metadata.New(cfg)),
    })

cfg.Credentials = creds

svc := s3.New(cfg)

@kaihendry

Since upgrading v2 I'm hitting this error=EC2RoleRequestError: no EC2 instance role found ... not sure why

Kai Hendry

@kaihendry

I created aws/aws-sdk-go-v2#715

rfc2119

@rfc2119

In the example for the NewDescribeInstancesPaginator (and probably all paginators):

p := ec2.NewDescribeInstancesRequestPaginator(req)

should be

p := ec2.NewDescribeInstancesPaginator(req)

It's not critical. Should I open an issue ?

@ianchildress

wow, v0.25.0 and v.0.26.0 are a real pain in the ass. this is going to take days of team effort to fix all the breaking changes. it's not even a single breaking change, there are MANY breaking changes. not happy.

v0.26.0 missing paginator for the s3 apis or am I missing something

Ichinose Shogo

@shogo82148

An issue for paginators is here aws/aws-sdk-go-v2#439 but I don't know its status...

Erik Müller

@asterikx

Hi there, can anyone show me how to create a presigned upload url using v0.26.0 that I can then distribute to web clients to upload images to s3? Previously I had:

req, _ := svc.GetObjectRequest(&s3.GetObjectInput{
    Bucket: aws.String("MY_BUCKET"),
    Key:    aws.String("a-key"),
})
return req.Presign(300*time.Second)

In v0.26.0 the GetObjectRequest has been removed. There is only GetObject but that one does not return a request object ready to be signed. I appreciate any help!

Is there any was to build the whole SDK project (with all dependencies) inside a VM, by not involving containers?

Ichinose Shogo

Are AWS engineers on Gitter?

Ben Waters

@thebenwaters

Anyone have ideas on this?

github.com/aws/aws-sdk-go-v2/aws/endpoints: module github.com/aws/aws-sdk-go-v2@latest found (v0.26.0), but does not contain package github.com/aws/aws-sdk-go-v2/aws/endpoints

Ichinose Shogo

@shogo82148

It seems that it is moved into each service packages. https://github.com/aws/aws-sdk-go-v2/blob/f519313dec379e291a33c4e4309bb99dab4e79f0/service/ec2/endpoints.go#L20-L23

Ben Waters

@thebenwaters

Thanks @shogo82148

Jeff

@jcarter3

so as of v0.26.0, all paginators are gone?

Promaethius

@Promaethius

@thebenwaters do you have a working example on using endpoints?

Jeff

@jcarter3

what version were you using when the endpoints did work?

Promaethius

@Promaethius

I'm used to the v1 sdk where the endpoint resolver is passed as a function in with a general config, trying to migrate

rfc2119

@rfc2119

v0.26.0 breaks a lot of stuff. Since this chat room is not active, anyone know where do gophers using the SDK hang out ?

Jeff

@jcarter3

@rfc2119 yes it does... took a couple days to fix all the errors (though my project is probably not normal)

Alban B

@aboitier_gitlab

@rfc2119 good question

is v.0.29.0 safe to use? i have many middleware dependency issues.

../../../../pkg/mod/github.com/aws/aws-sdk-go-v2/service/sts@v0.29.0/api_op_AssumeRole.go:326:2: undefined: "github.com/aws/aws-sdk-go-v2/aws/middleware".AddRequestInvocationIDMiddleware

Dre

@dre2004

is "github.com/aws/aws-sdk-go-v2/aws/external" broken? I get

ain.go:8:2: module github.com/aws/aws-sdk-go-v2@latest found (v0.29.0), but does not contain package github.com/aws/aws-sdk-go-v2/aws/external

or is the documentation out of date?

Ichinose Shogo

@shogo82148

which documentation?

AWS introduced big breaking changes into v0.25.0. aws/external is renamed to aws/config. https://github.com/aws/aws-sdk-go-v2/blob/master/CHANGELOG.md#relocated-packages

Dre

@dre2004

this documentation https://docs.aws.amazon.com/sdk-for-go/v2/api/aws/external/

I guess a lot of it seems out of date, the config package isn't there

Ichinose Shogo

@shogo82148

yes, it is out of date. it looks that it doesn't contain the changes of v0.25.0. v0.25.0 breaks many and many things...

Hello, I have a question about types.BucketLocationConstraint.
When I call s3.Client.GetBucketLocation and print s3.GetBucketLocationOutput.BucketLocationConstraint, it shows nothing.
Is there any solutions? aws-sdk-go-v2 documentation always says about v1!

Jeff

@jcarter3

@LumpKim i don't believe there is a workaround for this yet, I think it's broken at the generation-via-smithy level

JaeHoon Kim

@LumpKim

Thanks @jcarter3

Not getting this example snippet: aws.EndpointResolverFunc(func(service, region string) (aws.Endpoint, error) {} - service does not have a Type ? https://aws.github.io/aws-sdk-go-v2/docs/configuring-sdk/endpoints/

@This-Is-Not-Brad

I'm having great difficulty getting v4 signing working since the 0.25.0 changes. Doing a basic GET to an IAM authorised Lambda. Are their any updated examples? All the documentation\resources I can find appear to be for <0.25.0

Julio Chana

@jchanam

Hi!
I'm developing some tools with the SDK and I'd like to know if there's documentation in some places about the possible errors that a call could give. I'm using the errors.As to check if the error given is a specific one but sometimes I can't know the kind to expect.
