NoCredentialProviders: no valid providers in chain when adding a certain aws profile #4989

HenryXie1 · 2023-09-14T21:52:02Z

Describe the bug

We have blow code to describe eks cluster

sess, err := session.NewSessionWithOptions(session.Options{
		Config:            aws.Config{Region: aws.String("ap-southeast-2"), CredentialsChainVerboseErrors: aws.Bool(true)},
		SharedConfigFiles: []string{awsConfigPath},
		SharedConfigState: session.SharedConfigEnable,
		Profile:           clusterName,
	})
	if err != nil {
		fmt.Println("clustername: " + clusterName)
		return err
	}

	fmt.Println("new cluster session good: " + clusterName)
	eksClient := eks.New(sess)
	cluster, err := eksClient.DescribeCluster(&eks.DescribeClusterInput{Name: &clusterName})

	if err != nil {
		return err
	}

it works well before.
after we add below line in the ./aws/config , it starts error out

[profile e02-admin]
sso_start_url = ******
role_arn = arn:aws:iam::******:role/AdministratorRole
source_profile = e02
sso_role_name = PlatformAdmin
region = ap-southeast-2

The error is

new cluster session good: e02
 NoCredentialProviders: no valid providers in chain
caused by: EnvAccessKeyNotFound: failed to find credentials in the environment.
SharedCredsLoad: failed to load profile, e02.
EC2RoleRequestError: no EC2 instance role found
caused by: RequestError: send request failed
caused by: Get "[http://169.254.169.254/latest/meta-data/iam/security-credentials/ ](http://169.254.169.254/latest/meta-data/iam/security-credentials/)": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

Expected Behavior

it was working well before we add e02-admin profile.

Current Behavior

it error out after we add this profile in the .aws/config

[profile e02-admin]
sso_start_url = ******
role_arn = arn:aws:iam::******:role/AdministratorRole
source_profile = e02
sso_role_name = PlatformAdmin
region = ap-southeast-2

profile e02 exists before this issue happens

[profile e02]
sso_start_url = ***
sso_region = ap-southeast-2
sso_account_id = ***
sso_role_name = PlatformAdmin
region = ap-southeast-2

Reproduction Steps

Add e02-admin profile in .aws/config
then the issue is reproduced

Possible Solution

change source_profile in e02-admin from e02 to others (ie d02)
or
remove e02-admin from .aws/config
the issue is gone

the aws cli is working well with the e02-admin and e02 profiles

I enabled LogLevel: aws.LogLevel(aws.LogDebugWithHTTPBody) in the code, find below
trace

2023/09/18 07:02:01 DEBUG: Request ec2metadata/GetToken Details:
---[ REQUEST POST-SIGN ]-----------------------------
PUT /latest/api/token HTTP/1.1

Content-Length: 0
X-Aws-Ec2-Metadata-Token-Ttl-Seconds: 21600
Accept-Encoding: gzip
....

After I implemented workaround, change source_profile from e02 to d02
the issue is gone. The trace is like

2023/09/18 07:03:02 DEBUG: Request SSO/GetRoleCredentials Details:
---[ REQUEST POST-SIGN ]-----------------------------

User-Agent: aws-sdk-go/1.45.9 (go1.19.1; darwin; amd64)
X-Amz-Sso_bearer_token: *****
Accept-Encoding: gzip

Because I use sso federation in aws profile, I wonder why sdk is looking for ec2metadata/GetToken in this situation.

HenryXie1 · 2023-09-17T21:21:13Z

We tested on d02 profile which has same content as e02, it is working well.

In this case, it seems that the SDK is not correctly recognizing the SSO federation credentials only from e02 profile, causing it to fall back to the EC2 metadata provider.

but AWS CLI is working fine with the same profiles, this might be a bug in the SDK
Wonder anything special with the key word e02 in aws sdk go?

Hi @HenryXie1 ,

Thanks for all the details, this is indeed an interesting behavior.

If IRSA credentials fail, the logs would typically show a failed request to the OIDC identity provider and then to the STS AssumeRoleWithWebIdentity operation. Errors could include token validation issues, service errors, etc. Are you able to see any logs of errors with that credentials provider?

Another thought I have was for you to set the desired profile explicitly in the SDK and see if that helps with resolving the issue, or at least would surface some more helpful errors. You can check out this blogpost .

Let us know what you find.
Thanks,
Ran~

Hey @RanVaknin
Thanks for your reply
Here are some input I have

Are you able to see any logs of errors with that credentials provider?

no, do you know how to enable some debug trace for it?

Another thought I have was for you to set the desired profile explicitly in the SDK and see if that helps with resolving the issue, or at least would surface some more helpful errors. You can check out this blogpost .

I add below code to debug, but i don't see any output from sts client and error is also nil

client := sts.New(sess)
	fmt.Println("sts client info2:")
	fmt.Println("sts client:", *client)
	identity, err := client.GetCallerIdentity(&sts.GetCallerIdentityInput{})
	fmt.Println("sts client info3:")
	fmt.Println("sts identity:", *identity)

    if err != nil {
        fmt.Println("error:", err)
        os.Exit(1)
    }

    fmt.Printf(
        "Account: %s\nUserID: %s\nARN: %s\n",
        aws.StringValue(identity.Account),
        aws.StringValue(identity.UserId),
        aws.StringValue(identity.Arn),
    )

sts client info1:
sts client info2:
sts client: {0xc000423c00}
2023/09/21 16:03:10 DEBUG: Request ec2metadata/GetToken Details:

Content-Length: 0
X-Aws-Ec2-Metadata-Token-Ttl-Seconds: 21600
Accept-Encoding: gzip

After I change source_profile in e02-admin from e02 to d02(workaround)
The output is

❯ ~/github-cba/pksctl/bin/pksctl generate kube-config
sts client info1:
sts client info2:
sts client: {0xc000411c00}

It is weird that i don't see println for sts client info3

RanVaknin · 2023-09-21T20:45:09Z

Hi @HenryXie1,

We think this is an issue with how the SDK's INI loader parses numbers. @lucix-aws has raised a PR regarding a similar issue we saw on v2, and tested the ini parser with d02 as an argument without an issue, and then e02 and we saw an issue. It might be related.
Can you please wait for tomorrow's release, pull the latest version of the SDK, and see if this solves your issue?

Thanks,
Ran~

lucix-aws · 2023-09-22T19:48:00Z

@HenryXie1 --

Pursuant to @RanVaknin's comment above, release 1.45.15 has just been tagged, which should solve your issue.

HenryXie1 · 2023-09-22T20:36:11Z

Great, thanks @lucix-aws @RanVaknin

lucix-aws · 2023-09-23T20:42:29Z

Please let us know if that unblocks you so we can close this out or investigate further.

HenryXie1 · 2023-09-24T19:23:40Z

@lucix-aws I confirm the issue is fixed by upgrading aws go sdk to 1.45.15
