Error: Failed to get user environment user: Current requires cgo or $USER set in environment #266

Closed kwhitejr closed 3 years ago

I am attempting to deploy a SignalFX dashboard via Terraform from a Jenkins runner. I received the following error and it is not clear to me what is wrong (longer TRACE logs below):

Error: Failed to get user environment user: Current requires cgo or $USER set in environment
  on main.tf line 15, in provider "signalfx":
  15: provider "signalfx" {

Image: hashicorp/terraform:0.13.5 Jenkins: 2.235.1-alpine TF files and SFX credentials themselves are verified fine; I can deploy without issue from local machine. The same pipeline and image run AWS and Pagerduty providers without issue.

Trace logs:

The error log seems to be originating from here (provider.go): https://github.com/splunk-terraform/terraform-provider-signalfx/blob/main/signalfx/provider.go#L117-L119

// $HOME/.signalfx.conf second
// this additional variable is used for mocking purposes in tests
if HomeConfigPath == "" {
    usr, err := user.Current()
    if err != nil {
        return nil, fmt.Errorf("Failed to get user environment %s", err.Error())
    }
    HomeConfigPath = usr.HomeDir + HomeConfigSuffix
}

Temporary workaround: set image hashicorp/terraform:0.13.5 environment variable USER to any string.

It needs to be able to find a home directory. See https://github.com/splunk-terraform/terraform-provider-signalfx/issues/259#issuecomment-715544374
