Tofu Sniffer

Sniff which tool was used to start a OpenTofu/Terraform Provider.

The OpenTofu/Terraform provider process is a child process of tofu or terraform. This allows using the parent processes PID to find out the name of the process (and thus tool) that started the provider server.

Usage

The tf.Sniff() function can be used when configuring a provider to, for example, include the tool and its version in the user-agent value.

func (p *SomeProvider) Configure(ctx context.Context, req provider.ConfigureRequest, resp *provider.ConfigureResponse) {
	version := tf.Sniff(req.TerraformVersion)
	userAgent := fmt.Sprintf("terraform-provider-some/%s%s", p.version, version.UserAgentPostfix())
	// ...
}
