tfstate

tfstate add-on package

This package extends config.Loader and provides functions to reference Terform tfstate values

Usage

tfstate pakcage include MustLoad and Load. for example: config.yaml has the following content

aws_account_id: '{{ tfstate "data.aws_caller_identity.current.account_id" }}'
vpc_id: '{{ tfstate "aws_vpc.main.id" }}'

The code to load this configuration is as follows:

package main

import (
    "fmt"

	"github.com/kayac/go-config"
	"github.com/kayac/go-config/tfstate"
)

func main() {
	loader := config.New()
	loader.Funcs(tfstate.MustLoad("./testdata/terraform.tfstate"))
	var c map[string]string
	if err := loader.LoadWithEnv(&c, "./config.yaml"); err != nil {
		fmt.Println(err)
		return
	}
	fmt.Println(c["aws_account_id"])
}

Load tfstate from local file.

Note

./testdata/terraform.tfstate is the same data as testdata used in https://github.com/fujiwara/tfstate-lookup
