runtimevar

Simple wrapper around the Go Cloud runtimevar package

Example

package main

import (
	"context"
	"flag"
	"fmt"
	"github.com/sfomuseum/runtimevar"
	_ "gocloud.dev/runtimevar/awsparamstore"
	_ "gocloud.dev/runtimevar/constantvar"
	_ "gocloud.dev/runtimevar/filevar"
)

func main() {

	flag.Parse()

	ctx := context.Background()

	for _, uri := range flag.Args() {
		str_var, _ := runtimevar.StringVar(ctx, uri)
		fmt.Printf(str_var)
	}
}

Tools

$> go run cmd/runtimevar/main.go 'constant://?val=hello+world'
hello world

The following Go Cloud runtimevar services are supported by the runtimevar tool:

AWS Parameter Store

It is possible to load runtime variables from AWS Parameter Store using aaronland/go-aws-session credential strings. For example:

$> go run cmd/runtimevar/main.go 'awsparamstore://hello-world?region=us-west-2&credentials=session'
hello world

Valid aaronland/go-aws-session credential strings are:

Credentials for AWS sessions are defined as string labels. They are:

Label Description
env: Read credentials from AWS defined environment variables.
