This is a little program written in Go that takes the WAN ip of your current infrastructure to update a hostname hosted on Amazon Route53.
One of the main reasons to choose Go to develop this program was the fact that Go can build executable binaries, which makes installation very easy. Secondly with Go it's also very easy to cross compile the program for different platforms.
To make a binary just run:
go build dyndns_route53.go
This will result in an executable binary named dyndns_route53.
This real power however is that you can cross compile the code for a number of
platforms.
Personally I have this program running on my (Synology) NAS.
This NAS is running Linux and has a x86-64 architecture. In order to
get the program running on that device you need to cross compile it for that specific platform.
To achieve this, you have to specify two extra parameters on the build command:
GOOS and GOARCH, you can find the appropriate values for
these variables here.
Here's how I build an executable binary for my NAS:
# env GOOS=linux GOARCH=amd64 go build dyndns_route53.go
Put a file named config.json in the same directory as you executable. A file named config.example is included in the repository to make your life easy. It looks like this:
{
"aws_access_key_id": "ABC...",
"aws_secret_access_key: "XYZ...",
"hosted_zone_id": "A1..",
"fqdn": "www.example.com"
}
The program will write its output to a file named dyndns.log under the same directory as you executable.
Test and run locally:
go build dyndns_route53.go
go run dyndns_route53.go
