ranch53

A simple service that updates Route 53 based on labels on Rancher services.

How does it work?

Currently the following two synchronisations are actioned:

Load Balancer Services that have the labels, dns_alias and dns_target will have a CNAME record created or updated in that R53 zone in the format of <dns_alias>. CNAME <dns_target>
Hosts that have the labels, tier and pool_zone will update an A record with each of their private IP addresses under the name, rancher-<tier>-pool.<pool_zone>

Limited use cases are supported currently. Please raise an issue so we can look at how to best add other uses.

Installation

Build

Static Binary

To build a fully static 64-bit Linux binary (useful for docker):

$ CGO_ENABLED=0 \
  GOOS=linux \
  GOARCH=amd64 \
    go build -a -installsuffix cgo -o bin/ranch53 .

Docker

Build the static binary per above, then the docker image with:

$ docker build -t flaccid/ranch53 .

Example usage:

(todo: this requires needed env vars)

$ docker run \
    -it \
    --env-file .env \
      flaccid/ranch53

Publish

$ docker push flaccid/ranch53

Run

$ go run main.go
