Be able to customize the public ip resolver script #137
Description
I'm using Rancher to deploy the docker images.
It comes with an internal DNS server, so I'm not using Consul.io and I'm disabling it with the correct env variable.
I wish to customize the public-hostname.sh script using the metadata service provided by Rancher:
http://rancher.com/docs/rancher/v1.6/en/rancher-services/metadata-service/
curl http://rancher-metadata/latest/self/host/hostname
What is the best option ?
- Inherits from the official image and add my custom script ?
- Patch the current script to support multiple metadata services (consul & rancher) and use an ENV variable to choose the right one ?
- Pass the command to execute as an ENV variable ?
