drone-rancher-stack-v1

A drone.io Rancher Stack plugin to deploy/update an entire Rancher stack (not just a single service).

Plugin Details

Note: Rancher v2 will be a new plugin once v2.1 stable is released. See notes at bottom.

Requirements

A repo that contains your Rancher stack (I put mine inside of a folder called 'stack' -- docker-compose.yml -- rancher-compose.yml
Rancher Environment set-up with at least one active host
Rancher Environment set-up with a stack (empty or not)
Rancher Environment Access and Secret Keys

Secret Reference

Optional secrets

rancher_accesskey : Your Rancher environment Access_Key

rancher_secretkey : Your Rancher environment Secret_Key

Parameter Reference

The plugin requires the following:

image : dubc/drone-rancher-stack-v1

url : The url where your rancher resides. E.g http://rancher.domain.com

stack : This stack must already exist in your rancher environment. E.g app-staging

accesskey : Your Rancher environment Access_Key

secretkey : Your Rancher environment Secret_Key

pull : Makes sure you get the latest plugin version. E.g true

Notes

Rancher CLI is pre-configured to force stack upgrade which will also create the stack if it doesn't exist
Rancher CLI is baked into the plugin container and isn't configurable as it is the latest for the Rancher 1.6 stable
Future versions will not take into account Rancher 2.1, I will create a new plugin for it called dubc/drone-rancher-stack-v2
