drone-rancher-stack-v1

A drone.io Rancher Stack plugin

Plugin Details

• Rancher v1.6 stable compatible
• Rancher-compose v0.12.5

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. Keep it separate from your app to enable other services to leverage it. Clone it via command into a directory (see Drone Pipeline Example) -- 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

Usage

The plugin requires the following

• image: dubc/drone-rancher-stack-v1
• url: rancher.domain.com
  • The url where your rancher resides
• stack: app-staging
  • This stack must already exist in your rancher environment
• accesskey: RANCHER_ACCESS_KEY
  • Your Rancher environment Access_Key
• secretkey: RANCHER_SECRET_KEY
  • Your Rancher environment Secret_Key
• pull: true
  • Makes sure you get the latest plugin version

Notes

• Rancher compose is pre-configured to force stack upgrade which will also create the stack if it doesn't exist
• Rancher Compose 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
