Briefing

This project try to solve the problem of upgrading Rancher stack services without the need of using the UI.

Why

Because one of the most useful thinks of a PaaS is to automate the deployment process thought your C.I. system.

With this script you can do that.

Installation

Installation process is so easy:

Usage

The script is self-explained, to get help, only use -h option:

> rancher-upgrader -h

                           RANCHER_URL -a RANCHER_ACCESS_KEY -k
                           RANCHER_SECRET_KEY [--retires MAX_RETRIES]
                           [--sleep]

Extra options:
  --retires MAX_RETRIES
                        maximum number of retries to check upgrade process
  --sleep               sleep time while checking upgrading process

If the upgrade fails, automatically It will do a rollback
Rancher upgrader will do the complete upgrade process, including the confirmation of the upgrade process when the upgrading process was finished
