Rancher for CI

Because I needed a plugin that could upgrade only a given service's docker image version.

Attention: This pluging supports only Rancher Environment API v1.

Parameters

• endpoint: the environment API endpoint
• access key: a valid environment API access key
• secret key: a valid environment API secret key
• service: the services which you want to upgrade
• version: the version to which you want to upgrade

Using as a node module

Install it (yarn add @eclass/rancher-for-ci or npm i -s @eclass/rancher-for-ci) then use as in the example below:

const Rancher = require('@eclass/rancher-for-ci')

const client = new Rancher(
  'https://rancher.domain.com/v1/projects/{ID}',
  'MyAccessKey',
  'MySecretKey'
)

;(async () => {
    await client.upgrade('my-stack/my-service', '1.0.0')
})()

Using as a Drone CI plugin

pipeline:
    deploy:
        image: rwillians/rancher-for-ci
        service: my-stack/my-service
        version: latest
        secrets: [ rancher_url, rancher_access_key, rancher_secret_key ]

 pipeline:
     deploy:
         image: rwillians/rancher-for-ci
         service: my-stack/my-service
-        version: latest
+        version: v1.0.10
+        version_prefix: v
         secrets: [ rancher_url, rancher_access_key, rancher_secret_key ]

pipeline:
    deploy:
        image: rwillians/rancher-for-ci
        endpoint: https://rancher.domain.com/v1/projects/{ID}
        access_key: MyAccessKey
        secret_key: MySecretKey
        service: my-stack/my-service
        version: 2.0.1-rc.1

Overriding verson on drone deploy command

You can override the "verion" property buy passing a "VERSION" parameter to deploy command. drone deploy owner/repo {BUILD} {ENVIRONMENT} -p VERSION=2.0.0.

Using DRONE_TAG/CI_TAG as version

If you omit "version" propperty and do not pass the override version parameter, the plugin will try to use "DRONE_TAG" and "CI_TAG" as version.

 pipeline:
     deploy:
         image: rwillians/rancher-for-ci
         service: my-stack/my-service
-        version: v1.0.10
         version_prefix: v
         secrets: [ rancher_url, rancher_access_key, rancher_secret_key ]

drone deploy owner/repo {BUILD} {ENVIRONMENT}

Note that you should use a build resultant of a tag event, otherwise there won't be any "DRONE_TAG" or "CI_TAG" which will result in failure.
