Does a Rancher upgrade.

You will need to create an API access token and secret for Rancher.

If you wanted to deploy swaggy/awesome:3.0, you'd set DOCKER_IMAGE=swaggy/awesome, and TAG=3.0.

If your tag is unique each deploy, you should set USE_TAG to true. But if you always deploy the same tag (i.e. latest), you should set use_tag to false. use_tag just sets the rancher service name to include the tag, for example awesome-3.0 -> awesome-3.1. But if your tag is not unique, then a random number will be generated for you. Rancher enforces that the service has to have a new unique name on every deploy.

If you use in-place mode, then you don't need new unique names. Just set USE_TAG to false and IN_PLACE to true.

The rancher URL needs to be your full url including the project id. You can get the url on your api key page - it's the highlighted text next to "Endpoint". Make sure you create the api key in the environment you want to use. Note: Don't include http/s:// in the url - it's added through a flag (HTTPS).
