It looks like you have a two-container setup rather than the usual one container called `app`.

For a two-container setup I believe you would need to run:

`./launcher bootstrap web_only && ./launcher destroy web_only && ./launcher start web_only`

Though usually people with a two-container setup are aware of the difference. Is this the first time you’ve updated since you installed?
