How do I run a One Click App on a deployed Linode?
While there is no way to directly deploy a One-Click App on a Linode that's already been deployed, there is still a way to do this. One-Click Apps use StackScripts to deploy their services.
Since those scripts are public-facing, you can copy their code and then run the script locally on a Linode that's already been deployed. You'll need to take some things into account before it will work, however. Those considerations are outlined in this Community post. As an example, you can find our OpenVPN One-Click App here.
