Question

Deploy Rails app to digitalocean using caprover

I’m trying to deploy my Rails 5 app to digital ocean using CapRover. The problem is when some gems require some other packages to be installed, like ovirt-engine-sdk, that needs xml2-devel. When I run:

caprover deploy

It raises the next error:

extconf.rb:29:in `<main>': The "libxml2" package isn't available. (RuntimeError)

I’ve tried to install them manually from the digital ocean console, but it doesn’t work. Investigating a little I found that I might need to use a Dockerfile instead.

How can I deploy my project and indicate the dependency libraries needed for the gem packages?

Hi there,

There was a similar issue raised on the official GitHub repository here:

https://github.com/caprover/caprover/issues/324

People are suggesting defining a captain-definition file and adding the install command in there.

For more information on how to do that, you could take a look at the following page:

https://caprover.com/docs/captain-definition-file.html#convert-dockerfile-to-captain-definition

Let me know how it goes! Regards, Bobby
