Bundle install fails after adding gem "mysql2" and gem "reverse_markdown"

Migration
1

I’m trying to add “mysql2” and “reverse_markdown” to my fresh discourse container in “Gemfile” to migrate data with the ipb script.

bundle config unset deployment
bundle install

results with:

An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.

In Gemfile:
  mysql2

Bitnami is not supported.

You need to add the required libraries for mysql inside the container or machine running the import.

For a standard install you can use this template, or contrive to do it yourself inside the bitnami container. Or you can use a Install Discourse for development using Docker (there are also guides for Mac, Windows, and Linux).

Ah, a little bit weird. I thought bitnami is the official version.

The standard install is the official version. The bitnami image is developed and supported by bitnami, and very few people here have used it. If you need help with the Bitnami version, you’ll need to ask them about it.
