Important
For Linux stacks, if you want to associate an Amazon RDS service layer with your app, you must add the appropriate driver package to the associated app server layer, as follows:
Click Layers in the navigation pane and open the app server`s Recipes tab.
Click Edit and add the appropriate driver package to OS Packages. For example, you should specify mysql if the layer contains Amazon Linux instances and mysql-client if the layer contains Ubuntu instances.
Save the changes and redeploy the app.
