 #### Stacks
 A stack is the configuration of a runtime that can be used to power a workspace. Users choose the stack that powers a workspace within the user dashboard. Stacks have a recipe that defines how the container should be created and also meta data that defines the tags associated with the stack. Tags define how the stack is presented in the stack library and also filters out the available project templates that a user sees when creating a project.
