I am new to Concourse
Can someone please help me understand the difference between Resource and Resource Type in simple words?
Apparently, documentation is not helping me.
Think about a resource as an object and a resource type as a class.
Resource types are docker images that can take a bunch of source parameters.
Resources are instantiations of these images with specific parameters.
Resources generate versions which can serve as inputs or outputs of your tasks.
For example, a built-in resource type git can be instantiated into a resource code-repo by taking a specific github URI and branch as params.
From here on out, every time a commit shows up in the code-repo resource it may serve as an input to tasks in a job.
