Directory structure

[barry8schneider]

I am just trying to understand the directory structure for this project. Especially the .go files under https://github.com/cloud-ark/kubeplus/tree/master/postgres-crd-v2

[devdattakulkarni]

main.go -> Starting point
controller.go -> Controller code for Postgres CRD
user.go -> Functions for performing User related actions on a Postgres instance
database.go -> Functions for performing Database related actions on a Postgres instance
utils.go -> Utility functions

./postgres-crd-v2/pkg/apis/postgrescontroller/v1/types.go -> Definition of Postgres CRD spec

The structure on the kubernetes sample controller issue 14 has the Controller's logic in another location. I am not sure where these files should live but in the root does not feel right. What do you think?

Create the Controller's logic
Now that all the required code has been generated we've got ourselves some nice options to perform some routine tasks:

./pkg/client/clientset/versioned/typed/samplecontroller/v1alpha1/samplecontroller_client.go which will act as our goto-structure to access any api-endpoint related to the CustomResource we created.

./pkg/client/clientset/versioned/typed/samplecontroller/v1alpha1/foo.go which will add the .Foo("") which in turn supplies an interface to operations like:

• List
• Get
• Watch

Good point.

Makes sense to move the go files in some sub-directory -- one option is to move them in the folder where types.go is defined.

In your setup, may be you can try it and see if that change would work or not. If it does then we can make the change here. You will probably need to change import statements in some of the files.

Rather than refactoring postgres-crd-v2, we can consider these points in any new Operator/custom controller that we will create.

Steps to create new custom controller are included in:
https://github.com/cloud-ark/kubeplus/blob/master/docs/setup/creating-operator.txt

One of the things that can be considered as part of this process is location of the source code files.

So closing this issue.
