If you are an existing Cloud Foundry user, your experience with Korifi will be pretty familiar. However, the underlying implementations of the Cloud Foundry API are quite different. This section focuses on the underlying Kubernetes representations of common Cloud Foundry constructs.
How are orgs, spaces, and roles implemented?
Orgs and spaces will each have their own corresponding namespace. The name corresponds to the GUID of the org/space.
kubectl get namespaces
NAME STATUS AGE
... Active 47h
cf-org-d255d9f0-962e-4122-bd6a-422110b15e0d Active 23h
cf-space-0eee9ef7-ff1e-4a80-842f-a53179768b6f Active 23h
Fetching the GUID for the org:
cf org --guid tutorial
Fetching the GUID for the space:
cf space --guid dev
Roles are mapped to a RoleBinding of a ClusterRole object:
kubectl get rolebindings -n cf-space-0eee9ef7-ff1e-4a80-842f-a53179768b6f
NAME ROLE AGE
cf-8d87de46bc2d38fe0c96aa24cd3191d7d4528ca101b07ecbd9d3ef3fecb53de5 ClusterRole/korifi-controllers-space-developer 23h
cf-dc43e0e171a16401f2a495e6d38f32434a2958dd430aa6ffe792d2491e4a361e ClusterRole/korifi-controllers-space-manager 23h
default-admin-binding ClusterRole/korifi-controllers-admin 23h
What does an app look like?
To view this information using
kubectl, you must first fetch the space GUID to determine the namespace name.
cf space --guid dev
You can then use
kubectl to view the details. For example, in the below block, there is one pod for each instance (two are running). And the pod marked “Completed” was used during staging.
kubectl get pods -n cf-space-0eee9ef7-ff1e-4a80-842f-a53179768b6f
NAME READY STATUS RESTARTS AGE
d60fe7b7-f080-4caa-a26b-b811c88d766e-cf--cbc52994d8-0 1/1 Running 0 17h
d60fe7b7-f080-4caa-a26b-b811c88d766e-cf--cbc52994d8-1 1/1 Running 0 16h
ef3d386d-1cea-46bf-8191-fedcedba8532-build-1-build-pod 0/1 Completed 0 17h
To view the custom resource:
kubectl get cfapp -n cf-space-0eee9ef7-ff1e-4a80-842f-a53179768b6f
NAME DISPLAY NAME AGE
d60fe7b7-f080-4caa-a26b-b811c88d766e sample-app 17h
Cloud Foundry Resource Mappings
If you would like a more complete picture of Cloud Foundry resources in Korifi refer to the table of Cloud Foundry to Kubernetes resource mappings. There are plenty of other resources to dive into, should you choose. However, if you are a Cloud Foundry user, you likely don’t care too much about the underlying implementations. Happy pushing!
