project-request template

Description of problem:
We are trying to setup a 4.0 cluster with similar project quotas/limits/etc as our existing starter clusters.  We have created a "project-request" template in the openshift-config namespace.  When we apply the CR that references the template, we get different resources created based on whether the namespace is specified of not.

If we specify:
   name: "project-request"
then only the rolebindings are created.

If we specify:
   name: "openshift-config/project-request"
then all the resources (rolebindings, limits, quotas, networkpolicy, etc) are created, as expected.

If the ProjectRequestTemplate field requires a namespace, then if should be checked, verified, and fail accordingly (not silently). 

Version-Release number of selected component (if applicable):
oc v4.0.0-0.159.0
kubernetes v1.12.4+610027abd7
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://rhcos-west-1-api.rhcos.sandbox.openshift.com:6443
kubernetes v1.12.4+b367d26

How reproducible:

Steps to Reproduce:
1. Create a new 4.0 cluster
2. Create a template in the "openshift-config" namespace that creates any combination of limits, quotas, rolebindings, networkpolicy, etc. 
3. Apply a projects.config.openshift.io CR that references the template, *without* specifying a namespace, in step #2
4. Wait for all apiservices pods to restart
5. Switch users to a non-admin user, and create a project
5a. Observe that only rolebindings have been created
6. Switch back to kubeadmin
7. Edit/delete-apply a new CR *with* the "openshift-config" namespace specified
8. Wait for all apiservices pods to restart
9. Switch users to a non-admin user, and create a different project
9a. Observe that all the template resources have been created

Actual results:
Varies based on whether or not a namespace value is specified inside the "name" field

Expected results:
If namespace is required, then if should verify and fail accordingly, and/or not fail silently when unable to create resources defined in a template

Comment 2 Michal Fojtik 2019-02-20 12:04:36 UTC
// TemplateReference references a template in a specific namespace.
// The namespace must be specified at the point of use.
type TemplateReference struct {
	// name is the metadata.name of the referenced project request template
	Name string `json:"name"`

See: https://github.com/openshift/cluster-openshift-apiserver-operator/blob/b23dac5f69383c0f70ac86089ef4df6c484f64b0/vendor/github.com/openshift/api/config/v1/types_project.go#L22-L21

Once we have `oc explain config.openshift.io` hopefully this will be more clear.

Also we don't want to check whether the template exists or not in the operator.

Comment 3 David Eads 2019-02-20 14:19:56 UTC
I think I see it.  There's a piece of wiring missing.  Good catch.

I think I've got it here https://github.com/openshift/cluster-openshift-apiserver-operator/pull/149

Comment 4 zhou ying 2019-03-08 05:50:42 UTC
Confirmed with OCP:

[root@dhcp-140-138 yamlfile]#  oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.0.0-0.nightly-2019-03-06-074438   True        False         27h     Cluster version is 4.0.0-0.nightly-2019-03-06-074438

The result is : 

When I create the CR with projectRequestTemplate=openshift-config/project-request , then the openshift-apiserver's configmap is  "projectRequestTemplate": "openshift-config/openshift-config/project-request", then the project template not works well;

When I create the CR with projectRequestTemplate=project-request, then the openshift-apiserver's configmap is  "projectRequestTemplate": "openshift-config/project-request", the project template works.

Comment 6 Michal Fojtik 2019-03-12 10:59:57 UTC
Hmm strange, the admission validation should return error when you set this field to `openshift-config/project-request` (as it should only allow the name).
Can you paste the exact CR you created with this?

Fix: https://github.com/openshift/origin/pull/22311

Comment 10 zhou ying 2019-03-18 08:25:43 UTC
Confirmed with latest OCP, the issue has fixed:
[zhouying@dhcp-140-138 ~]$ oc version --short 
Client Version: v4.0.22
Server Version: v1.12.4+befe71b
Payload: 4.0.0-0.nightly-2019-03-15-063749

When try to create the project.config with 
    name: openshift-config/project-request
will failed with error: The Project "" is invalid: spec.projectRequestTemplate.name: Invalid value: "openshift-config/project-request": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

When create the project.config with     
    name: project-request

Will succeed.
