📝 Summary

Summary by CodeRabbit

  • New Features

    • Configure CPU and memory requests and limits for the main Ansible execution environment container; resources are unset by default.
    • When ANSIBLE_FORKS isn’t explicitly configured, its default is calculated from CPU requests and limits, rounding fractional values up. If CPU resources can’t determine a value, the default is 5. Memory settings don’t affect the calculation.
    • Set ANSIBLE_FORKS through NodeSet environment variables or a selected ConfigMap to override the default.
  • Documentation

    • Added guidance on resource settings, fork calculation, configuration precedence, and when changes take effect.

Walkthrough

The NodeSet API adds resource requirements for the main Ansible EE container. Job creation applies those resources and selects ANSIBLE_FORKS from environment settings, ConfigMap values, or CPU resources. Tests and documentation cover these settings and selection behavior.

Changes

Ansible EE resources and fork defaults

Layer / File(s) Summary
Resource API and CRD contracts
api/dataplane/v1beta1/common.go, api/dataplane/v1beta1/openstackdataplanenodeset_types.go, api/dataplane/v1beta1/zz_generated.deepcopy.go, api/bases/dataplane.openstack.org_openstackdataplanenodesets.yaml, config/crd/bases/dataplane.openstack.org_openstackdataplanenodesets.yaml, bindata/crds/crds.yaml, config/samples/dataplane_v1beta1_openstackdataplanenodeset.yaml, docs/assemblies/dataplane_resources.adoc
The NodeSet API and schemas add optional ansibleEEResources for the main Ansible EE container. The sample configures CPU and memory requests and limits.
Job resource propagation and fork selection
internal/dataplane/util/ansibleee.go, internal/dataplane/util/ansible_execution.go, internal/dataplane/util/ansible_forks.go
Job construction applies the configured resources to the main container. Fork selection preserves explicit environment or ConfigMap values. Otherwise, it derives a value from CPU settings or uses the fallback.
Fork behavior and Job validation
internal/dataplane/util/ansible_forks_test.go, test/functional/dataplane/openstackdataplanenodeset_controller_test.go, test/kuttl/tests/dataplane-service-config/*, test/kuttl/tests/dataplane-deploy-global-service-test/*, test/kuttl/tests/dataplane-deploy-multiple-secrets/*, test/kuttl/tests/dataplane-deploy-no-nodes-test/*, test/kuttl/tests/dataplane-deploy-tls-test/*, test/kuttl/tests/dataplane-extramounts/*, test/kuttl/tests/dataplane-service-custom-image/*, test/kuttl/tests/dataplane-service-failure/*, docs/assemblies/dataplane_performance_tuning_large_scale.adoc
Unit, functional, and KUTTL tests cover fork selection, ConfigMap lookup errors, resource propagation, and generated Job environments. The performance guide documents CPU-based defaults and setting precedence.

Grant the operator permission to read ConfigMaps.

When a Deployment selects an existing Ansible EE ConfigMap without an explicit ANSIBLE_FORKS environment variable, addDefaultAnsibleForks calls Get before creating the Job. The deployed operator-role has no configmaps permission, so this call returns Forbidden and AnsibleExecution exits before JobForOpenStackAnsibleEE.

Any reason we want this to be 8 from ansible default 5? This is kind of silent default change.

Raising the default was part of the initial Jira. But yes, it should be mentioned in the commit message and a release note if we do change it.
5 just seems pretty low. I think we could default to even higher than 8. WDYT?

I guess it depends on how aee pods would be scheduled in a cluster, now that one can run them in parallel with dependency and there can be number of nodesets in a deployment. With 10/20 nodes default forks would be ok unless we've scale testing data or feedback from the field that says otherwise. But 5-8 jump should be fine.

I switched it to 5, just to minimize the change. We can revisit if we want to raise it.

Maybe we can simplify this? Do we need the max cap and sign error here? Also, <=0 means "no usable CPU" and if caller omits ANSIBLE_FORKS ansible's own default applies?

if ANSIBLE_FORKS is absent from the NodeSet Env and the ConfigMap for ansible settings, then fallbackAnsibleForks (currently set to 8) is used.

By simplifying, do you mean just ignore the errors and return fallbackAnsibleForks instead of 0 and an error? I think that would be ok, but it might be unexpected and hide bad user input.

Yeah, I meant we can drop the pre-validation and follow k8s semantics here, zero is a valid CPU value to the API (only Sign() < 0 is rejected at admission), so erroring means we're disallowing something k8s accepts. Negatives don't need our check either, Job creation fails at admission anyway. I was thinking of something like below

func defaultAnsibleForks(resources corev1.ResourceRequirements) (int64, bool) {
   request, hasRequest := usableCPU(resources.Requests)
   limit, hasLimit := usableCPU(resources.Limits)
   chosen, ok := limit, hasLimit
   if hasRequest && (!ok || request.Cmp(limit) < 0) {
      chosen, ok = request, true
   }
   if !ok {
      return 0, false
   }
   // Quantity.Value() is the ceiling of the core count, which is what forks want.
   return chosen.Value(), true
}

func usableCPU(list corev1.ResourceList) (resource.Quantity, bool) {
   cpu, found := list[corev1.ResourceCPU]
   return cpu, found && cpu.Sign() > 0
}

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Reject unsupported claims in AnsibleEEResources.

ResourceRequirements.Claims must reference an entry in the Pod's spec.resourceClaims. The Job builder copies the NodeSet value to the container but does not populate PodSpec.ResourceClaims. Kubernetes validation can therefore reject the Job with a missing resource-claim reference.

Reject non-empty claims at the NodeSet API boundary.

Yeah, I meant we can drop the pre-validation and follow k8s semantics here, zero is a valid CPU value to the API (only Sign() < 0 is rejected at admission), so erroring means we're disallowing something k8s accepts. Negatives don't need our check either, Job creation fails at admission anyway. I was thinking of something like below

func defaultAnsibleForks(resources corev1.ResourceRequirements) (int64, bool) {
   request, hasRequest := usableCPU(resources.Requests)
   limit, hasLimit := usableCPU(resources.Limits)
   chosen, ok := limit, hasLimit
   if hasRequest && (!ok || request.Cmp(limit) < 0) {
      chosen, ok = request, true
   }
   if !ok {
      return 0, false
   }
   // Quantity.Value() is the ceiling of the core count, which is what forks want.
   return chosen.Value(), true
}

func usableCPU(list corev1.ResourceList) (resource.Quantity, bool) {
   cpu, found := list[corev1.ResourceCPU]
   return cpu, found && cpu.Sign() > 0
}

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Fix compile error: defaultAnsibleForks returns (int64, bool), not an error.

Line 58 assigns the second return value (a bool) to err, which already has type error. This does not compile. The unit tests in internal/dataplane/util/ansible_forks_test.go still call defaultAnsibleForks with the old (int64, error) signature.

The function also now returns ok == false when no usable CPU is set. The caller must apply fallbackAnsibleForks in that case. The constant is currently unused.

The tests expect errors for zero and negative CPU values. Align the tests with the simplified semantics from the earlier review. With those semantics, zero or negative values fall back to the default.

The changed method does not return error but a boolean. Also tests need to adapt.

This is not used anywhere now.

Sets the default ansible forks to 5 if not otherwise set.

Add NodeSet EE resource requests and limits and derive the default fork
count from CPU allocation while preserving explicit environment
overrides.

Correct the no-CPU fallback to 5.

The implementation uses 5 when no usable CPU request or limit exists. This example comment states 8, so readers may apply the wrong fallback value.

🐛 Suggested fix
-    # Override CPU-derived parallelism when needed (fallback without CPU: 8)

I would not have liked to maintain this constant though as a fallback as it would be disconnected from ansible default. If we want to control this in the future, probably makes sense.
