In `@config/rbac/activation_job_namespace_role.yaml`:
- Around line 1-26: The ClusterRole eda-activation-job-namespace-manager
currently allows create/update/patch/delete on resources roles and rolebindings
across all namespaces, which grants the operator ServiceAccount cluster-wide
RBAC management; update the project documentation and operator
security/threat-model notes to explicitly record that
eda-activation-job-namespace-manager grants these cluster-scoped verbs on
resources roles and rolebindings, why this broad scope is required for dynamic
target namespaces, and list mitigation/alternatives (e.g., dynamic ClusterRole
provisioning via an admission webhook or dedicated RBAC controller) so reviewers
and deployers are aware of the elevated privilege and possible hardening paths.
In `@roles/eda/tasks/deploy_eda.yml`:
- Around line 48-61: The cleanup task never deletes RBAC because it uses
combined_activation_worker.activation_job_namespace (which is empty when
cleared) and _previous_activation_job_namespace is never set; fix by first
capturing the existing activation namespace into
_previous_activation_job_namespace (use a set_fact immediately after loading the
CR/ConfigMap where combined_activation_worker.activation_job_namespace is read)
and then change the k8s task's namespace to use
_previous_activation_job_namespace and adjust the when to check
_previous_activation_job_namespace | default('') | length > 0 and
combined_activation_worker.activation_job_namespace | default('') | length == 0
so the Role/RoleBinding deletion runs against the old namespace.
In `@roles/eda/templates/eda-activation-job-namespace-rbac.yaml.j2`:
- Around line 11-46: The Role's rules for resources "secrets", "pods",
"pods/log", "services", and "jobs" are missing the "update" verb and will cause
403s when the EDA server performs HTTP PUT updates; modify each corresponding
rule in the template (the rules blocks that list apiGroups: "" for
secrets/pods/pods/log and services, and apiGroups: batch for jobs) to include
"update" in the verbs array so the Role permits update operations.

Read EDA_ACTIVATION_JOB_NAMESPACE environment variable in _set_namespace() as an override before falling back to the ServiceAccount token namespace file. This allows the eda-server-operator to direct activation job pods into a separate Kubernetes namespace for security isolation, resource quotas, and NetworkPolicy boundaries.

@amasolov I don't understand the reason for setting ignore_errors to true on this task. won't the module's absent idempotency be enough, along with the when guards?

@kaiokmo You're right, state: absent already handles the "not found" case gracefully, and the when guards prevent other runs. Removed ignore_errors so legitimate failures (permission issues, API errors) surface properly.

#362 just merged NetworkPolicies with default-deny. The eda-api and postgres NP templates allow activation job pods via bare podSelector: {app: eda}, which won't match pods in a different namespace.
You'll need to add conditional namespaceSelector to both NP templates when activation_job_namespace is set, e.g.:
{% if combined_activation_worker.activation_job_namespace | default('') | length > 0 %}
- namespaceSelector:
matchLabels:
kubernetes.io/metadata.name: '{{ combined_activation_worker.activation_job_namespace }}'
podSelector:
matchLabels:
app: eda
{% else %}
- podSelector:
matchLabels:
app: eda
{% endif %}Without this, rulebook execution (websocket), token refresh (API), and event stream activations (pg_notify) will fail when jobs run in a separate namespace.

@kaiokmo Done. Rebased against main, added conditional namespaceSelector to both the eda-api and postgres NetworkPolicy templates for cross-namespace activation job pods, and reordered the deploy tasks so the ConfigMap update runs after the RBAC migration. All checks are green.

Add activation_job_namespace field to the activation_worker section of the EDA CRD. When set, the operator injects EDA_ACTIVATION_JOB_NAMESPACE into the activation worker ConfigMap and creates a Role + RoleBinding in the target namespace so the EDA ServiceAccount can manage Jobs, Pods, Secrets, and Services there. Changes: - CRD: new optional string field activation_worker.activation_job_namespace - Role defaults: activation_job_namespace defaults to empty string - ConfigMap template: conditionally sets EDA_ACTIVATION_JOB_NAMESPACE - New RBAC template for cross-namespace Role and RoleBinding - Deploy task: applies/removes cross-namespace RBAC conditionally - ClusterRole + ClusterRoleBinding for operator to manage RBAC in the target namespace Closes ansible#344 Signed-off-by: Alexey Masolov <amasolov@redhat.com> Co-authored-by: Cursor <cursoragent@cursor.com>

…espace changes Move the lookup of _previous_activation_job_namespace to run before the ConfigMap is applied, so the old value is read before it gets overwritten. Also widen the RBAC cleanup condition to trigger whenever the previous namespace differs from the new one (not just when the new value is empty), so changing from namespace A to B correctly removes orphaned Role and RoleBinding from A.

Add the escalate verb on the roles resource in the eda-activation-job-namespace-manager ClusterRole. Kubernetes RBAC escalation prevention blocks creating a Role that grants permissions the creator doesn't hold. The escalate verb is the standard mechanism to permit this without granting the operator broad cluster-wide access to pods, secrets, services, and jobs. Also moves the _previous_activation_job_namespace lookup to run before the ConfigMap is applied (so the old value is captured before overwrite) and widens the RBAC cleanup condition to trigger on any namespace change, not just removal. Signed-off-by: Alexey Masolov <amasolov@redhat.com> Co-authored-by: Cursor <cursoragent@cursor.com>
The escalate verb fixed Role creation, but creating a RoleBinding that references a Role with elevated permissions also requires the bind verb on the roles resource.

…ivation jobs When activation_job_namespace is set, activation Job pods run in a different namespace. The default-deny NetworkPolicies from ansible#362 use bare podSelector which only matches pods in the same namespace, blocking websocket, API, and pg_notify traffic from cross-namespace job pods. Add conditional namespaceSelector to eda-api and postgres NetworkPolicy templates so ingress rules match activation job pods regardless of which namespace they run in.

Move the env-properties ConfigMap update to run after the cross-namespace RBAC create/delete tasks. Previously, the ConfigMap was updated first, so if the RBAC operations failed the next reconciliation would read the new namespace as _previous_activation_job_namespace and skip cleanup of the old Role and RoleBinding.

Operators running EDA on shared clusters need activation job pods (which run user-supplied rulebooks and decision environments) isolated from the EDA control plane. A dedicated namespace enables independent ResourceQuota, LimitRange, and NetworkPolicy controls.
