OpenShift cloud-credential-operator CredentialsRequest namespace RBAC permissions create get list watch security policy documentation
💡 Result:
The OpenShift Cloud Credential Operator (CCO) utilizes RBAC permissions to manage CredentialsRequest resources and provision cloud credentials [1][2][3]. ### RBAC Permissions for the Cloud Credential Operator The CCO controller requires cluster-wide permissions to monitor, reconcile, and act upon CredentialsRequest custom resources [1][4]. According to the operator's source code, the controller is granted the following RBAC verbs for credentialsrequests and its related status/finalizer resources: - get [1] - list [1] - watch [1] - create [1] - update [1] - patch [1] - delete [1] Additionally, the controller requires permissions to manage supporting cluster resources, including: - Core resources: secrets, configmaps, and events (get, list, watch, create, update, patch, delete) [1]. - Namespaces: get, list, watch [1]. - Config.openshift.io resources: clusterversions, infrastructures, dnses, clusteroperators (with varying verbs including get, list, watch, create, and update) [1]. ### CredentialsRequest Namespace Permissions CredentialsRequest resources are namespace-scoped [5][6]. Components (such as Operators) that need to request cloud credentials must have the appropriate RBAC permissions within their specific namespace to: - Create CredentialsRequest objects [7]. - Read or mount the resulting Secret object generated by the CCO [7][2]. The CCO itself watches for these requests across the cluster [4][2]. When a request is created in a namespace, the CCO reconciles the object and manages the corresponding cloud provider resources, storing the resulting credentials in the secret specified in the secretRef field of the CredentialsRequest [2][8]. ### Security and Policy The CCO operates in specific modes—mint, passthrough, or manual—which dictate how it handles cloud credentials and security requirements [3]. To enforce security policies, such as egress control, the CCO may also utilize NetworkPolicies to restrict traffic, ensuring that communication between the operator and cloud provider APIs or the Kubernetes API is explicitly permitted [9]. The operator adheres to the principle of least privilege by using dedicated ServiceAccounts for its components, such as pod identity webhooks, with scoped RBAC permissions [4].

site:github.com/openshift/cloud-credential-operator CredentialsRequest admission validation providerSpec statementEntries namespace mint mode arbitrary permissions
💡 Result:
The CredentialsRequest resource is a primary component of the OpenShift Cloud Credential Operator (CCO), designed to enable cluster components to request fine-grained cloud credentials [1][2]. Key aspects of the CredentialsRequest architecture include: 1. ProviderSpec and StatementEntries: The CredentialsRequest specification includes a providerSpec field, which is an object containing cloud-specific configuration [3][4]. For supported cloud providers like AWS, this often includes statementEntries, which define the granular policy permissions requested by the workload [5]. The operator uses these definitions to ensure the requested permissions match the cloud resources [5]. 2. Mint Mode: In Mint mode, the CCO uses an admin-level cloud credential (typically stored in the kube-system namespace) to dynamically create new, restricted cloud users or roles for each CredentialsRequest [1][2]. This allows the operator to provision fine-grained, least-privilege credentials for specific workloads [1]. 3. Admission Validation: The CCO performs validation to ensure that CredentialsRequests are correctly formed [6]. If the providerSpec is empty or misconfigured, the operator will reject the request or encounter errors during reconciliation [6]. The operator also reconciles the desired permissions defined in the CredentialsRequest against the actual cloud environment, ensuring that the necessary policies are attached or created [5][2]. 4. Namespace Scope: While the Cloud Credential Operator itself may monitor a central namespace for its own status tracking, CredentialsRequest objects are namespaced resources [3][4]. This allows components across different namespaces to request their own specific credentials [1][2]. 5. Arbitrary Permissions: The use of statementEntries allows for the expression of arbitrary (yet structured) cloud provider policies [5]. By defining these within the CredentialsRequest, users can request the exact scope of access required for a workload, which the operator then enforces in the underlying cloud infrastructure (in Mint mode) [1][2]. The system is designed to maintain a valid state even if root admin credentials are removed after installation, provided that existing CredentialsRequests remain fulfilled [1][2].

🌐 Web query:
site:github.com/openshift/cloud-credential-operator CredentialsRequest namespace openshift-cloud-credential-operator controller source
💡 Result:
The CredentialsRequest custom resource in OpenShift is managed by the cloud-credential-operator [1][2]. Within the operator's source code, the primary reconciliation logic for these objects is located in the pkg/operator/credentialsrequest/credentialsrequest_controller.go file [3][4]. Key details regarding the source and management of CredentialsRequest include: 1. Controller Source: The reconciliation logic is implemented in the ReconcileCredentialsRequest struct defined in pkg/operator/credentialsrequest/credentialsrequest_controller.go [4]. This controller is added to the manager via the AddWithActuator function, which initializes the reconciler with a platform-specific actuator [4]. 2. Actuator Pattern: The controller delegates cloud-provider-specific operations (such as creating, deleting, or updating credentials) to an Actuator interface defined in pkg/operator/credentialsrequest/actuator/actuator.go [5]. Different cloud providers (AWS, Azure, GCP, etc.) implement this interface to interact with the underlying cloud APIs [6]. 3. Namespaces: - The cloud-credential-operator itself runs in the openshift-cloud-credential-operator namespace [7][1]. - While CredentialsRequests can be created in various namespaces, the operator often monitors them centrally [1][8]. Official documentation and best practices recommend that cluster components create their CredentialsRequests within the openshift-cloud-credential-operator namespace [1][2]. 4. Reconciliation Logic: The controller watches for changes to CredentialsRequest objects [4]. It also watches Secret objects that have specific annotations (e.g., credentialsrequest.cloudcredential.openshift.io) to trigger reconciliations when relevant credentials change [3].

Scope CredentialsRequest RBAC to openshift-cloud-credential-operator. ensureCredentialsRequest only reads and creates the fixed request in that namespace, but the controller ServiceAccount receives get, list, watch, and create through a ClusterRoleBinding. In mint mode, this permits requests in every namespace and allows a compromised identity to submit broader providerSpec permissions. Generate a namespaced Role and RoleBinding, remove the unnecessary verbs, and update config/rbac/role.yaml and bundle/manifests/bgp-cloud-connector.clusterserviceversion.yaml.

To be dropped before this merges. openshift/bgp-cloud-connector#91 has the operator ask the cloud credential operator for AWS credentials when the pod has none, which is the case on an ordinary IPI cluster. Two things have to be true for that to work and neither can be established from a laptop: CCO must be in a mode where it mints, and the minted key must reach the route server API in this account. Rehearsals build bgp-cloud-connector at main, so the operator under test does not carry openshift#91 and cannot answer this itself. Applying the same CredentialsRequest by hand and calling EC2 with what comes back answers it now, and separately from whether that PR is any good.
The operator called LoadDefaultConfig and hoped. That works on ROSA, where the pod identity webhook injects a web identity token once the ServiceAccount is annotated, and nowhere else: on an ordinary IPI cluster the chain finds nothing, sts:GetCallerIdentity fails, and the CUDNBgpConfig goes Degraded with CloudCredentialsInvalid on a cluster where nobody has done anything wrong. ResolveCredentials now asks the SDK first and the cluster second. If the pod already has credentials they are used and the cluster is left alone, which keeps ROSA exactly as it was. If it has none, the operator creates a CredentialsRequest for itself carrying the nine EC2 actions it actually uses, and reads the secret the cloud credential operator mints into its own namespace. Deciding between the two by retrieving from the SDK's chain, rather than by reading the Infrastructure CR or sniffing AWS_ROLE_ARN, keeps the decision on the thing that matters. LoadDefaultConfig assembles a chain without consulting it, so only a retrieval answers the question. Minting takes a few seconds, and during them the operator is not broken. platform.ErrCredentialsPending says so, and Phase 3 waits it out the way Phase 2 waits for FRR: Configuring, CloudEndpointsDiscovered=False with reason WaitingForCloudCredentials, requeue in ten seconds. A secret that exists but carries no usable keys is the opposite -- the cluster has answered and the answer is no good -- so that is an error, and it names the ServiceAccount to annotate in case the cluster turns out to use STS. The secret permission is a namespaced Role rather than a cluster-wide one: the operator reads one secret, its own. POD_NAMESPACE comes from the downward API because OLM installs wherever the administrator asks, and the constant covers running the manager from a desk.

🌐 Web query:
OpenShift Cloud Credential Operator CredentialsRequest spec.secretRef namespace existing request reconciliation
💡 Result:
In OpenShift, the Cloud Credential Operator (CCO) uses the spec.secretRef field in a CredentialsRequest custom resource to define where the generated credentials should be stored [1][2]. The secretRef contains both the name and namespace of the target Secret [3][4]. Regarding the reconciliation process and namespace handling: 1. Cross-Namespace Support: The Secret referenced by secretRef does not need to be in the same namespace as the CredentialsRequest resource [1][2]. It is common practice for CredentialsRequest objects to reside in the openshift-cloud-credential-operator namespace for centralized management, while the target Secrets are placed in the specific component namespaces where they are needed (e.g., openshift-image-registry) [1][2]. 2. Namespace Reconciliation: If the namespace specified in spec.secretRef.namespace does not exist when a CredentialsRequest is created, the CCO controller will not fail [1][2]. Instead, the controller tolerates the missing namespace and will reconcile (i.e., create the Secret) immediately once that namespace is created [5][1][2]. 3. Component Expectations: Cluster components are expected to tolerate the temporary absence of the credentials secret (i.e., until the CCO has successfully reconciled the CredentialsRequest and created the secret) [1][2][6]. The reconciliation loop is automatic and continuous, ensuring that secrets are created or updated to reflect the desired state defined in the CredentialsRequest [7][8]. This behavior allows the CCO to effectively manage credentials across different namespaces while maintaining decoupling between the request for credentials and the lifecycle of the target namespace itself [2][8].

Make the CredentialsRequest name unique per operator namespace.
When two deployments use different namespaces, ensureCredentialsRequest finds the same existing request and does not update its spec.secretRef.namespace. The second deployment then reads its own namespace, but CCO maintains the Secret in the first deployment's namespace. Derive the request name from namespace for both Get and Create, and add a test for two namespaces.

Superseded by #84, which carries this commit and builds the STS handling on top of it. Closing so the work has one home. |

The operator called
LoadDefaultConfigand hoped. That works on ROSA, where the pod identity webhook injects a web identity token once the ServiceAccount is annotated, and nowhere else: on an ordinary IPI cluster the chain finds nothing,sts:GetCallerIdentityfails, and theCUDNBgpConfiggoes Degraded withCloudCredentialsInvalidon a cluster where nobody has done anything wrong.ResolveCredentialsnow asks the SDK first and the cluster second. Where the pod already has credentials they are used and the cluster is left alone, so ROSA behaves exactly as it did. Where it has none, the operator creates aCredentialsRequestfor itself carrying the nine EC2 actions it actually uses, and reads the secret the cloud credential operator mints into its own namespace. That is whatexternal-dns-operatordoes, and itse2e-aws-operatorjob on the same CI profile shows that minting works there.Deciding between the two by retrieving from the SDK's own chain, rather than by reading the Infrastructure CR or sniffing
AWS_ROLE_ARN, keeps the decision on the thing that matters.LoadDefaultConfigassembles a chain without consulting it, so only a retrieval answers the question of whether anything is actually there.Minting takes a few seconds, and during them the operator is not broken.
platform.ErrCredentialsPendingsays so, and Phase 3 waits it out the way Phase 2 waits for FRR:Configuring,CloudEndpointsDiscovered=Falsewith reasonWaitingForCloudCredentials, requeue in ten seconds. A secret that exists but carries no usable keys is the opposite case -- the cluster has answered and the answer is no good -- so that is an error, and it names the ServiceAccount to annotate in case the cluster turns out to use STS.The secret permission is a namespaced Role rather than a cluster-wide one, because the operator reads one secret, its own.
POD_NAMESPACEcomes from the downward API, since OLM installs wherever the administrator asks, and the constant covers running the manager from a desk.The first commit is the
.gitignorefix from #84, needed here becausego tool kustomizedoes not build without it and so neither doesmake bundle.Test plan
Five tests written first and confirmed red before the code existed: the ambient chain wins and no
CredentialsRequestis created; a request is created and the result is pending; a minted secret's keys are what the SDK gets; a secret with no usable keys is an error and not pending; a second call does not duplicate the request. Plus a controller test pinning that a pending credential is a ten-second requeue inConfiguringrather thanDegraded.go test ./internal/... ./api/... ./cmd/...passes,make lintreports no issues, andmake bundleregenerates cleanly so the CSV carries the newclusterPermissionsentry, the namespacedpermissionsentry andPOD_NAMESPACE.Not yet exercised on a live cluster: the CCO round trip itself. openshift/release#84073 installs the operator from its bundle onto an IPI AWS cluster, and once that job creates a
CUDNBgpConfigit will cover this path end to end.
