Basic identity allocator will be used by operator to manage global identities CID and agent to manage locally created identities that do not require complex features like `pkg/allocator/allocator.go`. Related: cilium#30356 Signed-off-by: Ovidiu Tirla <otirla@google.com>
The field will be used mainly by operator managing CIDs. Related cilium#27752 Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add EnqueueTimeTracker and CIDDeletionTracker structures to manage enqueuing times and track CID deletion marks. Related cilium#27752 Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add indexer for CiliumIdentity objects based on security labels to enable efficient lookup of existing CIDs for reuse during allocation when Cilium Operator manages Cilium Identities. Related cilium#27752 Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add helper function HasCEWithIdentity to check if CiliumEndpoint store contains an endpoint with a given identity. Signed-off-by: Ovidiu Tirla <otirla@google.com>
The Namespace resource will be used by Operator Managing CIDs to fetch relevant labels to create CIDs. Related cilium#27752 Signed-off-by: Ovidiu Tirla <otirla@google.com>
The Pod resource will be used by Operator Manaing CIDs to reconcile all the pods in a namespace when the namespace labels are added or removed. Related cilium#27752 Signed-off-by: Ovidiu Tirla <otirla@google.com>
EnableOperatorManageCIDs enables operator to manage CID by running a CID controller. If enabled, Identity GC cell is then disabled because CID controller takes care of garbage collection. Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add the CID cell for operator with a standard empty controller Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add the reconciler logic for reconciling CIDs, Pods, Namespaces. Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add the pod event listener and handler to enqueue pod reconciliation Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add the namespace event listener and handler to reconcile namespace Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add the CID event listener and handler to reconcile CID Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add the CES event listener and handler to reconcile CID Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add the controller for handling the Operator managing CIDs. The Cilium Identity (CID) controller running in cilium-operator and is responsible only for managing CID API objects. * Pod events are added to Pod work queue * Namespace events are processed immediately and added to Pod work queue * CID events are added to CID work queue * Processing Pod work queue items are adding items to CID work queue * Processed CID work queue items result in mutations to CID API objects Signed-off-by: Ovidiu Tirla <otirla@google.com>
Add metrics for the Operator managing CIDs. Add cid_controller_work_queue_event_count which counts processed events by CID controller work queues labeled by outcome Add cid_controller_work_queue_latency which meters the duration of CID controller work queues enqueuing and processing latencies in seconds Signed-off-by: Ovidiu Tirla <otirla@google.com>
Initialize the labels filter to limit identity-relevant labels Signed-off-by: Ovidiu Tirla <otirla@google.com>
