@luolanzone : the plan is to squash all commits and merge?

luolanzone · 2022-01-19T00:54:29Z

@jianjuns I suppose it lose the author information if we squash all commits, maybe I can merge some of them which is owned by me to reduce the total commits, what's your suggestion?

jianjuns · 2022-01-19T03:36:40Z

@luolanzone: as we talked, could you check the commits that impact other Antrea code/functionality, and make sure they do not break anything?

luolanzone · 2022-01-19T04:51:54Z

@jianjuns sure, I will check.

@luolanzone : the plan is to squash all commits and merge?

@jianjuns We could use "create a merge commit" to merge the PR so the branch history will be preserved and there will be only one merge commit in the main branch, and it can be reverted atomically.

jianjuns · 2022-01-20T02:43:50Z

create a merge commit
Will individual commits be counted to different contributors in the github stats?

tnqn · 2022-01-20T02:51:33Z

Will individual commits be counted to different contributors in the github stats?

git tools preserve the contribution correctly. For example, git blame can show the original commit and author that adds the line of code, instead of the merge commit and its author. But I'm not sure how github stats counts the contribution.

tnqn · 2022-01-20T03:27:10Z

@jianjuns I just confirmed antrea.devstats.cncf.io has counted contribution correctly when contributors merged their code to feature branch.

MCS CommonArea and ClusterSetReconciler implementation MCS is a feature that allows resource and policy configuration that span across multiple k8 clusters. A ClusterSet defines such a group of k8 clusters which requires resource exchange. A ClusterSet needs to have one or more clusters chosen as a Leader which facilitates the resource exchange so that we dont need a full-mesh between all clusters in the ClusterSet. Leader can be dedicated which means they dont participate in the resource exchange themselves. Or they call be both a leader and member, so it facilitates and also takes part in the resource exchange. Members of the ClusterSet write certain resources into leader cluster’s common area and all members pull resources from that common area. Common area refers to the namespace within a leader cluster where the leader controller is running and where resources are written and read from. MCS Controller needs to be run in a leader/member mode. Because the operations performed on leader/member are different two sub-commands (leader, member) are provided to specify which mode the controller is running in. Validations for ClusterSet configuration ---------------------------------------- Following validations are performed by the ClusterSetReconciler 1. There must be a valid ClusterClaim with ClusterID and ClusterSetID 2. The configured ClusterID is defined as either a member/leader in the ClusterSet 3. Only one ClusterSet configuration is allowed MemberClusterSetReconciler ------------------------------ MemberClusterSetReconciler runs only in member cluster deployment. It will initialize RemoteCommonAreaManager to manage connections to all Leader’s common area which will be represented as RemoteCommonArea. Once a connection is established two things occur: 1. A MemberClusterAnnounce resource is written to all RemoteCommonArea periodically. 2. A leader election is performed to choose an elected leader among all configured leaders. An elected leader is the leader cluster from where resources will be imported for the resource exchange pipeline. LeaderClusterSetReconciler ----------------------------- LeaderClusterSetReconciler runs only in leader cluster deployment and mainly performs the validations. ClusterSet status: ------------------ Status of the ClusterSet resource is not implemented in this patch and will come in a future patch. MCS Manifests --------------- There are 3 manifests that are generated: 1. Leader global - this contains all the global resources that needs to be applied once on the leader cluster. 2. Leader namespaced - the leader MCS controller runs within the context of a namespace. Namespaced yaml must be generated for the required Namespace and applied on the leader cluster. The provided yaml uses `changeme` as the Namespace for all resources and must be changed to the correct Namespace required. Or a new yaml can also be generated using $ antrea/multicluster/hack/generate-manifest.sh -l <namespace> 3. Member - this is the manifest that needs to be applied on the member cluster. Key differences in Member and Leader Namespaced yamls: Controller: ---------- A member runs only one MCS controller which reconciles resources across all namespaces in the cluster. A leader runs one MCS controller in a given Namespace which reconciles resources only within that Namespace. RBAC is configured to provide entire cluster access to the member controller and for the given Namespace for the leader controller. Webhooks: ----------- Webhooks are configured globally in the member deployment. Webhooks are configured within a Namespace in the leader Deployment. So in leader cluster which has multiple MCS Deployments, there will be multiple webhooks each redirecting requests within a given Namespace to the corresponding controller. This was a conscious choice to avoid a hierarchical controller. Also webhooks will be performing Namespace specific validations so they cannot be handled by a global service. A cluster that is both a leader and member: ------------------------------------------- A cluster can be both a leader and member, in this case, there will be two controllers running - one member controller and second leader controller within a Namespace. TODO: We need special handling so member controller does not reconcile resources within leader Namespace even though it has cluster-wide access. Unit testing: ========= RemoteCommonArea Tests --------------------------- Test that MemberClusterAnnounce is written and connectivity is set to true. TODO: Find out if fakeClient can error writes so we can test disconnection case NOTE: used mockgen to generate mocks for Manager from controller-runtime library and for RemoteCommonAreaManager. TODO: Add mockgen to Makefile so it always gets generated automatically. RemoteCommonAreaManager and LeaderElector tests ------------------------------------------------------- 1. Test adding a new leader cluster 2. Test leader election 3. Test leader election when elected leader becomes disconnected TODO: Test removing a leader cluster NOTE: Used mockgen to generate a mock for RemoteCluster so that we can verify StartMonitoring is invoked. TODO: Add mockgen to Makefile so it always gets generated automatically. Signed-off-by: aravindakidambi <[email protected]>

…3111) MCS: MemberClusterAnnounce webhook and CluterSet.Status implementation MemberClusterAnnounce webhook ----------------------------------- Implement a custom webhook to authenticate the request to write MemberClusterAnnouce. The webhook will get ClusterID from MemberClusterAnnounce and get the ServiceAccount associated with that member cluster from ClusterSet configuration and ensure the incoming request has been authenticated with the same ServiceAccount. This prevents a member spoofing the ClusterID when writing MemberClusterAnnounce. NOTE: Removed the default webhook from kube-builder because it does not provide access to the user-info of the request. ClusterSet.Status computation on leader clusters -------------------------------------------------- MemberClusterAnnounceReconciler will run an interval timer which monitors MemberClusterAnnounce resources to compute status as follows: 1. All configured members will start with: a. "Ready" = "Unknown" b. "ImportsResources" = "False" 2. The timer determines the following: a. If there is atleast one update of MemberClusterAnnounce resource from a member in a consecutive 3 timer intervals, the status of member will be "Ready" = "True" b. If "Ready" = "True", based on the last MemberClusterAnnounce received from that member: i. "ImportsResources" = "True" if the local leader cluster is the elected leader for member. Message will be "Local cluster is the elected leader of member <cluster-id>" and reason says "ElectedLeader" ii. "ImportsResources" = "False" if some other leader was elected by this member. Message will be "Local cluster is not the elected leader of member <cluster-id>" and reason will be "NotElectedLeader" iii. "ImportsResources" = "Unknown", if no leader has been elected yet by this member. Message will be "Leader has not been elected yet" c. If there is no update in a consecutive 3 timer interval, then the member is marked "Ready" = "False" and "ImportsResources" = "False". Message will state - "No MemberClusterAnnounce update after <timestamp>" and Reason will be "Disconnected". LeaderClusterSetReconciler will have a goroutine that runs periodically to update the ClusterSet.Status, as follows: 1. TotalClusters is the number of clusters in the ClusterSet resource last processed. 2. ObservedGeneration is the Generation in the ClusterSet resource last processed. 3. Individual cluster status is obtained from MemberClusterAnnounceReconciler. 4. ReadyClusters is the number of clusters with "Ready" = "True". 5. Overall condition of the ClusterSet is also computed as follows: a. "Ready" = "True" if all clusters have "Ready" = "True". Message & Reason will be absent. b. "Ready" = "Unknown" if all clusters have "Ready" = "Unknown". Message will be "All clusters have an unknown status" and Reason will be "NoReadyCluster". c. "Ready" = "False" for any other combination of cluster statues across all clusters. Message will be empty and Reason will be "NoReadyCluster". Note: Other leaders and local leader cluster will not be present in the status. Because its status is not meaningful and can skew the overall status. ClusterSet.Status computation on member clusters -------------------------------------------------- RemoteCommonAreaManager will support getting status of all leaders from individual RemoteCommonArea. RemoteCommonArea provides status as follows: 1. When configured, leader start with: a. "Ready" = "Unknown" b. "IsElectedLeader" = "False" 2. Update "Ready" = "True"/"False" based on connectivity to RemoteCommonArea. Message will contain error if member has any error with connectivity. Reason will be "Disconnected" in error cases. 3. There will be an additional status for "IsElectedLeader" and this will be "True" if leader election has finished and has elected this leader, "False" if some other leader was elected, "Unknown" if leader election is incomplete. a. Message will be "This leader cluster is/is not an elected leader for local cluster". b. If leader election is incomplete, Reason = "LeaderElectionInProgress". MemberClusterSetReconciler will have a goroutine that runs periodically to update the status, as follows: 1. TotalClusters is updated based on number of clusters in the last processed config. 2. ObservedGeneration is from Generation of the last processed config. 3. Individual cluster status is obtained from RemoteCommonAreaManager. 4. ReadyClusters is computed based on number of cluster with "Ready" = "True". 5. Overall condition of the ClusterSet is computed as follows: a. "Ready" = "True" if it is connected to atleast one leader and elected it as a leader. b. "Ready" = "False" if it is disconnected from all leaders. c. "Ready" = "Unknown" otherwise. Message will be "Leader not elected yet". Signed-off-by: aravindakidambi <[email protected]>

1. exporter serviceexport_controller is responsible to reconcile ServiceExport resource in member cluster and write wrapped ResourceExport into leader cluster, meanwhile it will watch Service and Endpoints change via event mapping and update ResourceExport when exported Service/Endpoints are updated. resourceexport_controller is responsible to reconcile ResourceExport resources and computes all ResourceExports from different member clusters into one ResourceExport in leader cluster if the resources are exported with the same namespaced name and the same kind, for this moment, we only support Service, Endpoints kind. 2. importer remote_resourceimport_controller watches leader cluster's ResourceImport events and create corresponding ServiceImport, Service and Endpoints with AntreaMCServiceAnnotation in member cluster. ServiceImport name will be the same as exported Service, new created Service and Endpoints will have an antrea multicluster prefix. 3. stale controller stale controller is mainly for special cases when resource is deleted during controller restarting in leader or member cluster, it will be triggered once only when controller starts. Notes: serviceexport_controller, stale_controller and resourceimport_controller will run only in member cluster, resourceexport_controller will run only in leader cluster.
