Now the best route is used rather than always using the default gateway. Any workload-initiated outbound call is routed to the private IP address of the Azure Firewall by the default user-defined route with, Gets the AKS cluster credentials using the. This update puts a limit on header size for the oc adm catalog mirror command, allowing mirroring to work as expected. Access to the extension can reuse the authorization used by the core API server; for example, RBAC. OpenShift Container Platform 4.11 introduces heterogeneous architecture cluster support using Azure installer-provisioned infrastructure in Technology Preview. The scope of access to cluster DNS records. You can now define an existing Route 53 private hosted zone for your cluster by setting the platform.aws.hostedZone field in the install-config.yaml file. Therefore, for user-defined projects, if you queried external metrics not provided by the user workload monitoring instance of Prometheus, you would sometimes not see external labels for these metrics even though you had configured Prometheus to add them. Installing an Aggregated API server always involves running a new Deployment. After performing The following error message is displayed: timed out waiting for OVS port binding. By default, the pruner runs once a day. For more information, see Installing the OpenShift CLI. In this task, you learned how to monitor access to external services and set a timeout (BZ#2054285), Before this update, the empty tabs in the sidebar of the topology view were not filtered out before rendering. However, with assisted installers this information was not provided. Machine sets can create compute machines that allow the use of both IMDSv1 and IMDSv2 or compute machines that require the use of IMDSv2. The tool consumes must-gather data from the cluster and several user-supplied profile arguments, and using this information it generates a performance profile that is appropriate for your hardware and topology. The SHA-256 image digest information in the RHBA-2021:3247 advisory is incorrect. (BZ#1975708). The following new features are supported on IBM Power Systems with OpenShift Container Platform 4.8: The following features are also supported on IBM Power Systems: Note the following restrictions for OpenShift Container Platform on IBM Power Systems: OpenShift Container Platform for IBM Power Systems does not include the following Technology Preview features: Persistent storage must be of the Filesystem type that uses local volumes, Network File System (NFS), or Container Storage Interface (CSI). We want to make sure you're aware For more information on cron jobs, see Understanding jobs and cron jobs. Red Hat is committed to replacing problematic language in our code, documentation, and web properties. Some users pulling images from Docker Hub can encounter the following error: This error happens because the docker.io login they used to call the oc new-app does not have sufficient paid support with docker.io. Open Virtual Network (OVN) was redesigned to host its control plane and data store alongside the clusters control plane. Make sure to specify values for the variables in the cd-self-hosted-agent and in the agent.tfvars. # # Provide a name in place of kube-prometheus-stack for `app:` labels nameOverride: " " # # Override the deployment namespace namespaceOverride: " " # # Provide a k8s version to auto dashboard import script example: For clusters with the credentials mode set to its default value of "", the updated CCO automatically changes from operating in mint mode to operating in passthrough mode. For more information, see Requesting CRI-O and Kubelet profiling data using the Node Observability Operator. without controlling access to external services. (BZ#1955467), Previously, an incorrect keepalived setting sometimes resulted in the VIP ending up on an incorrect system and unable to move back to the correct system. The bug fixes that are included in the update are listed in the RHBA-2022:6511 advisory. You can now specify an individual repository within a registry when creating lists of allowed and blocked registries for pulling and pushing images. For clusters on user-provisioned bare metal infrastructure, the OVN-Kubernetes cluster network provider supports both IPv4 and IPv6 address families. With this update, the updated APIs for the Kafka CR support the old versions and renders the Bootstrap server list in Create Event Source - KafkaSource form. In this update, the pip version is fixed to a value less than 21 to avoid the problem. With this fix, the installation program is now updated to an upstream Terraform provider, which ensures eventual consistency. In this example, you set a timeout rule on calls to the httpbin.org service. (BZ#2025396), Previously, the SystemMemoryExceedsReservation alert using Prometheus QL was using hugepages memory consumption. Whether to masquerade traffic to the link-local prefix (169.254.0.0/16). This fix increases the limit to 2G so that qemu-img now completes provisioning reliably. With this enhancement, users can select a policy in the MachineSet resource to populate settings automatically. The current release increases the number of retries to these interactions. In OpenShift Container Platform 4.11, the Insights Operator collects the following additional information: The images.config.openshift.io resource definition, kube-controller-manager container logs when the "Internal error occurred: error resolving resource" or "syncing garbage collector with updated resources from discovery" error messages are present, storageclusters.ocs.openshift.io/v1 resources. This update specifies the correct API version in all owner references. (BZ#1972258), Previously, the load balancer service became unstable when users would scale additional Windows nodes. (BZ#1928157), Previously, when using the OVN-Kubernetes cluster network provider, the endpoint slice controller might not run if the Kubernetes version included a minor version that contained non-numeric characters. (BZ#1942271), Previously, DNSmasq required specifying the prefix length when an IPv6 network was anything other than /64. OpenShift Container Platform 4.11 on Azure provides accelerated networking for control plane and compute nodes. Are types enforced (in other words, don't put an, The new endpoints support CRUD basic operations via HTTP and, The new endpoints support Kubernetes Watch operations via HTTP, Access to the extension uses the core API server (aggregation layer) for authentication. These features are available only for OpenShift Container Platform on IBM Z for 4.8: HyperPAV enabled on IBM Z /LinuxONE for the virtual machines for FICON attached ECKD storage. For more information, see Using the Node Maintenance Operator to place nodes in maintenance mode. For example: Use --set values.global.proxy.includeIPRanges="10.4.0.0/14\,10.7.240.0/20", Use --set values.global.proxy.includeIPRanges="10.244.0.0/16\,10.240.0.0/16. As a result, decorators were shown for associated revisions of Knative service in Topology. Now, builds check if an error has occurred, and only log the Successfully pushed message after an image push has succeeded. For more information, refer to About network policy. For more information, see Configuring PROXY protocol for an Ingress Controller. You can now set the maximum number of simultaneous connections that can be established per HAProxy process in the Ingress Controller to any value between 2000 and 2,000,000. The next minor release of OpenShift Container Platform is expected to use Kubernetes 1.25. Both the public IP and public IP configuration are dedicated to this workload. As a result, pipelines for private Git repositories run successfully. OpenShift Container Platform is now available on the Azure Marketplace. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. The Customer Managed Encryption Key used to encrypt the boot disk attached to each node in the node pool. Send an HTTPS request to access the httpbin service through HTTPS: The httpbin service will return the For more information, see Pod preemption and other scheduler settings. Configure Istio ingress gateway to act as a proxy for external services. Now network connectivity survives a restart of the NetworkManager service. The ignore_changes argument is used to instruct Terraform to ignore updates to given resource properties such as tags. Kubernetes client libraries can be used to access custom resources. (BZ#1948047), Previously, a reboot request to a container or image could cause failure if the reboot occurred while the container or image was being committed to the disk. This behavior is similar to passthrough mode. Consequently, Operator resources were not properly deleted. All OpenShift Container Platform 4.8 errata is available on the Red Hat Customer Portal. Alternatively, pod disruption budgets can be created from pod controller resources list and Detail pages. This patch updates the Provider Type filter to Source. used for internal cluster services. Previously, you could not specify the subdomain of a route, and the spec.host field was required to set the host name. Because of this, all subscriptions were blocked. Previously, operators had to delete and recreate the IngressController to enable PROXY protocol for clusters updated to 4.8. This can happen when routers in the terminating state delay the oc cp command. The Operator no longer prints excessive update events in the logs. With this fix, Shared Resource CSI Driver metrics are exposed to the Telemetry service. (BZ#2069457), The Ingress Operator performs health checks against the ingress canary route. To evict pods instead of simulating the evictions, change the descheduler mode to automatic. With this release, the CCO no longer reports if its deployment is unhealthy. (BZ#2076297), Previously, when an Ingress Controller for an admitted route was deleted or a sharding configuration was added, a false status of admitted was given. Later releases revoked this access to reduce the possible attack surface for security exploits because some discovery endpoints are forwarded to aggregated API servers. With this fix, reducing the warning level to baseline resolves the issue. With this update, Linux hugepages have been removed from the system memory circulation, and the alert no longer unnecessarily triggers. Every ipBlock after the first one was ignored, resulting in pods being unable to reach all of the configured IP addresses. With this update, the Ingress Operator status more accurately reflects the status of the canary controller. Support for using Red Hat Enterprise Linux (RHEL) 7 with the OpenShift CLI (oc) has been removed. (BZ#1929944), Previously, the readiness probe was not reporting the correct readiness due to the introduction of SO_REUSEADDR socket options, which caused the etcd pod to show as ready even though the etcd-quorum-guard failed. The resources/services/activations/deletions that this module will create/trigger are: Sub modules are provided for creating private clusters, beta private clusters, and beta public clusters as well. Previously, only the KILL, MKNOD, SETUID, and SETGID capabilities were dropped. This could lead to Terraform being unable to determine the correct network to use. With this fix, zipl now takes the disk sector size into account so that zVM boots successfully. Consequently, control plane hosts failed to PXE boot. You can review the descheduler metrics to view details about pods that would be evicted. you can configure the Envoy sidecars to prevent them from The commands below use As a result, new machines can now boot with the default GCP image. pstate scaling_governor: When the Intel pstate driver status is active, the pstate scaling_governor label reflects the scaling governor algorithm. As a result, UDP DNS messages are now properly received. You can use the Poison Pill Operator to allow unhealthy nodes to reboot automatically. For more information, see Reducing power consumption by taking CPUs offline. The Node Tuning Operator is part of the standard installation for OpenShift Container Platform 4.11. Consequently, the mapi_current_pending_csr was stuck at 1 until another machine approver reconciled it. Packets going to the firewall's public IP address are routed via the Internet. (BZ#1906056), Because k8s.io/apiserver was not handling context errors for the webhook authorizer, context errors, such as timeouts, caused the authorizer to panic. With this release, the displayed time is reformatted so that UTC is readable and understandable. Now, there is a 60 percent reduction in run time when parsing and evaluating the haproxy-config.template. Previously, during a cluster upgrade, the /etc/hostname file was altered by CRI-O, which caused the nodes to fail and to return when rebooting. To view the pipeline parameter, and the correct syntax for referencing that particular pipeline parameter, go to the respective text fields. For more information, see Upgrading your heterogeneous cluster. OpenShift Container Platform 4.11 introduces the Self Node Remediation Operator that replaces the Poison Pill Operator. You can now define an already existing resource group to install your cluster to on Azure by defining the platform.azure.resourceGroupName field in the install-config.yaml file. If you have any Operator projects that were previously created or maintained with Operator SDK v1.3.0, see Upgrading projects for newer Operator SDK versions to ensure your projects are upgraded to maintain compatibility with Operator SDK v1.8.0. The bug fixes that are included in the update are listed in the RHBA-2021:3682 advisory. See the OpenShift Container Platform Life Cycle for more information about asynchronous errata. kubectl, just as they do for built-in resources Administrators who created credentials requests in manual mode with the Cloud Creditial Operator (CCO) will need to apply those changes manually if they intend to mount encrypted volumes using customer managed keys on AWS. The node-exporter agent is now on version 1.1.2. kube-state-metrics is upgraded to version 2.0.0. OpenShift Container Platform release 4.8.4 is now available. Consequently, some resources created by the OpenShift Container Platform installation program are placed in the default resource group. (BZ#1952914), Previously, when users created a Windows pod with a projected volume, the pod would remain stuck in the ContainerCreating phase. Deleting Files at the Destination. Install Multi-Primary on different networks, Install Primary-Remote on different networks, Install Istio with an External Control Plane, Customizing the installation configuration, Custom CA Integration using Kubernetes CSR *, Istio Workload Minimum TLS Version Configuration, Classifying Metrics Based on Request or Response, Configure tracing using MeshConfig and Pod annotations *, Learn Microservices using Kubernetes and Istio, Wait on Resource Status for Applied Configuration, Monitoring Multicluster Istio with Prometheus, Understand your Mesh with Istioctl Describe, Diagnose your Configuration with Istioctl Analyze, ConflictingMeshGatewayVirtualServiceHosts, EnvoyFilterUsesRelativeOperationWithProxyVersion, EnvoyFilterUsesRemoveOperationIncorrectly, EnvoyFilterUsesReplaceOperationIncorrectly, NoServerCertificateVerificationDestinationLevel, VirtualServiceDestinationPortSelectorRequired, Generate client and server certificates and keys, Configure a TLS ingress gateway for a single host, Configure a TLS ingress gateway for multiple hosts. (BZ#1926984), Previously, the mountstats collector for the node-exporter daemontset caused high memory usage on nodes with NFS mount points. When updating, the Machine Config Operator (MCO) now reports an Upgradeable=False condition in the machine-config Cluster Operator if any machine config pool has not completed updating. With this fix, the pod ID is included in the key that the kubelet uses to manage registered pods. To clean up resources manually, you must find and delete the affected resources. Istio features on traffic to external services. (BZ#1972987). Pod security admission runs globally with privileged enforcement and restricted audit logging and API warnings. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
