You are using the resource within your company, or as part of a small open-source project (as opposed to a commercial product). For more information, see Using bound service account tokens. Enforce rate limits. This enables you to have the latest fixes, features, and enhancements, as well as the latest hardware support and driver updates. More information can be found in the following changelog: 1.21.6. This update fixes the issue. Restricted enforcement for such namespaces is planned for inclusion in a future release. (BZ#2021041), Previously, installation methods for VMware vSphere included validation that checked for network existence during the creation of configuration files. This sample shows how to create a private AKS cluster using Terraform and Azure DevOps in a hub and spoke network topology with Azure Firewall. Under certain security profiles, administrators can force Azure to not accept the creation of v1 Storage Accounts. (BZ#1957991), Previously, when users ran a compliance check, NON-COMPLIANT results were given with no indication of required remediation steps for the user to act upon. With this update, scaffolding a Hybrid Helm Operator uses downstream images. OpenShift Container Platform release 4.8.10 is now available. OpenShift Container Platform 4.8 supports three additional labels for the NFD Operator. This update fixes the problem. Any workload-initiated outbound call is routed to the private IP address of the user-defined route. secrets name. The Poison Pill Operator works with all cluster and hardware types. (BZ#1934021), Previously, multiple client sets created inside of the MachineSet controller caused slow startup times, which resulted in pods failing readiness checks in some large clusters. Describes how to configure SNI passthrough for an ingress gateway. (BZ#2061447) For more information, see Persistent storage using local volumes. If you want to pin the ZTP container to a specific version within the release, the patch file argocd-openshift-gitops-patch.json should be updated to point to the specific version. (BZ#1916593), Previously, e2e-gcp-upi did not succeed because of a Python package error which resulted in a failure. 4K FCP block device. (BZ#1966077), Previously, tables displayed incorrectly on mobile devices. With this update, the machine instance state annotation is now set, and information in the STATE column automatically populates. In OpenShift Container Platform 4.8, installer-provisioned clusters can configure and deploy Network Time Protocol (NTP) servers on the control plane nodes and NTP clients on worker nodes. With this update, the Ingress Controller clears the status of an unadmitted route, avoiding the false status scenario. Disabling RAID for all drivers. (BZ#2097153), Because the kubelet needs to contact the vCenter to obtain node zone labels, if the vCenter credentials are stored in a secret, the kubelet could not start because the kube client was not created on time. It describes the two The components initualize successfully, and LoadBalancer-type services are able to be created. This release includes critical security updates for CVE-2021-44228, CVE-2021-45046, CVE-2021-4104, and CVE-2021-4125, all of which concern the Apache Log4j utility. (BZ#1857008), Because newer ipmitool packages default to using cipher suite 17, older hardware that does not support cipher suite 17 fails during deployment. Versioned asynchronous releases, for example with the form OpenShift Container Platform 4.8.z, will be detailed in subsections. Consequently, some clusters in the Machine API Operator would time out because of unexpected API server outages. Common metadata across objects that tools know how to edit for core and custom resources. The ci-test-web-app pipeline performs the following steps: The cd-test-web-app pipeline performs the following steps: In a production environment, the endpoints publicly exposed by Kubernetes services running in a private AKS cluster should be exposed using an ingress controller such as NGINX Ingress Controller or Application Gateway Ingress Controller that provides advanced functionalities such as path based routing, load balancing, SSL termination, and web access firewall. With this release, the oc rsync command displays the correct error message when the specific container is not running. With this update, an additional OVS rule is inserted to notice when port conflicts occur and to do an extra SNAT to avoid said conflicts. Pipelines are part of the same Git repo that contains the artifacts such as Terraform modules and scripts and as such pipelines can be versioned as any other file in the Git reppsitory. (BZ#2048575), With this update, OpenShift Container Platform clusters with Kubernetes-NMstate installed now include in the` must-gathers` Kubernetes-NMstate resources. (BZ#1725981), Previously, the oc image extract command did not extract files from the root directory of an image. (BZ#1999325), Because of a memory leak in the garbage collection process, pods might not be able to start on a node due to lack of memory. Currently, the prerequisites in the web console quick start cards appear as a paragraph instead of a list. (BZ#1920532), Previously, when starting a single-stack IPv6 cluster on nodes with IPv4 address, the kubelet might have used the IPv4 IP instead of the IPv6 IP for the node IP. See BZ#1957708 for more information. When creating subscriptions with a new CatalogSource, the CatalogSource remains in a TRANSIENT_FAILURE state. This update contains changes from Kubernetes 1.21.6 up to 1.21.8. This error is now ignored if a pod is terminating. For more information, see Mirroring images for a disconnected installation using the oc-mirror plug-in. The Query Browser on the Observe Metrics page of the OpenShift Container Platform web console adds various enhancements to improve your ability to create, browse, and manage PromQL queries. The RPM packages that are included in the update are provided by the RHBA-2022:0020 advisory. With scalability in mind, the prerequisites are now presented in a popover rather than on the card. Use the operator.openshift.io/v1 API group instead. Red Hat Virtualization (RHV) will be deprecated in an upcoming release of OpenShift Container Platform. As a result, the output from that command does not include the message. (BZ#1925245), Previously, exposing the default Ingress Controller through an external load balancer that redirected all HTTP traffic to HTTPS caused Ingress Canary endpoint checks performed by the Ingress Operator to fail, which would ultimately cause the Ingress Operator to become degraded. The RPM packages that are included in the update are provided by the RHSA-2021:3248 advisory. With this update, the machine boots with DHCP enabled on all interfaces even if the BOOTIF argument is provided. or As a result, these messages are no longer being produced. (BZ#1947490), Previously, systemd was excessively reading mountinfo and over-consuming CPU resources, which caused containers to fail to start. This enables you to have the latest fixes, features, and enhancements, as well as the latest hardware support and driver updates. With this update, the misplaced recycler-pod template has been removed from the static pod manifest directory. As a result, the Reporting Operator correctly handles events for expired Report CRs. This provides the Cluster Operator with more realistic and useful alerts without prematurely degrading performance of a normal cluster. Now, the openshift-install command is revised so that it produces an error like the following message: Previously, the installation on Red Hat OpenStack Platform (RHOSP) failed unless the RHOSP HTTPS certificate was imported to the hosting device. which may cause some requests to fail. (BZ#1924788), Previously, when you tried to create a virtual machine from a Red Hat Enterprise Linux (RHEL) 6 template in the web console, a pop-up window gave information about how to define the support level, even through RHEL 6 is not supported. The ranges are not fixed, so you will need to run the gcloud container clusters describe command to determine the As a result, the topology view did not display service binding connectors. # This is a YAML-formatted file. (BZ#1896321), Previously, pod disruption budgets did not drain pods on an unreachable node due to missing upstream eviction API features. 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. If enabled, a daemonset will be created in the cluster to meter network egress traffic. This command commits 53 CRDs to the kube-apiserver, making them available for use in the Istio mesh.It also creates a namespace for the Istio objects called istio-system and uses the --name option to name the Helm release istio-init.A release in Helm You can deploy a single Windows or Linux Azure DevOps agent using a virtual machine, or use a virtual machine scale set (VMSS). Consequently, if a security context constraint (SCC) existed that enforced readOnlyRootFileSystem: true and matched the securityContext of the that pod, it would be assigned to that pod and cause it to fail repeatedly. OpenShift Container Platform 4.11 removes "OpenShift Jenkins Maven" and "NodeJS Agent" images from its payload. As a result, the hosts succeed on DHCP and PXE boot on IPv6 networks of any prefix length. Consequently, Operator resources were not properly deleted. In this case: Generate individual TLS certificates by using a different CA. Operator pattern combines custom With this fix memory is no longer leaking in the garbage collection process and nodes should start as expected. KVM on RHEL 8.3 or later is supported as a hypervisor for user-provisioned installation of OpenShift Container Platform 4.8 on IBM Z and LinuxONE. OpenShift Container Platform clusters on Red Hat OpenStack Platform (RHOSP) now support provider networks for all deployment types. (BZ#2024690), The oc-mirror CLI plug-in cannot mirror OpenShift Container Platform catalogs earlier than version 4.9. (OCPBUGSM-97), If an SNO cluster is upgraded from OCP 4.10 to OCP 4.11, the SNO cluster might get rebooted three times during the upgrade process. When you combine a custom resource with a custom controller, custom resources This release introduces the following customizations for the descheduler: Priority threshold filtering: Set the priority threshold either by class name (thresholdPriorityClassName) or by numeric value (thresholdPriority) to not evict pods that have a priority that is equal to or greater than that value. You do not need to understand API Aggregation to use CRDs. (BZ#2047670), Previously, there was an eventual consistency issue in the AWS Terraform provider when updating to newly created Virtual Private Clouds (VPCs). With DNS resolution, the sidecar proxy will ignore the original destination IP address and direct the traffic (BZ#2108700), There is a known issue with Nutanix installation where the installation fails if you use 4096-bit certificates with Prism Central 2022.x. See BZ#1924869 for more information. When using kernel-rt, the slower creation times impact the maximum number of supported pods because recovery time is impacted after a node reboots. (BZ#1931467), Previously, the maximum transmission unit (MTU) specification for a bond interface using kernal arguments did not get assigned properly. With this update, the DNS operator was changed to add the cluster-autoscaler.kubernetes.io/enable-ds-eviction annotation to DNS pods. allowPrivilegeEscalation must be unset or set to false in security contexts. Now, CRI-O recalls CNI DEL requests until they succeed, correctly cleaning up CNI resources. (BZ#2090151), Previously, when you tried to delete multiple clusters from the database in parallel, the deletion process failed because of a bug in the vmware and govmomi libraries. Currently, it is not supported to use Microsoft identity platform when group names are required to be synced. (BZ#2037721), Previously, a race condition in the NetworkManager restart sometimes prevented DHCP resolution to successfully complete setting up the br-ex bridge on node boot when using OVN-Kubernetes. The Jobs Completions column now sorts on the # Succeeded for better understanding. This update contains changes from Kubernetes 1.21.9 up to 1.21.11. In addition, releases in which the errata text cannot fit in the space provided by the advisory will be detailed in subsections that follow. With this update, tables now display correctly. As an Operator author, you can run the bundle validate command in the Operator SDK to validate the content and format of an Operator bundle. This was due to an issue with the Form or YAML switcher for pages such as Pipeline Builder and Edit HorizontalPodAutoscaler (HPA). Red Hat recommends that you use virtual hardware version 15 or later. OpenShift Container Platform release 4.8.48 is now available. Bound service account tokens are audience-bound and time-bound. As a result, the assignment of IP addresses to egress nodes is now successfully permitted. For more information, see BZ#1874322. (BZ#1944268), Previously, on-premise platforms lacked the capability to create internal load balancers. Update your istio-sidecar-injector configuration map using the IP ranges specific to your platform. This update cleans up CNI resources and allows a successful reboot. With this update, CronJob launched on Whereabouts IPAM CNI use the api-internal server address and an extended api timeout to prevent these connectivity issues. In the table, features are marked with the following statuses: Package manifest format (Operator Framework), --filter-by-os flag for oc adm catalog mirror, ImageChangesInProgress condition for Cluster Samples Operator, MigrationInProgress condition for Cluster Samples Operator, Use of v1 in apiVersion for OpenShift Container Platform resources, Use of dhclient in Red Hat Enterprise Linux CoreOS (RHCOS), lastTriggeredImageID field in the BuildConfig spec for Builds, HPA custom metrics adapter based on Prometheus, The instance_type_id installation configuration parameter for Red Hat Virtualization (RHV), Minting credentials for Microsoft Azure clusters. Starting with OpenShift Container Platform 4.6, OAuth access token and authorize token object names are stored as non-sensitive object names, with a SHA-256 prefix. This feature applies only to the DNS Operator and not the CoreDNS instance managed by the Machine Config Operator. (BZ#1921727), Previously, custom security context constraints (SCCs) could have a higher priority than others in a default set. To update an existing OpenShift Container Platform 4.8 cluster to this latest release, see Updating a cluster within a minor version by using the CLI for instructions. With this enhancement, the Catalog Operator now retries errors during install plan execution for up to one minute. There is an existing, well-documented configuration file format, such as a. Now, the installer process can communicate with the virtual IP for the API server. For more information, see Dynamic plug-ins. (BZ#2053622), Before this update, invalid subscription labels were created when a resource name exceeded 63 characters. (BZ#2061676), Previously, the Ingress Operator did not validate whether a Kubernetes service object in the OpenShift Ingress namespace was created or owned by the Ingress Controller it was trying to reconcile with. This is currently a Technology Preview feature. (BZ#1949361), Previously, there was a transport leak in the etcd Operator, which caused memory usage to grow over time. The application code is available under the source folder, while the Helm chart is available in the chart folder. See Kubernetes API removals to read more about Kubernetes' policy on removing APIs. This update fixes the issue by collecting information about the cloud before it checks for quota and then reuses the same information for validations. OpenShift Container Platform 4.11 is supported on Red Hat Enterprise Linux (RHEL) 8.4 and 8.5, as well as on Red Hat Enterprise Linux CoreOS (RHCOS) 4.11. used for internal cluster services. Choosing a method for adding custom resources, Third party code and new points of failure, Authentication, authorization, and auditing, You want your new types to be readable and writable using. If this happens, temporarily change the seLinuxOptions strategy in the sandboxed-containers-operator-scc SCC to the less restrictive RunAsAny, so that the admission process does not prefer it over the hostmount-anyuid SCC. To align with upstream Kubernetes having moved the LegacyServiceAccountTokenNoAutoGeneration feature gate to beta and enabling it by default, OpenShift Container Platform now also follows this security feature and releases with the feature enabled. No need to handle multiple versions of your API; for example, when you control the client for this resource, you can upgrade it in sync with the API. The Security Configuration Guide intends to be a reference. Previously, ovnkube-node and ovnkube-master pods failed to start when the config file had an unknown field or section. This caused the installation to fail. Now, a successful installation occurs when the cacert value in cloud.yaml is set to the RHOSP HTTPS certificate. Application-layer Secrets Encryption settings. If a cluster is incrementally updated from a version less than or equal to 4.9, the openshift-dns namespace may not contain the required pod-security labels required for future version updates. (BZ#1976241). With this update, the GCP image is updated to match the release version. (BZ#2006698). Updating the Bare Metal Operator to align the iRMC PowerInterface. Red Hat recommends that you use ESXi 7.0 Update 2 or later. The NET_BIND_SERVICE capability can now be added explicitly. With this release, the bug fix summary for BZ#1960446 is moved to the "Bug fixes" section of the OpenShift Container Platform 4.8.4 release notes, and the bug fix summary for BZ#1954309 is removed. PVs are now enqueued correctly so that they delete properly. When errata notifications are enabled, users are notified via email whenever new errata relevant to their registered systems are released. You can Link an existing Azure key vault to a variable group and map selective vault secrets to the variable group. (BZ#1965969), Previously, system proxy settings were not considered when requesting an AWS custom service endpoint. With this update, you can use the default specified storage class name instead of a hardcoded value. (OCPBUGSM-44041), When you apply a tuned override to a pod and delete the tuned pod to force a restart, the pod should restart and the system should run normally. For more information, see Configuring Classic Load Balancer timeouts. Most versions of Ansible OS server module did not automatically require the client to set a minimum. Note that configuration examples in this task. The VPA automatically reviews the historic and current CPU and memory resources for containers in pods and can update the resource limits and requests based on the usage values it learns. Define the corresponding Projects can be deleted from the CLI or the web console. There is currently no workaround for this issue. Are you sure you want to create this branch? For the most recent list of major functionality deprecated and removed within OpenShift Container Platform 4.11, refer to the table below. As a cluster administrator, you can enable cluster capabilities to select or deselect one or more optional components before installation or post installation. With this update, the container requests 1m of CPU and 10Mi of memory. Both the public IP and public IP configuration are dedicated to this workload. With this update, Fibre Channel volumes correctly unmount when a new kubelet starts. While creating a CRD does not automatically add any new points of failure (for example, by causing third party code to run on your API server), packages (for example, Charts) or other installation bundles often include CRDs as well as a Deployment of third-party code that implements the business logic for a new custom resource. As a result, network policies with multiple ipBlocks now work correctly. (BZ#1978303), Previously, a defect in the Cisco ACI neutron implementation that was present in Red Hat OpenStack Platform (RHOSP) version 16, caused the query for subnets belonging to a given network to return unexpected results. Previously, when writing the RHCOS image onto some disks, the qemu-img was allocating space onto the entire disk, including sparse areas. (OCPBUGSM-45884), On a dual-stack networking environment, devices and connections get stuck in an ip-check state with a default dhcp6 profile generated by the nm-initrd-generator utility. As a result, workload distruption will no longer occur for the following changes in /etc/containers/registries.conf files: Addition of a registry with mirror-by-digest-only=true, Addition of a mirror in a registry with mirror-by-digest-only=true, Appending items in unqualified-search-registries list. A complete list of the interface-specific safe sysclts that can be set is available in the documentation. Configuration affecting traffic routing. With this update, release loading is separated from reconciling so the latter does not block the former and a new condition ReleaseAccepted has been added to clarify the status of the release load. (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. For more information on how to lock down your private AKS cluster and filter outbound traffic, see: An AKS cluster with a private endpoint to the API server hosted by an AKS-managed Azure subscription. API resource allows you to define custom resources. In regional or multi-zonal clusters, this is the number of nodes per zone. When the template was removed, the secret remained. As part of that effort, with this release the following changes are in place: The OpenShift Docs GitHub repository master branch has been renamed to main. As a result, the Ingress Operator cannot cannot modify or delete a custom Kubernetes service with the same name as the OpenShift Ingress namespace that it wants to modify or remove. Ironic took this provisioning IP address when it started, and would fail when the address stopped working. This issue happens because the session prefers the redux store instead of the query parameters in the URL. Consequently, the cluster autoscaler did not remove the DNS pod from a node before removing the node. For more information, see the "Installation configuration parameters" section of the installation documentation for your platform. Consequently, the mapi_current_pending_csr was stuck at 1 until another machine approver reconciled it. OpenShift Container Platform release 4.8.44 is now available. Consequently, the alert was triggered unnecessarily on the cluster for OpenShift Container Platform 4.8. Support for virtual hardware version 13 was deprecated in OpenShift Container Platform 4.9. With this update, the feature gate JobTrackingWithFinalizers is disabled by default. (BZ#1962592), Previously, bare metal deployments failed if large packet transfers between Ironic and the RAM disk resulted in connection failures. The resulting table can be joined with the resource usage table or with BigQuery billing export. As a result, upgrade and dependency resolution behavior is consistent for namespaces containing multiple Subscription objects with the same .spec.name. This has been fixed. This update uses the correct host zone ID in the log. Previously, Insights Advisor gave no information. To install and manage Operators, Operator Lifecycle Manager (OLM) requires that Operator bundles are listed in an index image, which is referenced by a catalog on the cluster. The OpenShift Container Platform single node instance eventually recovers, though more slowly than expected. You can enable multipathing by appending kernel arguments to the coreos-installer install command so that the installed system itself uses multipath beginning from the first boot. For more information, see Publishing a catalog containing a bundled Operator. There is currently no workaround for this issue. Which HTTP proxy action rule must you modify to allow download of the installation file? With this update, the topology view shows a LimitExceeded state for clusters with more than 100 nodes. Consequently, the oc client returned a panic error and crashed. (BZ#1927013), Previously, launching the OpenShift Container Platform web console may be slow. The authentication and openshift-apiserver Operators now ignore the oauth-apiserver.openshift.io/secure-token-storage annotation when picking the audit policy of a cluster. and the environment variables INGRESS_HOST and SECURE_INGRESS_PORT set. Security, bug fix, and enhancement updates for OpenShift Container Platform 4.8 are released as asynchronous errata through the Red Hat Network. This update takes the users region into account when generating the URL and selects the correct public endpoint. Now, when the template instance is removed, the secret is also removed. For legacy applications that are sensitive to the capitalization of HTTP header names, use the Ingress Controller spec.httpHeaders.headerNameCaseAdjustments API field to accommodate legacy applications until they can be fixed.
