kubernetes-client v8.0.0

Bugs

  • Fix #8105: requests hanging when a retry action, retry decision, or response cleanup throws an exception.
  • Fix #7374: (crd-generator) Generated CRDs no longer prune or reject what the client writes: Object, raw Map, List<Object>, raw collection, @JsonUnwrapped and polymorphic properties keep their content, and date and time types only declare a format their values match (Duration, LocalDateTime and the partial types lose date-time). Optional properties get their value type’s schema instead of preserving unknown fields, see the migration guide
  • Fix #6779: (httpclient-jetty) 401 responses without a WWW-Authenticate header, which is how the API server sends them, are returned with their body instead of failing with “HTTP protocol violation: Authentication challenge without WWW-Authenticate header”
  • Fix #6779: (httpclient-jetty, httpclient-vertx, httpclient-vertx-5) A proxy password containing a colon, or a proxy URL with a user and no password, is now used to authenticate with the proxy, instead of falling back to a Proxy-Authorization request header that HTTPS requests carry through the proxy tunnel to the API server
  • Fix #6779: A proxy username configured without a password is sent with an empty password instead of null, and a proxy URL with a user and no password as user: instead of user (RFC 7617)
  • Fix #8134: (httpclient-jetty) A failed WebSocket handshake no longer calls the listener’s onError, the returned future already fails with it. When the handshake was retried, this ended watches and exec/attach sessions before the retry could open them
  • Fix #8134: (httpclient-jetty) Credentials for a SOCKS5 proxy are sent to it
  • Fix #8134: (httpclient-jetty, httpclient-vertx) Proxy credentials that aren’t Basic user:password are only added as a Proxy-Authorization header to the requests an HTTP proxy reads. HTTPS and WSS requests, WebSockets that Vert.x tunnels, and requests through a SOCKS proxy carried them to the API server
  • Fix #8134: (httpclient-vertx-5) Proxy credentials that aren’t Basic user:password are sent to the HTTP proxy by Vert.x, on the CONNECT too, so HTTPS and WebSocket requests through a proxy that requires them work, and they no longer reach the API server
  • Fix #8134: (httpclient-okhttp) A 407 from the API server (through pods/proxy for example) is no longer answered with the proxy credentials, which went through the proxy tunnel to it, and credentials the proxy rejected aren’t sent again
  • Fix #8140: (httpclient-vertx-5) A request whose connection is closed before it could be written fails with an IOException, and is retried, instead of hanging until the request timeout (seen on Windows)
  • Fix #8134: (httpclient-jetty) Cookies set by a response are no longer sent back on later requests and WebSocket upgrades, like with the other HttpClient implementations
  • Fix #8109: A java.sql.Date written as yyyy-MM-dd is read as a local date instead of the previous day west of UTC. Year, Month, java.sql.Date and Locale keep their 7.x wire format, mappers you build yourself need the new Jackson2JdkTypesModule, see the migration guide
  • Fix #8109: (crd-generator) byte[], ByteBuffer, char[], Year and java.sql.Date schemas match what the client writes (byte[] and ByteBuffer are format: byte strings), so the API server no longer rejects them. @PrinterColumn on a LocalDate is a string column instead of a date column that showed <invalid>
  • Fix #8008: (httpclient-vertx-5) Requests with an InputStream body and Expect: 100-continue (binary builds) no longer hang, and an InputStream body of known length is sent with Content-Length instead of chunked
  • Fix #8139: (httpclient-okhttp) WebSockets answer the server’s Close frame even when the listener doesn’t, so port forwarding and custom listeners release the connection instead of waiting for the server to drop it
  • Fix #8152: (httpclient-vertx, httpclient-vertx-5, httpclient-jetty, httpclient-jdk) WebSockets send a ping every Config#websocketPingInterval (30s by default), like OkHttp already did, so load balancers that close idle connections no longer drop quiet watches

Improvements

  • Fix #8109: (crd-generator) int/Integer and long/Long properties get format: int32 and format: int64, like controller-gen
  • Fix #7987: (kubernetes-client-api) withShardSelector accepts a typed ShardSelector (ShardSelector.builder().addShard(0, 4).addShard(2, 4).build()) next to the raw expression String, so the shardRange(...) CEL grammar and its hexadecimal bounds don’t have to be written by hand

New Features

  • Fix #8041: Typed DSL for the resources added in Kubernetes 1.37: certificates().v1().podCertificateRequests(), dynamicResourceAllocation().v1().deviceTaintRules(), storageMigration().v1().storageVersionMigrations() and scheduling().v1beta1() podGroups() and workloads(), plus certificates().v1beta1().podCertificateRequests() and storageMigration().v1beta1().storageVersionMigrations(). kubernetes-model-policy also ships the lifecycle.k8s.io/v1alpha1 model (Eviction and EvictionRequest)

Note: Breaking changes

  • Check detailed migration documentation for breaking changes in 8.0.0
  • Fix #8041: (kubernetes-client-api) runtimeClasses() and network().ingresses() (and network().ingress()) use the v1 models instead of v1beta1 ones Kubernetes no longer serves, see the migration guide
  • Fix #7374: Moved to Jackson 3 (tools.jackson coordinates and packages). The default serialization keeps the Jackson 2 behavior for custom types, see the migration guide
  • Fix #7987: (kubernetes-client-api) Filterable#withShardSelector also accepts a typed ShardSelector, so a literal withShardSelector(null) no longer compiles, see the migration guide
  • Fix #8031: (crd-generator) Removed the deprecated CRD Generator v1 (crd-generator-api and crd-generator-apt). Migrate to crd-generator-api-v2 with the Maven plugin, the CLI tool, or the Gradle build script recipe, see the migration guide
  • Fix #8009: Moved Java baseline from 11 to 17. In addition to the runtime requirement, the Maven plugins, the Gradle plugin and the annotation processor now require a Java 17+ JVM to run the build, and the OSGi bundles declare osgi.ee=JavaSE 17
  • Fix #8050: (karaf) The kubernetes-karaf feature repository no longer defines its own scr feature. kubernetes-client now depends on the scr feature provided by the Karaf distribution, which supplies the Declarative Services API bundles and the scr:* shell commands
  • Fix #8142: (knative) Serving RevisionSpec replaces workloadRef with schedulingGroup and adds evictionResponders, like the core PodSpec since Kubernetes 1.37
  • Fix #8133: (open-cluster-management) DiscoveredClusterSpec drops owner and DiscoveredClusterCondition drops lastUpdateTime
  • Fix #8148: (openshift-model) Model class io.fabric8.openshift.api.model.customresourcestatus.conditions.v1.Condition removed, Hive ClusterDeploymentCustomizationStatus conditions use the Kubernetes Condition
  • Fix #8148: (openshift-model-config) ClusterImagePolicySpec and ImagePolicySpec policies are ImageSigstoreVerificationPolicy and their roots of trust ImagePolicyFulcioCAWithRekorRootOfTrust, ImagePolicyPKIRootOfTrust and ImagePolicyPublicKeyRootOfTrust. Model classes FulcioCAWithRekor, PKI, Policy and PublicKey removed
  • Fix #8148: (openshift-model-config) GCPPlatformStatus drops serviceEndpoints, model class GCPServiceEndpoint removed
  • Fix #8148: (openshift-model-hive) oVirt support removed: ClusterDeprovisionPlatform, MachinePoolPlatform and Platform drop ovirt, model classes OvirtClusterDeprovision and the io.fabric8.openshift.api.model.hive.ovirt.v1 package removed
  • Fix #8148: (openshift-model-hive) vSphere MachinePool.osDisk uses the installer io.fabric8.openshift.api.model.installer.vsphere.v1.OSDisk, model class io.fabric8.openshift.api.model.hive.vsphere.v1.OSDisk removed. The module now depends on openshift-model-installer, openshift-model-machine and openshift-model-operator
  • Fix #8148: (openshift-model-installer) GCP PSCEndpoint drops region
  • Fix #8148: (openshift-model-machineconfiguration) v1alpha1 model classes MachineConfigNode, PinnedImageSet and their related types removed, use the v1 ones
  • Fix #8133: (open-cluster-management) MultiClusterHubSpec drops customCAConfigmap, enableClusterBackup, enableClusterProxyAddon, hive, ingress and separateCertificateManagement. Model classes BackupConfig, ExternalDNSAWSConfig, ExternalDNSConfig, ExternalDNSGCPConfig, FailedProvisionConfig, HiveConfigSpec, HiveConfigStatus, IngressSpec and VeleroBackupConfig removed
  • Fix #8133: (open-cluster-management) Observability PlatformMetricsSpec and UserWorkloadMetricsSpec replace collection with default (PlatformMetricsCollectionSpec and UserWorkloadMetricsCollectionSpec removed), and PlatformNamespaceRightSizingRecommendationSpec is renamed to PlatformRightSizingRecommendationSpec
  • Fix #8100: (tekton) Model classes Template and AffinityAssistantTemplate moved from package io.fabric8.tekton.pod to io.fabric8.tekton.unversioned, since tekton pipeline 1.16.0 declares them as +versionName=unversioned
  • Fix #6779: (httpclient-jetty) Moved from Jetty 11 to Jetty 12.1, see the migration guide
  • Fix #8008: kubernetes-client and openshift-client default to the Vert.x 5 HttpClient (kubernetes-httpclient-vertx-5) instead of Vert.x 4 (kubernetes-httpclient-vertx), see the migration guide
