v0.2.5 - Add Toleration and Node Selector support for ZK

Upgrade Notes

New Features

• Adding missing inputs for ZK tolerations and node selector support (#108)

v0.2.4 - Bug Fixes and some new features

Upgrade Notes

Dependency Upgrades

• The default supported version of the Zookeeper Operator has been upgraded to 0.2.6 (#93)
  This will not affect clouds already created before upgrading the Solr Operator, however we do suggest first upgrading your Zookeeper images to pravega/zookeeper:0.2.6, then upgrading your zookeeper operator version to pravega/zookeeper-operator:0.2.6

Bug Fixes

• Fixing logging in collection util. (#92)
• Fixing int to string conversion in logging (#96)

New Features

v0.2.3 - Fix for non-ingress-addressed SolrClouds

Upgrade Notes

All non-ingress Solr Node addresses will change to use port 8983 when the operator is upgraded. The nodes will no longer be addressable with port 80.

Bug Fixes

• The headlessService for non-ingress SolrClouds no longer maps ports (#87)
  • This caused issues with solrCloud nodes addressing other nodes in the cluster, because headlessServices do not actually allow mapping of ports.
  • SolrClouds that are deployed with ingresses will not be affected.

New Features

• The solrNode status now contains the name of the Kubernetes node it runs on. (#89)

v0.2.2 - Helm Chart and Kubernetes Resource Customization

Upgrade Notes

Deprecation Warning

• SolrCloud.spec.solrPodPolicy has been DEPRECATED in favor of the SolrCloud.spec.customSolrKubeOptions.podOptions option.
  This option is backwards compatible, but will be removed in a future version (v0.3.0).

• SolrPrometheusExporter.spec.solrPodPolicy has been DEPRECATED in favor of the SolrPrometheusExporter.spec.customKubeOptions.podOptions option.
  This option is backwards compatible, but will be removed in a future version (v0.3.0).

Bug Fixes

• The maxShardsPerNode option for SolrCollections is correctly set now (#79)

New Features

• Introduction of the Solr Operator Helm Chart (#70)
• New customization API for Kubernetes Resources. Users now have the ability to change attributes of the Kubernetes resources created by the Solr Operator.
  • SolrCloud (#74, #75)
    • StatefulSet - Labels, Annotations
    • Pod - Labels, Annotations, Volumes, EnvVars, Resources, Affinity, SecurityContext
    • Services - Labels, Annotations
    • Ingress - Labels, Annotations
    • ConfigMap - Labels, Annotations
  • SolrPrometheusExporter (#83)
    • Deployment - Labels, Annotations
    • Pod - Labels, Annotations, Volumes, EnvVars, Resources, Affinity, SecurityContext
    • Service - Labels, Annotations
    • ConfigMap - Labels, Annotations

Other

• The Prometheus Exporter example was fixed (#81)

v0.2.1 - Stability & Bug fixes

Upgrade Notes

Bug Fixes

• Rest Config NPE in the backup controller (#65)
• Infinite loop while setting defaults for SolrBackup resources (#64)
• Setting defaults and reconciling Provided ZKs with Persistence (#64)

New Features

• Solr Services (individual node + headless) are now addressable even when pods are not ready (#67)
  • This allows Solr to communicate between nodes even when the node is not "ready", which may be determined by internal solr state.
• A service account was added for the default deployment of the solr-operator (#69)
• A chRoot can now be specified for provided ZK instances for SolrClouds (#62)
• Non-root (/) chRoots are now verified, and created if necessary, before they can be used. (#62)
  • This means that StatefulSets will not be created/updated with a new ChRoot until it has been successfully verified or created.

Other Changes

• The internal directory used for backup data in the solr pod has changed to match needed directory permissions. This will cause a rolling restart of your solr cloud nodes using the backupRestoreVolume option, but there will be no other effect. (#65)
• The zkConnectionString used for provided zookeepers changed from using the string provided in the ZkCluster.Status, which used an IP, to using the service name. This will cause a rolling restart of your solr cloud nodes using the provided zookeeper option, but there will be no data loss. (#62)

v0.2.0 - Upgrade to Kubuilder 2.0 and Go Modules

Upgrade Notes

• An upgrade to the ZKOperator version 0.2.4 is required
• SolrCloud.zookeeperRef.provided.zookeeper.persistentVolumeClaimSpec has been deprecated in favor of the SolrCloud.zookeeperRef.provided.zookeeper.persistence option. This option is backwards compatible, but will be removed in a future version.
• Uses gomod instead of dep for dependency management

Bug Fixes

• Fixed status/solrPod reconciling loops.
  • If an ingress is used, the solr pods now use hostAliases to map the
    ingress URL of each solr node to the IP of the corresponding service
• Fixed a bug related to the first pod of the Solr StatefulSet starting
  without a zkConnectionString

New Features

• Added CollectionAlias CRD to manage aliases with SolrClouds & SolrCollections
