MongoDB Kubernetes Enterprise Operator 1.20.1

This release fixes an issue that prevented upgrading the Kubernetes Operator to 1.20.0 in OpenShift. Upgrade to this release instead.

MongoDBOpsManager Resource

• Added support for votes, priority and tags by introducing the spec.applicationDatabase.memberConfig.votes, spec.applicationDatabase.memberConfig.priority
  and spec.applicationDatabase.memberConfig.tags field.
• Introduced automatic change of the AppDB's image version suffix -ent to -ubi8.
  • This enables migration of AppDB images from the legacy repository (quay.io/mongodb/mongodb-enterprise-appdb-database-ubi) to the new official one (quay.io/mongodb/mongodb-enterprise-server) without changing the version in MongoDBOpsManager's applicationDatabase.version field.
  • The change will result a rolling update of AppDB replica set pods to the new, official images (referenced in Helm Chart in values.mongodb.name field), which are functionally equivalent to the previous ones (the same MongoDB version).
  • Suffix change occurs under specific circumstances:
    • Helm setting for appdb image: mongodb.name will now default to mongodb-enterprise-server.
    • The operator will automatically replace the suffix for image repositories
      that end with mongodb-enterprise-server.
      Operator will replace the suffix -ent with the value set in the environment variable
      MDB_IMAGE_TYPE, which defaults to -ubi8.
      For instance, the operator will migrate:
      • quay.io/mongodb/mongodb-enterprise-server:4.2.11-ent to quay.io/mongodb/mongodb-enterprise-server:4.2.11-ubi8.
      • MDB_IMAGE_TYPE=ubuntu2024 quay.io/mongodb/mongodb-enterprise-server:4.2.11-ent to quay.io/mongodb/mongodb-enterprise-server:4.2.11-ubuntu2024.
      • The operator will do the automatic migration of suffixes only for images
        that reference the name mongodb-enterprise-server.
        It won't perform migration for any other image name, e.g.:
        • mongodb-enterprise-appdb-database-ubi:4.0.0-ent will not be altered
      • To stop the automatic suffix migration behavior,
        set the following environment variable to true: MDB_APPDB_ASSUME_OLD_FORMAT=true
        or alternatively in the following helm chart setting: mongodb.appdbAssumeOldFormat=true
• Added support for defining bare versions in spec.applicationDatabase.version. Previously, it was required to specify AppDB's version with -ent suffix. Currently, it is possible to specify a bare version, e.g. 6.0.5 and the operator will convert it to 6.0.5-${MDB_IMAGE_TYPE}. The default for environment variable MDB_IMAGE_TYPE is -ubi8.

Bug fixes

• Fixed MongoDBMultiCluster not watching Ops Manager's connection configmap and secret.
• Fixed support for rotating the clusterfile secret, which is used for internal x509 authentication in MongoDB and MongoDBMultiCluster resources.

Helm Chart

• All images reference ubi variants by default (added suffix -ubi)
  • quay.io/mongodb/mongodb-enterprise-database-ubi
  • quay.io/mongodb/mongodb-enterprise-init-database-ubi
  • quay.io/mongodb/mongodb-enterprise-ops-manager-ubi
  • quay.io/mongodb/mongodb-enterprise-init-ops-manager-ubi
  • quay.io/mongodb/mongodb-enterprise-init-appdb-ubi
  • quay.io/mongodb/mongodb-agent-ubi
  • quay.io/mongodb/mongodb-enterprise-appdb-database-ubi
• Changed default AppDB repository to official MongoDB Enterprise repository in values.mongodb.name field: quay.io/mongodb/mongodb-enterprise-server.
• Introduced values.mongodb.imageType variable to specify a default image type suffix added to AppDB's version used by MongoDBOpsManager resource.

Breaking changes

• Removal of appdb.connectionSpec.Project since it has been deprecated for over 2 years.
