Percona Kubernetes Operator for Percona Server for MongoDB 1.2.0

Percona announces the Percona Kubernetes Operator for Percona Server for MongoDB 1.2.0 release on September 20, 2019. This release is now the current GA release in the 1.2 series. Install the Kubernetes Operator for Percona Server for MongoDB by following the instructions.

The Operator simplifies the deployment and management of the Percona Server for MongoDB in Kubernetes-based environments. It extends the Kubernetes API with a new custom resource for deploying, configuring and managing the application through the whole life cycle.

The Operator source code is available in our Github repository . All of Percona’s software is open-source and free.

New Features and Improvements

  • A Service Broker was implemented for the Operator, allowing a user to deploy Percona XtraDB Cluster on the OpenShift Platform, configuring it with a standard GUI, following the Open Service Broker API.

  • Now the Operator supports Percona Monitoring and Management 2 , which means being able to detect and register to PMM Server of both 1.x and 2.0 versions.

  • Data-at-rest encryption is now enabled by default unless EnableEncryption=false is explicitly specified in the deploy/cr.yaml configuration file.

  • Now it is possible to set the schedulerName option in the operator parameters. This allows using storage which depends on a custom scheduler, or a cloud provider which optimizes scheduling to run workloads in a cost-effective way.

  • The resource constraint values were refined for all containers to eliminate the possibility of an out of memory error.

Fixed Bugs

  • Oscillations of the cluster status between “initializing” and “ready” took place after an update.

  • The Operator was removing other cron jobs in case of the enabled backups without defined tasks (contributed by Marcel Heers ).

Percona Server for MongoDB is an enhanced, open source and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB Community Edition. It supports MongoDB protocols and drivers. Percona Server for MongoDB extends MongoDB Community Edition functionality by including the Percona Memory Engine, as well as several enterprise-grade features. It requires no changes to MongoDB applications or code.
