Infinispan Operator 1.1.0 is out!
We’re pleased to announce version 1.1.0 of the Infinispan Operator for Kubernetes and OpenShift.
This release includes a bunch of very exciting features! Let’s dig into them:
Infinispan Operator 1.1.0 is rated at the
Full Lifecycle capacity level, which
means the Operator now provides advanced cluster management capabilities and
functionality to handle demanding workloads.
One of the key new features in this release is graceful shutdown, which lets you bring clusters down safely to avoid data loss.
During cluster shutdown, caches can passivate in-memory entries to persistent storage along with the internal Infinispan state that maps which nodes own which entries. When you bring Infinispan clusters back, all your data is restored to memory.
Check out the Graceful Shutdown docs for more information.
Graceful shutdown also enables the Infinispan Operator to perform reliable upgrades.
When a new version of the Infinispan Operator starts, it checks for running Infinispan clusters that were created by an older Operator version.
If the Operator detects a cluster that requires upgrade, it invokes a graceful shutdown on the cluster and then brings it back with the new Infinispan version.
You can perform upgrade manually or automatically with the Operator Lifecycle Manager on OpenShift.
Note that Operators installed via the OperatorHub on OpenShift Container Platform are managed by the Operator Lifecyle Manager.
Cache vs DataGrid
This version of the Infinispan Operator delivers Cache and DataGrid services.
By default the Operator starts Infinispan clusters as Cache services, which provides a quick way to set up in-memory caching that stores data off-heap and keeps single copies of data in the cluster.
DataGrid services, on the other hand, are suited to more advanced use cases where you control and define the configuration that you need.
The Infinispan Operator simplifies cross-site replication set up with DataGrid services so you can back data up between separate Kubernetes or OpenShift clusters.
All you need to do is specify which type of external Kubernetes service to expose, the list of all backup locations, access secrets, and the local site name.

Automatic TLS configuration
If you’re running on Openshift and have a service that serves certificates, the Operator automatically asks for certificates sets up TLS for your endpoint connections. Encrypted by default with zero effort!
