Infinispan Operator 0.3.0 expands container and security configuration!

With this release of the Infinispan Operator, you can configure explicit CPU and memory limits for individual containers. The defaults are 0.5 CPUs and 512Mi of memory.

The Operator also lets you pass extra JVM options, which is useful for tracking native memory consumption or extra GC logging parameters.

Starting with 0.3.0, credentials are automatically generated for data connector and management users when you instantiate the Infinispan Operator.

The default usernames are developer and admin for the data connector user and management user, respectively.

Generated passwords are stored in Kubernetes Secret instances. You can extract the passwords as follows:

For convenience, the default usernames are also stored in the secret. Using the jq command line tool, you can inspect both the username and password values with a single command:

If you want to set custom credentials for the data connector and management users, create Kubernetes Secret instances as follows:

When using a Credentials type authentication, the referenced secrets must contain username and password fields.

The easiest way to get started with the Infinispan Operator is via the simple tutorial. The Operator is compatible with vanilla Kubernetes environments, such as Minikube, as well as Red Hat OpenShift.

Install the Infinispan Operator directly from the Operator Hub, which is available out of the box on all OpenShift 4 versions. If you’re using a vanilla Kubernertes environment, you might need to install the Operator Lifecycle Manager before you can install via the Operator Hub.

The Infinispan Operator is also included in the community for Kubernetes Operators is available from operatorhub.io.

The Operator configuration does not yet provide all capabilities available for Infinispan servers. We’re working through a process of configuration specification that distills the server configuration into a simple, easy to use, set of configuration options. The current proposal is being discussed openly here.

Infinispan 10 brings a brand new server that’s no longer based on WildFly. The Operator 0.x series will remain focused on Infinispan 9.x server, with Operator 1.x series focusing on Infinispan 10 and onwards.
