v0.2.0

What's New

This is the second public release of the NRI reference plugin collection. It demonstrates a wider range of capabilities of NRI by introducing a few new plugins. Numerous Helm chart improvements make plugin deployment easier with this release. This release is a pre-release, not production quality software.

New Plugins, Binaries

Two new plugins have been merged and are now available as part of this release:

• memory QoS: class-based or per-container adjustment of cgroup v2 memory.* control knobs
• memtierd: launch per-container memtierd instances to track and manage memory of selected workloads

Additionally a new helper binary has been added for automatically enabling NRI support in the runtime. This is available as an init container in the Helm chart deployments.

Other Improvements

• Helm repo for the charts is now available at https://containers.github.io/nri-plugins (helm repo add nri-plugins https://containers.github.io/nri-plugins)
• vastly improved Helm chart and kustomize support
• automatic enabling of NRI in the runtime during plugin deployment (see nri.patchRuntimeConfig in Helm parameters)
• improved plugin installation instructions
