Changelog

cgroups v2 are now fully supported

The injector now supports both cgroups v1 and cgroups v2 systems. There's no additional configuration needed. The injector will automatically detect which version the system is running and will adapt the injection logic based on that.

Major changes

Changes to the network disruption cloud providers configuration (#633)

You can now configure the IP ranges URL for each cloud providers supported in the network disruption, as well as disabling them (individually or all at once).

      cloudProviders:
        disableAll: false
        pullInterval: 24h
        aws:
          enabled: true
          ipRangesURL: https://ip-ranges.amazonaws.com/ip-ranges.json
        gcp:
          enabled: true
          ipRangesURL: https://www.gstatic.com/ipranges/goog.json
        datadog:
          enabled: true
          ipRangesURL: https://ip-ranges.datadoghq.com/

Targets can be filtered based on annotations (#630)

In addition to the resource label selector, you can now add an extra filtering based on annotations. It does NOT replace the label selector: resources are still selecting based on this criteria and are then filtered based on provided annotations. See the example here.
