What's Changed

Warning
Activegate Authtoken support is now enabled by default

• requires additional api token scope: activeGateTokenManagement.create
• feature.dynatrace.com/activegate-authtoken=false to disable

• Improve resilience of the CSI driver

  • split up single container into server and provisioner container: server is available to handle mount/unmount requests if the provisioner uses too much memory
  • in case of issues in the CSI driver application pods are no longer blocked forever, instead empty files are mounted so the pods can start up (no monitoring, but pods are available)
  • defaults to 10 attempts, with each attempt happening when the pod restarts (see container restart policy for information on exponential back-off)

• Signed images on Dockerhub and GCR using cosign

  • verify image with public key

   cosign verify --key https://github.com/Dynatrace/dynatrace-operator/releases/download/v0.9.0/key.pub \
   	docker.io/dynatrace/dynatrace-operator:v0.9.0
  

  • verify image without key

   COSIGN_EXPERIMENTAL=1 cosign verify docker.io/dynatrace-operator:v0.9.0
  

• Add troubleshoot subcommand to diagnose common setup issues

  • can be run on any pod that uses the operator image

    kubectl exec deploy/dynatrace-operator -n dynatrace -- dynatrace-operator troubleshoot
    

• Update CSI driver container resource requests/limits

  • server (previously part of driver container): 50m cpu / 100Mi memory
  • provisioner (previously part of driver container): 300m cpu / 100Mi memory
  • registrar: 20m cpu / 30Mi memory
  • livenessprobe: 20m cpu / 30Mi memory

Bugfixes 🪲

• Add tolerations for ARM architecture to Operator components by default
• Support readOnlyRootFilesystem security context in injected init containers
• Fix .json format of metadata enrichment file

Core changes 🎉

• Add nodes/metrics permission to Operator cluster role by default
• Upgrade operator base image from ubi8-micro to ubi9-micro
• Restart webhook when OneAgentAPM CRD is present instead of silently failing
• Add validation for common issue with disabling volume storage when CSI driver is enabled
• Add tar to operator image
  • allows copying files from container by using kubectl cp

Helm changes ⛑️

• Add configurable kubeletPath
• split csidriver.resources to allow configuration of different containers
  • ⚠️ --reuse-values or same values file will no longer set resource requests/limits for provisioner container
  • csidriver.server.resources, csidriver.provisioner.resources, csidriver.registrar.resources and csidriver.livenessprobe.resources can be used to set requests/limits per container
• Adds toleration for arm and amd to operator components
