Container Monitoring 4.0.0
Last updated on 20 September, 2023What’s New
Support for Scheduling Multiple Collector Pods on Single Node
You can now schedule multiple collector pods on a single node if the collector replicas are greater than the number of available nodes. If you want to restrict the scheduling of a single pod to a single node, in your configuration file, set the allowMultipleCollectorsOnNode parameter to false.
Support for Providing Affinity Rule for Collector Pod
You can now provide a customized affinity rule for the collector pod. For scheduling a collector pod on any existing node referencing the key “name” with the value “collector”, add the podAffinity parameter in the configuration file as follows:
argus:
collector:
affinity:
podAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchLabels:
app.kubernetes.io/name: collector
topologyKey: kubernetes.io/hostnameFor more information, see Assigning Pods to Nodes from Kubernetes documentation.
