Solution Daemonsets
- Good example DaemonSet:
apiVersion: apps/v1 kind: DaemonSet metadata: name: elasticsearch namespace: kube-system spec: selector: matchLabels: name: elasticsearch template: metadata: labels: name: elasticsearch spec: containers: - name: elasticsearch image: registry.k8s.io/fluentd-elasticsearch:1.20 - How many DaemonSets are there in all of the namespaces:
kubectl get daemonsets -a - How many nodes is a daemonset pod assigned to*
Can find this from kubectl get daemonsets -A - To find more information about a particular Daemonset, this is done via
kubectl describe daemonsets <daemonset> -n <namespace_name> - An easier way to deploy a daemonset is to use the
dry-runoption for a Deployment and edit that.kubectl create deployment elasticsearch -n kube-system --image=k8s.gcr.io/fluentd-elasticsearch:1.20 --dry-run=client -o yaml > yaml_file.yaml
