Use context: kubectl config use-context k8s-c1-H

Use Namespace project-tiger for the following. Create a DaemonSet named ds-important with image httpd:2.4-alpine and labels id=ds-important and uuid=18426a0b-5f59-4e10-923f-c0e078e82462. The Pods it creates should request 10 millicore cpu and 10 mebibyte memory. The Pods of that DaemonSet should run on all nodes, also controlplanes.

译文:

使用命名空间 project-tiger 进行如下操作。创建一个名为 ds-important 的DaemonSet，镜像为 httpd:2.4-alpine ，标签 id=ds-important ， uuid=18426a0b-5f59-4e10-923f-c0e078e82462 。它所创建的Pod应该要求10个毫核cpu和10个mebibyte内存。该DaemonSet的Pod应该在所有的节点上运行，包括控制平面。

解答:

通过创建deployment 来创建 daemonset

k -n project-tiger create deployment --image=httpd:2.4-alpine ds-important $do > 11.yaml

vim 11.yaml

11.yaml

# 11.yaml
apiVersion: apps/v1
kind: DaemonSet                                     # change from Deployment to Daemonset
metadata:
  creationTimestamp: null
  labels:                                           # add
    id: ds-important                                # add
    uuid: 18426a0b-5f59-4e10-923f-c0e078e82462      # add
  name: ds-important
  namespace: project-tiger                          # important
spec:
  #replicas: 1                                      # remove
  selector:
    matchLabels:
      id: ds-important                              # add
      uuid: 18426a0b-5f59-4e10-923f-c0e078e82462    # add
  #strategy: {}                                     # remove
  template:
    metadata:
      creationTimestamp: null
      labels:
        id: ds-important                            # add
        uuid: 18426a0b-5f59-4e10-923f-c0e078e82462  # add
    spec:
      containers:
      - image: httpd:2.4-alpine
        name: ds-important
        resources:
          requests:                                 # add
            cpu: 10m                                # add
            memory: 10Mi                            # add
      tolerations:                                  # add
      - effect: NoSchedule                          # add
        key: node-role.kubernetes.io/control-plane  # add
#status: {}                                         # remove

应用文件创建pod,并检查状态

k -f 11.yaml create
k -n project-tiger get ds
k -n project-tiger get pod -l id=ds-important -o wide
