k8s 安装kubevirt v0.59.0 (k3s v1.26.4)-526互联

1.安装kubevirt-operator.yaml （可以直接指定VERSION=v0.59.0-alpha.2；可以直接先在浏览器访问github下载yaml）

export VERSION=$(curl -s https://api.github.com/repos/kubevirt/kubevirt/releases | grep tag_name | grep -v -- '-rc' | sort -r | head -1 | awk -F': ' '{print $2}' | sed 's/,//' | xargs)echo $VERSION

kubectl create -f https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-operator.yaml

验证：kubectl -n kubevirt get pod

2.安装kubevirt-cr.yaml

kubectl create -f https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-cr.yaml

如果需要开启功能特性（如热迁移、热插拔、dataVolume），需要先编辑kbuevirt.cr.yaml

---
apiVersion: kubevirt.io/v1
kind: KubeVirt
metadata:
  name: kubevirt
  namespace: kubevirt
spec:
  certificateRotateStrategy: {}
  configuration:
    developerConfiguration:
      featureGates:
      - LiveMigration # 热迁移特性
      - DataVolumes  # dataVolume特性
      - HotplugVolumes  # 热插拔特性
      - HostDisk  # 本地磁盘
  customizeComponents: {}
  imagePullPolicy: IfNotPresent
  workloadUpdateStrategy: {}
  infra:
    replicas: 1 # api副本数调整为1，使用默认的2

验证：kubectl -n kubevirt get kubevirt

3.安装CDI，用于使用dataVolume

cdi-operator: v1.55.2

kubectl apply -f cdi-operator.yaml

验证：kubectl -n cdi get pod

kubectl apply -f cdi-cr.yaml

验证：kubectl -n cdi get cdi

4.创建dataVolume

如果k3s版本过低（本人当时遇到错误的版本是：k3s v1.18.5），会提示没有dataVolume类型的错误

kubectl apply -f dataVolume.yaml

apiVersion: cdi.kubevirt.io/v1beta1
kind: DataVolume
metadata:
  name: example-blank-dv
spec:
  source:
    blank: {}
  pvc:
    accessModes:
      - ReadWriteOnce
    resources:
      requests:
        storage: 1Gi

验证：kubectl get pvc

5.创建vm

kubectl apply -f vm.yaml

apiVersion: kubevirt.io/v1
kind: VirtualMachine
metadata:
  name: testvm
spec:
  running: false
  template:
    metadata:
      labels:
        kubevirt.io/size: small
        kubevirt.io/domain: testvm
    spec:
      domain:
        devices:
          disks:
            - name: containerdisk
              disk:
                bus: virtio
            - name: cloudinitdisk
              disk:
                bus: virtio
          interfaces:
          - name: default
            masquerade: {}
        resources:
          requests:
            memory: 64M
      networks:
      - name: default
        pod: {}
      volumes:
        - name: containerdisk
          containerDisk:
            image: quay.io/kubevirt/cirros-container-disk-demo
        - name: cloudinitdisk
          cloudInitNoCloud:
            userDataBase64: SGkuXG4=

验证：kubectl get vm
