k8s部署milvusdb

环境:
Os:Centos 7

前提条件,使用到的组件需要提前部署好:
kafka(单点,包含 zookeeper ):https://www.cnblogs.com/hxlasky/p/18615374
etcd(单点):https://www.cnblogs.com/hxlasky/p/18641819
minio(单点):https://www.cnblogs.com/hxlasky/p/18643317

1.创建namespace
kubectl create namespace middleware

2.安装 cert-manager(不需要修改镜像)
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.16.2/cert-manager.yaml

Milvus Operator 需要一个 cert-manager 来管理安全通信的证书。请确保您安装的是 cert-manager 版本为 1.1.3 或以上版本。请运行以下命令进行安装：
配置文件 cert-manager.yaml 提前下载好

若已经下载好的可以执行如下命令:

[root@master soft]# cd /root/my_yaml
[root@master soft]# kubectl apply -f cert-manager.yaml
查看(其他节点执行也是一样的输出)

[root@master soft]#  kubectl get pods -n cert-manager
NAME                                      READY   STATUS    RESTARTS   AGE
cert-manager-679895f5-qtrxk               1/1     Running   0          81s
cert-manager-cainjector-b78544fd4-jb2gm   1/1     Running   0          81s
cert-manager-webhook-cd8bbbd67-ll9r9      1/1     Running   0          81s

3. 安装 Milvus Operator
[root@yunwei-k8s-dev milvus]# kubectl get pod -n milvus-operator
配置文件可以提前下载到服务器上
cert-manager 启动并运行后，您可以安装 Milvus Operator。运行以下命令使用 kubectl 部署 Milvus Operator
kubectl apply -f https://github.com/zilliztech/milvus-operator/releases/latest/download/deployment.yaml
若已经下载的可以执行如下命令:

[root@master soft]# cd /root/my_yaml
[root@master soft]# kubectl apply -f deployment.yaml
您可以使用以下命令检查 Milvus Operator pod 是否正在运行:

[root@master soft]# kubectl get pods -n milvus-operator
NAME                              READY   STATUS              RESTARTS   AGE
milvus-operator-545894474-dvdzr   0/1     ContainerCreating   0          34s
milvus-operator-checker-k8b98     0/1     ErrImagePull        0          34s

查看日志:

kubectl describe po milvus-operator-9598c4bb6-c2nbz -n milvus-operator
日志如下:
  Warning  Failed     31s                kubelet            Failed to pull image "milvusdb/milvus-operator:v1.1.4": rpc error: code = DeadlineExceeded desc = failed to pull and unpack image "docker.io/milvusdb/milvus-operator:v1.1.4": failed to resolve reference "docker.io/milvusdb/milvus-operator:v1.1.4": failed to do request: Head "https://registry-1.docker.io/v2/milvusdb/milvus-operator/manifests/v1.1.4": dial tcp 128.242.245.253:443: i/o timeout

解决办法：
删除应用
kubectl delete -f deployment.yaml

修改文件
vi deployment.yaml
找到如下语句:
image: 'milvusdb/milvus-operator:v1.1.4'
修改为自己下载的镜像
image: 'registry.cn-shenzhen.aliyuncs.com/hxlk8s/milvus-operator:v1.1.2'

再次创建应用
[root@master soft]# /root/my_yaml
[root@master soft]# kubectl apply -f deployment.yaml

[root@master soft]# /root/my_yaml
[root@master soft]# kubectl apply -f deployment.yaml
[root@master my_yaml]# kubectl get pods -n milvus-operator
NAME                               READY   STATUS    RESTARTS   AGE
milvus-operator-554547495d-rx2lb   1/1     Running   0          3m57s

4.创建Secret

/root/my_yaml
vi milvus_secret.yaml

apiVersion: v1
kind: Secret
metadata:
  name: milvus-s3-secret
  namespace: middleware
type: Opaque
stringData:
  accesskey: LfUVNGzh4N1VJ2BQ
  secretkey: YrHQBmXpE0OMrNH2PasUeRZutUYPvWlM

这里的accesskey和secretkey 需要在
