Artifactory Helm存储库无法从远程仓库中获取新的索引文件，因此需要手动设置cronjob以定期拉取索引文件和重新索引。以下是cronjob的示例：

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: helm-repo-index
spec:
  schedule: "*/30 * * * *"
  jobTemplate:
    spec:
      template:
        metadata:
          name: helm-repo-index
        spec:
          restartPolicy: OnFailure
          containers:
          - name: helm-repo-index
            image: ubuntu:latest
            command:
              - /bin/sh
            args:
              - -c
              - |
                apt-get update && apt-get install -y wget curl
                wget https://repo1.maven.org/maven2/io/github/helm/helm-search-plugin/1.15.1/helm-search-plugin-1.15.1-linux-amd64.tar.gz
                tar zxvf helm-search-plugin-1.15.1-linux-amd64.tar.gz
                mkdir -p /opt/artifactory/helm-local/charts
                mkdir -p /tmp/helm-download
                curl -o /tmp/helm-download/index.yaml https://charts.helm.sh/stable/index.yaml
                /helm-search-plugin index download /tmp/helm-download/index.yaml /opt/artifactory/helm-local/charts/

该示例将设置定时任务以每30分钟拉取和重新索引存储库中的索引文件。可以根据需求更改计划和cronjob中的命令。
