VictoriaLogs Helm方式部署

VictoriaLogs Helm方式部署

官方文档： https://docs.victoriametrics.com/victorialogs/quickstart/#helm-charts

单节点部署

先决条件

git、kubectl、helm、helm-doc

helm-doc 应该没用 我不需要他重新生成readme

图表详情

  • victorialogs 单节点部署
  • 用于从Pod中收集日志的部署向量

安装部署

github helm-chart

离线文件

基础环境准备

依赖创建好的pvc（或storageClass 目前rs10-k8s集群没有）

  1. victorialogs-namespace.yaml
  2. victorialogs-pvc.yaml

修改chart中的默认值

通过脚本修改参数（victorialogs-install-by-helm.sh）并执行helm install

install报错1：k8s版本过低

Error: INSTALLATION FAILED: chart requires kubeVersion: >=1.25.0-0 which is incompatible with Kubernetes v1.18.3

强行修改Chart.yaml中的kubeVersion要求 将其改为现在用的v1.18

install报错2: 命名空间参数位置错误导致命名空间识别错误
部署命令为: 
helm install victorialogs-single . -n victorialogs 
    --set server.image.registry=harbor.registry.com 
    --set server.image.repository=library/victoria-logs 
    --set server.image.tag=v1.21.0-victorialogs 
    --set server.retentionDiskSpaceUsage=10 
    --set server.persistentVolume.name=victorialogs-pvc 
    --set server.persistentVolume.existingClaim=victorialogs-pvc 
    --set server.persistentVolume.size=10Gi 
    --set server.service.nodePort=39428 
    --set server.service.type=NodePort
 
Error: 
INSTALLATION FAILED: 
    Unable to continue with install:

install报错解决 改为直接使用helm命令 不在借助shell脚本

修改pv挂载文件夹的权限

查阅values.yaml可知 容器默认用户id为1000 具体如下：

  # -- Pod's security context. Details are [here](https://kubernetes.io/docs/tasks/configure-pod-container/security-context/)
  podSecurityContext:
    enabled: true
    fsGroup: 2000
    # 非root用户
    runAsNonRoot: true
    # 用户id
    runAsUser: 1000

据此 登陆 nfs服务器 修改对应文件夹的权限

cd /rscloud/nfs && chown -R 1000:1000 victorialogs-pv

至此 pod 启动成功 对外端口为 39428

尝试访问 http://ip:39428 访问成功 部署初步成功
