helm部署Vector agent

环境信息

  1. Kubernetes:v1.20.6
  2. Helm:v3.5.2

本安装前准备工作

1. 同步海外源镜像

在国内环境部署应用,经常因为获取国外源站容器镜像超时,导致部署失败,可以提前将容器镜像同步到本地镜像仓库中,以自有镜像仓库uhub.service.ucloud.cn/ucloud_pts 为例,login仓库,执行命令: docker login uhub.service.ucloud.cn/ucloud_pts
需要同步镜像列表如下:

docker.io/timberio/vector:0.15.X-debian

关于docker pull tag push 操作可以参考:

3. 创建 imagePullSecrets

创建容器集群访问仓库地址 uhub.service.ucloud.cn/ucloud_pts,拉取镜像需要的 secret

kubectl create namespace logsystem
kubectl create secret docker-registry registry-vector-secret \
        --namespace=logsystem \
        --docker-server=uhub.service.ucloud.cn/ucloud_pts \
        --docker-username='xxxxxx' \
        --docker-password='xxxxxx'

4. 添加 Helm仓库

这里选用 timberio 提供的chart仓库

helm repo add timberio https://packages.timber.io/helm/latest
helm repo update

5. 定义配置,完成部署

cat > vector-agent-values.yaml << EOF
image:
  repository: uhub.service.ucloud.cn/ucloud_pts
  tag: "0.15.X-debian"
imagePullSecrets:
  - registry-vector-secret
extraVolumes:

    hostPath:
      path: /data/log/pods/

    mountPath: /data/log/pods/
customConfig:

      inputs:

      endpoint: "https://loki-gateway.onwalk.net/loki/api/v1/push"
      labels:
        "cluster": "admin"
      encoding:
        codec: json
        timestamp_format: rfc3339
      healthcheck:
        enabled: false
EOF
helm upgrade --install vector-agent timberio/vector-agent -n loki -f vector-agent-values.yaml
kubectl rollout restart -n loki daemonset/vector-agent

helm upgrade --install vector-agent  -n logsystem    \
     -f vector-agent-values.yaml timberio/vector-agent
kubectl rollout restart -n loki daemonset/vector-agent
