环境信息
- Kubernetes：v1.20.6
- 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：
- https://docs.docker.com/engine/reference/commandline/pull/
- https://docs.docker.com/engine/reference/commandline/tag/
- https://docs.docker.com/engine/reference/commandline/push/
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
