部署 GreptimeDB 单机版

在该指南中，你将学会如何在 Kubernetes 上部署 GreptimeDB 单机版。

备注

以下输出可能会因 Helm chart 版本和具体环境的不同而有细微差别。

前置条件​

创建一个测试 Kubernetes 集群​

注意

不建议在生产环境或性能测试中使用 kind。如有这类需求建议使用公有云托管的 Kubernetes 服务，如 Amazon EKS、Google GKE 或 Azure AKS，或者自行搭建生产级 Kubernetes 集群。

目前有很多方法可以创建一个用于测试的 Kubernetes 集群。在本指南中，我们将使用 kind 来创建一个本地 Kubernetes 集群。如果你想使用已有的 Kubernetes 集群，可以跳过这一步。

这里是一个使用 kind v0.20.0 的示例：

kind create cluster
Expected Output
Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.27.3) 🖼
 ✓ Preparing nodes 📦
 ✓ Writing configuration 📜
 ✓ Starting control-plane 🕹️
 ✓ Installing CNI 🔌
 ✓ Installing StorageClass 💾
Set kubectl context to "kind-kind"
You can now use your cluster with:
kubectl cluster-info --context kind-kind
Not sure what to do next? 😅  Check out https://kind.sigs.k8s.io/docs/user/quick-start/

使用以下命令检查集群的状态：

kubectl cluster-info
预期输出
Kubernetes control plane is running at https://127.0.0.1:60495
CoreDNS is running at https://127.0.0.1:60495/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
备注

中国大陆用户如有网络访问问题，可使用 Greptime 提供的位于阿里云镜像仓库的 kindest/node:v1.27.3 镜像：

kind create cluster --image greptime-registry.cn-hangzhou.cr.aliyuncs.com/kindest/node:v1.27.3

添加 Greptime Helm 仓库​

备注

中国大陆用户如有网络访问问题，可跳过这一步骤并直接参考下一步中使用阿里云 OCI 镜像仓库的方式。采用这一方式将无需手动添加 Helm 仓库。

我们提供了 GreptimeDB Operator 和 GreptimeDB 集群的官方 Helm 仓库。你可以通过运行以下命令来添加仓库：

helm repo add greptime https://greptimeteam.github.io/helm-charts/
helm repo update

检查 Greptime Helm 仓库中的 charts：

helm search repo greptime/greptimedb-standalone
Expected Output
NAME                          	CHART VERSION	APP VERSION	DESCRIPTION
greptime/greptimedb-standalone	0.1.53       	0.14.3     	A Helm chart for deploying standalone greptimedb

安装 GreptimeDB 单机版​

基础安装​

使用默认配置快速安装:

helm upgrade --install greptimedb-standalone greptime/greptimedb-standalone -n default
Expected Output
Release "greptimedb-standalone" does not exist. Installing it now.
NAME: greptimedb-standalone
LAST DEPLOYED: Mon May 26 08:06:54 2025
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
***********************************************************************
 Welcome to use greptimedb-standalone
 Chart version: 0.1.53
 GreptimeDB Standalone version: 0.14.3
***********************************************************************

Installed components:
* greptimedb-standalone

The greptimedb-standalone is starting, use `kubectl get statefulset greptimedb-standalone -n default` to check its status.
kubectl get pod -n default
Expected Output
NAME                      READY   STATUS    RESTARTS   AGE
greptimedb-standalone-0   1/1     Running   0          40s

自定义安装​

创建自定义配置文件 values.yaml:

resources:
  requests:
    cpu: "2"
    memory: "4Gi"
  limits:
    cpu: "4"
    memory: "8Gi"

更多配置选项请参考 文档.

使用自定义配置安装:

helm upgrade --install greptimedb-standalone greptime/greptimedb-standalone \
  --values values.yaml \
  --namespace default
Expected Output
Release "greptimedb-standalone" has been upgraded. Happy Helming!
NAME: greptimedb-standalone

访问 GreptimeDB​

安装完成后，您可以通过以下方式访问 GreptimeDB:

kubectl port-forward svc/greptimedb-standalone 4002:4002 -n default > connections.out &
mysql -h 127.0.0.1 -P 4002
