GoldenGate教程FG089-OGG在云原生环境(EKS/GKE)部署实战

目录大纲

内容简介

本篇文章介绍OGG在云原生环境(EKS/GKE)的部署实战,包括容器化配置、Kubernetes部署、监控与管理等。风哥教程参考GoldenGate官方文档云原生部署指南。

Part01-基础概念与理论知识

1.1 云原生环境概述

云原生环境特点:

  • 容器化:使用Docker容器封装应用
  • 编排:使用Kubernetes进行容器编排
  • 弹性伸缩:根据负载自动调整资源
  • 服务网格:提供服务间通信和安全

1.2 OGG容器化部署原理

OGG容器化部署原理:

  • 将OGG安装到Docker容器中
  • 使用Kubernetes部署和管理容器
  • 配置持久卷存储OGG数据
  • 使用服务暴露OGG端口

Part02-生产环境规划与建议

2.1 系统硬件要求

风哥提示:云原生环境建议配置至少4个节点,每个节点8核CPU、32GB内存,以确保OGG的性能和可靠性。

2.2 网络与安全配置

网络要求:

  • 配置Kubernetes网络策略,允许OGG进程间通信
  • 设置安全组规则,开放必要的端口
  • 启用TLS/SSL加密,保护数据传输

Part03-生产环境项目实施方案

3.1 EKS部署配置

Dockerfile配置:

FROM oraclelinux:7

# 安装依赖包
RUN yum install -y unzip libaio gcc

# 创建OGG用户
RUN useradd -m -u 1000 ogg

# 复制OGG安装文件
COPY fbo_ggs_Linux_x64_shiphome.zip /home/ogg/

# 安装OGG
RUN su – ogg -c “unzip /home/ogg/fbo_ggs_Linux_x64_shiphome.zip”
RUN su – ogg -c “cd /home/ogg/fbo_ggs_Linux_x64_shiphome/Disk1 && ./runInstaller -silent -responseFile /home/ogg/response.rsp”

# 设置环境变量
ENV OGG_HOME=/home/ogg/ogg
ENV PATH=$PATH:$OGG_HOME

# 暴露端口
EXPOSE 7809

# 启动OGG Manager
CMD [“/home/ogg/ogg/ggsci”, “START”, “MGR”]

Kubernetes部署配置:

apiVersion: apps/v1
kind: Deployment
metadata:
name: ogg
namespace: fgedu
spec:
replicas: 1
selector:
matchLabels:
app: ogg
template:
metadata:
labels:
app: ogg
spec:
containers:
– name: ogg
image: ogg:21.3
ports:
– containerPort: 7809
volumeMounts:
– name: ogg-data
mountPath: /home/ogg/ogg/dirdat
– name: ogg-config
mountPath: /home/ogg/ogg/dirprm
volumes:
– name: ogg-data
persistentVolumeClaim:
claimName: ogg-data-pvc
– name: ogg-config
configMap:
name: ogg-config


apiVersion: v1
kind: Service
metadata:
name: ogg
namespace: fgedu
spec:
selector:
app: ogg
ports:
– port: 7809
targetPort: 7809
type: LoadBalancer

3.2 GKE部署配置

GKE部署步骤:

  1. 创建GKE集群
  2. 配置网络和存储
  3. 部署OGG容器
  4. 配置服务和Ingress

Part04-生产案例与实战讲解

4.1 EKS部署实战

# 创建EKS集群
$ eksctl create cluster –name ogg-cluster –region us-east-1 –nodegroup-name ogg-nodes –node-type m5.2xlarge –nodes 4

[ℹ] eksctl version 0.100.0
[ℹ] using region us-east-1
[ℹ] setting availability zones to [us-east-1a us-east-1b us-east-1c]
[ℹ] subnets for us-east-1a – public:192.168.0.0/19 private:192.168.32.0/19
[ℹ] subnets for us-east-1b – public:192.168.32.0/19 private:192.168.64.0/19
[ℹ] subnets for us-east-1c – public:192.168.64.0/19 private:192.168.96.0/19
[ℹ] nodegroup “ogg-nodes” will use “ami-0c55b159cbfafe1f0” [AmazonLinux2/1.21]
[ℹ] using Kubernetes version 1.21
[ℹ] creating EKS cluster “ogg-cluster” in “us-east-1”
[ℹ] will create 2 separate CloudFormation stacks for cluster itself and the initial nodegroup
[ℹ] if you encounter any issues, check CloudFormation console or try ‘eksctl utils describe-stacks –region=us-east-1 –cluster=ogg-cluster’
[ℹ] Kubernetes API endpoint access will use default of {publicAccess=true, privateAccess=false}
[ℹ] 2 sequential tasks: { create cluster control plane, create nodegroup }
[ℹ] building cluster stack “eksctl-ogg-cluster-cluster”
[ℹ] deploying stack “eksctl-ogg-cluster-cluster”
[ℹ] building nodegroup stack “eksctl-ogg-cluster-nodegroup-ogg-nodes”
[ℹ] deploying stack “eksctl-ogg-cluster-nodegroup-ogg-nodes”
[ℹ] waiting for the control plane to become ready
[ℹ] waiting for nodegroup “ogg-nodes” to become ready
[ℹ] nodegroup “ogg-nodes” has 4 node(s)
[ℹ] node “ip-192-168-10-100.ec2.internal” is ready
[ℹ] node “ip-192-168-20-200.ec2.internal” is ready
[ℹ] node “ip-192-168-30-300.ec2.internal” is ready
