部署 Dubbo 应用到 Kubernetes + Docker 环境部署 Dubbo 应用到 Kubernetes + Docker 示例总体目标KubernetesZookeeperDubbo-admin + ZookeeperProducer + Zookeeper 与 Consumer + Zookeeper基本流程与工作原理
详细步骤创建命名空间
kubectl create ns dubbo-demo
zookeeper获取图表
helm repo add bitnami https://charts.bitnami.com/bitnami
安装 zookeeper
helm install zookeeper bitnami/zookeeper --set persistence.enabled=false -n dubbo-demo
查看 zookeeper
kubectl get pods -n dubbo-demo
dubbo-admin克隆项目到本地
git clone https://github.com/apache/dubbo-admin.git && cd /dubbo-admin/deploy/k8s
创建服务
kubectl apply -f ./ -n dubbo-demo
启动服务
kubectl --namespace dubbo-demo port-forward service/dubbo-admin 38080:38080

切换到服务示例
cd && cd dubbo-samples/1-basic/dubbo-samples-spring-boot
打包编译
mvn clean package
Producer切换至目标服务
cd dubbo-samples-spring-boot-provider/target
构建镜像
cat <
FROM openjdk:8-jdk-alpine
ADD dubbo-samples-spring-boot-provider-1.0-SNAPSHOT.jar /app.jar
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/urandom", "-jar", "/app.jar"]
EOF
编译镜像
docker build --no-cache -t dubbo-springboot-provider:alpine .
导入服务
cat <
apiVersion: v1
kind: Pod
metadata:
name: dubbo-springboot-provider
namespace: dubbo-demo
spec:
containers:
- name: provider
image: dubbo-springboot-provider:alpine
EOF
创建服务
kubectl create -f provider.yaml
Consumer切换至目标服务
cd dubbo-samples-spring-boot-consumer/target
构建镜像
cat <
FROM openjdk:8-jdk-alpine
ADD dubbo-samples-spring-boot-consumer-1.0-SNAPSHOT.jar /app.jar
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/urandom", "-jar", "/app.jar"]
