python容器化微服务器 微服务容器化部署

 

1、利用git工具从gitbub拉取代码

git clone https://github.com/xxxx/aaa-bbb.git

 

2、利用maven工具打包

mvn clean package

 

3、根据实际情况修改其配置文件application.yml和启动脚本

 

4、编写dockerfile文件

FROM java:8
COPY ./package/aaa-bbb-service-1.0.0.jar /aaa-bbb.jar
COPY ./scripts/start-aaa-bbb.sh /start-aaa-bbb.sh
COPY ./config/aaa-bbb/application.yml /application.yml
ENTRYPOINT ["sh","start-aaa-bbb.sh"]

 

5、根据dockerfile制作镜像

docker build -t aaa-bbb-server:1.0 -f dockerfile .

 

6、查看镜像

docker images | grep "aaa-bbb"

 

7、编写kubernetes的aaa-bbb.yaml文件

apiVersion: v1
kind: Service
metadata:
  name: aaabbb
  namespace: ab-server
spec:
  ports:
 ** - name: aaabbb
    port: 8080
    nodePort: 32001
  selector:
    app: aaabbb 
  type: NodePort 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: aaabbb
  namespace: ab-server
spec:
  selector:
    matchLabels:
      app: aaabbb
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: aaabbb
    spec:
      containers:
      - image: aaa-bbb-server:1.0
        imagePullPolicy: IfNotPresent
        name: aaabbb
        ports:
        - containerPort: 8080
          name: aaabbb

 

8、创建namespace

kubectl create ns ab-server

 

9、启动服务

kubectl apply/create -f aaa-bbb.yaml

 

10、查看aaa-bbb服务状态，Running表示正常

kubectl get pod -n ab-server

 

11、查看aaa-bbb服务资源信息和日志

kubectl descrile pod aaa-bbb-7d67789cbc-5qgzt -n ab-server

kubectl logs -f aaa-bbb-7d67789cbc-5qgzt -n ab-server
