Preliminary deployment preparation

The complete layout of the whole project

1. First, you can install (Docker integration) plug-in unit , If you have doubts about plug-ins, you can take a look IDEA Use Docker plug-in unit +（IDEA Can't find Docker integration terms of settlement ）

 2. Connect remotely linux, If for no other , Just for convenience

  After connection ：

 

Microservice coding

This is mainly about the deployment code of microservices, which is perfunctory

 application.yaml

spring:
  application:
    name: bank-accounts
server:
  port: 8881

pom.xml

<dependencies>
        <!--web-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- Super pit -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bootstrap</artifactId>
        </dependency>
    </dependencies>

effect ：

  that will do ！

Project package package

Wrong packing ：Failed to execute goal org.springframework.boot:spring-boot-maven-plugin

To write Dockerfile

FROM java:8
#  hold jar Add file to image , After adding and renaming 
ADD *.jar /accounts.jar
# Specify the port of the project 
CMD ["--server.port=8881"]
#  Exposed port 
EXPOSE 8881
#  perform java -jar The order of 
ENTRYPOINT ["java","-jar","/accounts.jar"]

The notes are written in great detail ,Dockerfile The file is used to build the image later

To write docker-compose.yaml file

version: "3.8"
networks:
  bank:
volumes:
  data:
services:
  bank-gateway:
    build:
      context: ./gateway
      dockerfile: Dockerfile
    container_name: gateway
    restart: always
    networks:
      - bank
    ports:
      - "8888:8888"

 

Upload to linux in ： 

Build a mirror image

Make sure there is no problem uploading the file

1.jar package

2.Dockerfile

3.docker-compose

 

  Docker Compose The orchestration tool downloads and loads the image , function ：

docker-compose up -d

  Wait for a while

 bank_bank-records It's working

  that will do ！
