微服务小范围发布影响小

1 看下项目结构，首先要有dockerfile,
FROM git.we3tu.com:5000/tomcatmaven:latest
RUN apk --update add wget
RUN mkdir -p /usr/src/app
RUN mkdir -p /usr/scripts
RUN mkdir -p /www
WORKDIR /usr/src/app
COPY . /usr/src/app
RUN unzip /usr/src/app/target/visa.war -d /opt/tomcat/webapps/ROOT
RUN cp /usr/src/app/start.sh /usr/scripts
RUN rm -rf /usr/src/app

ENTRYPOINT ["/bin/sh","/usr/scripts/start.sh"]

2 关于应用的配置文件用变量传递下载到测试环境或生产环境
vim start.sh
#! /bin/sh
wget http://$DOMAIN_ENV.config.we3tu.com/$PROJECTNAME/dev/application.properties -O /opt/tomcat/webapps/ROOT/WEB-INF/classes/dev/application.properties 测试环境配置文件路径
wget http://$DOMAIN_ENV.config.we3tu.com/$PROJECTNAME/pro/application.properties -O /opt/tomcat/webapps/ROOT/WEB-INF/classes/pro/application.properties 生产环境配置文件路径
wget http://$DOMAIN_ENV.config.we3tu.com/$PROJECTNAME/applicationContext.xml -O /opt/tomcat/webapps/ROOT/WEB-INF/classes/applicationContext.xml
/opt/tomcat/bin/catalina.sh run

  4 部署的路径怎么部署：
  vim deploy.test.yml
  version: ‘3‘
  services:
  visa_service_test:
  image: git.we3tu.com:5000/$PROJECT_NAME:$CI_COMMIT_REF_NAME
  environment:
  • "DOMAIN_ENV=test"
  • "PROJECTNAME=visa"
  • "QUARTZ_ENV=noquartz"
    logging:
    driver: syslog
    options:
    syslog-address: "tcp://x.x.x.x:5514"
    tag: $PROJECT_NAME
    ports:
  • 8021:8080
    deploy:
    replicas: 1
    update_config:
    parallelism: 1
    delay: 10s
    restart_policy:
    condition: any
    networks:
  • docker-cy-test
    networks:
    docker-cy-test:
    external: true

5 vim deploy.prod.yml
version: ‘3‘
services:
visa_service:
image: git.we3tu.com:5000/$PROJECT_NAME:$CI_COMMIT_REF_NAME
environment:

• "DOMAIN_ENV=prod"
• "PROJECTNAME=visa"
• "QUARTZ_ENV=noquartz"
  logging:
  driver: json-file
  ports:
• 8021:8080
  deploy:
  replicas: 2
  update_config:
  parallelism: 1
  delay: 10s
  restart_policy:
  condition: any
  max_attempts: 10
  networks:
• prod-net
  networks:
