Micro Services Architecture ------ DockerCompose project from installation to deployment

DockerCompose purpose: to simplify Docker start and stop processes, and the relationship between choreography Docker start the service with the service

DockerCompose的安装：curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

　　　　　　　　　　　chmod +x /usr/local/bin/docker-compose　　

　　　　　　　　　　　docker-compose version

1. curl -L https://github.com/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m`>/usr/local/bin/docker-compose

 

---

Write docker-compose.yml file, with the same format springboot written in the configuration file, but can not use the tab key to indent when writing yml file, do not believe you can try

Write a simple configuration tomcat startup configuration file

version: '3.1'
services: 
   tomcat: 
      restart: always
      image: tomcat
      container_name: tomcat
      ports: 
        - 8080:8080 

Start command: execution docker-compose up will be able to start running tomcat -d background in the current folder

Stop Command: docker-compose down the command stops and clear the vessel in order to start recording docker-compose form of a container

After a file vi:: set paste Paste command as it re-entered in the format i will be able to copy and paste AS

 

The following operations are in / usr / local / folder under the following operating, follow the linux folder specified operating range if you do not want to change elsewhere in the folder does not matter

Tomcat deployment

　　1.docker-compose.yml　　　　

version: '3.1'
services:
  tomcat:
    restart: always
    image: tomcat
    container_name: tomcat
    ports:
      - 8080:8080
    volumes:
      - ./webapps:/usr/local/tomcat/webapps
    environment:
      TZ: Asia/Shanghai

　　2. Run the docker-compose up -d 

　　　　At this point in the directory where you will generate a folder webapps, this folder is called data volumes, this position in the vessel     

/ Usr / local / tomcat / webapps position shared memory, which means that both the contents of the file folder are the same, so do not worry about the container is closed, the application data persistence problem

 

 

 　　　　Even if the container delete this data will still be retained

Deployment mysql

　　1.docker-compose.yml

version: '3.1'
services:
  db:
    # 目前 latest 版本为 MySQL8.x
    image: mysql
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: 123456
    command:
      --default-authentication-plugin=mysql_native_password
      --character-set-server=utf8mb4
      --collation-server=utf8mb4_general_ci
      --explicit_defaults_for_timestamp=true
      --lower_case_table_names=1
    ports:
      - 3306:3306
    volumes:
      - ./data:/var/lib/mysql
  # MySQL 的 Web 客户端
  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

　　2. Same as tomcat, docker creates a container with the data in the local shared memory space

 

  So far tomcat and mysql already deployed, as to how to deploy the project, I think you do not need me to say it?

Briefly about: First, the project lay in the war package extract to remove the extra generated under tomcat webapps folder files, the database initialization statements and historical data to perform the import, start two containers on it.
