k8s 制作镜像并推送到镜像仓库

1.制作镜像流程

2. 部署案例

2.1 导入数据库

• 创建数据库和账号密码

  mysql> create database if not exists java_demo default charset utf8 ;         # 创建数据库，默认utf8
  Query OK, 1 row affected (0.00 sec)
  
  
  mysql>  GRANT all on java_demo.* to 'java_demo'@'%' IDENTIFIED BY 'Aa@9953013';       #创建用户并授权
  Query OK, 0 rows affected, 1 warning (0.02 sec)
  
  mysql> flush privileges;                  #刷新
  Query OK, 0 rows affected (0.00 sec)
  
  

• 导入数据

  [root@localhost ~]# mysql -h127.0.0.1 -ujava_demo -p'Aa@9953013' < db/tables_ly_tomcat.sql
  mysql: [Warning] Using a password on the command line interface can be insecure.
  

• 修改连接数据库文件：src/main/resources/application.yml

  server:
    port: 8080
  spring:
    datasource:
      url: jdbc:mysql://192.168.0.230:3306/java_demo?characterEncoding=utf-8
      username: java_demo
      password: Aa@9953013
      driver-class-name: com.mysql.jdbc.Driver
    freemarker:
      allow-request-override: false
      cache: true
      check-template-location: true
      charset: UTF-8
      content-type: text/html; charset=utf-8
      expose-request-attributes: false
      expose-session-attributes: false
      expose-spring-macro-helpers: false
      suffix: .ftl
      template-loader-path:
        - classpath:/templates/
  
  

2.2 创建jenkins项目

2.2 进行项目编写

• 点击配置
  

• 源代码地址：https://github.com/tiaotiaodan/tomcat-java-demo

• 复制github源代码地址
  

• 这里是github地址，可以使用没有密码拉取
  

• java打包：mvn clean package -Dmaven.test.skip=true

• 编写dockerfile制作镜像
  

  cd $WORKSPACE  && mv target/*.war   target/ROOT.war  
  cat > Dockerfile <<EOF
  FROM tomcat
  MAINTAINER  shichao@scajy.cn
  
  COPY target/ROOT.war  /usr/local/tomcat/webapps/ROOT.war
  
  
  EOF
  docker build -t harbor.scajy.org/scajy/java:${tag} .
  
  docker login -uadmin -p'12345678' harbor.scajy.org
  docker push harbor.scajy.org/scajy/java:${tag}
