docker 使用Dockerfile更新jenkins镜像 docker-compose 更新镜像

docker-compose镜像版本动态控制

提取.env文件进行配置通用环境变量

# 当前机器用户的home路径
HOST_HOME=/home/guimu
# 上传文件临时路径
TMP_DATA_PATH=${HOST_HOME}/tempdata/
# media的home路径
MEDIA_HOME=/media
# 挂载的mysql的data路径
MYSQL_DATA_PATH=${HOST_HOME}/mysql/data
# mysql配置文件
MYSQL_CONF=${HOST_HOME}/mysql/my.cnf
#redis数据
REDIS_DATA_PATH=${HOST_HOME}/redis/data
#redis配置文件
REDIS_CONFIG=${HOST_HOME}/redis/redis.conf
# geoserver路径
GEO_SERVER_HOME=${HOST_HOME}/geoserver
# mysql数据库的用户名
DB_USER=root
# mysql数据库的密码
DB_PASSWORD=password
# mysql数据库的host, 一般不用修改,除非docker-compose中的mysql容器名修改才进行修改
DB_HOST=das-mysql
# 当前机器的ip(一般用外网能访问的ip)
HOST_IP=localhost
# 用于测试打包新版本服务镜像, 需要打包新镜像版本时使用
VERSION=latest
# 图像雷达服务日志路径
IMG_RADAR_LOG_PATH=${HOST_HOME}/img_radar_log

# 修改.env文件中的version配置打包对应的版本镜像, 指定文件docker-compose-dev.yml构建dev的镜像

docker-compose -f docker-compose-dev.yml up --build -d

推送构建的镜像到远程仓库

# 首先需要登录对应的远程仓库, 输入指定的账号密码

docker login

编写对应的推送脚本pushImage.sh:

#!/bin/bash
version=$1

commands="docker push kven/das-workflow-service:${version};
docker push kven/das-ui-service:${version};
docker push kven/das-security-service:${version};
docker push kven/das-data-raw-service:${version};
docker push kven/das-data-gis-service:${version};
docker push kven/das-data-processed-service:${version};
docker push kven/api-gateway-zuul:${version};
docker push kven/service-registry:${version};"

bash -c "$commands"

# 设定可执行权限

chmod +x pushImage.sh

# 推送指定的版本:

# ./pushImage.sh 版本号

./pushImage.sh latest

配置Jenkins

新建工程

 配置工程名称, 选择freestyle project,点击确定

 支持参数化构建

 通过shell构建

 在对应的构建服务器上编写restart.sh脚本:

#!/bin/bash
# 切换到对应的工程目录
cd /home/guimu/das-docker/guimu-micro-service-platform-internal
# 更新代码
svn up
# 打包
mvn package -DskipTest
# 关闭原有的容器
docker-compose -f docker-compose-dev.yml down
# 构建新的容器并启动
docker-compose -f docker-compose-dev.yml up --build -d

# 添加可执行权限

chmod +x restart.sh

在前一步中的Jenkins添加的shell中编写脚本:

#!/bin/sh
# 切换到工程的工作空间
cd /home/guimu/das-docker
# 根据Jenkins的构建参数version动态替换.env文件中对应的版本号
sed -i "s/VERSION=\(.*\)/VERSION=${version}/g" /home/guimu/das-docker/guimu-micro-service-platform-internal/.env
# 重启并构建新版本的容器镜像
./restart.sh
# 推送对应的版本镜像
./pushImage.sh $version
