Gitlab集成jenkins及docker自动化部署教程

能实现提交代码到gitlab后，我们只需要合并代码到指定分支就可以上Jenkins自动拉取最新代码并重新构建部署

1、登录Jenkins点击如下加号新增视图

2、gitlab配置Jenkins成员，供Jenkins使用

3、Jenkins配置选择如下选项

代码如下：

REPOSITORY=192.168.1.240:5000/project_name/service_name:test1

cat > Dockerfile << EOF

#基础镜像，如果本地没有，会从远程仓库拉取。

FROM openjdk:8

 

#声明了容器应该打开的端口并没有实际上将它打开

EXPOSE 10011

 

# 将jar包添加到容器中并更名为app.jar

ADD target/service_name-2.0.0-SNAPSHOT.jar app.jar

 

 

#指定容器启动时要执行的命令，但如果存在CMD指令，CMD中的参数会被附加到ENTRYPOINT指令的后面

ENTRYPOINT ["java","-Xms512m","-Xmx1024m","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar", "--spring.profiles.active=test1"]

EOF

# 构建镜像

docker build -t $REPOSITORY .

docker login -u admin -p 123456 192.168.1.240:5000

# 上传镜像

docker push $REPOSITORY

Docker环境部署代码如下：

REPOSITORY=192.168.1.240:5000/project_name/service_name:test1

docker login -u admin -p 123456 192.168.1.240:5000

docker pull $REPOSITORY

docker rmi $(docker images | grep "none" | awk '{print $3}')

 

mkdir -p /usr/local/docker/project_name/service_name

cd /usr/local/docker/project_name/service_name

cat > docker-compose.yml<< EOF

version: "3.7"

services:

  kxkd-push-service:

    image: $REPOSITORY

    restart: always

    container_name: service_name

    logging:

      driver: "json-file"

      options:

        max-size: "1G"

    environment:

      - TZ=Asia/Shanghai

    ports:

      - "10011:10011"

    volumes:

      - "/usr/local/docker/project_name/service_name/logs:/logs"

      - "/usr/local/docker/project_name/service_name/sensors:/usr/local/docker/kxkd"

      - "/usr/local/docker/project_name/service_name/fonts:/usr/local/openjdk-8/jre/lib/fonts"

EOF

docker-compose down

docker-compose up -d
