一、準備工作：
1）安裝好docker，並安裝私有倉庫;
2）使用docker部署jenkins;
3）部署好kubernetes;
二、使用jenkins的maven進行打包，並上傳到docker私有倉庫，腳本如下：
push_docker_registry.sh
#!/bin/sh
echo -----------------------------------------parameter define -----------------------------------------
project_name=oss-gateway #工程名字，需配置
tag=$BUILD_TAG #鏡像標籤，自動生成，無需手動配置
sudo docker rmi aigpu.xxxxxxx.com:30143/library/$project_name
set -e
echo $(pwd)
echo "FROM java:8
VOLUME /tmp
ADD $project_name/target/*.jar app.jar
ENTRYPOINT [\"java\",\"-Djava.security.egd=file:/dev/./urandom\",\"-jar\",\"/app.jar\"]" > Dockerfile
echo -------------build image and push it to harbor ---------------------
sudo docker build -t aigpu.xxxxx.com:30143/library/$project_name:$tag -f Dockerfile --rm=true .
sudo docker login -u admin -p Cd12345 aigpu.xxxxx.com:30143
sudo docker push aigpu.xxxxxx.com:30143/library/$project_name:$tag
echo images_url=aigpu.xxxxxxx.com:30143/library/$project_name:$tag > $project_name.txt
echo This is imagesUrl
echo '********************************************************************************************************************'
echo
echo aigpu.xxxxxxx.com:30143/library/$project_name:$tag
echo
echo '********************************************************************************************************************'
三、從私有倉庫拉包部署到Kubernetes上（使用堡壘機發布）。
實現原理，生成編排文件，存放到master節點上使用kubectl apply -f 進行發佈
sendfileto_k8s.sh
#!/bin/bash
echo -----------------------------------------parameter define -----------------------------------------
project_name=oss-gateway #工程名稱，唯一，需配置
port=8888 #容器端口，注意與配置選擇的profile對應，需配置
profile=dev #生效的配置文件（spring.profiles.active），需配置
podNum=1 #需要啓動節點數量，需配置
logPath=/var/log/xxxxxx/oss-gateway #日誌路徑，需配置
tag=$BUILD_TAG #鏡像標籤，自動生成，無需手動配置
