docker-打包釋出指令碼
阿新 • • 發佈：2021-11-03
思路：直接將jar包放到某個資料夾，通過指令碼實現打包image，併發布
#目錄下檔案顯示jar包、Dockerfile檔案、打包啟動指令碼
[root@localhost mkpackge1]# ls
chinapopin-department-web-1.0-SNAPSHOT.jar Dockerfile qd.sh
#啟動指令碼內容
[root@localhost mkpackge1]# more qd.sh
#!/bin/bash
dir=$(cd $(dirname $0);pwd)
i=${1-image_name}
#delete pod
docker rm -f $i
#delete image
docker rmi -f $i:latest
#makpage
cd $dir
docker build -t $i:latest .
#start pod
docker run --name $i --net=host -d $i:latest
#Dockerfile內容---注意需要修改jar的埠7002改成直接程式的
[root@localhost mkpackge1]# more Dockerfile
FROM wukc/openjdk:8-jdk-alpine
COPY *.jar app.jar
EXPOSE 7002
ENTRYPOINT ["java","-jar","/app.jar"]
啟動方式sh qd.sh deploy_name
