1、下载地址
2、创建sentinel-dashboard目录，把sentinel-dashboard.jar移到该目录
3、新建Dockerfile

FROM adoptopenjdk/openjdk11
MAINTAINER liupg <11@qq.com>

COPY ./sentinel-dashboard-1.8.3.jar sentinel-dashboard.jar

EXPOSE 8718

CMD java ${JAVA_OPTS} -jar sentinel-dashboard.jar

4、打包镜像

docker build -t mom/sentinel-dashboard:latest .

5、打tag

docker tag mom/sentinel-dashboard:latest 10.10.10.131/mom/sentinel-dashboard:latest

docker push 10.10.10.131/mom/sentinel-dashboard:latest
