镜像制作

基础镜像

这是一个同时包含jdk17和nginx环境的基础镜像

FROM bellsoft/liberica-openjdk-debian:17-cds
RUN apt install nginx -y

docker build -t bellsoft/liberica-openjdk-debian-nginx:17-cds .

镜像分层构建

FROM bellsoft/liberica-openjdk-debian:17-cds as builder
WORKDIR application
ADD target/*.jar app.jar
RUN java -Djarmode=layertools -jar app.jar extract

FROM nginx:1.24.0 as builder1
ADD front/nginx/ /etc/nginx/
ADD front/html/web /usr/share/nginx/html/web
ADD front/html/app /usr/share/nginx/html/app

# 正式构建镜像
FROM bellsoft/liberica-openjdk-debian-nginx:17-cds
ENV TZ=Asia/Shanghai
WORKDIR application
EXPOSE 8080
ENV PARAMS="-Dspring.profiles.active=dev -Dlogging.level.org.hibernate.SQL=info"

RUN chmod +x /start.sh
ENTRYPOINT ["/start.sh"]
