- Dockerfile 文件 构建镜像:
#基础镜像,如果本地仓库没有,会从远程仓库拉取 openjdk:8 FROM openjdk:8 #暴露端口 EXPOSE 9301 #容器中创建目录 RUN mkdir -p /usr/local/java #编译后的jar包copy到容器中创建到目录内 ../../realize-gateway COPY realize-auth.jar /usr/local/java/realize-auth.jar #指定容器时区 RUN rm -f /etc/localtime \ && ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \ && echo "Asia/Shanghai" > /etc/timezone #指定容器启动时要执行的命令 ENTRYPOINT ["java","-jar","-Dspring.profiles.active=server","/usr/local/java/realize-auth.jar"]
- k8s realize-auth.yaml 文件:
