Question

我想运行这个Dockerfile应用程序：

FROM java:8-jre
ADD config/ /deploy/
COPY ./meta.std.1.0.1.jar /deploy/
CMD chmod +x ./deploy/meta.std.1.0.1.jar
CMD ["java","-jar","/deploy/meta.std.1.0.1.jar","metastore","spring.config.location=./config/metadata-server.yml"]
EXPOSE 3011

在运行时，它没有读取metadata-server.yml值？这是正确的方法吗？

Answer 1

我认为你把错误的路径设置为metadata-server.yml

＆＃34; spring.config.location = /配置/元数据server.yml＆＃34;

我认为之后：

ADD config / / deploy /

metadata-server.yml的路径应为：

＆＃34; spring.config.location = /部署/配置/元数据server.yml＆＃34;

Answer 2

使用

FROM java:8-jre
ADD config/ /deploy/
COPY ./meta.std.1.0.1.jar /deploy/
CMD chmod +x ./deploy/meta.std.1.0.1.jar
CMD ["java","-jar","/deploy/meta.std.1.0.1.jar","metastore","--spring.config.location=classpath:file:/deploy/metadata-server.yml"]
EXPOSE 3011

<强>更新

或者更好的尝试这个

FROM alpine:edge

VOLUME /tmp

RUN apk --no-cache upgrade && apk --no-cache add openjdk8-jre

ADD config/ /deploy/
COPY ./meta.std.1.0.1.jar /deploy/
ADD /YOUR/CONFIG/metadata-server.yml /deploy/metadata-server.yml

EXPOSE 3011

ENTRYPOINT ["java" ,"-Djava.security.egd=file:/dev/./urandom --spring.config.location=classpath:file:/deploy/metadata-server.yml","-jar","/deploy/meta.std.1.0.1.jar"]
