ADD failed: stat /var/lib/docker/tmp/docker-builderXXXXXX: no such file or directory

 

以为是centos安装docker的问题，最后发现是工程的pom.xml 和Dockerfile配置不一致

ADD user-server-0.0.1-SNAPSHOT.jar app.jar  要和pom的<artifactId>user-server</artifactId>

保持名字一样，不然maven打出来的包，docker找不到。

以下是我可行的配置：

 

Dockerfile

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD user-server-0.0.1-SNAPSHOT.jar app.jar
#RUN bash -c 'touch /app.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
EXPOSE 8761
