Docker没有复制解压缩的文件

Question

今天发现一个奇怪的问题，在docker解压缩指令之后，当我试图复制解压缩的文件时，COPY失败了。在本地，这很好，但在gitlab管道中失败了。

Dockerfile

FROM caapim/gateway:10.0.00
ARG API_NAME=gateway
USER root
# Install awscli
RUN yum -y update && 
yum clean all &&  
yum -y install awscli
# Install newrelic
RUN mkdir -p /opt/newrelic/extensions && 
curl -O https://download.newrelic.com/newrelic/java-agent/newrelic-agent/current/newrelic-java.zip && 
unzip newrelic-java.zip
#Copy newrelic specific files in /opt/newrleic/newrelic.jar
RUN ls newrelic/
#COPY ./newrelic/newrelic.jar /opt/newrelic/newrelic.jar
ADD ./newrelic/newrelic.jar /opt/newrelic/newrelic.jar

注意：我删除了一些指令，并为RCA添加了一些。
