Question

我想在nodejs服务器上安装auditserver，所以我的auditserver用rpm。它作为手动步骤正常工作。

我写了一个如下的Dockerfile。

FROM    centos:centos6

# Enable EPEL for Node.js
RUN rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

# Install Node.js and npm
RUN yum install -y npm

# ADD rpm into container
ADD auditserver-1-1.x86_64.rpm /opt/

RUN mkdir -p /opt/auditserver

RUN cd /opt

RUN rpm -Uvh auditserver-1-1.x86_64.rpm

# cd to auditserver
RUN cd /opt/auditserver

# Install app dependencies
RUN  npm install
# start auditserver
RUN node server

EXPOSE  8080

在构建docker文件时我看到了下面的问题。

可以帮助解决这个问题，使其成为完美的Dockerfile。谢谢。

问题是您在执行/opt命令时不在rpm目录中（步骤7）。请参阅this answer以了解其发生的原因。引用：

每次运行时，都会产生一个新的容器，因此pwd是＆＃39; /＆＃39;。

有关如何解决问题，请参阅this question。总结一下：您可以使用WORKDIR dockerfile命令或更改此部分：

RUN cd /opt
RUN rpm -Uvh auditserver-1-1.x86_64.rpm

到此：

RUN cd /opt && rpm -Uvh auditserver-1-1.x86_64.rpm
