Dockerfile issue with RPM

Question

I would like install auditserver on nodejs server , So my auditserver with rpm . it is working fine as a manual steps.

I write a Dockerfile like below.

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

while building the docker file I see below issue.

The problem is that you are not in the /opt directory when executing the rpm command (step 7). See this answer to find out why it happens. Quote:

Each time you RUN, you spawn a new container and therefore the pwd is '/'.

For how to fix it see this question. To summarize: you can use the WORKDIR dockerfile command or change this part:

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

to this:

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