Docker command fails during build, but succeeds while executed within running container

Question

the command :

docker build -t nginx-ubuntu . 

whith the Dockerfile below :

FROM ubuntu:12.10
RUN apt-get update
RUN apt-get -y install libpcre3 libssl-dev
RUN apt-get -y install libpcre3-dev
RUN apt-get -y install wget zip gcc
RUN wget http://nginx.org/download/nginx-1.4.1.tar.gz
RUN gunzip nginx-1.4.1.tar.gz
RUN tar -xf nginx-1.4.1.tar
RUN wget --no-check-certificate https://github.com/max-l/nginx_accept_language_module/archive/master.zip
RUN unzip master
RUN cd nginx-1.4.1
RUN ./configure --add-module=../nginx_accept_language_module-master --with-http_ssl_module --with-pcre=/lib/x86_64-linux-gnu --with-openssl=/usr/lib/x86_64-linux-gnu

Fails at the last line (./configure ...)

If I remove the last line and run a bash in the container, and execute the last line manually, it works.

I would expect that whatever command runs successfully within a container should work when the command is appended in the Dockerfile (prefixed by RUN)

am I missing something ?

The pwd is not persistent across RUN commands. You need to cd and configure within the same RUN.

This Dockerfile works fine:

FROM ubuntu:12.10
RUN apt-get update
RUN apt-get -y install libpcre3 libssl-dev
RUN apt-get -y install libpcre3-dev
RUN apt-get -y install wget zip gcc
RUN wget http://nginx.org/download/nginx-1.4.1.tar.gz
RUN gunzip nginx-1.4.1.tar.gz
RUN tar -xf nginx-1.4.1.tar
RUN wget --no-check-certificate https://github.com/max-l/nginx_accept_language_module/archive/master.zip
RUN unzip master
RUN cd nginx-1.4.1 && ./configure --add-module=../nginx_accept_language_module-master --with-http_ssl_module --with-pcre=/lib/x86_64-linux-gnu --with-openssl=/usr/lib/x86_64-linux-gnu
