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

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 ?

One solution is to run multiple commands, as many as you want, in a single RUN with &&:

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

or include a backslash, && \ if wanting to continue on the next line:

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

Another way of doing this using the \ operator to start a new line and proceed with an additional command

Example

RUN cd /Desktop \ 
    cd Work \   
    pwd

When I called wget or tar with RUN I needed to specify a path, it looks like ADD is the correct approach if you want to use WORKDIR as it's path instead. So either of the below resolved my issue.

RUN 

RUN wget http://nginx.org/download/nginx-1.4.1.tar.gz -P ~/directory
RUN tar -zxf ~/directory/nginx-1.4.1.tar.gz -C ~/directory

or

ADD

WORKDIR ~/directory
ADD http://nginx.org/download/nginx-1.4.1.tar.gz nginx-1.4.1.tar.gz
RUN tar -zxf nginx-1.4.1.tar.gz

The second approach prevented me from needing to install wget in the container.

As an alternative to @creak's answer, you can change the default working directory in a Dockerfile with the WORKDIR command:

FROM ubuntu:12.10
# Run update & install together so that the docker cache doesn't
# contain an out-of-date APT cache (leading to 404's when installing
# packages)
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get -y install libpcre3 libssl-dev libpcre3-dev wget zip gcc
ADD http://nginx.org/download/nginx-1.4.1.tar.gz nginx-1.4.1.tar.gz
RUN tar -zxf nginx-1.4.1.tar.gz
RUN wget --no-check-certificate https://github.com/max-l/nginx_accept_language_module/archive/master.zip
RUN unzip master
WORKDIR 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

This also affects the default directory when you use docker run (overridden by the -w switch).

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
