Install pip in docker

Question

I'm not able to install pip in Docker.

Here's my Dockerfile:

FROM ubuntu:14.04  # Install dependencies RUN apt-get update -y RUN apt-get install -y git curl apache2 php5 libapache2-mod-php5 php5-mcrypt php5-mysql python3.4 python-pip 

When building, I get:

Sending build context to Docker daemon 109.6 kB Step 1 : FROM ubuntu:14.04  ---> b549a9959a66 Step 2 : RUN apt-get update -y  ---> Using cache  ---> 84577471562c Step 3 : RUN apt-get install -y git curl apache2 php5 libapache2-mod-php5 php5-mcrypt php5-mysql python3.4 python-pip  ---> Running in 49252a6d0eb1 Reading package lists...

Having read this answer, I tried adding the line RUN "sh" "-c" "echo nameserver 8.8.8.8 >> /etc/resolv.conf" - the error this time is:

... ... Reading state information... E: Unable to locate package php5-mcrypt E: Unable to locate package python-pip The command '/bin/sh -c apt-get install -y git curl apache2 php5 libapache2-mod-php5 php5-mcrypt php5-mysql python3.4 python-pip' returned a non-zero code: 100 

What am I doing wrong? I've seen some claims that I should try a different version of Ubuntu, but switching to 13.1 didn't change anything.

While T. Arboreus's answer might fix the issues with resolving 'archive.ubuntu.com', I think the last error you're getting says that it doesn't know about the packages php5-mcrypt and python-pip. Nevertheless, the reduced Dockerfile of you with just these two packages worked for me (using Debian 8.4 and Docker 1.11.0), but I'm not quite sure if that could be the case because my host system is different than yours.

FROM ubuntu:14.04  # Install dependencies RUN apt-get update && apt-get install -y \     php5-mcrypt \     python-pip 

However, according to this answer you should think about installing the python3-pip package instead of the python-pip package when using Python 3.x.

Furthermore, to make the php5-mcrypt package installation working, you might want to add the universe repository like it's shown right here. I had trouble with the add-apt-repository command missing in the Ubuntu Docker image so I installed the package software-properties-common at first to make the command available.

Splitting up the statements and putting apt-get update and apt-get install into one RUN command is also recommended here.

Oh and by the way, you actually don't need the -y flag at apt-get update because there is nothing that has to be confirmed automatically.

Finally:

FROM ubuntu:14.04  # Install dependencies RUN apt-get update && apt-get install -y \     software-properties-common RUN add-apt-repository universe RUN apt-get update && apt-get install -y \     apache2 \     curl \     git \     libapache2-mod-php5 \     php5 \     php5-mcrypt \     php5-mysql \     python3.4 \     python3-pip 

Remark: The used versions (e.g. of Ubuntu) might be outdated in the future.
