apt-add-repository: command not found error in Dockerfile

I just made a very simple Docker file in my terminal, basically I did the following:

mkdir pgrouted
cd pgrouted
touch Dockerfile

Now I open the Docker file in the nano editor, and I add the following commands to the Docker file:

FROM ubuntu

MAINTAINER Gautam <[email protected]>

LABEL Description="pgrouting excercise" Vendor="skanatek" Version="1.0"

ENV BBOX="-122.8,45.4,-122.5,45.6"

# Add pgRouting launchpad repository
RUN sudo apt-add-repository -y ppa:ubuntugis/ppa
RUN sudo apt-add-repository -y ppa:georepublic/pgrouting
RUN sudo apt-get update

# Install pgRouting package (for Ubuntu 14.04)
RUN sudo apt-get install postgresql-9.3-pgrouting

# Install osm2pgrouting package
RUN sudo apt-get install osm2pgrouting

# Install workshop material (optional, but maybe slightly outdated)
RUN sudo apt-get install pgrouting-workshop

# For workshops at conferences and events:
# Download and install from http://trac.osgeo.org/osgeo/wiki/Live_GIS_Workshop_Install
RUN wget --no-check-certificate https://launchpad.net/~georepublic/+archive/pgrouting/+files/pgrouting-workshop_2.0.6-ppa1_all.deb

RUN sudo dpkg -i pgrouting-workshop_2.0.6-ppa1_all.deb

# Review: Not sure weather this should be in the dockerfile
RUN cp -R /usr/share/pgrouting/workshop ~/Desktop/pgrouting-workshop

# Log in as user "user"
RUN psql -U postgres

# Create routing database
RUN CREATE DATABASE routing;

# Add PostGIS functions
RUN CREATE EXTENSION postgis;

# Add pgRouting core functions
CREATE EXTENSION pgrouting;

# Download using Overpass XAPI (larger extracts possible than with default OSM API)
wget --progress=dot:mega -O "sampledata.osm" "http://www.overpass-api.de/api/xapi?*[bbox=${BBOX}][@meta]"

The entire Dockerfile can be see HERE at a glance.

Now when I try to build the Dockerfile, like so:

docker build -t gautam/pgrouted:v1 .

The Dockerfile runs and then I get the below error:

Step 4 : RUN sudo apt-add-repository -y ppa:ubuntugis/ppa
 ---> Running in c93c3c5fd5e8
sudo: apt-add-repository: command not found
The command '/bin/sh -c sudo apt-add-repository -y ppa:ubuntugis/ppa' returned a non-zero code: 1

Why am I getting this error?

Solution 1:

apt-add-repository is just not in the base Ubuntu image. You'll first need to install it. try apt-get install software-properties-common

By the way, you don't need to use sudo in the Dockerfile because the commands run as root by default unless you change to another user with the USER command.

Solution 2:

Add these lines before running apt-add-repository command

RUN apt-get update && \
    apt-get install -y software-properties-common && \
    rm -rf /var/lib/apt/lists/*
