apt-add-repository：在Dockerfile中找不到命令错误
我只是在我的terminal做了一个非常简单的docker文件，基本上我做了以下：
mkdir pgrouted cd pgrouted touch Dockerfile 现在我在nano编辑器中打开docker文件，并将以下命令添加到docker文件中：
FROM ubuntu MAINTAINER Gautam <gautamx07@yahoo.com> 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osm2pgrouting package RUN sudo apt-get install osm2pgrouting # Install workshop material (optional, but maybe slightly outdated) RUN sudo apt-get install pgrouting-workshop # For workshops at conferences and events: # Download and install from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 # login 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]"
整个Dockerfile可以在这里一目了然。
现在当我尝试构builddockerfile时，如下所示：
docker build -t gautam/pgrouted:v1 .
dockerfile运行，比我得到下面的错误：
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
有人可以告诉我为什么我得到这个错误？
apt-add-repository不在基本的Ubuntu镜像中。 你首先需要安装它。 尝试apt-get install software-properties-common
顺便说一句，你不需要在Dockerfile中使用sudo ，因为这些命令默认以root用户身份运行，除非你用USER命令切换到另一个用户。
