我刚在终端上制作了一个非常简单的Docker文件,基本上我做了以下工作:
mkdir pgrouted
cd pgrouted
touch Dockerfile
现在我在nano编辑器中打开Docker文件,然后将以下命令添加到Docker文件中:
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# Install workshop material (optional, but maybe slightly outdated)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]"
整个Dockerfile可以一目了然地看到HERE。
现在,当我尝试构建Dockerfile时,如下所示:
docker build -t gautam/pgrouted:v1 .
Dockerfile运行然后我得到以下错误:
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
为什么我收到此错误?
apt-add-repository不在基本的Ubuntu映像中。您首先需要安装它。试试apt-get install software-properties-common
顺便说一句,您不需要在Dockerfile中使用sudo,因为默认情况下命令以root身份运行,除非您使用USER
命令更改为其他用户。
在运行apt-add-repository
命令之前添加这些行
RUN apt-get update
RUN apt-get install -y software-properties-common
