Can not install package within docker debian:jessie

Question

I am tryint to install git within debian based container

postgres image is based on debian:jessie

dockerfile

FROM postgres:9.4


RUN apt-get -qq update

RUN apt-get install git-core
RUN apt-get install osm2pgsql

Both git and osm2pgsql can not be located

error

E: Unable to locate package git-core

What have I missed ?

Answer 1

I don't what's causing the 'unable to locate package' error, but your apt-get invocations are missing -y, which means you're going to get:

After this operation, 33.8 MB of additional disk space will be used.
Do you want to continue? [Y/n] Abort.
The command '/bin/sh -c apt-get install git-core' returned a non-zero code: 1

Otherwise, your Dockerfile worked just fine for me:
