docker-postgis

A simple docker container that runs PostGIS

Note: We recommend using apt-cacher-ng to speed up package fetching - you should configure the host for it in the provided 71-apt-cacher-ng file.

Build

To build the image without apt-cacher do:

docker build -t kartoza/postgis git://github.com/timlinux/docker-postgis

To build with apt-cache do you need to clone this repo locally first and modify the contents of 71-apt-cacher-ng to match your cacher host. Then build using a local url instead of directly from github.

git clone git://github.com/timlinux/docker-postgis

Now edit 71-apt-cacher-ng then do:

docker build -t kartoza/postgis .

Run

To create a running container do:

sudo docker run --name "postgis" -p 2222:22 -p 25432:5432 -d -t kartoza/postgis

Connect via psql

To log in to your container do:

Connect with psql (make sure you first install postgresql client tools on your host / client):

psql -h localhost -U docker -p 25432 -l

Note: Default postgresql user is 'docker' with password 'docker'.

You can then go on to use any normal postgresql commands against the container.

Under ubuntu 14.04 the postgresql client can be installed like this:

sudo apt-get install postgresql-client-9.3

Storing data on the host rather than the container.

Docker volumes can be used to persist your data.

mkdir -p ~/postgres_data
docker run -d -v $HOME/postgres_data:/var/lib/postgresql kartoza/postgis`

You need to ensure the postgres_data directory has sufficinet permissions for the docker process to read / write it.

Connect via ssh

To log into your container do:

ssh root@localhost -p 2222

Default ssh password is 'postgis'
