Building a vector tile server

Now that Open Layers fully supports vector layers, we're looking at the practicality of running a vector tile server for our projects. Starting from this docker example, I created a script which I can run on a standard Debian Stretch install to create a working tile server:


#This is to be run on a standard Debian Stretch install.

#Install core stuff
apt-get update && DEBIAN_FRONTEND=noninteractive apt-get -y install apt-transport-https curl unzip build-essential python libcairo2-dev libprotobuf-dev xvfb 

#Temporarily use a specific source for the exact nodejs version we need.
echo "deb jessie main" >> /etc/apt/sources.list.d/nodejs.list
echo "deb-src jessie main" >> /etc/apt/sources.list.d/nodejs.list

#Install it.
apt-get -qq update && DEBIAN_FRONTEND=noninteractive apt-get -y --allow-unauthenticated install nodejs 

#Now remove the source.
rm /etc/apt/sources.list.d/nodejs.list
apt-get clean

#Added these in order to get the npm install to run properly. 
#The problem was building canvas.
apt-get -y install libjpeg62-turbo-dev libpango1.0-dev libgif-dev g++

#Create directory for tileserver application.
mkdir -p /usr/src/app

#Get the Klokantech code for the server.
cd /usr/src/app 
curl -L -o
cp -r tileserver-gl-master/* ./
rm -rf tileserver-gl-master

#Install the node stuff
npm install --production

#Set environment variable
echo NODE_ENV=\"production\" >> /etc/environment

#Create the folder for the mbtiles files (you'll need to supply these later).
mkdir /data

#In case other servers are installed and running, stop them.
systemctl stop apache2 mysql
systemctl disable apache2 mysql

echo "Now put your mbtiles files into the /data folder, and run /usr/src/app/"
#Start the tileserver on port 80.

This could form the basis for a VM-based tileserver for our projects, including the Confederation Debates; running a server for all of Canada is quite practical due to the efficiency of the vector format.
