[knutole]

Steps taken

• update package.json to latest

npm install -g npm-check-updates
ncu -u
rm node_modules/ -r
npm install

• install GLIBCXX_3.4.20 (due to mapnik.node error)

sudo apt-get install libstdc++6
# if that doesn't help:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test 
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y

• updated localhost config

TODO

• add this to pile/wu images
• push to docker hub
• make tests work on localhost
