Installation

Install with Docker

docker run -p 8080:8080 — rm — name zeppelin apache/zeppelin:0.8.1

Set docker volume options to persist notebooks and logs like

docker run -p 8080:8080 — rm -v $PWD/logs:/logs -v $PWD/notebook:/notebook -e ZEPPELIN_LOG_DIR=’/logs’ -e ZEPPELIN_NOTEBOOK_DIR=’/notebook’ — name zeppelin apache/zeppelin:0.8.1

Install in a vagrant box

Setup base Vagrant Box

vagrant init ubuntu/trusty64
vagrant up
vagrant ssh

Update Operating System

sudo apt-get update -y
sudo apt-get upgrade -y

Install the Vagrant Key

The only way that all the vagrant commands will be able to communicate over ssh from the host machine to the guest server is if the guest server has this “insecure vagrant key” installed. It’s called “insecure” because essentially everyone has this same key and anyone can hack into everyone’s vagrant box if you use it.

mkdir -p /home/vagrant/.ssh
chmod 0700 /home/vagrant/.ssh
wget --no-check-certificate \
    https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub \
    -O /home/vagrant/.ssh/authorized_keys
chmod 0600 /home/vagrant/.ssh/authorized_keys
chown -R vagrant /home/vagrant/.ssh
