VagrantでJupyter Labとmonetdbをインストールした仮想マシン(Debian Stretch/9.3)を構築する

Jupyter Labでインタラクティブなコンピューティング環境を提供する事ができます。

仮想マシンの構築方法

以下のVagrantfileで、Jupyter Labとmonetdbをインストールした仮想マシン(Debian Stretch/9.3)を構築できます。

Vagrantfile

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "bento/debian-9.3"
  config.vm.hostname = "db93jupyterlabmonetdb"
  config.vm.provider :virtualbox do |vbox|
     vbox.name = "db93jupyterlabmonetdb"
     vbox.cpus = 2
     vbox.memory = 2048
     vbox.customize ["modifyvm", :id, "--nicpromisc2","allow-all"]
  end
config.vm.network "private_network", ip: "192.168.55.107", :netmask => "255.255.255.0"
config.vm.network "public_network", ip:"192.168.1.107", :netmask => "255.255.255.0"
  config.vm.provision "shell", inline: <<-SHELL

動作確認用コード

以下のサンプルコードで動作を確認することができます。

import pymonetdb

con = pymonetdb.connect(username="monetdb", password="monetdb", hostname="localhost", database="testdb")

try:
  cur= con.cursor()
  sql = "select message_id, message from test1"
  cur.execute(sql)

  for row in cur.fetchall():
    print(row)

except pymonetdb.Error as er:
    print('pymonetdb.Error:', er)
cur.close
con.close
