Golem

Run apps in automatically provisioned virtual machines or docker containers.

• includes docker (inside an Ubuntu VM)
• powered by Vagrant, VirtualBox and Ubuntu 14.04 LTS
• takes care of folder sync and port forwarding

Requirements

• Windows, Mac OS X, Linux, or Solaris
• vagrant
• virtualbox

Note: golem init will check these requirements for you (and on OSX it will try to install them using brew and brew cask).

Install

npm i -g golem

now you can create a global golem for your user:

golem init --global

or create one for the current folder (./.golem):

golem init

Updates

You can keep golem up-to-date by running:

# download updates, reload and re-provision will happen if necessary
golem update

Usage

Once a golem is ready, you can start running commands on the golem virtual machine

# Summon your Golem! (spin up the vm)
golem summon

golem do pwd
# prints the synced guest folder (created on the VM)

# golem will run the command (after "do" word) in the vm
# first time you run "golem do" on a directory, a synced folder is created to
# mirror cwd on guest vm, then commands are executed in that guest folder
golem do ls
# will list the files in current host folder, shared into the VM

or you can just open an ssh session starting a the synced folder with:

golem do

To recreate your golem from scratch, you can always:

# remove the VM
golem destroy
# re-create (and re-provision)
golem summon

Docker

you can run docker commands with:

golem docker run ubuntu echo "hi, from docker"
# note: "golem docker" is just a shortcut to "golem do sudo docker"

if you like docker-compose a shortcut is provided to:

golem docker-compose

Port Forwarding

In some cases you want to forward ports in the VM to your host machine (eg. from you docker containers)

# expose port 80 in the VM as 8080 in your host machine, 443 as 8443
golem expose 80:8080,443:8443
# list exposed ports
golem expose list
# remove all exposed ports
golem expose clear
