# Bubble Vagrantfile
# ==================
# Running `vagrant up` will create a full Bubble development environment including all
# dependencies, and build all the code and website. You'll be ready to run a local
# launcher or do dev work on the Bubble codebase.
#
# After a box is launched, use `vagrant ssh` to log in.
#   - the code is in ${HOME}/bubble
#   - API environment file is ${HOME}/.bubble.env
#   - start the API server (local launcher) with run.sh
#   - access the webapp at http://127.0.0.1:${BUBBLE_PORT}/
#
# There are a few environment variables that determine how the box is initialized,
# described below.
#
# ## Environment Variables
#
# ### LETSENCRYPT_EMAIL
# If you specify the LETSENCRYPT_EMAIL environment variable, then `vagrant up` will also
# start a Local Launcher (see docs/local-launcher.md) which is your starting point for
# launching new Bubbles. You can always change this later by editing the `~/.bubble.env`
# file after the Vagrant box is setup.
#
# ### BUBBLE_PORT
# By default, Bubble will listen on port 8090.
# If something else is already using that port on your computer, `vagrant up` will fail.
# Set the `BUBBLE_PORT` environment variable to another port, and Bubble will listen on
# that port instead.
#
# ### BUBBLE_VM_MEM
# This is the number of MB of memory to allocate for the VirtualBox VM.
# By default, this is set to 2048, thus Vagrantfile allocates 2GB of memory for the VM.
# You can build and run Bubble with less memory, but if you go as low as 1024 (1GB) you
# may have problems building the entire codebase from scratch.
