Creating Custom Vagrant Boxes for Integration Testing

Posted on by rchapin

For some things, a docker container will not work. For example, I am working on a Python project to automate the deployment and configuration of VMs and bare-metal boxes. It involves installing packages and configuring the OS and to properly test it requires a full fledged VM and not just a container.

Use packer to define the box you want to build

Install packer. The description straight from apt show packer is “HashiCorp Packer – A tool for creating identical → Continue reading “Creating Custom Vagrant Boxes for Integration Testing”

Using Environment Variables in a Vagrant File

Posted on by rchapin

An easy way to parameterize a Vagrant file is to use environment variables. You simply need to export a variable and then refer to it in the Vagrant file with the following syntax.

Export the variable:

export SSH_PORT=22222

Sample Vagrant file that reads the exported variable

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  config.vm.box = "debian/bullseye64"
  config.vm.box_version = "11.20221219.1"

  config.vm.network "forwarded_port", guest: 22, host: ENV['SSH_PORT']
end

Declaring, Exporting, and Reading Dynamic Variables in Bash

Posted on by rchapin

If you want to dynamically define and export variable names in Bash here is the TLDR;

# Define the name of the variable
key="my-dynamic-var-name"

# Declare it and export it
declare -gx "$key"="some-value"

To then access that value via a dynamically generated variable name

# Create a variable that contains the variable name
var_to_access="my-dynamic-var-name"

# Read the value
my_var_value=${!var_to_access}

Read the man page for declare for more details and read this article for a really good explanation and further examples.→ Continue reading “Declaring, Exporting, and Reading Dynamic Variables in Bash”
