Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

• install packages for vim, git
• create user accounts, as specified in included JSON config files
• install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

Vagrant with Ansible Provisioner on Windows

Long story short, ansible does not work on a Windows control machine, so you basically have to:

• either run ansible --connection=local ... in the target vm
• set up a separate control vm where ansible is installed via shell provisioner

Below are Vagrantfile examples for both approaches

Within the Target VM

Requirements

• no upfront installation/agents on remote/slave machines - ssh should be enough
• application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
• configuration templating
• environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
• deployment process run from Jenkins

//specify what state slices you would like to keep synced with local storage
export function main() {
  return bootstrap(TodoApp, [
      provideStore(APP_REDUCERS),
      localStorageMiddleware('todos', 'visibilityFilter')
  ])
  .catch(err => console.error(err));
}
