To make it and easier for everyone, and save us some time please prepare a couple of simple things beforehand. Coming unprepared can cause delays and you might miss the whole workshop because the internet is not fast enough for everyone to download the requirements.

Working with ansible-vault

---

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

# Add a domain user to a remote server local group, if your current user has admin over the remote machine
powershell -c ([ADSI]'WinNT://SERVER/Administrators,group').add('WinNT://DOMAIN/USER,user')

# Get all local groups on a remote server
powershell -c "([ADSI]'WinNT://SERVER,computer').psbase.children | where { $_.psbase.schemaClassName -eq 'group' } | foreach { ($_.name)[0]}"

# Find members of the local Administrators group on a remote server
powershell -c "$([ADSI]'WinNT://SERVER/Administrators,group').psbase.Invoke('Members') | foreach { $_.GetType().InvokeMember('ADspath', 'GetProperty', $null, $_, $null).Replace('WinNT://', '') }"

# Enable the local Administrator account on a remote server

# Problem:
#
# If you use git submodules linking two private github repos, you'll need to create a separate deploy key for each.
# Multiple keys are not supported by Ansible, nor does ansible (when running git module) resort to your `.ssh/config` file.
# This means your ansible playbook will hang in this case.
#
# You can however use the ansible git module to checkout your repo in multiple steps, like this:
#
- hosts: webserver
  vars:
