For the scenario, imagine posts has a foreign key user_id referencing users.id
public function up()
{
Schema::create('posts', function(Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->text('body');
# put this in your .bash_profile | |
if [ $ITERM_SESSION_ID ]; then | |
export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND"; | |
fi | |
# Piece-by-Piece Explanation: | |
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment | |
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too | |
# the $PROMPT_COMMAND environment variable is executed every time a command is run | |

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.

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important
or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”
