Setup minimal Certificate Authority (CA)

1. Setup directory

Setup a directory to be used as the root of the certificate authority, e.g /home/user/documents/identity/ca.

First, create the root key/certificate pair root.{key,crt} that will be used to sign client requests. For example:

    openssl genrsa -out root.key 4096

Setup Keycloak (5.0)

This is a checklist of steps to be taken to setup the identity server (in standalone mode). We assume that keycloak is installed under /usr/local/keycloak (so all paths will be relative to this).

1. Add module for PostgreSQL database

Under modules/org/postgresql/main we must place:

• module.xml: descriptor for the module
• postgresql-*.jar: the actual JAR for the PostgreSQL JDBC driver

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

• Plain ASCII
• ANSI escape codes: 16 color codes with bold/italic and background
• 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
• 24-bit true color: "888" colors (aka 16 milion)

Auto-enable Local HTTP Caching in Test Kitchen

Note: total experiment and hack, looks nasty, could be awesome:

Setup

• Drop the kitchen.local.yml into $HOME/.kitchen/config.yml
• Install polipo (with Mac: brew install polipo, with Ubuntu: apt-get install polipo)
• Drop polipo-start and polipo-console somewhere useful (perhaps $HOME/bin?)

How To setup polipo on OSX

• Install polipo with brew install polipo

• Edit your ~/.bashrc or ~/.zshrc and include

$PLIST_FILE=~/opt/homebrew.mxcl.polipo.plist
alias launch-polipo='launchctl load $PLIST_FILE'
alias stop-polipo='launchctl load $PLIST_FILE'

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

# Synchronize history between bash sessions
#
# Make history from other terminals available to the current one. However,
# don't mix all histories together - make sure that *all* commands from the
# current session are on top of its history, so that pressing up arrow will
# give you most recent command from this session, not from any session.
#
# Since history is saved on each prompt, this additionally protects it from
# terminal crashes.
