docker swarm upgrade

Replace your Swarm Manager and Workers with updated versions of docker

  • it's best to replace nodes, don't do apt/yum upgrades.
  • both would work, but VM replacment forces me to think of it as immutable and prevents making pets
  • if you don't want to update join scripts for manager IP's, then do something like Elastic IP's so manager IP's won't change.

Lets assume you have 3 managers and 3 workers on 17.06 and you want to update to 17.12

  • managers: m1, m2, m3

How to copy production database on AWS RDS(postgresql) to local development database.
  1. Change your database RDS instance security group to allow your machine to access it.
    • Add your ip to the security group to acces the instance via Postgres.
  2. Make a copy of the database using pg_dump
    • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
    • you will be asked for postgressql password.
    • a dump file(.sql) will be created
  3. Restore that dump file to your local database.
    • but you might need to drop the database and create it first
    • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>
  • the database is restored

Multiple MySQL Versions with Homebrew

Multiple MySQL Versions for Development

Options included below:

  • Using Docker docker-compose
  • Using Homebrew brew

Using Docker (recommended)

This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

Firefox about:config privacy settings

ABOUT

about:config settings to harden the Firefox browser. Privacy and performance enhancements.
To change these settings type 'about:config' in the url bar. Then search the setting you would like to change and modify the value. Some settings may break certain websites from functioning and rendering normally. Some settings may also make firefox unstable. I am not liable for any damages/loss of data.

Not all these changes are necessary and will be dependent upon your usage and hardware. Do some research on settings if you don't understand what they do. These settings are best combined with your standard privacy extensions (HTTPS Everywhere No longer required: Enable HTTPS-Only Mode, NoScript/Request Policy, uBlock origin, agent spoofing, Privacy Badger etc), and all plugins set to "Ask To Activate".

Brian's List of OSX Tweaks for web developers
#OSX Tweaks:
===========
- Most need reboot to show changes
- Most of these tweaks are just for speed, but some are specific for development
- All of these are to be ran in terminal. The commands to be copy and pasted start after the less-than sign.
- I'm not responsible for any adverse effects to your computer, at all.
##Increase the speed of OS X dialogs boxes:

Set the iTerm tab title to the current directory, not full path.
# 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
# see: ss64.com/bash/syntax-prompt.html
