There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file. Create a file called .gitignore in your home directory and add anything you want to ignore. You then need to tell git where your global gitignore file is.

Mac

git config --global core.excludesfile ~/.gitignore

Windows

git config --global core.excludesfile %USERPROFILE%\.gitignore

PostgreSQL Streaming Replication With Docker

The *.txt files here hold user and database parameters. Specifically, replication.txt contains the user/role and password to use for replication. Whereas database.txt contains an initial database, user/role and password to create on the master.

Run the master:

$ fig run -d master

Wait for it to start up completely. Start the slave:

# Windows AMIs don't have WinRM enabled by default -- this script will enable WinRM
# AND install 7-zip, curl and .NET 4 if its missing.
# Then use the EC2 tools to create a new AMI from the result, and you have a system 
# that will execute user-data as a PowerShell script after the instance fires up!
# This has been tested on Windows 2008 SP2 64bits AMIs provided by Amazon
# 
# Inject this as user-data of a Windows 2008 AMI, like this (edit the adminPassword to your needs):
#
# <powershell>
# Set-ExecutionPolicy Unrestricted
