haproxy-tools
Tools for managing HAProxy with Ruby.
Installation
gem install haproxy-tools
Gemfile
gem 'haproxy-tools', '~> 0.4.0'
Basic Configuration File Parsing
require 'haproxy-tools'
config = HAProxy::Config.parse_file('spec/fixtures/multi-pool.haproxy.cfg')
config.backend('logs').servers.each do |name, server|
puts "Server: #{server.name} #{server.host}"
end
Managing the Server List
require 'haproxy-tools'
config = HAProxy::Config.parse_file('spec/fixtures/multi-pool.haproxy.cfg') # Parse the config file
logs = config.backend('logs') # Get the backend
logs.servers['logs4'] = HAProxy::Server.new('logs4', '127.0.0.1') # Add a new server
logs.servers.delete_if {|name, server| name == 'logs4'} # Remove a server
Rendering the Configuration File
require 'haproxy-tools'
config = HAProxy::Config.parse_file('spec/fixtures/multi-pool.haproxy.cfg') # Parse the config file
backend = config.backend('www_main') # Get the www_main backend
backend.servers.delete('prd_www_1') # Delete one of the servers
new_config_text = config.render # Render the new config
File.open('new-haproxy.cfg', 'w') { |f| f.puts new_config_text } # Write the config to a file
new_config = HAProxy::Config.parse_file('new-haproxy.cfg') # Parse the new config file
new_config.backend('www_main').servers['prd_www_1'] # Confirm that the server is removed
# => nil
