# define: nginx::resource::upstream
|
|
#
|
|
# This definition creates a new upstream proxy entry for NGINX
|
|
#
|
|
# Parameters:
|
|
# [*members*] - Array of member URIs for NGINX to connect to. Must follow valid NGINX syntax.
|
|
# If omitted, individual members should be defined with nginx::resource::upstream::member
|
|
# [*ensure*] - Enables or disables the specified location (present|absent)
|
|
# [*upstream_cfg_prepend*] - It expects a hash with custom directives to put before anything else inside upstream
|
|
# [*upstream_fail_timeout*] - Set the fail_timeout for the upstream. Default is 10 seconds - As that is what Nginx does normally.
|
|
# [*upstream_max_fails*] - Set the max_fails for the upstream. Default is to use nginx default value which is 1.
|
|
#
|
|
# Actions:
|
|
#
|
|
# Requires:
|
|
#
|
|
# Sample Usage:
|
|
# nginx::resource::upstream { 'proxypass':
|
|
# ensure => present,
|
|
# members => [
|
|
# 'localhost:3000',
|
|
# 'localhost:3001',
|
|
# 'localhost:3002',
|
|
# ],
|
|
# }
|
|
#
|
|
# Custom config example to use ip_hash, and 20 keepalive connections
|
|
# create a hash with any extra custom config you want.
|
|
# $my_config = {
|
|
# 'ip_hash' => '',
|
|
# 'keepalive' => '20',
