更改AWS OpsWorks中的主机名(厨师)

我想通了。您应该覆盖AWS提供的Chef中的默认模板。

Extending AWS OpsWorks Configuration Files Using Custom Templates

所以在我的食谱中,我制作了一个文件,名为:

opsworks_stack_state_sync/templates/default/hosts.erb

添加文件如下所示:

# This file was generated by OpsWorks
# any manual changes will be removed on the next update.

# Set the hostname with proper format, the rest are aliases.
127.0.0.1 localhost localhost.example.com
127.0.1.1 <%= node[:opsworks][:instance][:hostname] %>.example.com <%= node[:opsworks][:instance][:hostname] %>

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

# OpsWorks Layer State
<% seen = [] -%>
<% node[:opsworks][:layers].each do |layer_name, layer_config| -%>
<% layer_config[:instances].each do |instance_name, instance_config| -%>
<% if !seen.include?(instance_name) && instance_config[:private_ip] -%>
<%= Resolv.getaddress(instance_config[:private_ip]) %> <%= instance_name %>
<% if instance_config[:ip] %>
<%= Resolv.getaddress(instance_config[:ip]) %> <%= instance_name %>-ext
<% end %>
<% seen << instance_name %>
<% end -%>
<% end -%>
<% end -%>

这会将主机名设置为 应用程序pie.example.com .
