Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

Build Status

Alert Logic Agent Cookbook

This cookbook is used to install and configure the Alert Logic agent.

Requirements

The following platforms are tested directly under test kitchen.

  • ubuntu-12.04
  • ubuntu-14.04
  • centos-6.4
  • centos-7.0
  • debian-7.8
  • fedora-19
  • windows-2012r2

Cookbook Dependencies

  • rsyslog
  • line
  • selinux_policy

Attributes

  • ['al_agents']['agent']['registration_key'] - your required registration key. String defaults to your_registration_key_here
  • ['al_agents']['agent']['for_autoscaling'] - The for_autoscaling attribute determines if your installation will be configured as a host or role server. By default for_autoscaling is set to false or in other words as a host install. If autoscaling is set to true then the install is configured as a role server. Boolean defaults to false
  • ['al_agents']['agent']['for_imaging'] - The for_imaging attribute determines if the install process will continue or stop prior to provisioning. If the for_imaging attribute is set to true then the install process perform an install only and stop before provisioning. This allows for instance snapshots to be saved and started for later use. With this attribute set to false then the provisioning process is performed during setup. Boolean defaults to false
  • ['al_agents']['agent']['egress_url'] - By default all traffic is sent to https://vaporator.alertlogic.com:443. This attribute is useful if you have a machine that is responsible for outbound traffic (NAT box). If you specify your own URL ensure that it is a properly formatted URI. String defaults to https://vaporator.alertlogic.com:443
  • ['al_agents']['agent']['proxy_url'] - By default al-agent does not require the use of a proxy. This attribute is useful if you want to avoid a single point of egress. When a proxy is used, both ['al_agents']['agent']['egress_url'] and ['al_agents']['agent']['proxy_url'] values are required. If you specify a proxy URL ensure that it is a properly formatted URI. String defaults to nil

Usage

al_agents::default

The default recipe will attempt to perform an install best suited for your environment. It will install the package for your system. The default attributes will install the agent in host mode (not for image capture).

On linux, the default recipe includes an attempt to detect your logging system and adds a configuration directive for that logging system. For more information see the al_agents::rsyslog and al_agents::syslog_ng recipes. This recipe also includes an attempt to detect if selinux is installed on the machine.

On both windows and linux the proper package is installed and the agent is started when the cookbook's defaults are used.

al_agents::rsyslog

On linux, if you are using rsyslog and desire to skip an attempt at detection, you may run the al_agent::rsyslog recipe independently. Logging changes are added under the installation's subdirectory in a file named alertlogic.conf

al_agents::syslog_ng

On linux, if you are using syslog-ng and desire to skip an attempt at detection, you may run the al_agents::syslog_ng recipe independently. Logging changes are added under the installation's subdirectory in a file named alertlogic.conf

al_agents::selinux

On linux, if you are using selinux and desire to skip an attempt at detection, you may run the al_agents::selinux recipe independently. This recipe will add a selinux policy to allow for logging to port 1514. This recipe does not enable nor disable selinux policy enforcement.

al_agents::install

On linux, should you desire to install the package, configure and provision the machine you may run this recipe independently.

al_agents::start

On linux, this recipe as stated starts the service.

Examples

install example
{
  "name":"my_server",
  "run_list": [
    "recipe[al_agents]"
  ]
}
à la carte recipe example (linux only)
{
  "name":"my_server",
  "run_list": [
    "recipe[al_agents::rsyslog, al_agents::install]"
  ]
}

Configurations

The attributes for_autoscaling and for_imaging determine your installation type. They are boolean values and by default both of those values are false. As boolean values, you can create a matrix of four possible configuration outcomes. It is worth mentioning those configurations.

  1. host (default) when for_autoscaling = false and for_imaging = false
  2. host for imaging when for_autoscaling = false and for_imaging = true
  3. role when for_autoscaling = true and for_imaging = false
  4. role for imaging when for_autoscaling = true and for_imaging = true

Performing an agent install using the cookbook's default attributes, will setup the agent as a host type and provision the instance immediately. see configuration #1 above. If you have properly set your registration key, your host should appear within Alert Logic's Console within 15 minutes.

Testing

In the root of the project: * to execute rubocop: rubocop . * to execute foodcritic: foodcritic . * to execute chefspec: rspec spec * to execute test kitchen: kitchen test

Troubleshooting

If the cookbook fails at the provisioning step, one cause is that the agent cannot connect to the egress_url. Ensure that the proper permissions are configured on the security groups and ACLs to allow for outbound access. Also check your egress_url attribute and ensure that it is a properly formatted URI.

CloudInit

Alert Logic provides an example for using CloudInit and chef-solo to install and configure agents. CloudInit is the way to install something onto cloud instances (i.e. amazon ec2). In case of amazon ec2 just pass this .yml file as user-data, do not forget to change registration_key. If you would like to route traffic through a SOCKS or HTTP proxy, set the proxy_url value to point to your specific proxy. This will install chef-client to your instance, download this cookbook and run chef-solo.

Note that in case of amazon ec2 user-data will be accessible to any user from within this instance.
