This cookbook is released on Chef Supermarket. You can install the cookbook using Berkshelf.

$ echo 'cookbook "td-agent"' >> Berksfile
$ berks install

Installing with knife-github-cookbooks

The knife-github-cookbooks gem is a plugin for knife that supports installing cookbooks directly from a GitHub repository. To install with this plugin, please follow these steps:

$ gem install knife-github-cookbooks
$ cd chef-repo
$ knife cookbook github install treasure-data/chef-td-agent

NOTICE

This cookbook may be used on Amazon Linux but we cannot guarantee if td-agent will work properly because AWS doesn't guarantee binary compatibility with RHEL (they aim to be "as compatible as possible"). If users encounter any compatibility issues with td-agent on Amazon Linux, they should contact AWS.

REQUIREMENTS

This cookbook has these external dependencies.

• apt cookbook
• yum cookbook

ATTRIBUTES

api_key

API Key, and the Secret Key are required.

• node[:td_agent][:api_key] (required)

plugins

A list of fluentd plugins to install. The fluent-plugin- prefix is automatically added. Additional variables can be passed.

• node[:td_agent][:plugins]

Example

This installs the latest version of fluent-plugin-flowcounter and version 0.0.9 of fluent-plugin-rewrite.

node[:td_agent][:plugins] = [
  "flowcounter",
  { "rewrite" => { "version" => "0.0.9" } }
]

version

You can install the latest td-agent 2 using the version attribute and major version.

node[:td_agent][:version] = '2'

You can also specify the full version.

node[:td_agent][:version] = '2.0.4'

pinning_version and version

If pinning_version is true, then version's td-agent will be installed. The default version is the latest version.

• node[:td_agent][:pinning_version]
• node[:td_agent][:version]

In this case, you should set the full version in node[:td_agent][:version].

Limitation

pinning_version and version attributes are now available for rpm packages. They are unsupported for deb packages because the td-agent repository currently uses reprepro for building deb repositories, which can not handle multiple versions of the same package.

uid

UID of td-agent user. Automatically assigned by default.

gid

GID of td-agent group. Automatically assigned by default.
