Please review the frequently asked questions and contributing guidelines before opening issues or submitting pull requests.
Please try the 4.0.0-beta release of this cookbook. Otherwise pin your cookbook back to a '~> 3.0' release. The 4.0.0-beta branch will be promoted to master once it's stable & working with Elasticsearch 6.0 releases.
Please consult attributes/default.rb for a large list of checksums for many different archives and package files of different elasticsearch versions. Both recipes and resources/providers here use those default values.
You may use %s
in your URL and this cookbook will use sprintf/format to insert
the version parameter as a string into your download_url.
Name | Default | Other values |
---|---|---|
default['elasticsearch']['download_urls']['debian'] |
See values. | %s will be replaced with the version attribute above |
default['elasticsearch']['download_urls']['rhel'] |
See values. | %s will be replaced with the version attribute above |
default['elasticsearch']['download_urls']['tarball'] |
See values. | %s will be replaced with the version attribute above |
This cookbook's elasticsearch::default
recipe also supports setting any elasticsearch_
resource using attributes:
default['elasticsearch']['user'] = {}
default['elasticsearch']['install'] = {}
default['elasticsearch']['configure'] = {}
default['elasticsearch']['service'] = {}
default['elasticsearch']['plugin'] = {}
For example, this will pass a username 'foo' to elasticsearch_user
and set a uid to 1234
:
default['elasticsearch']['user']['username'] = 'foo'
default['elasticsearch']['user']['uid'] = '1234'
Resources are the intended way to consume this cookbook, however we have
provided a single recipe that configures Elasticsearch by downloading an archive
containing a distribution of Elasticsearch, and extracting that into /usr/share
.
See the attributes section above to for what defaults you can adjust.
The default recipe creates an elasticsearch user, group, package installation, configuration files, and service with all of the default options.
Please note that there are additional examples within the test fixtures, including a demonstration of how to configure two instances of Elasticsearch on a single server.
The resources provided in this cookbook do not automatically restart services when changes have occurred. They do start services by default when configuring a new service This has been done to protect you from accidental data loss and service outages, as nodes might restart simultaneously or may not restart at all when bad configuration values are supplied.
elasticsearch_service has a special service_actions
parameter you can use to specify what state the underlying service should be in on each chef run (defaults to :enabled
and :started
). It will also pass through all of the standard service
resource
actions to the underlying service resource if you wish to notify it.
You must supply your desired notifications when using each resource if you want Chef to automatically restart services. Again, we don't recommend this unless you know what you're doing.
We are supporting whyrun mode in this cookbook, simply because we're using all builtin resources from core Chef, and these also already support whyrun. If you contribute to this cookbook, please be sure to maintain that or guard dangerous Ruby code with something like if !whyrun_mode? || nested_resource.whyrun_supported?
.
Many of the resources provided in this cookbook need to share configuration
values. For example, the elasticsearch_service
resource needs to know the path
to the configuration file(s) generated by elasticsearch_configure
and the path
to the actual ES binary installed by elasticsearch_install
. And they both need
to know the appropriate system user and group defined by elasticsearch_user
.
Search order: In order to make this easy, all resources in this cookbook use the following search order to locate resources that apply to the same overall Elasticsearch setup:
- Resources that share the same resource name
- Resources that share the same value for
instance_name
- Resources named
default
or resources namedelasticsearch
- This fails if both
default
andelasticsearch
resources exist
- This fails if both
Examples of more complicated resource names are left to the reader, but here we present a typical example that should work in most cases:
elasticsearch_user 'elasticsearch'
elasticsearch_install 'elasticsearch'
elasticsearch_configure 'elasticsearch'
elasticsearch_service 'elasticsearch'
elasticsearch_plugin 'x-pack'
Actions: :create
, :remove
Creates a user and group on the system for use by elasticsearch. Here is an example with many of the default options and default values (all options except a resource name may be omitted).
Examples:
elasticsearch_user 'elasticsearch'
elasticsearch_user 'elasticsearch' do
username 'elasticsearch'
groupname 'elasticsearch'
shell '/bin/bash'
comment 'Elasticsearch User'
action :create
end
Actions: :install
, :remove
Downloads the elasticsearch software, and unpacks it on the system. There are
currently three ways to install -- 'repository'
(the default), which creates an
apt or yum repo and installs from there, 'package'
, which downloads the appropriate
package from elasticsearch.org and uses the package manager to install it, and
'tarball'
which downloads a tarball from elasticsearch.org and unpacks it.
This resource also comes with a :remove
action which will remove the package
or directory elasticsearch was unpacked into.
You may always specify a download_url and/or download_checksum, and you may
include %s
which will be replaced by the version parameter you supply.
Please be sure to consult the above attribute section as that controls how Elasticsearch version, download URL and checksum are determined if you omit them.
NOTE: The :remove
action has not been implemented yet. Pull requests are
very much welcome & encouraged, if you'd like to see this feature.
Examples:
elasticsearch_install 'elasticsearch'
elasticsearch_install 'my_es_installation' do
type 'package' # type of install
version '5.6.5'
action :install # could be :remove as well
end
elasticsearch_install 'my_es_installation' do
type 'tarball' # type of install
dir '/usr/local' # where to install
download_url "https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.7.2.tar.gz"
# sha256
download_checksum "6f81935e270c403681e120ec4395c28b2ddc87e659ff7784608b86beb5223dd2"
action :install # could be :remove as well
end
elasticsearch_install 'my_es_installation' do
type 'tarball' # type of install
version '5.6.5'
action :install # could be :remove as well
end
elasticsearch_install 'my_es_installation' do
type 'package' # type of install
download_url "https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.7.2.deb"
# sha256
download_checksum "791fb9f2131be2cf8c1f86ca35e0b912d7155a53f89c2df67467ca2105e77ec2"
instance_name 'elasticsearch'
action :install # could be :remove as well
end
Actions: :manage
, :remove
Configures an elasticsearch instance; creates directories for configuration,
logs, and data. Writes files log4j2.properties
, elasticsearch.in.sh
and
elasticsearch.yml
.
The main attribute for this resource is configuration
,
which is a hash of any elasticsearch configuration directives. The
other important attribute is default_configuration
-- this contains the
minimal set of required defaults.
Note that these are both not a Chef mash, everything must be in a single level of keys and values. Any settings you pass in configuration will be merged into (and potentially overwrite) any default settings.
See the examples, as well as the attributes in the resource file, for more.
Examples:
With all defaults -
elasticsearch_configure 'elasticsearch'
With mostly defaults -
elasticsearch_configure 'elasticsearch' do
allocated_memory '512m'
configuration ({
'cluster.name' => 'escluster',
'node.name' => 'node01',
'http.port' => 9201
})
end
Very complicated -
elasticsearch_configure 'my_elasticsearch' do
# if you override one of these, you probably want to override all
path_home "/opt/elasticsearch"
path_conf "/etc/opt/elasticsearch"
path_data "/var/opt/elasticsearch"
path_logs "/var/log/elasticsearch"
path_pid "/var/run/elasticsearch"
path_plugins "/opt/elasticsearch/plugins"
path_bin "/opt/elasticsearch/bin"
# override logging parameters
cookbook_log4j2_properties "my_wrapper_cookbook"
template_log4j2_properties "my_log4j2.properties.erb"
logging({:"action" => 'INFO'})
allocated_memory '123m'
jvm_options %w(
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly
-XX:+HeapDumpOnOutOfMemoryError
-XX:+PrintGCDetails
)
configuration ({
'node.name' => 'crazy'
})
action :manage
end
Actions: :configure
, :remove
Writes out a system service configuration of the appropriate type, and enables
it to start on boot. You can override almost all of the relevant settings in
such a way that you may run multiple instances. Most settings will be taken from
a matching elasticsearch_config
resource in the collection.
elasticsearch_service 'elasticsearch'
If you'd like to skip init scripts and systemd scripts, simply pass nil
for
the template file (init_source or systemd_source) and this cookbook will
entirely skip trying to setup those scripts. Combined with changing the default
service actions, this will have the same effect as action :nothing
.
Actions: :install
, :remove
Installs or removes a plugin to a given elasticsearch instance and plugin directory. Please note that there is currently no way to upgrade an existing plugin using commandline tools, so we haven't exposed that feature here either. Furthermore, there isn't a way to determine if a plugin is compatible with ES or even what version it is. So once we install a plugin to a directory, we generally assume that is the desired one and we don't touch it further.
See sous-chefs#264 for more info. NB: You may encounter issues on certain distros with NSS 3.16.1 and OpenJDK 7.x.
Officially supported or commercial plugins require just the plugin name:
elasticsearch_plugin 'analysis-icu' do
action :install
end
elasticsearch_plugin 'shield' do
action :install
end
Plugins from GitHub require a URL of 'username/repository' or 'username/repository/version':
elasticsearch_plugin 'kopf' do
url 'lmenezes/elasticsearch-kopf'
action :install
end
elasticsearch_plugin 'kopf' do
url 'lmenezes/elasticsearch-kopf/1.5.7'
action :install
end
Plugins from Maven Central or Sonatype require 'groupId/artifactId/version':
elasticsearch_plugin 'mapper-attachments' do
url 'org.elasticsearch/elasticsearch-mapper-attachments/2.6.0'
action :install
end
Plugins can be installed from a custom URL or file location as follows:
elasticsearch_plugin 'mapper-attachments' do
url 'http://some.domain.name//my-plugin-1.0.0.zip'
action :install
end
elasticsearch_plugin 'mapper-attachments' do
url 'file:/path/to/my-plugin-1.0.0.zip'
action :install
end
The plugin resource respects the https_proxy
or http_proxy
(non-SSL)
Chef settings unless explicitly
disabled using chef_proxy false
:
elasticsearch_plugin 'kopf' do
url 'lmenezes/elasticsearch-kopf'
chef_proxy false
action :install
end
To run multiple instances per machine, an explicit plugin_dir
location
has to be provided:
elasticsearch_plugin 'x-pack' do
plugin_dir '/usr/share/elasticsearch_foo/plugins'
end
If for some reason, you want to name the resource something else, you may
provide the true plugin name using the plugin_name
parameter:
elasticsearch_plugin 'xyzzy' do
plugin_name 'kopf'
url 'lmenezes/elasticsearch-kopf'
action :install
end
