Provide define to install plugins about puppet-elasticsearch

[salekseev]

Any plans for implementation in the near term? Thanks.

Hi,

Im currently doing some investigation on the different options for plugin installs and see how i can nicely put that in a define.
I hope to have this feature done within a week.

If you have a plan of implementation, maybe I can help. I was thinking of duplicating/refactoring the code from http://ti57.blogspot.com/2013/03/installing-elasticsearch-using-puppet.html that relates to installing plugins.

You are more then welcome to submit a PR :-)

My idea is to have a define that can handle the different type's of sources:

• Github
• Download.elasticsearch.org
• Local file

Not sure yet about the checking if a plugin is already installed or not.

First off -- great work on this @electrical !

For those watching this issue, I simply add this to the node definition to install a plugin:

exec { 'install-bigdesk-plugin':
  command => '/usr/share/elasticsearch/bin/plugin -install lukas-vlcek/bigdesk/2.0.0',
  creates => '/usr/share/elasticsearch/plugins/bigdesk',
}~>Service['elasticsearch']

@justindowning Thanks for the kind words and the tip :-)
Will take that in account.

Installed plugins could be queried by HTTP in JSON format i.e. http://$::ipaddress:9200/_nodes/$::node.name/plugin will return something like:

{"ok":true,"cluster_name":"athena.syseng.lab.es.logstash","nodes":{"Dk2vnG4PQu26fhQ1RQF9Og":{"name":"lab027","transport_address":"inet[lab027.athenalab.athenahealth.com/10.7.212.37:9300]","hostname":"lab027.athenalab.athenahealth.com","version":"0.90.0","http_address":"inet[/10.7.212.37:9200]","plugins":[{"name":"river-rabbitmq","description":"River RabbitMQ Plugin","jvm":true,"site":false},{"name":"bigdesk","description":"No description found for bigdesk.","url":"/_plugin/bigdesk/","jvm":false,"site":true},{"name":"head","description":"No description found for head.","url":"/_plugin/head/","jvm":false,"site":true},{"name":"paramedic","description":"No description found for paramedic.","url":"/_plugin/paramedic/","jvm":false,"site":true}]}}}

Ah cool :-) that could give a good option to check if a plugin is installed without having to know where its installed.

[electrical]

Almost finished with the main part.
Still looking at how to verify its installed. for some reason the solution from @salekseev doesn't work on my ES install. perhaps mine is just to old ( 0.20.2 )

[salekseev]

The HTTP API information is from http://www.elasticsearch.org/guide/reference/api/admin-cluster-nodes-info/, I'll try to reach out to them to see what's the oldest version that supports it. Do you get anything back or just an error?

[electrical]

@salekseev Finally been able to do some work on it.
It seems that the plugin info has been added into the 0.90.0 release?
Tried 0.20.2 till 0.20.6 and those gave nothing.

Now i can continue further on it :-)

[electrical]

Basic plugin install is implemented.
Might improve it in the future if required.
Please test it out :-)
