Unable to change elasticsearch version via role and version tag

[karmi]

@jsirex That's bad... I know Chef 11 changed how attributes are handled and evaluated, what Chef version this is?

[jsirex]

I'm using Chef 10.x. At chef wiki.
First, chef applies default attributes. Then overrides default attributes by role, env, etc. If I specify only version in my role-file, for example, download_url stay unchanged, because it is already evaulated by old node.elasticsearch['version'] value. I have to explicitly override atleast version and download_url to make it work.
Also I have to say that I'm very new in Chef and, probably, do something wrong with it.

There's something weird in your case, since attributes set in role have higher precedence then node attributes. I know the same code as in the cookbook works with roles -- I have to add a test role to the cookbook and evaluate that. Make sure you're overriding the attribute in the role file properly -- please post the relevant snippet.

[jsirex]

In role file I put:

override_attributes "elasticsearch" => {
    :version => '0.19.8'
}

On Chefs' side (isn't it? I'm not sure):

1. Chef Evaluate node with default attributes (:version => '0.20.1', :download_url => "http://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.20.1.tar.gz")
2. Chef processes role and override only version attribute (:version => '0.19.8', :download_url => "http://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.20.1.tar.gz")
3. Recipe uses :download_url for downloading and "elasticsearch-#{node.elasticsearch[:version]}" for target folder

About attributes I've read here: http://wiki.opscode.com/display/chef/Attributes

Have a look at what file is Chef trying to download -- it's in the output. Raise the level to debug to see more info.

Actually, the Chef 11 changelog states that the behaviour should work as you expect here, ie. correctly compose the node.elasticsearch.download_url attribute.

@jsirex Any new info here? I'm able to upgrade/downgrade the version just fine, the only problem is that the service isn't restarted.

My steps:

$EDITOR Vagrantfile # Change version to 0.19.0

time CHEF=latest bundle exec vagrant provision precise64
...
DEBUG: Streaming download from http://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.19.0.tar.gz to tempfile /tmp/chef...
INFO: Processing directory[/usr/local/elasticsearch-0.19.0] action create (dynamically defined)
...

time CHEF=latest bundle exec vagrant ssh precise64 -c 'ls -la /usr/local/elasticsearch'
lrwxrwxrwx 1 root root 31 Feb 26 12:57 /usr/local/elasticsearch -> /usr/local/elasticsearch-0.19.0

Please try this out with latest versions of either Chef 10.x or 11.x and post relevant parts of the Chef run output (increase level to DEBUG).

[karmi]

As a side note, the cookbook now installs the pry gem into Chef, so you can put this in your recipes/default.rb file:

require 'pry'
binding.pry

When you run Chef with:

sudo chef-solo -j /etc/vagrant-chef/dna.json -c /etc/vagrant-chef/solo.rb

you'll get an interactive console where you can check and manipulate node attributes etc.

@karmi, thanks.

Looks like I have to upgrade Chef to 11.x.

@jsirex It works on 10.24.0 just fine
