Specify chef bootstrap Ubuntu gems version

[Thomas]

Hi,
How can one specify which Ubuntu version of the bootstrap Ubuntu gems file to use? I'm trying to setup a node
using chef for an Ubuntu 12.04 machine but the gems file use is always ubuntu10.04-gems.erb (there exists one ubuntu12.04-gems.erb)
which fails the install. Can I specify chef to use the 12.04 version via jclouds-chef?

Hi Thomas,

There are several ways of using Chef with jclouds:

1. You can manually install all Chef gems and manually configure the chef-client (not the recommended one :)).

2. If you have a Chef Server (or a Hosted or Private Chef) you can use the jclouds-chef project.

3. If you don't have a Chef Server, you can use Chef Solo to bootstrap and configure your node. This is only available in jclouds 1.6.0-SNAPSHOT.

If you are using approach (1), I'd recommend to use the InstallChefGems statement [1], since it will take care of installing the required gems. However, this is only available since jclouds-1.6.0-SNAPSHOT, so I don't know if you would be able to use it.

If you are using approach (2), you should use the jclouds-chef project to bootstrap your node. It will take care of installing all required Chef gems, registering the node in the Chef server and execute its run list. You can find examples here: [2].

If you prefer to use Chef Solo, you can take a look at this blog post [3] that shows a couple of examples of how to use that statement (this is only available in jclouds-1.6.0-SNAPSHOT).

You can also take a look at the chef-basics example [4] to see jclouds-chef and Chef Solo in action.

If you use the approaches above you should not have issues regarding the version of Chef gems.

Let us know if this works for you!

Hi Ignasi,

Thank you for the answer!

I went for approach (2), It still seems to try and use Ubuntu 10.04 install gems. What I really would like to do is something similar to Knife Bootstrap [1] --distro flag and specify Ubuntu 12.04.

If you are using jclouds-chef 1.5.x, then ruby and chef gems are installed using:

https://github.com/jclouds/jclouds-chef/blob/1.5.x/core/src/main/resources/org/jclouds/chef/statements/install-chef-gems.sh

If you are using version 1.6.0-SNAPSHOT, then, they are installed using:

https://github.com/jclouds/jclouds/blob/master/scriptbuilder/src/main/java/org/jclouds/scriptbuilder/statements/chef/InstallChefGems.java

https://github.com/jclouds/jclouds/blob/master/scriptbuilder/src/main/java/org/jclouds/scriptbuilder/statements/ruby/InstallRuby.java

https://github.com/jclouds/jclouds/blob/master/scriptbuilder/src/main/resources/functions/installRuby.sh

All those scripts should do something very close to what knife bootstrap does:

https://github.com/opscode/chef/tree/master/lib/chef/knife/bootstrap

Could you confirm which jclouds version you are using?

[Thomas]

I see, I'm using 1.5.3.

[Ignasi]

Could you please share the error you are getting, to see how we can improve the script to take care of installing the gems properly?

The libruby-extras and libruby1.8-extras packages have been removed from Ubuntu 12.04, but they are not required to be able to run Chef, so we have removed them in 1.6.0-SNAPSHOT.

If the bootstrap is failing because it can not find those packages, could you try with 1.6.0-SNAPSHOT, to see if it fixes your issue?

[Thomas]

Yeah it fail because of libruby1.8-extras and libruby-extras.

Now I have migrated to 1.6.0-SNAPSHOT and tested my program, It was a success! Thanks for the suggestions!
