Installing a Particular Library Version

问题

Using vagrant-berkshelf with the Maven and Tomcat cookbooks, I can specify a major version to install.

Example: Maven - 2 or 3 Tomcat - 5 or 6

If I want to specify an exact version of a library (Maven 3.2.1), should I just use the Ark Cookbook to install the desired version?

Having limited DevOps experience, I'm used to making use of yum or apt-get to manage my libraries without specifying a particular version.

回答1:

The Maven cookbook already uses ark. So you could just override the following node attributes:

node['maven']['version'] = 3
node['maven']['3']['version'] = '3.2.1'
node['maven']['3']['url'] = ???
node['maven']['3']['checksum'] = ??? 

The tomcat cookbook on the other hand does a package install, so you'd need to use ark or build a Deb/RPM package.

The only downside to using ark for tomcat is that you won't have service scripts to manage tomcat's stop/start/status. Some extra work would be needed.

Update

The following is a vagrant project that installs Maven 3.2.1
