Puppet Server: Subcommands
/puppetserver/latest/subcommands.html

We've provided several CLI commands to help with debugging and exploring Puppet Server. Most of the commands are the same ones you would use in a Ruby environment --- such as gem, ruby, and irb --- except they run against Puppet Server's JRuby installation and gems instead of your system Ruby.

The following subcommands are provided:

The format for each subcommand is:

puppetserver <subcommand> [<args>]

When running from source, the format is:

lein <subcommand> -c /path/to/puppetserver.conf [--] [<args>]

Note that if you are running from source, you need to separate flag arguments (such as --version or -e) with --, as shown above. Otherwise, those arguments will be applied to Leiningen instead of to Puppet Server. This isn't necessary when running from packages (i.e., puppetserver <subcommand>).

gem

Installs and manages gems that are isolated from system Ruby and are accessible only to Puppet Server. This is a simple wrapper around the standard Ruby gem, so all of the usual arguments and flags should work as expected.

Examples:

$ puppetserver gem install pry --no-ri --no-rdoc
$ lein gem -c /path/to/puppetserver.conf -- install pry --no-ri --no-rdoc

If needed, you also can use the JAVA_ARGS_CLI environment variable to pass along custom arguments to the Java process that the gem command is run within.

Example:

$ JAVA_ARGS_CLI=-Xmx8g puppetserver gem install pry --no-ri --no-rdoc

If you prefer to have the JAVA_ARGS_CLI option persist for multiple command executions, you could set the value in the /etc/sysconfig/puppetserver or /etc/default/puppetserver file, depending upon your OS distribution:

JAVA_ARGS_CLI=-Xmx8g

With the value specified in the sysconfig or defaults file, subsequent commands would use the JAVA_ARGS_CLI variable automatically:

$ puppetserver gem install pry --no-ri --no-rdoc
// Would run 'gem' with a maximum Java heap of 8g

For more information, see Puppet Server and Gems.

ruby

Runs code in Puppet Server's JRuby interpreter. This is a simple wrapper around the standard Ruby ruby, so all of the usual arguments and flags should work as expected.

Useful when experimenting with gems installed via puppetserver gem and the Puppet and Puppet Server Ruby source code.

Examples:

$ puppetserver ruby -e "require 'puppet'; puts Puppet[:certname]"
$ lein ruby -c /path/to/puppetserver.conf -- -e "require 'puppet'; puts Puppet[:certname]"

If needed, you also can use the JAVA_ARGS_CLI environment variable to pass along custom arguments to the Java process that the ruby command is run within.

Example:

$ JAVA_ARGS_CLI=-Xmx8g puppetserver ruby -e "require 'puppet'; puts Puppet[:certname]"

If you prefer to have the JAVA_ARGS_CLI option persist for multiple command executions, you could set the value in the /etc/sysconfig/puppetserver or /etc/default/puppetserver file, depending upon your OS distribution:

JAVA_ARGS_CLI=-Xmx8g

With the value specified in the sysconfig or defaults file, subsequent commands would use the JAVA_ARGS_CLI variable automatically:

$ puppetserver ruby -e "require 'puppet'; puts Puppet[:certname]"
// Would run 'ruby' with a maximum Java heap of 8g

irb

Starts an interactive REPL for the JRuby that Puppet Server uses. This is a simple wrapper around the standard Ruby irb, so all of the usual arguments and flags should work as expected.

Like the ruby subcommand, this is useful for experimenting in an interactive environment with any installed gems (via puppetserver gem) and the Puppet and Puppet Server Ruby source code.

Examples:

$ puppetserver irb
irb(main):001:0> require 'puppet'
=> true
irb(main):002:0> puts Puppet[:certname]
centos6-64.localdomain
=> nil
$ lein irb -c /path/to/puppetserver.conf -- --version
irb 0.9.6(09/06/30)

If needed, you also can use the JAVA_ARGS_CLI environment variable to pass along custom arguments to the Java process that the irb command is run within.

Example:

$ JAVA_ARGS_CLI=-Xmx8g puppetserver irb

If you prefer to have the JAVA_ARGS_CLI option persist for multiple command executions, you could set the value in the /etc/sysconfig/puppetserver or /etc/default/puppetserver file, depending upon your OS distribution:

JAVA_ARGS_CLI=-Xmx8g

With the value specified in the sysconfig or defaults file, subsequent commands would use the JAVA_ARGS_CLI variable automatically:

$ puppetserver irb
// Would run 'irb' with a maximum Java heap of 8g

foreground

Starts the Puppet Server, but doesn't background it; similar to starting the service and then tailing the log.

Accepts an optional --debug argument to raise the logging level to DEBUG.

Examples:

$ puppetserver foreground --debug
