Increasing tomcat memory using puppets

Question

I am trying to install / install tomcat7 using a puppet.

I did not find a module that allows me to configure the maximum heap memory.

So, I'm trying to enter the line "CATALINA_OPTS = -Xmx2048m" in the file catalina.sh.

I'm not quite sure what the best way to do this. I looked at the file_line resource, but I don’t know how to insert it in the middle of the catalina.sh file.

Any suggestions are welcome.

Update: Some people suggested templates, but I do not need to parameterize anything. I want to be able to take any catalina.sh file that installs tomcat and enter a line into it. If I used templates or replaced the modified copy file, then the next tomcat that I install may have a different catalina.sh file, and this will overwrite the new file format.

Maybe I need a way to insert a row AFTER another row. I believe that I can insert "CATALINA_OPTS =" immediately after the line #! / Bin / bash. Is it possible?

Answer 1

Use the file_line parameter matches, so the existing CATALINA_OPTS line in the source file will be replaced with a new line.

  file_line { "Tomcat Memory":
    line => "CATALINA_OPTS=-Xmx2048m",
    path=> "/route/to/catalina.sh",
    notify =>Service['tomcat'],
    match => "CATALINA_OPTS=.*",
  }

. . :

class your_module_name ($memory='2048m') {
    file { '/where/is/catalina.sh':
        owner   => 'root',
        group   => 'root',
        mode    => '0755',
        content => template('your_module_name/catalina.sh.erb');
    }
}

catalina.sh modules/your_module_name/templates/catalina.sh.erb. :

CATALINA_OPTS=-Xmx<%=memory%>
