Puppet - Fact Conditionals

 Exercise  - Fact Conditionals

 Go to agent terminal window and run the following command

facter

 This will display the facts gathered from the agent node by the factor application running with Puppet

 Go to the master terminal and create a file factconditional.pp and add the following

nano factconditionals.pp

if $::operatingsystem == ‘Ubuntu’ {

notify {‘Installing on Ubuntu’:}

}

 Go to the master terminal and run this command.

puppet apply factconditionals.pp

 Go to the master terminal and update ap factconditionals.pp to add the following

nano factconditionals.pp

if $::operatingsystem == ‘Ubuntu’ {

notify {‘Installing on Ubuntu in if statement’:}

}

case $::operatingsystem {

‘Ubuntu’: {

notify {‘Installing on Ubuntu in case’:}

}

‘RedHat’: {

notify {‘Installing on Red Hat’:}

}

}

 Go to the master terminal and run this command.

puppet apply factconditionals.pp

 You will see that Puppet has applied the case statement install first and then the if statement. When there are no relational dependencies between different statements Puppet decides which condition, it wants to apply first based on the most efficient installation and no necessarily on the order in which its written in your manifest.

 If there are relational dependencies between statements then it applies in the order they are mentioned in the manifest.

nano conditionals.pp

case $my_variable {

‘One’: {

notify {‘The value of my variable is One’:}

}

default: {

{“The value of my variable is $my_variable in the case statement”:}

}

}

Different Types of Reports in Scrum - Agile

  Introduction to Agile Reporting I’m not going to elaborate on the Agile Framework itself here.  1. Sprint Burndown At a Sprint-level, the burndown presents the  easiest way to track and report status  (the proverbial  Red / Amber / Green ), i.e., whether your Sprint is on or off-track, and what are the chances of meeting the Sprint goals. The burndown chart – when used right – can provide  near-real time updates  on Sprint progress. “If your team do it right, then they would take in just the right amount of work into a sprint.” At the beginning of a Sprint, the Scrum team perform Sprint Planning and agree to take on development work worth a certain number of Story points. This forms the basis for the Sprint Burndown chart. The total story points agreed at the beginning of the sprint make up the y-axis, and the individual dates in the Sprint make up x-axis. If your team do it right, then they would take in just the right amount of work into ...
