[@revathimanoharan5613]

Nice

[@amandeepsharma2679]

I am wondering if Lets say in case of a high number of nodes, isn't using a push based tool like Ansible is better to install something on different nodes with a single push like command rather than going to each node and pulling the configuration, i know agents can install it by polling , what if we don't want to wait?

[@edurekaIN]

You are correct, but there are always two sides to a coin. Let me give you few advantages of Pull Configuration as well: • When a new server comes up it can get instructions from the master and start doing things. You can’t push instructions to a server that isn’t there, and the server itself is most aware of when it is ready to do stuff. • If a lot of servers come up, they can all do the setup work on their own, they only have to ask the master what to do. I would say it totally depends on your Business Requirement. I think in your case Push Configuration will be a good option, if you don’t have to scale frequently (Add more servers). Hope this helps :)

[@jijujoseph9549]

It was very nice presentation. I am new to these technologies. I have one doubt. You define old Mysql and php versions in master but in slave system, the installations are done with different versions. How?

[@edurekaIN]

If in the config file it is written ensure=>latest then it would install the latest version of that particular application. Hope this helps :)

[@rahulbajaj3806]

[@pyminiongru6539]

while using a pre existing class, can i override an existing resource description with my resource description? Like base class methods can be overridden by child class method definitions in oops

[@edurekaIN]

+pyminion Gru, thanks for checking out our tutorial! Yes, you can override an existing resource description with my resource description. Like base class methods can be overridden by child class method definitions in oops. Hope this helps. Cheers!

[@ramrao3279]

At 21:40 how does the cert created in slave show up in master. Is any step that needs to be done when configuring the slave indicating the master location ? Cheers

[@edurekaIN]

+Ram Rao, thanks for checking out our tutorial! The procedure to follow in order to generate certificate is given below for your reference: Step 1: Edit /etc/puppet/puppet.conf edit below 2 lines [agent] server = test01.edureka.com Step 2: #Also, remove the line templatedir=$confdir/templates, which has been deprecated. · Restart client sudo service puppet restart Step 3: · Generate a client Cert Request puppet agent -t step 4: · On Server, sign the certificate puppet cert sign # replace FQDN with FQDN of client Hope this helps. Cheers!

[@MohammedImran-mg4hc]

If you need to roll back, do we want to remove the existing one and reinstall a older one or just install the older one without removing.

[@edurekaIN]

+Mohammed Imran, thanks for checking out our tutorial! We can rollback to any commits by following the below steps. Step 1: execute the command git log, It will display the commit id of the git commits step 2: git reset --hard Here commit id refers to the commit id to which commit we want to rollback. Hope this helps. Cheers!

[@ananyabanerjee3383]

Hello, Do we need to add a line defining the node in the .pp file? Like : node 'puppetagent' {

[@edurekaIN]

Hey Ananya, thanks for checking out our tutorial! Hostname of the node should be mentioned. Please find below site.pp example file where the hostname(test02.edureka.com) is hostname of slave where puppet agent is running. node 'test02.edureka.com' { include maven } Hope this helps. Cheers!

[@pankajsingh2116]

I'm working as Storage Administrator , on IBM , EMC and Hitachi Storage, netapp storage, will this devops work on san and Nas storage? do I need to learn scripting , coz I don't know scripting....,? wat are the pre requisite skills required for SAN ADMIN for learning devops?

[@edurekaIN]

Hey Pankaj, thanks for your interest in our course. IT experience is the only requirement to take up DevOps training; there are no other prerequisites. So your background definitely helps. Both Developers and Administrators are eligible for taking up DevOps. DevOps is a culture which cultivates the mindset of taking the end to end responsibility of a software. Hence, if you adopt DevOps, you will be doing the same things that you are currently doing, but with more ownership, agility, process and automation. Hence, this domain knowledge is something you will already possess to execute your day-to-day work and is not required to learn scripting afresh to implement DevOps. As far as DevOps tools are concerned, professionals use easy-to-learn yaml language which can be easily picked up during a training. In a nutshell there is no pre-requisite to take up DevOps Training both for developers and administrators. Also, at the same time your prior experience of administration will be of help as you will need to deal with lot of servers & configurations when working on automation in DevOps. You can get a head-start in DevOps with our course; check it out here: www.edureka.co/devops. Please feel free to get in touch with us if you have any questions or need any assistance. Hope this helps. Cheers!

[@krishnajunk]

Puppet sounds like deployment tool? As it installed some software. Can we treat Puuppet as both configurtion and deployment tool? What is the difference?

[@edurekaIN]

Hey jnnjnj, yes we can treat Puppet as both configuration and deployment tool. Hope this help!

[@Akbar_khaan]

difference between github and puppet in brief???

[@edurekaIN]

+Akbar Khan, thanks for checking out our tutorial! Here's the difference: Github is the version control tool which is used to keep a track of the code and it is nothing but a storage location or centralized repository where the developers commit their codes, Puppet is a configuration management tool. For example, if we want to install Apache in 100 servers, instead of going to each server and installing it, we can use puppet to install and configure Apache in one go. Hope this helps. Cheers!
