Amazon VPC | Creating a VPC from Scratch
 
28:04
VPC stands for Virtual Private Cloud , is one of the fundamental and widely used AWS service which provides a virtual network dedicated for the AWS environments. It is logically isolated from the other virtual networks in the Cloud and exists within a single region. Benefits of using VPC - Define custom network. - Assign static private IPv4 addresses to the instances. - Define network interfaces and attach one of more network interface to the instances. - Define the routing between different subnets. - Define the internet access for the subnets. - Define your network security by allowing/denying the traffic . LAB In this lab we are going to create a new VPC . VPC will be having 02 subnets, one subnet will have internet connectivity and second will be without internet connectivity. Both subnets can talk with each other through the default routing table. , but we will allow only specific ports using security groups ( firewall). VPC Name / CIDR : awslab-vpc 172.16.0.0/16 Subnet Name / CIDR : awslab-subnet-public 172.16.1.0/24 Internet Gateway Connectivity : Yes Routing Table : awslab-rt-internet Subnet Name : awslab-subnet-private 172.16.2.0/24 Internet Gateway Connectivity : No Watch video for details :

Jenkins CICD  |  Jenkins Configuration Backup and Restore
 
13:56
Backing up data is crucial to any business and Jenkins is not a exception. If you have right backup’s it gives you peace of mind in case of any recovery needed to tackle with any unexpected situations like , datacenter outage , Jenkins system failures or accidental deletion of data. There are multiple method to backup the Jenkins configuration such as using ThinBackup or Backup plugin using the git repo manually backing up the Jenkins configuration or schedule a shell script using the cron. The easiest approach which I found is to use the Jenkins plugin for the backup. In this quick demo we are going install ThinBackup plug-in and configure the backups and then a test restore.

Configuring and Managing the NFS on the Enterprise servers is one of the tasks for systems administrators. NFS is most common file system sharing solution on Linux/Unix systems. Assume a scenario; you have to configure NFS on multiple systems quickly for some deployments? Ansible can help us to automate this. I have written a small playbook, which you can customize further to install, configure and manage the NFS on Linux/Unix Systems. Below modules as part of tasks 1. Yum 2. Template 3. Service 4. File Along with modules, I have used variables to make this demo playbook more efficient. Please Note – this playbook is very basic playbook. Once you are good with basics you can integrate these tasks in Ansible roles for easy management. Note – please use this playbook at your own responsibility/risk.

Docker Swarm |  Create SWARM Cluster from Scratch
 
28:51
Swarm is native clustering for the Docker. When the Docker Engine runs in swarm mode, manager nodes implement the Raft Consensus Algorithm to manage the global cluster state.The reason why Docker swarm mode is using a consensus algorithm is to make sure that all the manager nodes that are in charge of managing and scheduling tasks in the cluster, are storing the same consistent state. LAB Setup In this LAB we are going to create a SWARM cluster with single manager and 02 worker nodes. Operating System : CentOS 7.3 x86_64 Platform : Vagrant Machines Manager Node : manager | 192.168.1.100/24 Worker Node 1 : node-1 | 192.168.1.101/24 Worker Node 2 : node-2 | 192.168.1.102/24 Watch the video for more details :
