 Namaste, In this exciting Docker storage volume story, this experiment is going to use two Vagrant VirtualBox. You can also use any two Cloud instances (may be GCP, AWS, Azure etc.,). Where DockerHost is going to run the docker containers and DockerClient box is going to run the SSH daemon.  Docker Volume with External Storage using SSHFS Docker allows us to use external storage with constraints. These constraints will be imposed on cloud platforms as well. The external or Remote volume sharing is possible using NFS.  How to install SSHFS volume? Step-by-step procedure for using external storage as given below : Install docker plugin for SSHFS with all permission is recommended: docker plugin install \ --grant-all-permissions vieux/sshfs Create a Docker Volume docker volume create -d vieux/sshfs \ -o sshcmd=vagrant@192.168.33.251:/tmp \ -o password=vagrant -o allow_other sshvolume3 Mount the shared folder on the remote host: mkdir /opt/remote-volume # In rea...

Hello, dear DevOps Enquist, in this post I would like to discuss with you how to install Docker Enterprise Edition on CentOS 7 and plus Universal Control Plane (UCP) running to control the master and workers on three nodes(Virtualboxes). Amazed with the great features that incorporated into the UCP. You could do lot of things from your browser itself. In the last post I've explored about the swarm cluster that time I'd executed everything on CLI, but this time UCP Web UI. Why we need a Docker Universal Control Plane(UCP)? To make more production-ready setup we would do this experiment with three CentOS7 nodes. The following picture tells us how powerful UCP in Docker Enterprise Edition is. You can manage services, multiple deployments using stacks, summary and manage docker containers and their images. you can also add/remove nodes and get their status, category. Docker network full control on it. Storage volumes also you can manage from the UCP admin console. Ease of us...

Hello DevOps enthusiast, I'm here with another interesting article on one more DevOps automation tool that is Jenkins CI, where I've explored all possible new learnings which will be used by DevOps. Jenkins installation on CentOS or RHEL or Fedora Simple instructions I've made for reference, which I've used. What are the Pre-requisites for the Jenkins installation Good speed of Internet Either of the platforms will be working: Vagrant installed VirtualBox installed to pull CentOS7 box AWS RHEL instance up and running  Bring up the CentOS/7 box (optional) Note: Ignore this section if you have a Cloud instance ready. Step 1: Create your own CentOS7 vagrant box with the following DSL Vagrantfile: Vagrant.configure(2) do |config| config.vm.box = "centos/7" config.vm.boot_timeout=600 config.vm.host_name = "mydev.devopshunter.com" config.vm.network "private_network", ip: "192.168.33.100" config.vm.syn...

Thanks to Rajkumar who had developed the Vagrantfile and published in the github on Kubernetes cluster configuration in a Virtualbox with vagrant. For those who don't know about Vagrant it is a tool that will be used for virtualization into a different level and more powerful way of using your system resources to run multiple operating virtual boxes in your Laptop/Desktop systems. You just need to follow the simple steps which I had done in my experiment: Prerequisites for Kubernetes Cluster Creation Download latest Vagrant Download latest version of Oracle VirtualBox System resources requirements on VirtualBox 2 GB for each node 2 cores CPUs for each node Here I have don this expeiment on my Windows 7 laptop. You could do same on any Windows higher version as well. Total 3 VMs will be created under a group named as - "Kubernetes Cluster" as defined in Vagrantfile. Infrastructure as a Code: Vagrantfile  The Vagrantfile will be composed w...
