Deployment of RHOSP 16.1 with for Virtualized Controllers In this blog we demonstrate to deploy overcloud controllers as virtual machines in a Red Hat Virtualization cluster. This article might provide the audience with additional insights and tips that will help to succeed in deploying Red Hat OSP 16.1 with virtualized controller. We are building private cloud for “PoC” and documenting best practices for RHOSP 16.1 deployment gained through our experience.…
RHOSP Openstack Deployment 16.1
Its been 4 weeks now we have started deploying RHOSP16.1,the latest version of Red Hat Openstack. Through this blog I would like to describe some of the experience we gained. This article might provide the audience with additional insights and tips that will help to succeed.…
Provisioning NFS based Persistent Volume in Kubernetes
Traditionally we have shared storage, across the nodes using NFS/iSCSCI at the operating system level. Kubernetes comes with concept of PV and PVC, lets discuss this briefly before we start deploying NFS and associate with our Kubernetes cluster. Containers are immutable , when container shutdown all the data is lost. This behaviour may not be suitable for some applications like database where application needs to share the data with other…
Deploying And Configuring iSCSI Target
In this post, we will deploy and configure an iSCSI Target Server on CentOS 7.9, then we will attach this storage to Kubernetes Cluster in Kubernetes section. My environment: I am running Centos 7.9 VM on a ESXI 6.5 platform, running on HP DL380 server. Other VM’s that are cohabitating with the scuzzy VM, are 3 Kubernetes worker nodes,1 Kubernetes Master node, 1 Ansible Master node, Eveng and a…
Working With Linux, Basic Commands
Recently I was working on a Nokia’s LTE & UMTS Automated Operations and Recovery (AOR), a product which simplifies service operations by automating network supervisory activities . I had a team from diverse background like transmission,RF,Core,Networks,Java developers,Database and our task was to test Linux based opensource application which obviously needed good knowledge of Linux CLI. Linux Command-Line provides a richer experience in terms of speed and expressiveness. Linux Operating system…
Working With Kubernetes
Kubernetes is an open-source platform that helps you deploy, scale, and manage resources across multiple containers. A Kubernetes cluster would generally have a master node and several worker-nodes or Minions. The worker-nodes are then managed from the master node, thus ensuring that the cluster is managed from a central point. Master Node API Server – It provides kubernetes API using Jason / Yaml over http, states of API objects are…
openstack-neutron-networking_part2
Neutron is a an Openstack module which takes care of networking using the Plug-ins.It consists of the following Logical Elements depicted below in Figure 01. We will use the below figures 01 and 02 as reference through out this blog. Figure01 Figure02 1) Neutron Server ( API Server): It receives the API calls and directs them to Neutron Plugins.Neutron-server is basically a Python daemon that provides the the…
Troubleshooting_Openstack_Part1
My Use Case: Troubleshooting “No valid host was found” Error: Failed to perform requested operation on instance “Waghoba”, the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.]. Troubleshooting Openstack is not a easy Job. Logs, logs and more logs , all you need to look at those voluminous log at different locations. Typically when encountered with “No Valid Host Found ” error you need to check the filters. In this example the error was caused due to Insufficient Disk ” space or inappropriate disk partition. Lets see how I…
Beryllium ODL SDN Controller Installation
Let us install the Beryllium ODL SDN Controller . In my SDN lab setup I have 3 Dell servers , One Vcenter and a Windows Domain controller ADS. There are 5virtual machines spinning 3 Controllers (Brocade , HP VAN and Opendaylight) and 2 Openflow simulators Mininet and Estinet. We start installing the Beryllium ODL SDN Controller on server Saraswati having IP address 192.168.0.75. The installation has 3…
Implementing Brocade OF/Netconf Vyatta Router
In this episode I am installing the Vrouter as a virtual machine on my ESXI server 192.168.0.25. We will configured this router to communicate with the Controller over the South bound interface using Netconf protocol. Lets go ahead and create a Virtual machined for the Netconf complaint router Activating the license [edit] vyatta@vyatta# set system name-server…
