• Created Clusters using Kubernetes, Kubectl and worked on creating many pods, replication controllers, services, deployments, labels, health checks and ingress by writing YAML files.
• Used Kubernetes for Orchestration and configured Kubernetes master which in turn uses API objects to get the desired state for the Cluster's. Also created PODS which encapsulates an application container or more container's, storage resources and unique network IP to govern the shared resources.
• Created Ansible playbooks to automatically install packages from a repository, to change the configuration of nodes and to deploy new builds. Configured the Ansible playbooks with Ansible Tower so that other users can run them with just a push of a button.
• Collection of Build metrics and its Test cases from Jenkins to show case as visualization in Kibana dashboard using ELK.
• Deployed and configured JIRA on hosted instances for issue tracking, workflow collaboration and tool-chain automation.
• Implemented the use of Nagios tool and keynote for monitoring and analyzing the network loads on the individual machines by enforcing custom Nagios monitoring, notifications and dashboard to exhibit various metrics using Shell Scripting.
• Diagnosing & Troubleshooting the Linux/Unix servers, network connections, examining raw network traffic nmap, netstat, lsof, arp, Ip, ifconfig, iwconfig, dig, host, tcpdump, route, traceroute.
