Reading Time: 2 minutes A few days back, we got the requirement that we need to parse an HTML table through shell script and generate a report based on the contents of the table. I tried many things and after much brainstorming created a shell script that parses the HTML tables into a CSV file. I will try to explain each and every step of this script.

It is easy to manage due to the rigidity of the model – each phase has specific deliverables and a review process. But, it was painstakingly slow; the builds took a long time to build and deploy. But in this world of heavy Continue Reading

Reading Time: 3 minutes In this post, we will use Ansible to and set-up an Apache Cassandra database cluster. We will use AWS EC2 instances as the nodes for the cluster. Creating a cluster manually is a tedious task. We have to manually configure each node and each node must be correctly configured before starting the cluster.With Ansible, we can automate the task and let Ansible handle the configuration Continue Reading
Reading Time: 5 minutes Managing configurations of multiple servers and environments are one of the significant uses of Ansible. But these configuration files may vary for each remote servers or each cluster. But apart from some few parameters, all other settings will be same. Creating static files for each of these configurations is not an efficient solution and it will take a lot more time and every time a Continue Reading

Ansible lets us control and configure nodes from a single machine. It is different from other management software in a way where Ansible uses SSH infrastructure and uses push mode and the configuration is pushed from a master machine to nodes. Ansible achieves all Continue Reading
