We thought of creating a single devops group as Telegram have no major roadblock in adding a huge list of people. But felt to have different groups for different major DevOps tools. The existing WhatsApp groups invite links are disabled as we see many spammers spamming the groups. It’s cumbersome to manage as we have to ban spammers from different groups, create a new group after we fill up 255 group members and no proper administration controls. We later realised that WhatsApp is not for large groups where people can reach 255 with ease on sites like us. Some of the disadvantages prompted us to move to telegram as below. The limit in the number of people joins in a group. No anti spam mechanism like disable new user for a certain time. WhatsApp groups die as old people just stay there and no new questions asked after a certain number of moths. No pinning of messages No special privileges of the owner/admin of the group. No bot support on free WhatsApp. All these limitations prompted us to create new telegram groups. Please feel free to leave in comments if you require a new group for a specific DevOps tool. We will see if it really worth to...

How to use ohai/chef-shell to get node attributes

In this post, we will see two excelent tools to get details on system properties within the Chef ecosystem. Ohai is a tool to collect system information and other information for Chef configuration management tool. This information is used to populate in cookbooks before they compile and execute when check client runs on the chef node. Suppose you want to set some swap size depending on swap details are set or not. The chef will never know what the swap size is, it depends on ohai to collect these system details. This is similar to Factor in Puppet, setup module in Ansible. How to access attributes using Ohai? The simplest way to access system information on the node is just to type ohai on chef-node.
