Sinatra VS Ansible

Compared to Ruby on Rails, a full-stack web framework, Sinatra is a very lean micro-framework originally developed by Blake Mizerany to help Ruby developers build applications with "minimal effort".

Let's say I have the simplest single-file Sinatra app. The hello world on their homepage will do. I want to run it under Apache with Phusion Passenger, AKA mod_rails.

Sinatra is the oldest competitor of Rails. Although it's not that popular anymore, it's still used in some simple and performance focused services.

Sinatra is fine as long as you have a small number of routes, because its router is O(n): https://github.com/sinatra/sinatra/blob/ac5404dbd897a4b3c5b3921d2f89fecd3b540ed3/lib/sinatra/base.rb#L1008-L1010

Ansible v2.16

Ansible is a tool used to help manage software automation processes, configuration management across machines, deployment as well as remote execution of commands and scripts. In sports, Ansible operates as the coach of your team by providing strategies (playbooks), and actions, and ensuring the smooth execution of tasks across your infrastructure, just like a coach guides and directs players (Servers)during a game.

They support for-if from python, too: https://jinja.palletsprojects.com/en/3.1.x/templates/#loop-f... but I haven't tried the "recursive" keyword to know if ansible supports that. I say "ansible supports that" because they don't just drop jinja2 into ansible and call it a draw, they have a bunch of custom execution integrations: https://github.com/ansible/ansible/blob/v2.16.3/lib/ansible/...

To manage a VM, you can use something as simple as just manual actions over SSH, or can use tools like Ansible, Hashicorp's Packer and Terraform or other automations. For an app where there is minimal load and security/reliability concern, VMs are still a great option that provide a lot of value for the buck

In this article's context, it is simply a tool that provides a declarative way to automate your machine/OS to configure the development machine as you want (install package, modify the configuration, etc). Examples of these tools are Ansible, Puppet, etc.

Now we're getting more tangential, but for years, Ansible releases were named for Van Halen songs (see old Changelog here: https://github.com/ansible/ansible/blob/v1.8.4/CHANGELOG.md)

In the lab to follow, we'll quickly provision a 3-node kubeadm cluster (1 master, 2 workers) on the cloud provider of your choice using an automation stack comprised of OpenTofu and Ansible, then deploy Rook Ceph using the official Helm charts and confirm that we are now able to successfully create CSI volume snapshots from PVCs by reusing the MinIO example from our last article.
