Ansible VS rqlite

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.

Seems like you could do the same with rqlite [1], since SQLite supports JSON.

I found simple distributed RQlite https://github.com/rqlite/rqlite based on raft and sqlite. How hard is to add it?

rqlite[1] creator here, happy to answer any questions. rqlite also supports read-only nodes, which can also help with reads at the "edge". It probably wouldn't scale to 100s of nodes, it is an option.

"rqlite supports adding read-only nodes. You can use this feature to add read scalability to the cluster if you need a high volume of reads, or want to distribute copies of the data nearer to clients – but don’t want those nodes counted towards the quorum. These types of nodes are also known as non-voting nodes."
