Nomad VS SaltStack

In previous post, we discussed creating a basic Nomad cluster in the Vultr cloud. Here, we will use the cluster created to deploy a load-balanced sample web app using the service discovery capability of Nomad and its native integration with the Traefik load balancer. The source code is available here for the reference.

Nomad is really awesome!

I only heard of this today, but it looks really interesting. It seems to finally get Kubernetes a bit closer to something like https://www.nomadproject.io/ in terms of complexity to install and operate.

In the rapidly evolving landscape of container orchestration and management, two prominent players have emerged: Kubernetes and HashiCorp's Nomad. While Kubernetes has gained widespread adoption and popularity, Nomad provides a compelling alternative that stands out for its simplicity and efficiency. In this blog post, we'll explore the advantages of using Nomad over Kubernetes and why it might be the right choice for certain use cases.

I can't discern how many are just those "dependabot" bumps but the 1400 forks show some are active https://github.com/hashicorp/nomad/forks?include=active&page... including CircleCI who I would think have a stake in a libre Nomad https://github.com/circleci/nomad/tree/circleci/release-1.5....

Now maybe their goals don't align with the community, and/or they don't want to be in the maintainer business for such a project, but better than nothing

Could this be a solution? nomad

It worth noting that Nomad UI(a official web admin panel) has log tailing utility built-in so maybe partial work has already been done. The developers may have other concerns.

While I do understand the reasoning in their FAQ on the subject (https://www.hashicorp.com/license-faq). I however failed to noticed those intentions in their license text (https://github.com/hashicorp/nomad/commit/b3e30b1dfa185d9437...).

Specifically the part in FAQ which says "internal production use is fine", but then license says that "non-production use only" and then "You may make production use of the Licensed Work, provided such use does not include offering the Licensed Work to third parties on a hosted or embedded basis which is competitive with HashiCorp's products.".

IANAL, but even to me this statement is full loopholes. WHO do we consider 3rd party? WHAT do we consider "hosted or embedded basis"? WHEN do we consider it "competitive with Hashicorps products"?

My repeated tests show that when an allocation that is using a volume is deallocated, nomad doesn't release the volume. So, it is inaccessable to the next allocation.

In the new style, when the tag is longer than 20 characters, an end of tag string is appended to the tag given by the string constant TAGEND, that is, two line feeds '\n\n'. When the tag is less than 20 characters then the tag is padded with pipes "|" out to 20 characters as before. When the tag is exactly 20 characters no padded is done. source: https://github.com/saltstack/salt/blob/master/salt/utils/event.py

SaltStack

One thing that really irks me about Salt, though, is that they are very slow to fix bugs. My Salt states are littered with workarounds for bugs that have been open for multiple years. Even in basic things, like ssh authorized_keys management. Other than bug velocity, though, I've been pretty pleased with Salt.

Here are several related GitHub issues: - https://github.com/saltstack/salt/issues/54791 - https://github.com/saltstack/salt/issues/57541 - https://github.com/saltstack/salt/issues/16089

It's definitely some sort of AI script. Not this exactly, but something working off Python or scripts of thar nature. https://github.com/saltstack/salt
