Rundeck VS kubernetes

Have a look at rundeck.org

Firstly, I tried Rundeck and Apache Airflow. They are complete overkill for what I want to do. Then I found Cronicle which is light enough, besides it can pull double duty as a general purpose scheduler.

Yesterday we posted a Security Advisory to Github for a critical vulnerability in Rundeck Community and Rundeck Enterprise Docker images, versions 4.0 and earlier. Those Docker images contained a pre-generated SSH key pair in the default file path. If that key was used to configure SSH access to hosts, they would allow access to anyone with the exposed private key.

Never used it myself (we're currently working on deploying Tower) but I've heard that Rundeck is the goto for your exact use case: "Tower, but less heavy". I looked at it when evaluating for my current job and it looks like a good middle of the road solution and looks way easier to deploy than AWX. The tradeoff is that since it's not custom built for Ansible you can automate lots of other things with it (like just bash scripts and the like) but you get less of the Ansible-specific integrations and tooling that Tower offers.

Hi! This fix solves the bug, is ready to be included in the next release. Regards.

There is already an open GitHub issue on this, but I wanted to mention it here as it can cause some nasty surprises for those unaware.

Kubernetes and Helm for deployment

3 .Learn about containerization and orchestration tools such as kubernetes and docker

It is cross-platform and therefore able to be installed on any of Windows / Mac / Linux. This must be one of their advantages. Supposed that some files defining a virtual machine or a pod (of Kubernetes) for grouping ones are delievered, we can develop on the same virtual enviroment with defferent workstations.

Docker is a DevOps containerization service that separates your code from the infrastructure it depends on. Docker is often coupled with Kubernetes, which helps you rapidly deploy, scale and manage your containers. Together, they administer rapid software delivery and take care of its scaling.

Kubernetes is an Open Source container orchestration system. Kubernetes' API provides a uniform control layer for managing containerized services. There is a lot of great material available that explains what Kubernetes is. See Further Reading at the end for some suggestions.

If it's not something you can figure out from kubernetes.io, then its not something that you have to worry about being on the test.

Intermediate knowledge of Flux, Kustomize and K8s

There's been a highly annoying kubectl port-forward heisenbug open for several years which smells an awful lot like one of these dark Go network layer corners. You get a good connection establish and some data flows, but at some random point it decides to drop. It's not annoying enough for any wizards to fix.

Well, like I said, I'm building a harvester/k8s cluster. So, the idea being that if one of the machines is busy or goes down, an other part of the cluster can pick up the slack. Basically, the 'Voltron' of computing, many pcs come together to form a more 'powerful' system. I can do this with any pc, but minis are good for homelabbing because they're cheap, don't take that much space, aren't that power hungry, and they still are powerful enough to run 90% of anything I throw at it, that isn't graphic intensive.
