I mean and this is a weird idea, you could use Kubernetes and create a multi node cluster. the idea is that you would create a storage volume that is shared and sharded across all nodes in the cluster and then when one system fails, you can shift the traffic(using Ingress) to the other node where the container will then start to rebuild. It's a pretty complicated system but you can try that. You do need some basic concepts of server administration and configuration though.

Ali: Wow. Wait. Okay, so you really do everything. And something that was super interesting to me that you just said was that you studied and learned everything. You were building your own training plans and things like that. And I want to take this back to coding a little bit. And say you're talking to me here. You are literally talking to me. And right now, I'm trying to dive into Kubernetes. It's very overwhelming, and there's so much to it. So if you were in my shoes, how would you approach this problem? Because when you approach a new subject, new world, there are ways that you approach the problem to learn. So what does your approach generally look like?

Doorbell Chime on HomePod
1 project | reddit.com/r/HomeKitAutomation | 21 Nov 2021
You know what, you are right. There isn't an "easy" way to do it. When I installed home assistant on my Pi, I actually just opted for a supervised instance running in Docker. Which IS supported. But is like, running home assistant on hard mode if you don't know how Docker works :) (waiting for it to come to Kubernetes for the real fun to begin.)

Nginx – The Architecture of Open Source Applications

> As a relatively young dev, the idea of a "web server" as a standalone binary that serves your application (vs a library that you use to write your own "server") feels strange.
In my eyes, the ideal setup is one that's layered: where you have an ingress that's basically a load balancer that also ensures that you have SSL/TLS certificates, enforces rate limits, perhaps is used for some very basic logging, or can optionally do any URL rewriting that you need. Personally, i think that Caddy (https://caddyserver.com/) is lovely for this, whereas some people prefer something like Traefik (https://traefik.io/), though the older software packages like Nginx (https://nginx.org/en/) or even Apache (https://www.apache.org/) are good too, as long as the pattern itself is in place.
Then, you may additionally have any sorts of middleware that you need, such as a service mesh for service discovery, or providing internal SSL/TLS - personally Docker Swarm (https://docs.docker.com/engine/swarm/) overlay networks have always been enough for me in this regard, though some people enjoy other solutions, such as Hashicorp Consul (https://www.consul.io/), or maybe something intended for Kubernetes or other platforms that you already may be using, like Linkerd (https://linkerd.io/).
Finally, you have your actual application with its server. Personally, i think that the web server should be embedded (for example, embedded Tomcat with Spring Boot) or indeed just be a library that's a part of the application executable, as long as you can update it easily enough by rebuilding the application - containers are good for this, but aren't strictly necessary, since sometimes other forms of automation and packaging are also enough.
The reason why i believe this, is because i've seen plenty of deployments where that just isn't the case:
- attempts to store certificates within the application, each application server having different requirements for the formats to be used, making management (and automation) of renewal a total nightmare

Service discovery — Traditionally provided by platforms like Netflix Eureka or Consul.
1 project | reddit.com/r/PrometheusMonitoring | 11 Sep 2021
For discovery outside of Kubernetes, you can use whatever your configuration management database is to generate the discovery configs. But you might want to look at Consul. The down side to using discovery scripts is the monolithic update lag. I used to have a medium sized setup with Chef and Nagios. It took something like 5 minutes just to run one config cycle. As we transitioned to Prometheus we cut the cycle down to a couple minutes, because we had smaller targeted configs.
HashiCorp Consul: What's the catch?

Harbormaster: The anti-Kubernetes for your personal server

> There is gap in the market between VM oriented simple deployments and kubernetes based setup.
In my experience, there are actually two platforms that do this pretty well.
First, there's Docker Swarm ( https://docs.docker.com/engine/swarm/ ) - it comes preinstalled with Docker, can handle either single machine deployments or clusters, even multi-master deployments. Furthermore, it just adds a few values to Docker Compose YAML format ( https://docs.docker.com/compose/compose-file/compose-file-v3... ) , so it's incredibly easy to launch containers with it. And there are lovely web interfaces, such as Portainer ( https://www.portainer.io/ ) or Swarmpit ( https://swarmpit.io/ ) for simpler management.
Secondly, there's also Hashicorp Nomad ( https://www.nomadproject.io/ ) - it's a single executable package, which allows similar setups to Docker Swarm, integrates nicely with service meshes like Consul ( https://www.consul.io/ ), and also allows non-containerized deployments to be managed, such as Java applications and others ( https://www.nomadproject.io/docs/drivers ). The only serious downsides is having to use the HCL DSL ( https://github.com/hashicorp/hcl ) and their web UI being read only in the last versions that i checked.
There are also some other tools, like CapRover ( https://caprover.com/ ) available, but many of those use Docker Swarm under the hood and i personally haven't used them. Of course, if you still want Kubernetes but implemented in a slightly simpler way, then there's also the Rancher K3s project ( https://k3s.io/ ) which packages the core of Kubernetes into a smaller executable and uses SQLite by default for storage, if i recall correctly. I've used it briefly and the resource usage was indeed far more reasonable than that of full Kubernetes clusters (like RKE).
What Is a Service Mesh, and Why Is It Essential for Your Kubernetes Deployments?
2 projects | dev.to | 17 Aug 2021
With multiple services running, it’s hard to discover where they’re located. The dependencies between multiple services are not always easily found, and new services may be deployed with a new dependency on an older service. Those services can be deployed anywhere in the infrastructure, so what you need is a Service Discovery service. There are plenty available, such as Netflix Eureka or HashiCorp Consul.
Request routing for horizontally scaled services

The myriad of request processing middlewares does not end here - there is also the very trendy topic of service meshes that we could cover, but I choose to leave that as an exercise to interested readers, as it is a rapidly evolving and complex space (see: Istio, linkerd, Consul, Tanzu, etc).
