  • You like deploying infrastructure, probably in a cloud environment, but you don’t want to push a bunch of buttons in their web interface, so you use Terraform to declaratively define the things you want, and it goes and builds them for you. Super useful for when you need to build resources often, to detect and correct config drift, and get started down the path of Infrastructure as Code.










  • Couple questions:

    • What’s your ISP at home?
    • What’s the ISP of the remote IPv6 server?
    • Are the other networks you’ve tried from the same or different?

    I’d start with traceroute and see how far your IPv6 traffic gets before it fails. It could very well be some peering or routing issue between some of the ISPs in between you and wherever that IPv6 address lives. If this ends up identifying where the traffic dies, a lot of the tier 1 ISPs have BGP looking glass servers so you can get an idea of what they know about that subnet.





  • Here’s what I did for humidifiers in my house:

    • Dumb, analog-controlled humidifiers (like with the knobs, no digital displays, buttons, modes, etc)
    • Local control smart plug (Tasmota flashed Sonoff S31 in my case, but it can be anything)
    • Humidity sensor (I use the Zigbee Aqara ones)
    • Create a Generic Hygrostat entity

    Now you’ve got a smart humidifier in Home Assistant. You can set the desired humidity, and when the sensor detects it’s below this, it’ll kick on the smart switch. When it passes the threshold, it’ll turn off. It’s been great! My humidifiers shut off when the water level drops, so I can even use the power monitoring in the Sonoff switch to send me a “low water” alert when the humidifier should be running, but it’s drawing no power!





  • I haven’t used Docker Swarm (I have barely used Docker Compose), but I have run a couple on-prem Kubernetes clusters (at my house and for clients at my day job) and cloud Kubernetes clusters, so I can speak to how complex it is it set up and run.

    My background is systems administration, engineering, IT, and now DevOps. I’ve been using Linux since Ubuntu 6.06.

    I set up my Kubernetes cluster with kubeadm because I wanted to learn, and it took me about a weekend to get my single master, two worker cluster up and running. I think you could probably do this using k3s much faster and have less learning curve (you don’t have to care as much about Container Network Interfaces, for example, because k3s makes that decision for you.)

    There is a lot of documentation out there on Kubernetes. Helm as a “package manager” (really a templating engine) can be nice if the software you want to deploy has a Helm chart that is well written. Writing your own Helm charts can be a learning process, I’ve modified some but not written one from scratch yet.

    Kubernetes releases new versions about quarterly. I’ve done several upgrades on my primary home cluster over the course of the past 2 years and they’ve been pretty smooth, about an hour of time investment total each. And remember, I’m on the more nerdy and complex flavor of Kubernetes. I think with k3s these would be even smoother and quicker.

    I feel like Kubernetes knowledge is probably more valuable out in the industry if that’s a factor for you. I haven’t come across any Docker Swarm clusters in my DevOps travels, just Kubernetes and some HashiCorp Nomad.

    I’m curious to see what folks say about Docker Swarm. If you have any questions about Kubernetes or running your workload on it, I’d be happy to try to help!
