  • I like this idea in concept. However in most cases failure is mostly due to power loss. So unless these seprate systems have different power sources it might not protect from catastrophy that much.

    As some one who does aquaponics at home. Here are some things ive learned which you might consider.

    • There is a minimum physical footprint that these systems use, especially if you are trying to conserve power. So it might make more sense to max out those systems in that minimum footprint.
    • Different fish can have very different temperature and pH requirements.
    • The pH and temp that the fish like isn’t always what a plant wants.
    • some fish have much greater ranges of pH and temp requirements than others.
    • if indoors, it’s easy for a pest to establish. Like aphids will trive without ladybugs or green lacewings.
    • Vegetables grown in aquaponic systems simply do not taste as good as vegetables grown in soil. Often they are lacking flavor.
    • something about the water in an aquaponic system is excellent for propagation from plant cuttings.

    For these reasons, I use aquaponics more as a backup and complimentary grow system to my no till regenative garden. Having an indoor system is great in the winter if you want leafy greens or to proprpgate trees for the next season.





  • In TBD, it’s not a “release” until its production ready. The methodology and philosophy doesn’t prevent you from developing multiple feature branches at once or even deploying a work in progress feature branch to a dev environment.

    All TBD requires in that case is once the feature branch is production ready, it’s merged to the trunk. You may need to add a feature toggle if there are multiple release like for different architectures. And you also might benefit from using git tags and deploying to production from a git tag instead of the most recent commit on a branch.

    Exactly what you need to do is going to depend on the project’s exact needs but TBD is totally possible in that example.






  • If you are dipping toes into containers with kvm and proxmox already, then perhaps you could jump into the deep end and look at kubernetes (k8s).

    Even though you say you don’t need production quality. It actually does a lot for you and you just need to learn a single API framework which has really great documentation.

    Personally, if I am choosing a new service to host. One of my first metrics in that decision is how well is it documented.

    You could also go the simple route and use docker to make containers. However making your own containers is optional as most services have pre built ones that you can use.

    You could even use auto scaling to run your cluster with just 1 node if you don’t need it to be highly available with a lot of 9s in uptime.

    The trickiest thing with K8s is the networking, certs and DNS but there are services you can host to take care of that for you. I use istio for networking, cert-manager for certs and external-dns for DNS.

    I would recommend trying out k8s first on a cloud provider like digital ocean or linode. Managing your own k8s control plane on bare metal has its own complications.




  • I would say that if you are going to host it at home then kubenetes is more complex. Bare metal kubernetes control plane management has some pitfalls. But if you were to use a cloud provider like linode or digital ocean and use their kubernetes service, then only real extra complexity is learning how to manage Kubernetes which is minimal.

    There is a decent hardware investment needed to run kubernetes if you want it to be fully HA (which I would argue means it needs to be a minimum of 2 clusters of 3 nodes each on different continents) but you could run a single node cluster with autoscaling at a cloud provider if you don’t need HA. I will say it’s nice not to have to worry about a service failing periodically as it will just transfer to another node in a few seconds automatically.




  • You should try out all the options you listed and the other recommendations and find what works best for you.

    I personally use Kubernetes. It can be overwhelming but if you’re willing to learn some new jargon then try a managed kubernetes cluster. Like AKS or digital ocean kubernetes. I would avoid managing a kubernetes cluster yourself.

    Kubernetes gets a lot of flack for being overly complicated but what is being overlooked with that statement is all the things that kubernetes does for you.

    If you can spin up kubernetes with cert-manager, external-dns, and an ingress controller like istio then you got a whole automated data center for your docker containers.
