-## Learn
-
-First and foremost, this demo is a great way to learn about the Kubernetes environment and the components that have to work together. Building and running the system is the best way to gain practical experience with the challenges that come with working with so much complex technology.
-
-* Kubernetes is complex
-* Ceph is complex
-* Networking is complex
-* Security is complex
-
-Putting them all together is even more challenging. Keeping things running under various pressures and stresses of usage is another challenge. Diagnosing and fixing problems is a third. Our demo system needs to reflect a realistic production system, even if it is at the small end of things in terms of size.
-
-The demo system is a safe place to try things. Anyone who really wants to learn can follow the procedures to set up a new system, and help care for the system we have running.
-
-Also, this is a great basis for experimentation. Start from the known stable system and see what happens with various changes. Try an upgrade either by hand or using the Koor Version Manager (someday). Try adding storage capacity. See what happens when a node is shut down, then restored. There is no limit to the number of real-world situations we can try using our demo system.
-
-
-## Showcase
-
-One of the most important uses of our demo system will be...wait for it...to *demonstrate* how KSD helps manage Rook Ceph data storage. We will use the system to show what KSD can do. We will start with a simple demo since KSD is just getting started. Over time, the demo will become more elaborate and impressive.
-
-This may be the single most important factor in convincing people to adopt KSD.
-
-
-## Share
-
-Closely related to learning and experiments is our ability to set up various use cases for Ceph-managed data. The configuration for each use case can be copied from the demo system into our Knowledge Base. We can also include configuration pattern in KSD that customers can apply to their environments with a click or two. Easy setup, quick tuning.

-# Demo system - Dave's manual implementation notes
-
-These notes capture Dave's attempt to set up a demo system for shoring Koor Rook Ceph in Kubernetes. The [overview](index) defines the target system. As with all plans, they go bad at the first sign of trouble. The discovery of what worked is documented here.
-
-A word of caution, the fact that something "worked" in that I was able to continue with the next step does not mean that I made the best decisions. A big part of the this exercise is to learn how all of this works, and there are a lot of moving parts.
-
-Basically, apply your own judgement and critical thinking, and experiment with alternate approaches to everything.
-
-
-## Target requirements
-
-For this exercise, I am attempting to set up a minimum environment that would be suitable for production. That means I will not use minikube, favoring kubeadm and other production-grade tooling. The system will use multiple hosts. However, on Hetzner where this is being provisioned, there are limits of 10 vCPU and 8 hosts. The minimum number of CPUs per K8s node is 2, so we are limited to 5 hosts. Given that constraint we will start by setting up:
-
-* 1 control plane node
-* 1 worker node
-* 3 storage nodes
-
-This system would not be suitable for mission-critical use. For example, we recommend 4 storage nodes as a minimum to allow for recovery from a single node failure. However, this will be a good starting point to expand on by by adding more nodes and capacity: CPUs, memory, drives, etc.
-
-
-## General approach
-
-After 3 or 4 attempts, a basic pattern for setting things up by hand is emerging.
-
-1. Provision machines, or define what to provision
-   1. We are using Hetzner for VM hosting by the minute. That's a good approach for temporary environments. The smallest host with 2 CPU is about 3.5 Euro per month. I don't think it gets much cheaper.
-   2. We should use a provisioning tool, like [Terraform](https://www.terraform.io/). In fact, if we use KubeOne to set up the Kubernetes cluster, it uses Terraform under the hood for host provisioning. KubeOne integrates with AWS, CGP, Hetzner and others.
-   3. Provisioning by hand works, too.
-2. Set up pre-requisites for K8s
-   1. Each host needs a container runtime: containerd or CRI-O
-      1. Ubuntu and Debian have packages for containrd. Install that and configure according to instructions.
-   2. Set up networking, CNI, plugins, etc.
-3. Install K8s and set up a cluster
-   1. TBD
-4. Use Koor Operator to set up data storage -- it should be that easy if the rest was done right
-   1. TBD
-
-
-## Manual installation on Ubuntu
-
-### Provisioning servers (VMs) on Hetzner
-
-Hardware and network
-
-* The minimum spec is CPX11: 2 vCPU, 2GB RAM, 40GB local SSD, 3.85 Euro / mo
-  * Select Ubuntu 22.04 (or choose a different OS, but you will need to make adjustments as you go through these instructions)
-  * Small additional charge for public IPv4
-  * Worth thinking about what needs access from outside, limitation on number of public IPs
-* Drives are provisioned separately and attached to a host
-  * Available in 10 GB increments up to 10 TB
-  * Need 1 per storage node to start. Expand to 2 per node once things are running.
-  * They come with a file system: XDF or EXT4 -- will need to remove that before setting up Ceph
-* Also available: load balancers, floating IPs, networks (e.g., private between nodes might be handy), firewalls and security keys.
-
-
-### Logging in
-
-These tips might save you some time and frustration when logging in to your hosts.
-
-1. As you are provision a server, you can created an SSH key or use an existing key. Do this: create one, then use the same one for all hosts. The private side of that key goes on your local machine.
-2. You can log in as root over SSH. By default, root does not allow login/password over SSH. [Directions are here](https://docs.hetzner.com/cloud/servers/getting-started/connecting-to-the-server).
-   1. If you ever need to reset a password, do it from the Cloud Console. [Resetting the password](https://docs.hetzner.com/cloud/servers/getting-started/rescue-system)
-3. Then you have to set up local SSH stuff
-   1. ~/.ssh/config needs an entry like this:
-
-```sh
-Host hetzner.com
-  HostName 5.78.69.87
-  User root
-  PreferredAuthentications publickey
-  IdentityFile ~/.ssh/hetzner-id_ed25519
-```
-
-You probably have at least github.com in there as well, since you are signing your commits, right? Just append to what is there.
-
-Then you can connect with: `ssh hetzner.com`
-
-The first time you connect to a server, you'll want to accept the host fingerprint.
-
-
-### Set up containerd
-
-* provisioned 4 VMs: 1 control plane and 3 data nodes
-* setting up all at the same time
-* Ubuntu 22.04
-
-Setting up each machine with:
-
-* `apt update`
-* `apt upgrade`
-* reboot: `shutdown -r now`
-* `apt install containerd`
-* `curl -L https://raw.githubusercontent.com/containerd/containerd/main/containerd.service -o /usr/local/lib/systemd/system/containerd.service`
-  * edit and change 
-    * `ExecStartPre=-/usr/sbin/modprobe overlay`
-    * `ExecStart=/usr/bin/containerd`
-* `systemctl daemon-reload`
-* `systemctl enable --now containerd`
-* `mkdir -p /etc/containerd`
-* `containerd config default > /etc/containerd/config.toml`
-* `vi /etc/containerd/config.toml`
-  * change `SystemdCgroup = true`
-* restart: `systemctl restart containerd`
-
-Regarding cgroup drivers, Ubuntu uses systemd. Looks like we don't need to worry about them since k8s v1.22 if using kubeadm, which we are. 
-
-### Install CNI plugins
-
-```sh
-wget https://github.com/containernetworking/plugins/releases/download/v1.3.0/cni-plugins-linux-amd64-v1.3.0.tgz
-wget https://github.com/containernetworking/plugins/releases/download/v1.3.0/cni-plugins-linux-amd64-v1.3.0.tgz.sha256
-cat cni-plugins-linux-amd64-v1.3.0.tgz.sha256
-sha256sum cni-plugins-linux-amd64-v1.3.0.tgz
-mkdir -p /opt/cni/bin
-tar Cxzvf /opt/cni/bin cni-plugins-linux-amd64-v1.3.0.tgz
-```
-
-### How to use containerd
-
-For reference: [containerd basic usage](https://github.com/containerd/nerdctl#readme)
-
-
-### Install kubeadm, kubectl, kubelet
-
-Use the following commands to:
-* Make sure dependencies are in place.
-* Get Google Cloud signing key. 
-* Add K8s apt repo. 
-* Update apt package index, install kubelet, kubeadm and kubectl, and pin their versions.
-
-```sh
-apt-get update
-apt-get install -y apt-transport-https ca-certificates curl gpg
-curl -fsSL https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-archive-keyring.gpg
-echo "deb [signed-by=/etc/apt/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
-sudo apt-get update
-sudo apt-get install -y kubelet kubeadm kubectl
-sudo apt-mark hold kubelet kubeadm kubectl
-```
-
-### Forwarding IPv4 and letting iptables see bridged traffic
-
-```sh
-cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
-overlay
-br_netfilter
-EOF
-
-modprobe overlay
-modprobe br_netfilter
-
-# sysctl params required by setup, params persist across reboots
-cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
-net.bridge.bridge-nf-call-iptables  = 1
-net.bridge.bridge-nf-call-ip6tables = 1
-net.ipv4.ip_forward                 = 1
-EOF
-
-# Apply sysctl params without reboot
-sysctl --system
-```
-
-Verify br_netfilter and overlay are loaded:
-
-```sh
-lsmod | grep br_netfilter
-lsmod | grep overlay
-```
-
-output looks like:
-
-```
-br_netfilter           32768  0
-bridge                307200  1 br_netfilter
-overlay               151552  0
-```
-
-Verify that the net.bridge.bridge-nf-call-iptables, net.bridge.bridge-nf-call-ip6tables, and net.ipv4.ip_forward system variables are set to 1 in your sysctl config by running the following command:
-
-```sh
-sysctl net.bridge.bridge-nf-call-iptables net.bridge.bridge-nf-call-ip6tables net.ipv4.ip_forward
-```
-
-output looks like:
-
-```
-tables net.ipv4.ip_forward
-net.bridge.bridge-nf-call-iptables = 1
-net.bridge.bridge-nf-call-ip6tables = 1
-net.ipv4.ip_forward = 1
-```
-
-### Initialize cluster - starting with the control plane node
-
-On the control plane node, initialize a cluster with: `kubeadm init`
-
-**Important: Worker nodes will need to join this cluster, so the initialization command and procedure is different.**
-
-When it's done, you should see instructions like the following:
-
-```
-To start using your cluster, you need to run the following as a regular user:
-
-  mkdir -p $HOME/.kube
-  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
-  sudo chown $(id -u):$(id -g) $HOME/.kube/config
-
-Alternatively, if you are the root user, you can run:
-
-  export KUBECONFIG=/etc/kubernetes/admin.conf
-
-You should now deploy a pod network to the cluster.
-Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
-  https://kubernetes.io/docs/concepts/cluster-administration/addons/
-
-Then you can join any number of worker nodes by running the following on each as root:
-
-kubeadm join 5.78.71.223:6443 --token dnwiob.gxlqqsj8xf1x68ne \
-	--discovery-token-ca-cert-hash sha256:bf3ecf6b38976838dc7b0092a2925bf0defa7891815b29a623896c15de2bee38
-```
-
-The instructions suggest to run the cluster as a regular user, which makes sense for security reasons. You can also run as root, since it's easier to get things to work that way. In the long run, better to run as a user with limited permissions.
-
-
-### Install Cilium (or whichever Pod network works for you)
-
-You need to add a pod network for your cluster. [Read about it here](https://kubernetes.io/docs/concepts/cluster-administration/addons/) I liked Cilium the best based on the brief descriptions of what is available.
-
-Options I considered:
-
-* Cilium - looks good: networking, observability, and security solution with an eBPF-based dataplane.
-* Calico - container network and security - open source
-* Multus - for attaching multiple network interfaces -- don't think we need that
-
-* Install Cilium CLI
-
-```sh
-CILIUM_CLI_VERSION=$(curl -s https://raw.githubusercontent.com/cilium/cilium-cli/master/stable.txt)
-CLI_ARCH=amd64
-if [ "$(uname -m)" = "aarch64" ]; then CLI_ARCH=arm64; fi
-curl -L --fail --remote-name-all https://github.com/cilium/cilium-cli/releases/download/${CILIUM_CLI_VERSION}/cilium-linux-${CLI_ARCH}.tar.gz{,.sha256sum}
-sha256sum --check cilium-linux-${CLI_ARCH}.tar.gz.sha256sum
-sudo tar xzvfC cilium-linux-${CLI_ARCH}.tar.gz /usr/local/bin
-rm cilium-linux-${CLI_ARCH}.tar.gz{,.sha256sum}apt 
-```
-
-* Now install Cilium with `cilium install`
-* Verify cilium install using `cilium status --wait`
-  * You should see something like this:
-
-```
-    /¯¯\
- /¯¯\__/¯¯\    Cilium:             OK
- \__/¯¯\__/    Operator:           OK
- /¯¯\__/¯¯\    Envoy DaemonSet:    disabled (using embedded mode)
- \__/¯¯\__/    Hubble Relay:       disabled
-    \__/       ClusterMesh:        disabled
-
-DaemonSet              cilium             Desired: 1, Ready: 1/1, Available: 1/1
-Deployment             cilium-operator    Desired: 1, Ready: 1/1, Available: 1/1
-Containers:            cilium             Running: 1
-                       cilium-operator    Running: 1
-Cluster Pods:          2/2 managed by Cilium
-Helm chart version:    1.13.4
-Image versions         cilium             quay.io/cilium/cilium:v1.13.4@sha256:bde8800d61aaad8b8451b10e247ac7bdeb7af187bb698f83d40ad75a38c1ee6b: 1
-                       cilium-operator    quay.io/cilium/operator-generic:v1.13.4@sha256:09ab77d324ef4d31f7d341f97ec5a2a4860910076046d57a2d61494d426c6301: 1
-```
-
-### Missing last step
-
-The next thing is to start the cluster and apply the config for Cilium. Wasn't able to find an example config file, which blocked me. Basically, I ran out of clues.
-
-So I ordered the course, [Kubernetes Fundamentals (LFS258) - Basics of Kubernetes | The Linux Foundation](https://training.linuxfoundation.org/training/kubernetes-fundamentals/). After setting up my AWS account, the first action in the course is to prep a couple of nodes for K8s. Basically, it went through the same steps I have already learned, but also makes a few of the choices less ambiguous. Instead of Cilium, it uses Calico, but also says Cilium is a great up-and-coming option.
-
-What I learned so far from the course is that everything here is essentially correct and useful as a way to set things up. The course is useful because set-up is just the beginning. There's a lot more to get through, and no point in struggling without guidance.
-
-Also, I will not face the same resouce constraints on AWS. I have already set up a control plane node and one worker node. Now I can repeat the worker node set up to get some data nodes going.
-
-This is the end of the journal for now.
-
-
-## Misc resources
-
-Recent releases of pre-reqs:
-
-* [containerd releases](https://github.com/containerd/containerd/releases)
-* [runc releases](https://github.com/opencontainers/runc/releases)
-* [cni plugin releases](https://github.com/containernetworking/plugins/releases)
-* [config example](https://github.com/containerd/containerd/blob/main/docs/man/containerd-config.toml.5.md)
-  * although you can also get the default from containerd config and pipe that to the file
-
-I thought these generic releases were important before learning that packages are available for containerd. Presumably the packages are tuned for the flavor of Linux. (Perhaps, or maybe they adopt the common version without changing much. I suppose we don't need to worry about that for our demo system.)

 # Demo System Overview
@@ -8,79 +9,96 @@ title: Demo System Overview
 
 We are creating a demonstration system for three major reasons.
 
-1. We need hands-on experience designing, building, and running distributed K8s environments using Rook Ceph for data storage. Typical "Getting Started" guides are insufficient for gaining experience with what our customers have to support.
-2. We need a way to prove out use cases that the KSD supports and to show our work to customers.
-3. We need a way to run meaningful experiments in an environment that can be adapted to match what customers do, or at least follow similar patterns.
+### Gain experience
 
-The environment should support real applications that make use of data. The demo needs to be big enough and configured completely enough that it shows correct patterns -- running 4 or more nodes, spreading pods across nodes, using proper security, etc. On the other hand, we are not trying to discover the outter limits of Ceph or Rook scalability. Cost is still a consideration.
+In order to better empathize with our customers, we need hands-on experience designing, building, and running distributed K8s environments using Rook Ceph for data storage. Typical "Getting Started" guides are insufficient for learning about production situations. Our demo system can help us understand some aspects of what our customers have to do. We can also build our skills so that we provide better support.
 
-When complete, the demo system should be spun up and down through automation. In fact, the more of this kind of automation we put into KSD, but better our chances of selling to big customers.
+### Put Koor software to use
 
-[Demo System Vision](demo-system-mindmap)
+Whenever we release software, our demo system can be the first production-like system to give it a try. We can set up a variety of use cases and situations to put our software through it's paces. Plus, we will want to record videos that show our software's capabilities.
 
+### Run experiments
 
-## Features we want to showcase
+Our demo system should be a great place to run experiments. Maybe we need to research the optimal configuration for a given use case. We can use our stable demo environment and isolate the change we want to explore. Also, we should be able to push things to the limit. Also, we can try out configurations that our customers are using and see if we can find a way to improve throughput or some other dimension.
+
+## Requirements
+
+### Hosting
+
+We run our demo system in the cloud. Koor does not operate a data center, and we need world-wide accessibility. We prefer [Hetzner Cloud](https://www.hetzner.com/cloud) for hosting, with data centers in Europe and USA. Easy to spin up servers and add disks. Low cost -- we can leave it running for quick access and guest users. Lots of Kubernetes tooling knows about it.
+
+### Easy setup / tear down
 
-This a list of specific points that the demo system needs to handle. Let's add everything we can think of to the list. If it gets long, we can organize into sublists. In any case, we will group the requirements into development milestones.
+While we will treat a running demo system like a pet &ndash; caring for it, nurturing it, teaching it new tricks &ndash; we also need a way to spin up new demo environments quickly. It would be normal to have a primary system for customer demos and recordings. We will also want another to ensure that upgrades and other significant changes will work. Plus, if the demo system is to be a basis for experiments, we need a quick way to get started.
 
-1. Include the yaml for setting up the K8s cluster.
-   1. Start with a minimum for production where things work under light-to-medium loads.
-   2. Would be nice to pick from a library of configuration patterns that match common use cases.
-2. Use the latest KSD release to set up Rook Ceph.
-   1. Great if installation is automated.
-3. Add applications that represent what real users will want to do and the data those applications need.
-   1. Some kind of database.
-   2. A CDN serving a static website and its assets: HTML, CSS, Javascript, images.
-   3. A streaming service for video, sound.
-4. Show backup and recovery as one of the features of the environment, with Rook Ceph as the storage for backups.
-5. ...and more... please add more ideas
+When complete, the demo system should be spun up and down through automation. Ideally, we will use GitOps for all demo system setup and changes. While we are setting that up and learning how to use it, we will have to rely on tools and scripts and a lot of keying things in by hand. At a minimum, we need to keep up-to-date instructions about how to install everything we need.
 
+We have a gitops repository, [demo-gitops](https://github.com/koor-tech/demo-gitops). If you work on the demo system, please make sure your efforts are captured there.
+
+### Sufficient resources
+
+The environment will support real applications that make use of data. The demo needs to be big enough and configured completely enough that it shows correct usage patterns -- running 1 or 3 control plane nodes, 4 or more data nodes, spreading pods across nodes for fault tolerance, using proper security, etc.
+
+On the other hand, we are not trying to discover the outer limits of Ceph or Rook scalability. Cost is still a major consideration.
+
+## Features we want to showcase
 
-## System design
+We can categorize the types of features we want to highlight with our demo system.
 
-**Note: This may take many iterations to work out.**
+### Kubernetes, Rook, and Ceph
 
-Here's a diagram of the demo system.
+Sometimes people want to copy something that works. We can have a few different flavors for the different layers of the environment.
 
-![Demo System Design](demo-system-design.drawio.svg)
+1. Show what a normal (albeit small) production set-up looks like, with Kubernetes, Rook and Ceph running. In this case, we can treat Rook and Koor Storage Distribution (KSD) interchangeably. We cover KSD is a different category.
+2. OS: Linux (Ubuntu, Debian, CentOS)
+3. Networking: Calico, Cilium, Multus - these may have an impact on Ceph performance.
+4. CRDs, PVs, PVCs.
+5. Security: SSO, role-based access control, ingress/egress
+6. This is not an exhaustive list.
 
-(This is in draw.io [here](https://app.diagrams.net/#G1Es8ikJ0fN7b4BJiUpxWnaxQPSSkZK5Mg). Ask Dave if you want to collaborate or get a copy.)
+### Koor products
 
-Notes about the diagram:
+1. Koor Data Control Center
+2. Koor Operator
+3. Koor Storage Distribution (KSD)
+4. Koor Version Service
+5. Troubleshooting tools
 
-1. The picture shows a minimum of 7 servers, including 4 servers dedicated to Ceph storage. We recommend customer use 4 nodes so that Ceph can recovery gracefully if any one node goes out.
-2. Each node will have a minimum of 2 drives for basic redundancy. Most systems will have more, but never fewer.
-   1. Storage nodes will always have the same number of drives, so if we add 1 drive, we're adding 4 (assuming 4 nodes).
-3. What is missing from this diagram?
-   1. Alex: If we want to use CephFS (filesystem) or RGW (object storage), it would introduce MDS or RGW daemons to the cluster, not necessarily on all the storage nodes as we would need to scale based on the load, though as always minimum 2 per storage type then for HA.
+### Data usage patterns
 
-Does anything else need to be added to the diagram? Any corrections?
+1. Block storage
+   1. Databases - MariaDB, Postgres
+   2. Recording and streaming apps
+2. Object storage
+   1. S3
+   2. CDN - website artifacts
+      1. Images / videos
+      2. Fonts
+   3. Log files
+   4. Backups
+3. File storage
+   1. ??
 
-**Note: We should remember to adjust the picture as the system evolves. In fact, deviations should start as changes to this design. We should also docuemnt the things we try.**
+### System dynamics
 
-## Implementation details
+The best demonstration will show how the system changes in response to activity and configuration updates. We should have two ways to generate activity:
 
-For short experiments, EC2 on AWS is attractive -- maybe. The per-hour cost is low if you only need the VM for a few hours. However, after a few days, the cost breaks even with the monthly cost of VMs from Hetzner.
+- On demand by using applications and scripts that put data load on the system.
+- Using simulated activity driven by bots.
 
-From what I could tell without spending any money, Hetzner charges for the full month on provisioning. So using a VM for a few hours (just to practice or if the wrong specs are provisioned) would end up wasting money. Granted, it's a small amount per server. Times 6, times how many drives.
+We can be creative. Here are a few ideas for getting started.
 
-Better to get the design right (as least as much as we can figure out) before building.
+1. Run [Mastodon](https://github.com/mastodon/mastodon) - this requires a Postgres database and gives us an interface for "generating" data. Plus we can have fun with it for demos.
+2. Have a bot that adds and removes files from S3 buckets. Could be a short script with some randomness and a set of files to choose from. Set up a cron job to run the script every 5 minutes or so. Set some limits to avoid filling a drive and crashing the system.
+3. Set up a CDN with license-free content. We can use our YouTube videos, download a collection of Google fonts, anything that we are allowed to distribute. Then host a static website or SPA from the CDN.
+4. Other ideas? An example of AI?
 
-And we'll make mistakes, so that's the cost of learning.
+## More information
 
-Some decisions:
+We have a steady endpoint for our running demo system: [demo.koor.tech](https://demo.koor.tech). Ask around for the username and password.
 
-* Provision VMs on Hetzner first.
-  * We can also try AWS or GCP once things are working on Hetzner if we want to compare the hosting experience. Customers will have their own preference for hosting.
-  * Pretty sure we don't want to pay for a bare metal system that we self-host.
-* Let's use Ubuntu 22.04
-  * It's available on Hetzner and AWS, which means it's popular.
-  * It's aligned with Canonical, not RedHat. (I read something about Centos losing support? And other shenanegans.)
-* We will use kubeadm, since we are building a production-style system.
-* We will use CRI-O for container management because that's what K8s recommends.
-* We will run a Postgres database for that part of the system because it rocks!
-* For deployment, we will check out [KubeOne](https://github.com/kubermatic/kubeone)
+Check out [demo-gitops](https://github.com/koor-tech/demo-gitops) for the latest configuration scripts. We should have system design docs there, too. A deployment diagram for each configuration would be good. What nodes are runnning? What is deployed on each?
 
-Let's keep notes about what we try. Sort of an inventor's journal.
+Let's have instructions for setting up Koor products. For instance,
