# Kubernetes cluster
Kubernetes hosts run on [PVE Cluster](https://wiki.k-space.ee/en/hosting/proxmox). Hosts are listed in Ansible [inventory](ansible/inventory.yml).
## `kubectl`
- Authorization [ACLs](cluster-role-bindings.yml)
- [Troubleshooting `no such host`](#systemd-resolved-issues)
Authenticate to auth.k-space.ee:
```bash
kubectl krew install oidc-login

## Cluster formation
Created Ubuntu 22.04 VM-s on Proxmox with local storage.
Added some ARM64 workers by using Ubuntu 22.04 server on Raspberry Pi.
After machines have booted up and you can reach them via SSH:
```
# Disable Ubuntu caching DNS resolver
systemctl disable systemd-resolved.service
systemctl stop systemd-resolved
rm -fv /etc/resolv.conf
cat > /etc/resolv.conf << EOF
nameserver 1.1.1.1
nameserver 8.8.8.8
EOF
# Disable multipathd as Longhorn handles that itself
systemctl mask multipathd snapd
systemctl disable --now multipathd snapd bluetooth ModemManager hciuart wpa_supplicant packagekit
# Permit root login
sed -i -e 's/PermitRootLogin no/PermitRootLogin without-password/' /etc/ssh/sshd_config
systemctl reload ssh
cat ~ubuntu/.ssh/authorized_keys > /root/.ssh/authorized_keys
userdel -f ubuntu
apt-get install -yqq linux-image-generic
apt-get remove -yq cloud-init linux-image-*-kvm
```
On master:
```
kubeadm init --token-ttl=120m --pod-network-cidr=10.244.0.0/16 --control-plane-endpoint "master.kube.k-space.ee:6443" --upload-certs --apiserver-cert-extra-sans master.kube.k-space.ee --node-name master1.kube.k-space.ee
```
For the `kubeadm join` command specify FQDN via `--node-name $(hostname -f)`.
Set AZ labels:
```
for j in $(seq 1 9); do
for t in master mon worker storage; do
kubectl label nodes ${t}${j}.kube.k-space.ee topology.kubernetes.io/zone=node${j}
done
done
```
After forming the cluster add taints:
```bash
for j in $(seq 1 9); do
kubectl label nodes worker${j}.kube.k-space.ee node-role.kubernetes.io/worker=''
done
for j in $(seq 1 4); do
kubectl taint nodes mon${j}.kube.k-space.ee dedicated=monitoring:NoSchedule
kubectl label nodes mon${j}.kube.k-space.ee dedicated=monitoring
done
for j in $(seq 1 4); do
kubectl taint nodes storage${j}.kube.k-space.ee dedicated=storage:NoSchedule
kubectl label nodes storage${j}.kube.k-space.ee dedicated=storage
done
```
For `arm64` nodes add suitable taint to prevent scheduling non-multiarch images on them:
```bash
kubectl taint nodes worker9.kube.k-space.ee arch=arm64:NoSchedule
```
For door controllers:
```
for j in ground front back; do
kubectl taint nodes door-${j}.kube.k-space.ee dedicated=door:NoSchedule
kubectl label nodes door-${j}.kube.k-space.ee dedicated=door
kubectl taint nodes door-${j}.kube.k-space.ee arch=arm64:NoSchedule
done
```
To reduce wear on storage:
```
echo StandardOutput=null >> /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
systemctl daemon-reload
systemctl restart kubelet
```

# Kubernetes cluster manifests
# k-space.ee infrastructure
Kubernetes manifests, Ansible [playbooks](ansible/README.md), and documentation for K-SPACE services.
## Introduction
- Repo is deployed with [ArgoCD](https://argocd.k-space.ee). For `kubectl` access, see [CLUSTER.md](CLUSTER.md#kubectl).
- Debugging Kubernetes [on Wiki](https://wiki.k-space.ee/en/hosting/debugging-kubernetes)
- Need help? → [`#kube`](https://k-space-ee.slack.com/archives/C02EYV1NTM2)
This is the Kubernetes manifests of services running on k-space.ee domains.
The applications are listed on https://auth2.k-space.ee for authenticated users.
Jump to docs: [inventory-app](hackerspace/README.md) / [cameras](camtiler/README.md) / [doors](https://wiki.k-space.ee/en/hosting/doors) / [list of apps](https://auth.k-space.ee) // [all infra](ansible/inventory.yml) / [network](https://wiki.k-space.ee/en/hosting/network/sensitive) / [retro](https://wiki.k-space.ee/en/hosting/retro) / [non-infra](https://wiki.k-space.ee)
## Supporting services
- Build [Git](https://git.k-space.ee) repositories with [Woodpecker](https://woodpecker.k-space.ee).
- Passmower: Authz with `kind: OIDCMiddlewareClient` (or `kind: OIDCClient`[^authz]).
- Traefik[^nonginx]: Expose services with `kind: Service` + `kind: Ingress` (TLS and DNS **included**).
## Cluster access
### Additional
- bind: Manage _additional_ DNS records with `kind: DNSEndpoint`.
- [Prometheus](https://wiki.k-space.ee/en/hosting/monitoring): Collect metrics with `kind: PodMonitor` (alerts with `kind: PrometheusRule`).
- [Slack bots](SLACK.md) and Kubernetes [CLUSTER.md](CLUSTER.md) itself.
General discussion is happening in the `#kube` Slack channel.
[^nonginx]: No nginx annotations! Use `kind: Ingress` instead. `IngressRoute` is not used as it doesn't support [`external-dns`](bind/README.md) out of the box.
[^authz]: Applications should prefer `Remote-User` (`kind: OIDCGWMiddlewareClient`), which gates app exposure to the public internet. Where not applicable or possible, use OpenID Connect (`kind: OIDCClient`) for authentication.
<details><summary>Bootstrapping access</summary>
For bootstrap access obtain `/etc/kubernetes/admin.conf` from one of the master
nodes and place it under `~/.kube/config` on your machine.
### Databases / -stores:
- KeyDB: `kind: KeydbClaim` (replaces Redis[^redisdead])
- Dragonfly: `kind: Dragonfly` (replaces Redis[^redisdead])
- Longhorn: `storageClassName: longhorn` (filesystem storage)
- Mongo[^mongoproblems]: `kind: MongoDBCommunity` (NAS* `inventory-mongodb`)
- Minio S3: `kind: MinioBucketClaim` with `class: dedicated` (NAS*: `class: external`)
- MariaDB*: search for `mysql`, `mariadb`[^mariadb] (replaces MySQL)
- Postgres*: hardcoded to [harbor/application.yml](harbor/application.yml)
Once Passmower is working, OIDC access for others can be enabled with
running following on Kubernetes masters:
\* External, hosted directly on [nas.k-space.ee](https://wiki.k-space.ee/en/hosting/storage)

The following can be used to talk to the Kubernetes cluster using OIDC credentials:
[^redisdead]: Redis has been replaced as redis-operatori couldn't handle itself: didn't reconcile after reboots, master URI was empty, and clients complained about missing masters. ArgoCD still hosts its own Redis.

External dependencies running as classic virtual machines:
- Bind as DNS server
## Adding applications
Deploy applications via [ArgoCD](https://argocd.k-space.ee)
We use Treafik with Passmower for Ingress.
Applications where possible and where applicable should use `Remote-User`
authentication. This prevents application exposure on public Internet.
Otherwise use OpenID Connect for authentication,
see Argo itself as an example how that is done.
See `camtiler/ingress.yml` for commented Ingress example.
Note that we do not use IngressRoute objects because they don't
support `external-dns` out of the box.
Do NOT add nginx annotations, we use Traefik.
Do NOT manually add DNS records, they are added by `external-dns`.
Do NOT manually create Certificate objects,
these should be handled by `tls:` section in Ingress.
## Cluster formation
Created Ubuntu 22.04 VM-s on Proxmox with local storage.
Added some ARM64 workers by using Ubuntu 22.04 server on Raspberry Pi.
After machines have booted up and you can reach them via SSH:
```
# Disable Ubuntu caching DNS resolver
systemctl disable systemd-resolved.service
systemctl stop systemd-resolved
rm -fv /etc/resolv.conf
cat > /etc/resolv.conf << EOF
nameserver 1.1.1.1
nameserver 8.8.8.8

# Disable multipathd as Longhorn handles that itself

# Permit root login
sed -i -e 's/PermitRootLogin no/PermitRootLogin without-password/' /etc/ssh/sshd_config
systemctl reload ssh
cat ~ubuntu/.ssh/authorized_keys > /root/.ssh/authorized_keys
userdel -f ubuntu
apt-get install -yqq linux-image-generic
apt-get remove -yq cloud-init linux-image-*-kvm
```
On master:
```
kubeadm init --token-ttl=120m --pod-network-cidr=10.244.0.0/16 --control-plane-endpoint "master.kube.k-space.ee:6443" --upload-certs --apiserver-cert-extra-sans master.kube.k-space.ee --node-name master1.kube.k-space.ee
```
For the `kubeadm join` command specify FQDN via `--node-name $(hostname -f)`.
Set AZ labels:
```
for j in $(seq 1 9); do
for t in master mon worker storage; do
kubectl label nodes ${t}${j}.kube.k-space.ee topology.kubernetes.io/zone=node${j}
done
done
```
After forming the cluster add taints:
```bash
for j in $(seq 1 9); do
kubectl label nodes worker${j}.kube.k-space.ee node-role.kubernetes.io/worker=''
done
for j in $(seq 1 4); do
kubectl taint nodes mon${j}.kube.k-space.ee dedicated=monitoring:NoSchedule
kubectl label nodes mon${j}.kube.k-space.ee dedicated=monitoring
done
for j in $(seq 1 4); do
kubectl taint nodes storage${j}.kube.k-space.ee dedicated=storage:NoSchedule
kubectl label nodes storage${j}.kube.k-space.ee dedicated=storage
done
```
For `arm64` nodes add suitable taint to prevent scheduling non-multiarch images on them:
```bash
kubectl taint nodes worker9.kube.k-space.ee arch=arm64:NoSchedule
```
For door controllers:
```
for j in ground front back; do
kubectl taint nodes door-${j}.kube.k-space.ee dedicated=door:NoSchedule
kubectl label nodes door-${j}.kube.k-space.ee dedicated=door
kubectl taint nodes door-${j}.kube.k-space.ee arch=arm64:NoSchedule
done
```
To reduce wear on storage:
```
echo StandardOutput=null >> /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
systemctl daemon-reload
systemctl restart kubelet
```
