 ## Software stack
 
-The cluster itself is based on [Talos Linux](https://www.talos.dev/) (which is also a Kubernetes distribution) and uses [Cilium](https://cilium.io/) as CNI, IPAM, kube-proxy replacement, Load Balancer, and BGP control plane. Persistent volumes are managed by [OpenEBS LVM LocalPV](https://openebs.io/docs/user-guides/local-storage-user-guide/local-pv-lvm/lvm-overview). Applications are deployed using GitOps (this repo) and reconciled on cluster using [Flux](https://fluxcd.io/). Git repository is hosted on [Gitea](https://gitea.io/) running on a cluster itself. Secets are kept in [OpenBao](https://openbao.org/) (HashiCorp Vault fork) running on a cluster and synced to cluster objects using [Vault Secrets Operator](https://github.com/hashicorp/vault-secrets-operator). Deployments are kept up to date using self hosted [Renovate](https://www.mend.io/renovate/) bot updating manifests in the Git repository. Incoming HTTP traffic is routed to cluster using [Nginx Ingress Controller](https://kubernetes.github.io/ingress-nginx/) and certificates are issued by [cert-manager](https://cert-manager.io/) with [Let's Encrypt](https://letsencrypt.org/) ACME issuer with [cert-manager-webhook-ovh](https://github.com/aureq/cert-manager-webhook-ovh) resolving DNS-01 challanges. Cluster also runs [CloudNativePG](https://cloudnative-pg.io/) operator for managing PostgreSQL databases. Router is running [Mikrotik RouterOS](https://help.mikrotik.com/docs/spaces/ROS/pages/328059/RouterOS) and its configuration is managed via [Ansible](https://docs.ansible.com/) playbook in this repo. High level core cluster software architecture is shown on the diagram below.

 > Talos Linux is an immutable Linux distribution purpose-built for running Kubernetes. The OS is distributed as an OCI (Docker) image and does not contain any package manager, shell, SSH, or any other tools for managing the system. Instead, all operations are performed using API, which can be accessed using `talosctl` CLI tool.
