☸️ Deploy the Kubernetes clusters

I'm using a self-hosted instance of Sidero Omni to manage and deploy my Kubernetes clusters.

You'll need the following:

• A static public IP address with a router able to forward ports
• A domain name with a DNS provider usable with ExternalDNS
• Any secret provider supported by External Secrets Operator. This repository uses GitLab as it's secrets provider
• An API token of the DNS provider that will allow challenges to create certificates. This repository uses a Cloudflare token with the permissions: Zone - DNS - Edit, Zone - Zone - Read & Include - All Zones
• Another API token of the same provider to manage DNS records. Using Cloudflare, the token should have the same permissions as above
• A GitHub PAT to be used by FluxCD, with Read-Write permissions for Admnistration & Contents

🔑 Secrets

Here is the following list of secrets you need to add in your external secrets provider of choice before starting the cluster:

Name	Description
dns_provider_challenge_token	API token of your DNS management provider of your domain, used to generate the x.509 certificates
dns_provider_management_token	API token of your DNS management provider of your domain, used to manage your DNS records
authentik_key	Random string of atleast 50 caracters long (ex: openssl rand -base64 50)
renovate_token	Git token for the Renovate account
