Highly available Kubernetes setup on Oracle Cloud Always Free Tier.
- Remove all CPU limits
- Migrate all helm repo app-template to oci
- Fix alerting rules to Discord
- Monitor authentik uptime either VMServiceScrape or VMProbe
Only Network Load Balancers have a public IP, all Talos nodes have only Private IPs and can be ONLY accessed via OCI Bastion.
Updates are managed by Renovate Bot. I am using my own GitHub App to create and merge PRs.
