yaml files for my homelab k8s instance.

Helmfile Tips

When setting up a new cluster:

1. cd bootstrap
2. helmfile diff - review changes
3. helmfile apply

To remove helmfile controlled things:

1. Add installed: false to helmfile.yaml
2. Review helmfile diff
3. Run helmfile apply
4. Remove the entry that installed: false was added to

Applying Files

Any yaml files with sensitive information contain 1Password references. To apply them to the cluster:

cat cloudflare/tunnel-token.yaml.tpl | op inject | kubectl apply -f -

Exposing Services

Services are exposed via a cloudflared tunnel. Once the service is stood up, some manual configuration in cloudflare is necessary.

1. Visit Cloudflare and sign in
2. Visit Sign in > Zero Trust > Networks > Tunnels > Edit
3. Add the url to the service: <service-name>.<namespace-name>.svc.cluster.local:<service-port>

Other Tips

• Grafana Dashboards - ids can be grabbed and added to ./monitoring/datasources-and-dashboards.yaml
  • If the dashboard doesn't load, sometimes a datasources var has to be specified
• Prometheus Helm Charts - additional services can be scraped if added
  • Think Redis, Erlang, etc.
