Personal Infra Update

April 26, 2023

Previously my website hosted in multiple free services available in the Internet. For my application/development experiment finally i moved to Kubernetes cluster hosted in Vultr, since at the end of 2022.

Comparing the old and the new version.

Updated deployment diagram:

The diagram created using `diagrams` package, diagram as code https://diagrams.mingrammer.com/

Gitops, The configuration

The k8s cluster managed by Flux in Github private repository github.com/sakti/personal-infra with alert from Flux defined as commit status.

The components

• ingress-nginx for Ingress
• cert-manager for manage TLS cerficate from Let's Encrypt
• PGO, for PostgreSQL Operator; self managed PostgreSQL database running in k8s
• Minio, for s3 compatible storage

The apps

• web; this web app (pages, blogs, etc) build using Django + Wagtail, using async as much as possible in Django and using experimental Granian a Rust HTTP server for Python app
• katze; https://katze.saktidwicahyono.name, cat ascii web app from this series from fasterthanlime "Building a Rust service with Nix". This app also used for load testing target to test cache "request coalescing" from the original cat image source.
• future app namespace, the next application/system experiment

The monitor

• k8s cluster monitored by Grafana
• web error tracking monitored using Sentry
• katze tracing managed by Honeycomb

Conclusion

With this migration, I am able to trade recurring monthly costs for much more flexibility in deploying my experimental apps.
