Running local AI models with Ollama has transformed private AI inference. In our earlier guide, we explored how to run Ollama with NVIDIA GPU acceleration in Docker Compose. However, as teams transition their homelabs and edge servers toward declarative Kubernetes…
Deploying microservices inside a Kubernetes cluster is only half the battle; routing inbound external traffic seamlessly and securing it with automatic SSL/TLS encryption is what transforms a local test cluster into a production-grade platform. When running K3s on bare metal…
As self-hosted infrastructure grows to encompass sensitive tools—such as private AI chat platforms like Open-WebUI, local document intelligence pipelines, or K3s Kubernetes clusters—exposing every management endpoint directly to the public internet is a dangerous anti-pattern. While reverse proxies with SSL…
Docker has become the backbone of modern infrastructure, powering everything from local homelabs to enterprise microservices. Yet, beneath its convenience lies a well-known security reality that keeps DevSecOps engineers awake at night: by default, the Docker daemon (dockerd) runs with…
