A step-by-step guide to running Claude Code as a VSCode plugin inside OpenShift Dev Spaces, integrated with a locally deployed AI model (RedHatAI/gpt-oss-20b) served via vLLM. Covers enabling GPU support on OpenShift with NVIDIA operators, deploying vLLM with the Anthropic Messages API, configuring Eclipse Che (Dev Spaces) with the Claude Code extension, and overriding Anthropic API endpoints to point to the internal cluster service — enabling a fully self-contained AI-assisted development environment on OpenShift.
