Notes Conrad DevOps General interview questions about the platform side of your Conrad DevOps note: Cloudflare at the edge, CI/CD, Docker and Kubernetes, A/B testing, SEO for a server-rendered shop, and your Develit architecture to compare. Plus the questions to ask them.
Pages Cloudflare at the edge What Cloudflare does in front of Conrad's storefront and why the app runs on GKE rather than Workers, with answers to the open questions in your notes — WAF, Snippets, the CF-Device-Type header, Cloudflare Access, Apigee and the 512-character limit — and edge versus origin caching. CI/CD pipeline How a change reaches Conrad's production — GitLab CI tests and lint, Kaniko builds the image, assets go to Cloud Storage behind the CDN, Terraform reads secrets and applies the Helm release, and GKE rolls out the pods — plus image tags, deploy ordering and build-once runtime configuration. Docker and Kubernetes The container and cluster basics from your Conrad notes — images and containers, a Nuxt multi-stage Dockerfile, what the image contains, .dockerignore, Compose and volumes, Deployment, Service, HPA and Istio VirtualService, probes, rolling updates and Service types. A/B testing A/B testing with a tool like Kameleoon on a site with server rendering and a page cache — assigning visitors, avoiding flicker, keeping variants out of the shared cache, and feature flags. Your Develit architecture How to present the platform you worked on at Develit — isolated Cloudflare Workers services behind an orchestrating gateway, service bindings and Workers RPC, KV for exchange rates, Durable Objects for idempotency, Workflows and Queues, micro-frontends on shared Nuxt layers — and how it contrasts with Conrad's stack. SEO and crawlers Sitemaps for a catalogue of hundreds of thousands of pages, robots.txt versus noindex, canonicals and crawl budget on a server-rendered shop, and why crawlers must get the same page as users.
