Ingress-NGINX is retired and about half of all clusters still run it. This is the step-by-step playbook for moving production traffic to Kubernetes Gateway API: a verified annotation-by-annotation map (including every no-equivalent case and its workaround), a decision matrix for nine implementations, inventory scripts, zero-downtime cutover and rollback runbooks, and twelve before/after manifests validated against the real CRD schemas.

Den här boken lär oss Podman genom att faktiskt använda det, laboration för laboration, från vårt allra första podman run till en komplett, rootless produktionsmiljö som startar sig själv efter en omstart. Vi bygger egna images, kopplar ihop containrar över nätverk vi själva skapar, sätter upp persistent lagring för riktiga databaser och lär oss felsöka system som faktiskt gått sönder, med flit.

Learn to write nginx modules in Rust by building a statistics module that counts requests across workers in shared memory and exposes them as Prometheus metrics.
