Empowering SRE with GitOps
summary
Shows a concrete GitOps pipeline using GitLab CI with Kaniko to build images, Artifactory as registry and Flux as the operator. The demo bootstraps a cluster, uses Flux image automation controller to scan 38 tags and bump a release from 43 to 44, rewrites the Git manifests, and successfully rolls pods; a manual replica change is auto-reverted. Includes recommendations on secrets, branch protection, semantic version policies and a hands-on K3s + Flux workshop.
