From Spreadsheets to "Everything as Code" — Joel Studler and Jéremy Weber
summary
Swisscom replaces scattered spreadsheets with a GitOps pipeline that stores LLD as code (Ansible inventory of IPs), pulls vendor artifacts into JFrog, and uses Flux + Helm, Jenkins + Ansible for legacy steps, Vault + External Secrets, and Testkube for tests. A cert-manager plugin integrates with Swisscom PKI and runs certificate rotation. A Netconf operator is planned to replace SSH/XML pushes. During the demo a PCG CNF redeploy finishes in minutes and the device regains 5G connectivity, proving end-to-end automation works.
