SOPS

Name: SOPS
Availability: InStock

A standalone path through SOPS (Secrets OPerationS), the tool for encrypting secrets so they can live safely in Git. Beginner covers the problem, installing SOPS, encrypting/decrypting files, and how partial (value-only) encryption works. Intermediate builds real usage: key backends (age vs cloud KMS), .sops.yaml creation rules, key rotation and access, and formats. Advanced goes deep: SOPS in GitOps (Flux/Argo), CI/CD decryption, the Vault provider and dynamic secrets, and the secrets-management landscape. Real files and CLI output throughout; each level ends with a self-test feeding a rotating final exam.
