summary
Compare the Market upgrades Linkerd from 2.14.10 to 2.16.0 in one step using Flux while keeping secrets out of Git. They run 13 experiments on ephemeral clusters, suspend the Linkerd Helm release, set prune=false, split CRDs and control plane charts, and inject a runtime license secret required by Buoyant Enterprise. Surprises include chart name changes, Helm template refactors, mismatches on Artifact Hub, and using the Flux image reflector to automate non-prod rollouts.
