Program narrative
Progressive delivery patterns with Argo CD, including ApplicationSet generators, cluster selectors, and progressive syncs that do not surprise app owners. You will rehearse failure modes where Git and cluster state disagree.
Included focus areas
- • Generator patterns that avoid explosive cardinality
- • Sync waves that respect startup ordering
- • Secrets integration without copying kubeconfigs
- • Diff customization for noisy controllers
- • Rollback rehearsals with recorded outcomes
- • RBAC that matches team boundaries
- • Promotion notes embedded in commit messages
Outcomes you can show
- Stand up an ApplicationSet spanning three lab clusters
- Author a rollback note template adopted by peers
- Demonstrate a drift detection drill with timestamps
Mentor of record
Daniel Okoro
Cloud lab engineer who keeps clusters boring for product squads.
Participant notes
Sync wave lab finally stopped our race conditions during migrations. Still documenting exceptions.
Straight answers
You should already be comfortable deploying workloads; this is GitOps-layer focus.
