Episode notes
Git As The Single Source Of Desired State
- GitOps means everything declarative is stored in Git as the single source of desired state.
- Automated controllers converge cluster actual state to that desired state continuously.
Prefer Declarative Definitions
- Use declarative formats (YAML, JSON, HCL) rather than imperative scripts whenever possible.
- Declarative definitions make it easier for machines to compute differences and converge state.
Immutable Infrastructure Enables Previews
- Immutable infrastructure simplifies reproducibility and enables ephemeral environments like per-PR previews.
- Treat images and infra as immutable artifacts and recreate rather than patch them.
