Vulnerability scanning as a deploy gate
Scan with Trivy or Clair, fail the build on high or critical severity above threshold, and enforce again at admission with signing and registry policies.
Manifest lists and multi-arch images
A manifest list maps platform descriptors to per-arch image manifests, the client picks by os and architecture, and pulls only that variant.
Three techniques to shrink a Docker image
Multi-stage builds to drop build tooling, smaller base images like slim or distroless, and fewer or cleaner layers plus dockerignore.
Debugging ImagePullBackOff on a private registry
ImagePullSecrets reference a dockerconfigjson Secret on the pod or service account, kubelet uses it to authenticate, and you inspect events to isolate auth versus name versus network errors.
Why :latest is a production anti-pattern
Latest is mutable so pods run different code, rollbacks and pull policy break, and you should use immutable version tags or digests.
Tag and push an image to a private registry
Authenticate with docker login, retag the image to include the registry host and repo path, then docker push that full reference.
Docker Compose profiles for optional services
Profiles tag services so they stay off by default, activate via --profile or COMPOSE_PROFILES, and unprofiled services always run.
Optimizing Dockerfile layer caching
Order instructions least-to-most volatile, copy dependency manifests and install before copying source, and understand any changed layer busts all later layers.
Structuring Compose files across environments
A base compose.yaml plus override files, the default override auto-merge, and explicit -f flags or extends per environment.
Structuring color tokens for a new app
Primitive palette, semantic role tokens, optional component tokens, theming benefit.
A simple automatable metric for dev-time savings
Component coverage or cycle time, gathered automatically, compared across adoption levels.
Framework-agnostic components across React, Vue, Angular
Web components for one core, framework wrappers for ergonomics, codegen as an alternative, with their costs.
Documentation for a new Card component
Usage guidance and do/don't, variants, accessibility, code examples, composition.
Design tokens for multi-brand button theming
Tokens as named design decisions, primitive-versus-semantic layers, per-brand themes mapping semantic to primitive.
End-to-end process for a Modal props API break
Justify and design the change, additive rollout with deprecation, major release plus codemod, comms and adoption tracking.
Measuring designer efficiency from Figma data
Library component usage and detach rates from Figma, time-to-mockup, override frequency via the API.
Linking form-component adoption to fewer a11y bugs
Define both variables, segment by adoption level, control confounders, watch correlation-versus-causation.
Gradual design system adoption in legacy code
Coexistence strategy, codemods for mechanical swaps, lint rules to block regressions, prioritize high-traffic surfaces.
Measuring design system adoption and health
Component coverage and version spread from code scans, usage analytics, issue and satisfaction signals.
Technical and comms plan for a Button break
Additive-first then deprecate, major semver, codemod and guide, multi-channel early comms with adoption tracking.
