+# PR #2799: Workflow Design Impact Analysis
+
+## Affected Workflows
+- **Local Development Workflow**: The PR updates Dockerfiles for multiple services (cartservice, currencyservice, emailservice, loadgenerator, paymentservice, recommendationservice, shoppingassistantservice), which are explicitly listed in the workflow's relevant_files as "src/*/Dockerfile". These changes affect the Skaffold build artifacts used in local image building and hot reloading.
+- **GKE Deployment Workflow**: Updates to Dockerfiles impact the Skaffold build and push steps during `skaffold run`, as documented in the workflow's relevant_files including skaffold.yaml and src/*/Dockerfile implicitly through build process.
+- **Helm Chart Deployment**: Indirect impact; the design doc notes reliance on src/*/Dockerfile for building images that Helm deploys via templates referencing those images.
+- **Cloud Build CI/CD Pipeline**: cloudbuild.yaml invokes skaffold run, which builds from the updated Dockerfiles.
+- **Release Process**: The make-docker-images.sh script performs gcloud builds submit in each src/ directory, directly using the updated Dockerfiles to build and push tagged images.
+- **Adding New Microservice**: Changes to existing Dockerfiles update the dependency versions that serve as examples and templates in the adding-new-microservice.md guide and integrations with skaffold/helm/kustomize.
+
+## Local Development Workflow Analysis
+### Summary of design changes
+This PR performs routine dependency updates to Docker base images across several microservices' Dockerfiles. Specific changes include:
+- **cartservice/src/Dockerfile.debug**: Updated .NET aspnet and sdk image digests.
+- **currencyservice/Dockerfile**: Updated Node.js alpine builder image digest.
+- **emailservice/Dockerfile**: Updated Python from 3.12.8-slim to 3.14.0-slim.
+- **loadgenerator/Dockerfile**: Updated Python alpine image.
+- **paymentservice/Dockerfile**: Updated Node.js image digest.
+- **recommendationservice/Dockerfile**: Updated Python slim image.
+- **shoppingassistantservice/Dockerfile**: Updated Python alpine image.
+
+These updates modify the "Dockerfiles" component. The workflow sequence remains unchanged; builds now use newer bases for potential security/performance benefits. No new/removed steps. Implications: Test for compatibility.
+
+The Initial Deployment diagram updated to highlight change (yellow node for updated build step):
+
+```mermaid
+flowchart TD
+    Start((skaffold dev)) --> Load[Skaffold loads skaffold.yaml artifacts and manifests]
+    Load --> Build[Loop: docker build from src/<service>/Dockerfile for each artifact]
+    Build --> Updated[Docker Build: Uses updated base images in Dockerfiles yellow change]
+    Updated --> Kustomize[kustomize build kubernetes-manifests/ | kubectl apply]
+    Kustomize --> Pods[K8s creates Deployments, Services, Pods pulling local images]
+    Pods --> PF[kubectl port-forward frontend 8080:8080]
+    PF --> Access[Access app at localhost:8080]
+    style Updated fill:#ffeb3b,stroke:#333,stroke-width:2px
+```
+
+Similar for Hot Reload.
+
+No updates to design doc needed.
+
+## GKE Deployment Workflow Analysis
+### Summary of design changes
+Similar updates affect Skaffold's build/push in GKE workflow. Newer images pushed to registry. Benefits for cloud deploys.
+
+Updated Direct Deployment diagram (highlighted changed build step with yellow):
+
+```mermaid
+flowchart TD
+    Start((skaffold run --default-repo=registry)) --> Parse[Skaffold parses config app/loadgenerator]
+    Parse --> BuildLoop[Loop for service artifacts: Build image from Dockerfile]
+    BuildLoop --> UpdatedBuild[Builder: Updated base images/digests in Dockerfiles yellow change]

+    Push --> TagUpdate[Update image tags in manifests]

+    GetIP --> Access[External IP access]
+    style UpdatedBuild fill:#ffeb3b,stroke:#333,stroke-width:2px
+```
+
+No doc updates.
+
+## Helm Chart Deployment Analysis
+### Summary of design changes
+Indirect: Updated Dockerfiles affect images pulled during pod scheduling in Helm deployments. No change to Helm logic.
+
+Updated Deployment Flow diagram (highlighted changed image pull with yellow):
+
+```mermaid
+flowchart TD
+    Start((helm upgrade --install)) --> Load[Load chart and values]
+    Load --> Render[Merge values, render templates Deployments/Services etc.]
+    Render --> Apply[Apply YAMLs to K8s API]

+    style UpdatedPull fill:#ffeb3b,stroke:#333,stroke-width:2px
+```
+
+No doc updates.
+
+## Cloud Build CI/CD Pipeline Analysis
+### Summary of design changes
+The pipeline uses cloudbuild.yaml to run skaffold run, so Dockerfile updates affect remote builds in Cloud Build. Similar benefits. No design doc to update diagram.
+
+## Release Process Analysis
+### Summary of design changes
+make-docker-images.sh and related scripts build images per service using Dockerfiles; updates ensure release images use latest bases. No diagram.
+
+## Adding New Microservice Analysis
+### Summary of design changes
+When adding new service, developers reference existing Dockerfiles as templates; updates modernize these examples. Affects integration with build tools.
