✅ What Was Fixed / Updated

  1. Database Deployment (Kubernetes Storage Fix)
  • Resolved MongoDB deployment issues caused by outdated in-tree AWS EBS storage drivers.
  • Added a new gp2 StorageClass YAML using the AWS EBS CSI driver, which is required for newer Kubernetes versions.
  • Updated storage-related configuration and documented the required commands in the README.
  1. Frontend Configuration Updates
  • Removed hardcoded host links from frontend configuration.
  • Updated frontend to communicate with the backend using the Kubernetes service name (backend-service).
  • Added port 80 configuration in ingress.yaml to properly expose the frontend.
  • YAML File Improvements
  • Updated YAML files for frontend, backend, and database deployments.
  • Added a new ingress.yaml with the necessary configuration changes.
  1. Environment & Project Adjustments
  • Updated WORKDIR, namespace, and AWS region values where required.
  • Made configuration changes flexible so users can pull and adjust only what is needed for their environment.

🚀 Result

  • The application is now successfully deployed and accessible using the provided Kubernetes host link.
  • All components (frontend, backend, database) are running as expected.
  • The full deployment was completed successfully within 6 hours.

🙌 Thank you
Thanks for the great tutorial — it worked well, and these updates help ensure compatibility with newer Kubernetes and AWS EKS setups.

📝 Walkthrough

Walkthrough

Updates Dockerfiles (working dir formatting), switches container images to public ECR, adds AWS EBS CSI StorageClass and PVC adjustments, introduces a comprehensive IAM policy, replaces frontend Service with a renamed ClusterIP, alters Ingress to path-based routing, and appends StorageClass installation docs to README.

Changes

Cohort / File(s) Summary
Docker Configuration
Application-Code/backend/Dockerfile, Application-Code/frontend/Dockerfile
Changed WORKDIR from /usr/src/app to /app; standardized CMD JSON array formatting and minor Dockerfile whitespace/format tweaks.
Container Registry & Env
Kubernetes-Manifests-file/Backend/deployment.yaml, Kubernetes-Manifests-file/Frontend/deployment.yaml
Switched backend/frontend images to public ECR (public.ecr.aws/...); frontend env REACT_APP_BACKEND_URL changed from full URL to "/api/tasks".
Kubernetes Storage
Kubernetes-Manifests-file/Database/gp2-csi.yaml, Kubernetes-Manifests-file/Database/pvc.yaml
Added gp2-csi StorageClass (ebs.csi.aws.com) with WaitForFirstConsumer and volume expansion; PVC updated to reference gp2-csi and formatting/order adjusted.
Frontend Service Refactor
Kubernetes-Manifests-file/Frontend/frontend-service.yaml, Kubernetes-Manifests-file/Frontend/service.yaml
Removed old service.yaml; added frontend-service.yaml ClusterIP frontend-service exposing port 80 → targetPort 3000 (service renamed).
Ingress Routing
Kubernetes-Manifests-file/ingress1.yaml
Removed host constraint; converted to path-based rules for /api and /; API backend port explicitly set to 3500; frontend backend now targets frontend-service port 80.
IAM Policy
Kubernetes-Manifests-file/iam_policy.json
New, large JSON IAM policy granting granular permissions across EC2, ELB, ACM, Cognito, WAF, Shield, and related resources with tag/resource conditions.
Documentation
README.md
Added "Fixed storage drivers for latest K8s" section with step-by-step AWS EBS CSI Driver installation and StorageClass/PVC instructions.

Poem

🐰 I hopped from private crates to public skies,
I dug new roots where gp2 lies,
I nudged the ingress path just so,
Renamed a service, let traffic flow,
A tiny hop — infra ready to grow! 🥕

24-57: Add securityContext with privilege escalation and root execution restrictions.

The pod lacks a securityContext, leaving it vulnerable to privilege escalation and root execution. Add the hardening measures below:

       containers:
       - name: api
         image: public.ecr.aws/y4y0r8u9/three-tier-backend:latest
         imagePullPolicy: Always

Consider also testing readOnlyRootFilesystem: true if the application doesn't write to the filesystem.

24-34: Add container securityContext for security hardening.

The frontend deployment lacks essential security constraints. Add allowPrivilegeEscalation: false, runAsNonRoot: true, and drop all capabilities to align with Kubernetes Pod Security Standards.

In `@Application-Code/frontend/Dockerfile`:
- Around line 1-11: Update the Dockerfile's base image line that currently reads
"FROM node:14" to use a supported LTS tag (e.g., "FROM node:lts") so the
container runs on a maintained Node.js release; make this change in the
Dockerfile (look for the FROM node:14 line) and after validating compatibility
locally pin to a specific LTS version tag (for repeatable builds) before
merging.

In `@README.md`:
- Around line 187-230: Update the README references to use the actual repository
file paths/names: replace occurrences of "gp2-csi.yaml" with
"Kubernetes-Manifests-file/Database/gp2-csi.yaml" and "mongo-pvc.yaml" with
"Kubernetes-Manifests-file/Database/pvc.yaml" (or vice-versa if you prefer
renaming files in the repo); ensure commands shown (kubectl apply/delete) use
those repo-relative paths so readers can copy-paste them directly and avoid
confusion with the manifest filenames used in the repo.
- Around line 256-259: The Markdown file uses a horizontal rule (`---`)
immediately after a section which causes the previous line to be parsed as a
setext heading; update the README by adding a blank line before the `---` or
replacing the `---` with an explicit separator (or remove it) so the "## No need
hosts in Values" heading and the horizontal rule do not conflict—locate the
heading text "No need hosts in Values" and ensure a blank line precedes the
`---` to fix the MD003 warning.
- Around line 159-170: Replace the hard-coded region values in the storage

update the two occurrences of "--region us-east-1" in the "eksctl utils

aws-ebs-csi-driver" block to use "--region <your-region>" so they align with the

🧹 Nitpick comments (2)
Kubernetes-Manifests-file/Backend/deployment.yaml (1)

24-30: Pin the image to an immutable tag/digest (and drop unused pull secret if public).

Using :latest with imagePullPolicy: Always makes rollouts non‑deterministic. If the image is public, you can remove the pull secret to avoid missing‑secret warnings.

♻️ Suggested change
-      imagePullSecrets:

Kubernetes-Manifests-file/iam_policy.json (1)

1-251: Verify this policy is scoped to the controller service account via IRSA, not attached to node or user roles.

This is the standard AWS Load Balancer Controller IAM policy. The tag-based conditions (elbv2.k8s.aws/cluster) are correctly in place for cluster-level scoping. However, ensure it is bound via IRSA (IAM Roles for Service Accounts) to the AWS Load Balancer Controller's Kubernetes ServiceAccount—not attached to EC2 node roles or human users. The policy grants broad EC2 and ELB permissions; IRSA containment prevents unintended access leakage.

  • Create the IRSA role with a tightly-scoped trust policy tied to your cluster's OIDC provider, namespace, and service account name.
  • Document the intended use (e.g., in a Helm values file or README) so future operators understand this is controller-only.
  • Reference: AWS Load Balancer Controller installation guide.

Align region placeholders across the README.

The new storage driver commands use us-east-1 (lines 160, 170) while earlier setup instructions consistently use us-west-2 (lines 96, 97, 112, 113, 129). Replace both instances with <your-region> to keep the documentation flexible and consistent with the <your-cluster-name> placeholder pattern used throughout.

Use repo paths/names for the StorageClass and PVC files.

The section references gp2-csi.yaml and mongo-pvc.yaml, but the repo file names appear to be Kubernetes-Manifests-file/Database/gp2-csi.yaml and Kubernetes-Manifests-file/Database/pvc.yaml. Aligning the names reduces copy‑paste errors.

🧹 Nitpick comments (1)

187-225: Consider referencing files instead of duplicating YAML content.

The inline YAML examples (StorageClass at lines 189-198, PVC at lines 214-225) duplicate content that should exist in Kubernetes-Manifests-file/Database/gp2-csi.yaml and pvc.yaml. While helpful for readers, this creates a risk that documentation and actual files drift apart over time.

Alternative approach: Replace inline YAML with a brief description and direct readers to view the actual file, e.g.:

Create or verify `Kubernetes-Manifests-file/Database/gp2-csi.yaml` contains a StorageClass with:
- provisioner: `ebs.csi.aws.com`
- type: `gp2`
- volumeBindingMode: `WaitForFirstConsumer`

See the file for complete configuration.

This keeps docs concise while ensuring single source of truth for YAML content.

Reconcile namespace mismatch between documentation and manifests.

Step 8 (line 103) instructs users to create a workshop namespace, but all Kubernetes manifest files reference namespace: three-tier. When users run kubectl apply -f ., resource creation will fail because the manifests target a non-existent namespace. Either update line 103 to kubectl create namespace three-tier, or update all manifest files to use workshop.

In `@README.md` around lines 209 - 247, Documentation and manifests disagree on
the Kubernetes namespace: README step 8 creates a workshop namespace but all
manifests (e.g., mongo-pvc.yaml) use namespace: three-tier, causing kubectl
apply -f . to fail; fix by making them consistent—either change the README step
that runs kubectl create namespace workshop to kubectl create namespace
three-tier, or update every manifest containing namespace: three-tier to
namespace: workshop (ensure the mongo-pvc.yaml and other manifest files are
updated accordingly), and then verify the README commands that reference the
namespace (kubectl delete pvc mongo-volume-claim -n three-tier, kubectl delete
pod -n three-tier -l app=mongodb, kubectl get pods -n three-tier, etc.) are
updated to the chosen namespace.

In `@README.md` at line 256, Fix the header text "## No need doamin in Values i
added backend service" by correcting typos and grammar: change "doamin" to
"domain", capitalize "I", and add proper punctuation; for example update the
header to "## No need for domain in Values — I added a backend service" (or
similar clear phrasing) so the meaning is correct and readable.
