In `@k8s/backend-deployment.yaml`:
- Around line 24-25: The MONGODB_URI currently embeds plaintext credentials;
extract the username/password into a Kubernetes Secret (add keys like
mongodb-username and mongodb-password alongside the existing jwt-secret) and
update the Deployment to stop hardcoding credentials by replacing the single
MONGODB_URI env var with either (a) separate env vars MONGODB_USER and
MONGODB_PASSWORD (and MONGODB_HOST/DB) sourced from the new Secret and construct
the URI in the app, or (b) construct MONGODB_URI from secret-backed env vars via
the container's command/args or an init container; modify the env var named
MONGODB_URI in the manifest to reference secretRef env vars instead of the
literal "mongodb://mongoadmin:secret123@..." string so credentials are no longer
in plaintext.
In `@k8s/ingress.yaml`:
- Line 9: The ingress currently uses the
nginx.ingress.kubernetes.io/rewrite-target: / annotation which strips the /api
prefix (path: "/api") and breaks backend routes registered at /api/auth,
/api/messages, and /health (see backend/src/index.js); fix by either removing
the nginx.ingress.kubernetes.io/rewrite-target annotation entirely so requests
keep the /api prefix, or change the ingress path to a capture-group pattern
(e.g., path matching /api(/|$)(.*)) and set the rewrite-target to preserve /api
(e.g., rewrite to /api/$2) so the backend routes remain reachable.
In `@k8s/mongo-persistentvolume.yaml`:
- Around line 3-5: The PersistentVolume manifest has a typo in metadata.name
("monogo-pv") and includes an unnecessary metadata.namespace (PV is
cluster-scoped). Rename the PV to the correct identifier ("mongo-pv") by
updating metadata.name and remove the metadata.namespace field entirely; check
any references (e.g., PersistentVolumeClaim or StorageClass) that expect
"monogo-pv" and update them to "mongo-pv" as needed.
- Around line 6-12: The PersistentVolume spec is missing storageClassName which
prevents static PV/PVC binding; update the PV manifest by adding
storageClassName: "" under spec (near accessModes/capacity/hostPath) and ensure
the corresponding PVC also sets storageClassName: "" so the PVC can bind to this
static PV; also note that hostPath (the hostPath: path: /data entry) is only
suitable for single-node/dev clusters and may not survive node failures—consider
using a proper cluster storage class for production.
In `@k8s/mongodb-deployment.yaml`:
- Around line 24-27: Do not hardcode MongoDB credentials: create a Kubernetes
Secret (e.g., name it mongo-credentials) containing keys for
MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD (and optionally a
MONGODB_URI) and update the MongoDB Deployment to stop using literal values —
replace the env entries for MONGO_INITDB_ROOT_USERNAME and
MONGO_INITDB_ROOT_PASSWORD with valueFrom: secretKeyRef referencing the new
secret; likewise update the backend Deployment where MONGODB_URI is currently
embedded to either pull username/password from the same secret (and build the
URI from those env vars) or reference a MONGODB_URI key in the secret via
secretKeyRef so no credentials remain in plain text in the manifests.
- Around line 19-27: The container "chatapp-mongodb" lacks a volumeMount for the
declared volume "mongo-storage", so MongoDB will write to ephemeral storage; add
a volumeMount entry under the "chatapp-mongodb" container referencing name:
mongo-storage and mountPath: /data/db (ensuring it's not readOnly) so the PVC
actually backs MongoDB data, and verify the "mongo-storage" volume/PVC is
correctly declared in the pod spec.
In `@k8s/secrets.yaml`:
- Around line 1-8: The manifest k8s/secrets.yaml currently contains a hardcoded
base64 JWT secret (Secret name chatapp-secrets, key jwt-secret, namespace
chat-app); remove the secret value from the committed file and replace the
workflow with a secure injection pattern (e.g., convert to a SealedSecret,
configure External Secrets Operator to pull jwt-secret from your secrets
backend, or render the secret via Helm values at deploy time from CI/CD). Also
ensure k8s/secrets.yaml (or any file containing cleartext/base64 secrets) is
excluded from version control or moved to a template with no actual secret
value, and update deployment scripts to provide the real secret at deploy time.

Extract MongoDB credentials from the connection string into secrets.
The MONGODB_URI contains plaintext credentials (mongoadmin:secret123). Checkov flagged this as CKV_SECRET_4. Consider:
- Store MongoDB credentials in the secret alongside
jwt-secret - Construct the URI using multiple env vars or use init containers
Alternatively, use string interpolation with secret-backed env vars if the application supports it.

Rewrite-target will break API routing.
The rewrite-target: / annotation combined with path: "/api" will strip the /api prefix before forwarding to the backend. A request to /api/messages becomes /messages, but the backend routes are registered at /api/auth, /api/messages, and /health (see backend/src/index.js:32-34). This will result in 404 errors for all API requests.
Either:
- Remove the
rewrite-targetannotation entirely, or - Use a capture group pattern:

Missing storageClassName will prevent PVC binding.
Without an explicit storageClassName, this static PV won't bind to the PVC. When storageClassName is omitted, Kubernetes may try to use the cluster's default StorageClass for dynamic provisioning instead of binding to this static PV.
To bind a static PV without a StorageClass, set storageClassName: "" on both the PV and PVC.
Additionally, hostPath volumes are only suitable for single-node development clusters—data is tied to one node and won't survive node failures.

Avoid hardcoding database credentials.
MongoDB credentials (mongoadmin/secret123) are in plain text. These should be stored in a Kubernetes Secret (similar to how jwt-secret is handled) and referenced via secretKeyRef.
This also applies to the MONGODB_URI in backend-deployment.yaml which embeds the same credentials.

credentials: create a Kubernetes Secret (e.g., name it mongo-credentials)
containing keys for MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD
(and optionally a MONGODB_URI) and update the MongoDB Deployment to stop using
literal values — replace the env entries for MONGO_INITDB_ROOT_USERNAME and
MONGO_INITDB_ROOT_PASSWORD with valueFrom: secretKeyRef referencing the new
secret; likewise update the backend Deployment where MONGODB_URI is currently
embedded to either pull username/password from the same secret (and build the
URI from those env vars) or reference a MONGODB_URI key in the secret via
secretKeyRef so no credentials remain in plain text in the manifests.

Avoid committing secrets to version control.
The JWT secret is hardcoded in this manifest. Base64 encoding is not encryption—anyone with repository access can decode it. This exposes the secret and creates a security risk.
Consider using one of these approaches:
- Sealed Secrets: Encrypt secrets that can only be decrypted by the cluster
- External Secrets Operator: Sync secrets from external stores (AWS Secrets Manager, Vault, etc.)
- Helm with values injection: Pass secrets at deploy time from CI/CD pipelines
At minimum, ensure this file is in .gitignore and secrets are injected during deployment.

In `@k8s/secrets.yaml` around lines 1 - 8, The manifest k8s/secrets.yaml currently
contains a hardcoded base64 JWT secret (Secret name chatapp-secrets, key
jwt-secret, namespace chat-app); remove the secret value from the committed file
and replace the workflow with a secure injection pattern (e.g., convert to a
SealedSecret, configure External Secrets Operator to pull jwt-secret from your
secrets backend, or render the secret via Helm values at deploy time from
CI/CD). Also ensure k8s/secrets.yaml (or any file containing cleartext/base64
secrets) is excluded from version control or moved to a template with no actual
secret value, and update deployment scripts to provide the real secret at deploy
time.
