src/main/resources/templates/transactions.html (1)
116-117: Review the updated conditional logic for transaction display.
The updated expressions now usetransaction.type.contains('Transfer In') || transaction.type == 'Deposit', which is acceptable if transaction type strings might include additional characters. However, please ensure that:
- Null Safety:
transaction.typeis guaranteed to be non-null. If there’s any chance it could be null, consider applying a safe navigation approach (e.g., using the?.operator if your Thymeleaf/SPEL version supports it) or enforcing non-null values in your data.- DRY Principle: Since the same condition is used for both setting the CSS class and determining the display string, consider the maintainability benefit of extracting this logic into a local variable (inside the
th:eachloop) if Thymeleaf syntax permits. This will help to avoid inconsistencies in future changes.

Dockerfile (2)
1-10: Multi-stage Docker Build Setup Looks Good, but CMD Needs CorrectionThe multi-stage build is well defined. However, in the CMD instruction (line 17), the jar file is specified incorrectly as
"/src/target/* /src/target/bankapp.jar". This likely causes the container to attempt to run an invalid jar path. Please update the CMD to reference the built jar directly, for example:-CMD [ "java","-jar","/src/target/* /src/target/bankapp.jar" ] +CMD [ "java", "-jar", "/src/target/bankapp.jar" ][tag: request_verification][tag: suggest_essential_refactor]
11-17: COPY Instruction May Need a More Specific TargetThe COPY command on line 15 uses a wildcard and copies all files from
/src/target/into a destination file/src/target/bankapp.jar. This might work if only one jar is produced, but it could lead to unpredictable behavior if multiple files match. Consider copying the jar by name (if predictable) or adjust the destination directory.-COPY --from=builder /src/target/* /src/target/bankapp.jar +COPY --from=builder /src/target/bankapp.jar /app/bankapp.jarEnsure the CMD is updated accordingly if you change the location.

1-18: Terraform AWS Provider and VPC Configuration Looks CorrectThe configuration properly defines the required AWS provider and sets up a basic VPC resource with a CIDR block. Consider adding tags or additional configuration parameters to the VPC for improved resource tracking and management if needed.
[tag: approve_code_changes].gitignore (1)
32-38: Terraform Artifact Ignores Are Set AppropriatelyThe additions to ignore Terraform state and provider files (lines 34–38) are appropriate for keeping sensitive or machine-specific files out of version control. This helps maintain a clean repository.
[tag: approve_code_changes]Terraform/variable.tf (3)
1-4: AWS Region, AMI, and Instance Type Variables Are Well DefinedThe variables for AWS region, AMI, and instance type are clear and include descriptive text. This aids in understanding and future maintenance.
[tag: approve_code_changes]
11-14: Instance Type Variable Is ClearThe variable
instance_typeis properly defined with a default value oft2.large. This promotes flexibility for instance configuration.
[tag: approve_code_changes]
16-19: Typo in Variable Name & Possible RedundancyThe variable name
my_enviromentappears to be a misspelling of "environment". Additionally, its description is identical toinstance_type. Verify if both variables are needed or if one should be corrected/removed to avoid confusion. Consider renaming it tomy_environmentfor clarity.
[tag: suggest_nitpick]Terraform/main.tf (5)
1-12: AMI Data Source Configuration Looks SolidThe AWS AMI data source is correctly configured to retrieve the most recent Ubuntu image based on the provided filters. This ensures that the EC2 instance uses a valid and updated image.
[tag: approve_code_changes]
14-17: Key Pair Resource Is Configured ProperlyThe key pair resource is straightforward and correctly references an external public key file. Ensure that the file
bank-app-automate-key.pubexists in the correct location.
[tag: approve_code_changes]
19-21: Default VPC Resource ConsiderationThe resource block for
aws_default_vpcis empty. If the default VPC does not require additional configuration, this is acceptable. However, consider adding tags or validations if required for your environment.
[tag: suggest_good_to_have_refactor]
23-62: Security Group Configuration Is ComprehensiveThe security group
allow_user_to_connectincludes necessary ingress rules for ports 22, 80, and 443, and allows all outbound traffic. The configuration is clear and tagged appropriately. As a best practice, consider using specific IP ranges or tightening egress rules if possible, depending on your security requirements.
[tag: approve_code_changes]
64-77: EC2 Instance Resource Needs Enhanced Security ConfigurationThe EC2 instance is configured using
var.my_enviromentfor its instance type, which ties back to the earlier noted typo. More importantly, a static analysis tool highlighted that Instance Metadata Service (IMDS) v1 might be enabled by default. It is recommended to enforce IMDSv2 for enhanced security. Consider adding the following configuration:resource "aws_instance" "testinstance" { ami = data.aws_ami.os_image.id - instance_type = var.my_enviroment + instance_type = var.my_enviroment key_name = aws_key_pair.deployer.key_name security_groups = [aws_security_group.allow_user_to_connect.name] tags = { Name = "Bank-app-automation-server" } + metadata_options { + http_tokens = "required" + } root_block_device { volume_size = 30 volume_type = "gp3" } }This update forces the use of Instance Metadata Service Version 2 by requiring tokens.

6-17: PersistentVolume Specification is Sound.
The capacity, volume mode, access modes, reclaim policy, storage class, and hostPath configuration are all appropriately set for a persistent volume.kubernetes/bankapp-ingress.yml (3)
1-10: Ingress Metadata & Annotations Are Well-Configured
The API version, kind, and metadata (including useful annotations for rewrite, proxy body size, and SSL redirection) are properly defined. Please ensure that the referenced domain and TLS-related secret (bankapp-tls-secret) are created and managed correctly in the target namespace.
11-16: TLS Configuration Accuracy
The TLS settings correctly list the host and reference the designated secret. Verify that the secret exists and that Cert-Manager properly handles certificate issuance using the specifiedletsencrypt-prodcluster issuer.
17-27: Ingress Rules & Backend Service Consistency
The rules section cleanly routes traffic from the defined host to thebankapp-serviceon port 8080. Double-check that the service name and port number match the actual service deployed in the cluster to avoid routing mismatches.kubernetes/mysql-deployment.yml (2)
9-22: Container & Environment Specification
The MySQL container uses a stablemysql:8.0image, exposes the correct port, and sources necessary environment variables (e.g.,MYSQL_ROOT_PASSWORDfrom a Secret andMYSQL_DATABASEfrom a ConfigMap). This ensures better security and centralized configuration management.
34-41: Volume Mount & Persistence Setup
The volume mount correctly maps the MySQL data directory using a specific subPath for organization, and the persistent volume claim (mysql-pvc) is referenced properly. This configuration is crucial for data persistence across pod restarts.kubernetes/configmap.yaml (1)
1-10: ConfigMap for Application Configuration
The ConfigMap clearly defines the key-value pairs required by the application (database name, JDBC URL, and username). Ensure these values consistently match the expectations in your deployments to avoid configuration drift.kubernetes/bankapp-deployment.yml (3)
1-8: Deployment Metadata & Label Consistency
The metadata, including labels and namespace information, is clearly defined, which will help with proper pod selection and service binding.
23-43: Environment Variable Sourcing

Invalid Namespace Field in PersistentVolume.
PersistentVolume resources are cluster-scoped, so specifying a namespace (bankapp-namespace) is not applicable and may lead to unexpected behavior. Please remove the namespace entry from the metadata.

1-7: Metadata and Deployment Identification
The metadata section properly defines the deployment with a clear name (bankapp-deploy), appropriate labels, and the specified namespace (bankapp-namespace). This alignment ensures that the deployment is easily identifiable and correctly scoped.
8-12: Deployment Spec and High Availability
The replica count is explicitly set to 2 to maintain high availability, and the selector'smatchLabelscorrectly matches the pod template’s labels. This setup should reliably manage pod selection.
13-17: Pod Template Consistency
The pod template metadata correctly mirrors the deployment’s label settings, ensuring that the pods are accurately targeted by the deployment’s selector.
18-23: Container Configuration
The container namedbankappis configured with the Docker image9767913548/bankapp-eks:v2and exposes port 8080 as expected. Double-check that the image tag (v2) fits your release and rollback strategies.
24-43: Environment Variable Setup
The environment variables are correctly sourced usingconfigMapKeyRefforSPRING_DATASOURCE_URL,SPRING_DATASOURCE_USERNAME, andMYSQL_DATABASE, andsecretKeyRefforSPRING_DATASOURCE_PASSWORD. Ensure that the referenced ConfigMap (bankapp-config) and Secret (mysql-secret) are correctly maintained and updated.
56-62: Resource Allocation
The resource requests and limits are defined to manage CPU and memory usage for the container effectively. Monitoring resource utilization post-deployment will ensure that these values remain appropriate for the workload.
