🛠️ Refactor suggestion
Improve Git checkout configuration.
Several improvements are recommended for the Code Clone stage:
- Use
checkout scminstead of explicit git step for Pipeline projects - Clean workspace before checkout
- Use parameters for branch selection instead of hard-coding
- stage("Code Clone") {
+ stage("Checkout") {
steps {
- echo "Code Clone Stage"
- git url: "https://github.com/shailesh271997/Springboot-BankApp.git", branch: "nginx-setup"
+ cleanWs()
+ checkout scm
}
}If you need to keep the explicit git step, consider using parameters:
parameters {
string(name: 'BRANCH_NAME', defaultValue: 'nginx-setup', description: 'Git branch to build')
}| pipeline { | ||
| agent { label 'spring-server' } | ||

🛠️ Refactor suggestion
Add timeout and resource constraints to the pipeline.
Consider adding pipeline-level timeout and resource constraints to prevent hung builds and resource exhaustion:
pipeline {
agent { label 'spring-server' }
+ options {
+ timeout(time: 1, unit: 'HOURS')
+ }
+ resources {
+ memory '2048Mi'
+ cpu '500m'

Improve deployment reliability and add health checks.
The current deployment strategy has several concerns:
- No health checks after deployment
- No rollback strategy
- Potential downtime during deployment
- No verification of docker-compose.yml
stage("Deploy") {
steps {
- sh "docker compose down && docker compose up -d --build"
+ script {
+ try {
+ // Verify docker-compose.yml exists
+ sh '[ -f docker-compose.yml ] || (echo "docker-compose.yml not found" && exit 1)'
+
+ // Rolling update to avoid downtime
+ sh '''
+ docker compose pull
+ docker compose up -d --no-deps --build app
+
+ # Wait for health check
+ timeout 60s bash -c 'until curl -s http://localhost:8080/actuator/health | grep -q "UP"; do sleep 5; done'
+ '''
+ } catch (Exception e) {

Enhance build stage with tests and proper versioning.
The current build stage has several missing components:
- No actual tests are being run despite the stage name
- No version tagging strategy
- No build caching optimization
stage("Code Build & Test") {
steps {
- echo "Code Build Stage"
- sh "docker build -t springboot-bankapp ."
+ script {
+ def version = env.BUILD_NUMBER
+ // Run tests
+ sh "./mvnw clean test"
+ // Build with proper tags and cache
+ sh """
+ docker build \
+ --cache-from springboot-bankapp:latest \
+ -t springboot-bankapp:${version} \
+ -t springboot-bankapp:latest \
+ --build-arg VERSION=${version} \
+ .
+ """
+ }
}

🛠️ Refactor suggestion
Add security scanning and error handling to Docker push stage.
The current stage needs security and reliability improvements:
- Add vulnerability scanning before pushing
- Add error handling
- Clean up local images after push
- Use specific registry URL instead of default Docker Hub
stage("Push To DockerHub") {
steps {
- withCredentials([usernamePassword(
- credentialsId: "dockerHubCreds",
- usernameVariable: "dockerHubUser",
- passwordVariable: "dockerHubPass")]) {
- sh 'echo $dockerHubPass | docker login -u $dockerHubUser --password-stdin'
- sh "docker image tag springboot-bankapp ${env.dockerHubUser}/springboot-bankapp:latest"
- sh "docker push ${env.dockerHubUser}/springboot-bankapp:latest"
+ script {
+ def version = env.BUILD_NUMBER
+ try {
+ // Scan for vulnerabilities
+ sh "trivy image springboot-bankapp:${version}"
+
+ withCredentials([usernamePassword(
+ credentialsId: "dockerHubCreds",
+ usernameVariable: "dockerHubUser",
+ passwordVariable: "dockerHubPass")]) {
+ sh '''
+ echo $dockerHubPass | docker login -u $dockerHubUser --password-stdin docker.io
+ docker image tag springboot-bankapp:${version} docker.io/${dockerHubUser}/springboot-bankapp:${version}
+ docker image tag springboot-bankapp:${version} docker.io/${dockerHubUser}/springboot-bankapp:latest
+ docker push docker.io/${dockerHubUser}/springboot-bankapp:${version}
+ docker push docker.io/${dockerHubUser}/springboot-bankapp:latest
+ '''
+ }
+ } catch (Exception e) {
+ error "Failed to push image: ${e.message}"
+ } finally {
+ sh 'docker logout'
+ // Clean up local images
+ sh "docker rmi springboot-bankapp:${version} || true"
+ }
}
