13-17: Enhance Docker build stage with best practicesThe Docker build stage could be improved for better security and efficiency:
- Add build arguments for better configurability
- Implement proper image tagging strategy instead of using
latest- Add multi-stage builds if applicable to reduce final image size
stage("build and test"){ steps{ - sh "docker build -t node-app-test-new ." + script { + def BUILD_NUMBER = env.BUILD_NUMBER + sh """ + docker build \ + --build-arg NODE_ENV=production \ + --no-cache \ + -t node-app-test-new:${BUILD_NUMBER} \ + -t node-app-test-new:latest . + docker image prune -f + """ + } echo 'code build bhi ho gaya' } }
Line range hint
18-22: Implement proper image scanningThe current image scanning stage is just a placeholder. Consider implementing actual security scanning using tools like Trivy or Snyk.
stage("scan image"){ steps{ - echo 'image scanning ho gayi' + script { + def BUILD_NUMBER = env.BUILD_NUMBER + sh """ + docker run --rm -v /var/run/docker.sock:/var/run/docker.sock \ + aquasec/trivy image node-app-test-new:${BUILD_NUMBER} \ + --exit-code 1 \ + --severity HIGH,CRITICAL + """ + } } }
Line range hint
23-33: Improve Docker Hub authentication securityWhile using withCredentials is good, the current implementation exposes credentials through process environment. Consider using docker login --password-stdin.
stage("push"){ steps{ withCredentials([usernamePassword(credentialsId:"dockerHub",passwordVariable:"dockerHubPass",usernameVariable:"dockerHubUser")]){ - sh "docker login -u ${env.dockerHubUser} -p ${env.dockerHubPass}" + script { + def BUILD_NUMBER = env.BUILD_NUMBER + sh """ + echo "${dockerHubPass}" | docker login -u "${dockerHubUser}" --password-stdin + docker tag node-app-test-new:${BUILD_NUMBER} ${dockerHubUser}/node-app-test-new:${BUILD_NUMBER} + docker push ${dockerHubUser}/node-app-test-new:${BUILD_NUMBER} + docker tag node-app-test-new:${BUILD_NUMBER} ${dockerHubUser}/node-app-test-new:latest + docker push ${dockerHubUser}/node-app-test-new:latest + """ + } - sh "docker tag node-app-test-new:latest ${env.dockerHubUser}/node-app-test-new:latest" - sh "docker push ${env.dockerHubUser}/node-app-test-new:latest" echo 'image push ho gaya' } } }
Line range hint
34-39: Enhance deployment stage with health checksThe current deployment lacks proper health checks and rollback mechanisms.
stage("deploy"){ steps{ - sh "docker-compose down && docker-compose up -d" + script { + sh """ + docker-compose down + docker-compose up -d + # Wait for application to be ready + timeout 60s bash -c 'while [[ "$(curl -s -o /dev/null -w ''%{http_code}'' localhost:8000/health)" != "200" ]]; do sleep 5; done' + """ + } echo 'deployment ho gayi' } }
Line range hint
1-40: Add error handling and cleanup stagesThe pipeline lacks proper error handling, post-action cleanup, and professional logging.
Consider adding:
- Post stages for cleanup
- Error handling for each stage
- Professional logging messages
- Timeout configurations
Example structure:
pipeline { agent { label "dev-server" } options { timeout(time: 1, unit: 'HOURS') disableConcurrentBuilds() } environment { APP_NAME = 'node-todo-app' DOCKER_IMAGE = 'node-app-test-new' } stages { // ... existing stages with error handling ... } post { always { cleanWs() sh 'docker system prune -f' } success { echo "Pipeline completed successfully" } failure { echo "Pipeline failed" } } }views/todo.ejs (4)
Line range hint
78-89: Add CSRF protection to the form submissionThe form submission endpoint
/todo/add/lacks CSRF protection, which could make it vulnerable to cross-site request forgery attacks.Consider implementing CSRF protection using a token:
<form action="/todo/add/" method="post"> + <input type="hidden" name="_csrf" value="<%= csrfToken %>"> <p> <label for="newtodo">What should I do?</label>
Line range hint
71-77: Fix potential XSS vulnerability in todo itemsUsing
<%- todo %>for unescaped output could lead to XSS attacks if todo items contain malicious HTML/JavaScript.Replace with escaped output:
- <%- todo %> + <%= todo %>
Line range hint
70-70: Add ARIA labels to improve accessibilityThe edit and delete buttons lack proper accessibility labels, making it difficult for screen readers to convey their purpose.
Add ARIA labels to the action buttons:
- <a href="/todo/delete/<%= index %>" class="delete-btn">✘</a> - <a href="/todo/<%= index %>" class="edit-btn">✎</a> + <a href="/todo/delete/<%= index %>" class="delete-btn" aria-label="Delete todo item">✘</a> + <a href="/todo/<%= index %>" class="edit-btn" aria-label="Edit todo item">✎</a>
Line range hint
69-69: Consider making the heading configurableThe heading "Hello Junoon Batch 8 (Jenkins)" appears to be hardcoded, which might need to be updated for different batches or contexts.
Consider making it configurable through template variables:
- <h1>Hello Junoon Batch 8 (Jenkins), Write your plan on Learning Jenkins</h1> + <h1><%= pageTitle %></h1>

🧹 Nitpick (assertive)
Maintain consistent terminology and improve document structure
- Use consistent hyphenation: "To-Do" instead of "Todo"
- Use a single top-level heading (remove the duplicate heading at line 285)

Add security considerations for Docker group membership
Adding Jenkins user to the Docker group effectively grants root access. Consider:
- Adding a security warning about this implication
- Suggesting alternative approaches like running Jenkins in a container
- Implementing proper access controls

🛠️ Refactor suggestion
Enhance pipeline robustness and maintainability
The pipeline script could be improved:
- Use pipeline parameters instead of hardcoding the repository URL
- Add proper error handling for each stage
- Use meaningful status messages

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
