WalkthroughThe changes reorganize the CI/CD pipeline (Jenkinsfile) with renamed stages and updated method calls, update the Docker image reference in the deployment manifest (docker-compose.yml), and add formatting to documentation (README.md). Repository URL is changed from LondheShubham153 to ajaysingh3200 for code cloning. Changes

12-12: Update repository URL to match pipeline changes.The clone URL still references the old repository (LondheShubham153). The Jenkinsfile has been updated to use ajaysingh3200, so the README documentation should be consistent.

31-32: Minor formatting addition approved.The decorative separator is a cosmetic enhancement with no functional impact.

7-13: Approve Hello stage structure.The new Hello stage is cleanly implemented and follows the same pattern as other stages. The hello() function call via the Shared library is consistent with the library import.
14-20: Code stage correctly updated with new repository reference.The Code stage now clones from "https://github.com/ajaysingh3200/django-notes-app.git", which aligns with the PR objectives and docker-compose.yml image reference.
35-40: Verify Deploy stage docker compose commands and target environment.The Deploy stage now runs
docker compose down && docker compose up -ddirectly instead of calling a deploy() function. Ensure:
- Docker Compose is installed on the "vinod" agent
- The docker-compose.yml file is present in the current working directory at deploy time
- Proper error handling exists (the && operator means docker compose up only runs if down succeeds)
Consider adding explicit error handling and logging to the Deploy stage for better visibility into deployment failures:
stage("Deploy") { steps { echo "Deploying the application" - sh "docker compose down && docker compose up -d" + sh """ + echo "Stopping previous containers..." + docker compose down || true + echo "Starting new containers..." + docker compose up -d + echo "Deployment completed successfully" + """ } }The
|| trueallows the pipeline to continue even if down fails (useful if containers don't exist), and explicit echo statements improve observability.
21-27: Shared library function cannot be verified from repository code aloneThe search results show that
docker_buildis called at line 24 of the Jenkinsfile with three parameters as stated in the review. However, the function is defined in the external Jenkins Shared library (imported via@Library("Shared") _at line 1), not within this repository.The function definition does not exist in the current codebase, which is expected behavior for Jenkins Shared libraries. To verify:
- That the function exists in the Shared library
- That it accepts these three parameters in the specified order
- That the parameter types and order are correct
You will need to:
- Review the Shared library source code (typically in a separate repository or Jenkins configuration)
- Check the library's documentation or API specifications
- Confirm the
docker_buildfunction signature matches the call at line 24
28-34: Shared library dependency cannot be verified from this repository.The Jenkinsfile imports the external "Shared" library via
@Library("Shared") _and callsdocker_push("notes-app","latest","ajaysingh3200")with three parameters. The code structure is consistent:docker_builduses the identical three-parameter signature in the Build stage. However, since the Shared library is external and not present in this repository, I cannot confirm that thedocker_pushfunction exists in it or verify its exact signature.The developer must verify that the Shared library repository contains the
docker_pushfunction with this signature.docker-compose.yml (1)
19-19: Docker image tag consistency verified as correct.The Jenkinsfile's docker_push function (line 31) explicitly tags the image as "ajaysingh3200/notes-app:latest", which matches the docker-compose.yml reference to "ajaysingh3200/notes-app" (implicit "latest" default). Tag consistency across the build and deployment pipeline is verified and correct. No changes required.

Verify shared library configuration and agent availability.
The pipeline depends on functions from the "Shared" library (hello, docker_build, docker_push). Ensure these functions are defined in your Jenkins shared library with matching signatures. Additionally, verify that the agent label "vinod" is configured and available in your Jenkins environment.

Fix indentation inconsistencies throughout the pipeline.
The Jenkinsfile imports an external Shared library ("Shared") that cannot be verified within this repository—you must confirm the required functions (hello, clone, docker_build, docker_push) exist and have matching signatures in your Jenkins controller configuration. The agent label "vinod" must also be verified in your Jenkins environment.
However, there are indentation issues in the current Jenkinsfile that should be corrected:
- Line 8:
steps {block under stage("Hello") is misaligned - Lines 9-10:
scriptandhello()indentation inconsistent - Lines 17-19:
clone()call and closing braces over-indented (extra spaces) - Lines 29-33:
steps,script, anddocker_push()indentation misaligned
Reformat these sections to align with Groovy pipeline conventions (consistent 4-space indentation per nesting level).
🤖 Prompt for AI Agents
In Jenkinsfile (lines 1-4, and specifically adjust blocks at lines 8-10, 17-19,
29-33): fix inconsistent indentation by using 4 spaces per nesting level
throughout the declarative pipeline; align the stage("Hello") block so "steps
{", the nested "script {", and the "hello()" call share consistent 4-space
increments, remove the extra leading spaces before the "clone()" call and its
closing braces so they align with their parent "steps" block, and reformat the
docker stage so "steps", "script", and "docker_push()" are indented consistently
by 4 spaces per level; also verify externally referenced Shared library
functions (hello, clone, docker_build, docker_push) and the agent label "vinod"
exist in your Jenkins controller configuration.
