Update Jenkinsfile
WalkthroughThe Jenkins pipeline script was restructured with updated agent configuration, stage renaming, repository and image references, credential usage, and Docker commands. A new test stage was introduced, and the deploy stage was modified to use "docker-compose" with adjusted flags. No changes were made to exported or public code entities. Changes

1-2: Agentanymay land on nodes without Docker / Compose — keep the label restriction or addtools/dockerchecks.By switching from
agent { label 'dev-server' }toagent any, the pipeline could land on a Jenkins executor that does not have Docker + docker-compose installed or properly configured (e.g. Docker socket not mounted). Builds will then fail at runtime.A quick safeguard:
agent { label 'docker-enabled' // or revert to 'dev-server' }Or declare a
tool/containerthat guarantees Docker CLI availability.

🧹 Nitpick (assertive)
Use docker.withRegistry instead of manual login / logout to keep credentials masked.
The current echo "$dockerHubPassword" | docker login … works but leaks the full command (with masked password) into build logs and is easy to forget to logout. Jenkins’ Docker Pipeline plugin wraps this safely:
stage('Push') {
steps {
script {
docker.withRegistry('', 'dockerHub') {
docker.image(IMAGE_TAG).push()
}
}
}
}This also avoids remembering variable names.

In Jenkinsfile lines 17 to 25, replace the manual docker login, push, and logout
commands with the Jenkins Docker Pipeline plugin's docker.withRegistry method to
keep credentials masked and avoid leaking sensitive info in logs. Use
docker.withRegistry with the credentialsId 'dockerHub' and call
docker.image(IMAGE_TAG).push() inside it, removing the explicit echo login and
logout commands. This also simplifies the code by not requiring manual
environment variable handling.

🛠️ Refactor suggestion
Hard-coding branch & repo limits reuse; parameterise or use checkout scm.
– Branch is fixed to master while the repo appears to use GitHub’s default main.
– Fork/PR builds will still clone the original repo instead of the one that triggered the job.
Consider:
parameters { string(name: 'GIT_REF', defaultValue: 'main') }
stage('Code') {
steps {
checkout([$class: 'GitSCM',
branches: [[name: params.GIT_REF]],
userRemoteConfigs: [[url: env.GIT_URL]]])
}Or simply checkout scm inside a multibranch pipeline.

In Jenkinsfile lines 5 to 8, the git clone step hard-codes the repository URL
and branch, limiting flexibility and causing issues with forks or PR builds.
Replace the fixed git step with a parameterized checkout using either a pipeline
parameter for the branch and environment variable for the repo URL, or simply
use 'checkout scm' if this is a multibranch pipeline. This will allow the
pipeline to dynamically use the correct repository and branch triggering the
build.

Test stage is a stub; run real tests or remove the stage.
An echo does not validate the build. At minimum:
-echo "Testing the new build .."
+sh 'npm ci'
+sh 'npm test -- --coverage'Failing to add tests undermines the value of CI.

In Jenkinsfile around lines 29 to 33, the 'Test' stage currently only echoes a
message and does not run any actual tests, which does not validate the build.
Replace the echo step with commands to execute real tests relevant to the
project, such as running unit tests or integration tests using the appropriate
test runner. If no tests are available yet, remove the 'Test' stage entirely to
avoid misleading CI feedback.

🛠️ Refactor suggestion
docker-compose down && up causes full downtime; consider up -d --pull always --build.
Running down tears down containers first, leading to user-visible outage. Prefer an in-place recreate:
-sh "docker-compose down && docker-compose up -d"
+sh "docker-compose pull && docker-compose up -d --remove-orphans --force-recreate"Also decide whether you rely on the standalone docker-compose binary (deprecated) or the newer docker compose sub-command; keep it consistent with your server’s version.

In Jenkinsfile lines 35 to 38, replace the current 'docker-compose down &&
docker-compose up -d' command with 'docker compose up -d --pull always --build'
to avoid full downtime by performing an in-place container recreate. Also,
verify and consistently use either the standalone 'docker-compose' binary or the
newer 'docker compose' sub-command based on the server's Docker version.

🛠️ Refactor suggestion
Image tag is always latest; add a unique tag to avoid overwriting good builds.
Pushing every commit as latest destroys the previous image and breaks roll-back. Append the Git SHA or build number:
-sh 'docker build . -t mohityadv/node-todo-test:latest'
+script {
+ IMAGE_TAG = "mohityadv/node-todo-test:${env.BUILD_NUMBER}"
+}
+sh "docker build . -t ${IMAGE_TAG}"Then push ${IMAGE_TAG} & optionally retag latest.

In Jenkinsfile around lines 11 to 13, the Docker image is always tagged as
'latest', which overwrites previous builds and prevents rollbacks. Modify the
Docker build command to tag the image with a unique identifier such as the Git
commit SHA or build number by defining an IMAGE_TAG variable. Then use this
IMAGE_TAG in the docker build and docker push commands, and optionally retag the
image as 'latest' for convenience.
