Setting up a continuous integration and continuous deployment (CI/CD) pipeline might sound intimidating, but it’s a crucial step for streamlining your frontend development. GitLab CI/CD is an excellent tool for automating these processes, making your workflow smoother and more efficient. In this article, we’ll guide you through the steps to use GitLab CI/CD for your frontend projects, from basic setup to advanced configurations.
Understanding GitLab CI/CD
Before diving into the setup, let’s cover the basics. GitLab CI/CD is a tool integrated into GitLab that helps automate your development workflow. This includes running tests, building code, and deploying applications.
For frontend projects, this means you can automate tasks such as code linting, testing, building, and deploying your web applications.
Setting Up GitLab CI/CD
Create a GitLab Project
First, ensure you have a GitLab account and create a new project for your frontend application. If you already have a project, you can skip this step.
Log in to your GitLab account, navigate to the dashboard, and click on the “New Project” button. Fill in the project details, such as name and visibility level, then click on “Create Project.”
Add a .gitlab-ci.yml
File
The heart of GitLab CI/CD is the .gitlab-ci.yml
file. This configuration file defines your CI/CD pipeline, specifying what steps to execute and in what order.
In the root directory of your project, create a file named .gitlab-ci.yml
. This file will contain all the instructions GitLab needs to automate your workflow. Here’s a basic example:
stages:
- build
- test
- deploy
build:
stage: build
script:
- npm install
- npm run build
artifacts:
paths:
- build/
test:
stage: test
script:
- npm test
deploy:
stage: deploy
script:
- npm run deploy
only:
- main
This file defines three stages: build, test, and deploy. Each stage contains scripts that GitLab will execute. The artifacts
section in the build stage tells GitLab to save the build output for use in later stages.
The only
keyword in the deploy stage ensures that deployment happens only when changes are pushed to the main branch.
Configure Runners
GitLab CI/CD uses runners to execute the jobs defined in your .gitlab-ci.yml
file. Runners can be either shared or specific to your project.
To configure a runner, go to your GitLab project, click on “Settings,” then “CI/CD,” and expand the “Runners” section. You can either use the shared runners provided by GitLab or set up your own.
If you choose to set up your own runner, follow the instructions provided by GitLab to register it.
Define Your Stages
The stages in your .gitlab-ci.yml
file dictate the order in which jobs run. Each job belongs to a stage, and GitLab runs jobs in the same stage in parallel but runs stages sequentially.
For a typical frontend project, you might have stages like build, test, and deploy. Each of these stages should have jobs that perform specific tasks. For example, in the build stage, you might have a job that compiles your code and another that packages it.
Setting Up Build Jobs
The build job is responsible for compiling your frontend assets. Depending on your project, this might involve running a build tool like Webpack, Parcel, or Vite. Here’s an example of a build job configuration:
build:
stage: build
script:
- npm install
- npm run build
artifacts:
paths:
- dist/
In this example, npm install
installs your project’s dependencies, and npm run build
compiles your code. The artifacts
section specifies that the contents of the dist/
directory (where your build output is stored) should be saved and made available to subsequent stages.
Setting Up Test Jobs
Testing is a crucial part of any CI/CD pipeline. In the test stage, you’ll run your frontend tests to ensure your application behaves as expected. Here’s an example of a test job configuration:
test:
stage: test
script:
- npm test
This job simply runs npm test
, which should execute your test suite. You might also want to configure your test environment or use additional tools, depending on your testing setup.
Setting Up Deploy Jobs
Finally, the deploy stage handles deploying your application to your production environment. This could involve uploading files to a server, deploying to a cloud service, or running deployment scripts. Here’s a basic example:
deploy:
stage: deploy
script:
- npm run deploy
only:
- main
This job runs npm run deploy
, which should contain the instructions for deploying your application. The only
keyword ensures that deployment only occurs when changes are pushed to the main branch.
Advanced Configurations
Environment Variables
Environment variables are useful for managing sensitive data or configuration settings that change between environments (e.g., development, staging, production). GitLab allows you to define environment variables that can be used in your .gitlab-ci.yml
file.
To add environment variables in GitLab, go to your project, click on “Settings,” then “CI/CD,” and expand the “Variables” section. Here, you can add variables that will be available during your pipeline runs.
For example, if you need to store API keys or deployment credentials, you can add these variables and reference them in your .gitlab-ci.yml
file:
deploy:
stage: deploy
script:
- npm run deploy -- --api-key $API_KEY
only:
- main
In this example, $API_KEY
is an environment variable that is securely accessed during deployment.
Caching Dependencies
To speed up your pipeline, you can cache dependencies that don’t change often. For frontend projects, this typically includes package managers like npm or yarn. Caching reduces the time needed to install dependencies by storing them between pipeline runs.
Here’s how you can set up caching for npm dependencies:
cache:
paths:
- node_modules/
By adding this configuration to your .gitlab-ci.yml
file, GitLab will cache the node_modules/
directory. This way, you won’t need to reinstall packages on every pipeline run.
Using Multiple Runners
Sometimes, you might need different runners for different jobs. For example, you could have one runner for your build jobs and another for deployment jobs. GitLab allows you to define specific runners for different jobs by using tags.
To use specific runners, first, tag your runners. Then, in your .gitlab-ci.yml
file, specify the tags for each job:
build:
stage: build
tags:
- build-runner
script:
- npm install
- npm run build
deploy:
stage: deploy
tags:
- deploy-runner
script:
- npm run deploy
only:
- main
Using Docker with GitLab CI/CD
Docker can help create consistent environments across development and production. You can use Docker images in your GitLab CI/CD pipeline to ensure that your builds and tests run in a controlled environment.
Here’s an example of how to use a Docker image in your pipeline:
image: node:14
stages:
- build
- test
- deploy
build:
stage: build
script:
- npm install
- npm run build
test:
stage: test
script:
- npm test
deploy:
stage: deploy
script:
- npm run deploy
only:
- main
In this example, the image
keyword specifies that the node:14
Docker image should be used for all jobs. This ensures that your pipeline runs with Node.js 14 installed.
Parallel Jobs
To speed up your pipeline, you can run jobs in parallel. GitLab CI/CD allows jobs within the same stage to run concurrently. For instance, if you have multiple tests that can run independently, you can configure them to run in parallel.
test_unit:
stage: test
script:
- npm run test:unit
test_integration:
stage: test
script:
- npm run test:integration
In this example, test_unit
and test_integration
run concurrently during the test stage.
Manual Actions
Sometimes, you might need to perform manual actions in your pipeline, such as approving a deployment. GitLab CI/CD supports manual actions for such scenarios. You can define manual jobs that require user intervention before proceeding.
deploy_review:
stage: deploy
script:
- npm run deploy
when: manual
only:
- main
In this case, the deployment job will not run automatically but will require manual approval.
Best Practices
Keep Your Pipeline Simple
While GitLab CI/CD is powerful, it’s important to keep your pipeline configuration as simple as possible. Avoid overcomplicating your .gitlab-ci.yml
file with unnecessary stages or jobs. A straightforward pipeline is easier to maintain and debug.
Monitor Pipeline Performance
Regularly monitor the performance of your pipeline. GitLab provides detailed insights into pipeline runs, including duration and status. Use these insights to optimize your pipeline by identifying and addressing bottlenecks.
Secure Your Pipeline
Ensure that sensitive data such as API keys and passwords are stored securely using GitLab’s environment variables. Avoid hardcoding sensitive information in your .gitlab-ci.yml
file.
Test Locally
Before committing changes to your .gitlab-ci.yml
file, test it locally using tools like GitLab Runner. This helps catch errors and ensure your pipeline behaves as expected before pushing it to GitLab.
Keep Dependencies Updated
Regularly update your dependencies and pipeline configurations to keep up with new features and security updates. Outdated dependencies or configurations can lead to security vulnerabilities or broken builds.
Integrating GitLab CI/CD with Frontend Tools
Using GitLab CI/CD with Frontend Frameworks
GitLab CI/CD integrates seamlessly with popular frontend frameworks like React, Angular, and Vue.js. Each framework has its own build and deployment requirements, but GitLab CI/CD can handle them efficiently. Let’s look at how to configure your pipeline for different frameworks.
React
For a React project, you typically use create-react-app
or another build tool like Webpack. Here’s a sample .gitlab-ci.yml
for a React project:
image: node:16
stages:
- build
- test
- deploy
cache:
paths:
- node_modules/
build:
stage: build
script:
- npm install
- npm run build
artifacts:
paths:
- build/
test:
stage: test
script:
- npm test
deploy:
stage: deploy
script:
- npm run deploy
only:
- main
In this setup, the build
stage generates a production-ready build of your React application. The test
stage runs tests to ensure code quality, and the deploy
stage handles deployment.
Angular
Angular projects often use Angular CLI for building and testing. Here’s an example .gitlab-ci.yml
for an Angular project:
image: node:16
stages:
- build
- test
- deploy
cache:
paths:
- node_modules/
build:
stage: build
script:
- npm install
- ng build --prod
artifacts:
paths:
- dist/
test:
stage: test
script:
- ng test --watch=false
deploy:
stage: deploy
script:
- npm run deploy
only:
- main
This configuration builds the Angular application with ng build --prod
, runs tests with ng test
, and deploys the application.
Vue.js
Vue.js projects use Vue CLI, and here’s a sample .gitlab-ci.yml
file for Vue.js:
image: node:16
stages:
- build
- test
- deploy
cache:
paths:
- node_modules/
build:
stage: build
script:
- npm install
- npm run build
artifacts:
paths:
- dist/
test:
stage: test
script:
- npm run test
deploy:
stage: deploy
script:
- npm run deploy
only:
- main
This setup mirrors the configurations for React and Angular, but uses npm run build
specific to Vue.js.
Deploying to Different Environments
GitLab CI/CD allows you to deploy to various environments such as staging, production, or any custom environment. You can define these environments in your .gitlab-ci.yml
file.
Staging Environment
To deploy to a staging environment, you can add a stage and job specifically for staging:
stages:
- build
- test
- deploy
- deploy_staging
deploy_staging:
stage: deploy_staging
script:
- npm run deploy:staging
environment:
name: staging
only:
- develop
In this example, deploy_staging
deploys the application to a staging environment when changes are pushed to the develop
branch.
Production Environment
Deployment to production is usually done with more caution. Here’s how to set it up:
deploy_production:
stage: deploy
script:
- npm run deploy:production
environment:
name: production
only:
- main
This job deploys the application to production when changes are pushed to the main
branch.
Handling Deployments with Docker
If you’re using Docker, you might want to build and deploy Docker images in your CI/CD pipeline. Here’s how you can integrate Docker with GitLab CI/CD:
image: docker:20.10
services:
- docker:dind
stages:
- build
- push
- deploy
build:
stage: build
script:
- docker build -t my-app .
artifacts:
paths:
- docker-image.tar
push:
stage: push
script:
- docker tag my-app registry.example.com/my-app
- docker push registry.example.com/my-app
deploy:
stage: deploy
script:
- ssh user@server 'docker pull registry.example.com/my-app && docker run -d my-app'
only:
- main
In this example, the build
job creates a Docker image, the push
job uploads it to a Docker registry, and the deploy
job pulls and runs the image on your server.
Monitoring and Debugging Pipelines
Monitoring and debugging your CI/CD pipelines are essential for maintaining a healthy development workflow. GitLab provides several tools to help with this.
Pipeline Dashboard
The pipeline dashboard in GitLab provides an overview of your pipeline runs, including their status and duration. You can access it from your project’s “CI/CD” section. This view helps you quickly identify any failed pipelines and investigate issues.
Job Logs
Each job in your pipeline produces logs that show the output of the scripts being run. You can view these logs to understand what went wrong in case of failures. Clicking on a specific job will reveal detailed logs, which are invaluable for debugging.
Retry Jobs
If a job fails due to an intermittent issue, GitLab allows you to retry the job without rerunning the entire pipeline. This feature is accessible from the pipeline dashboard and can save time during troubleshooting.
Alerts and Notifications
GitLab can send notifications and alerts based on pipeline events. Configure these notifications to stay informed about pipeline failures or other important events. Notifications can be set up in your project’s settings under “Notifications.”
Best Practices for Pipeline Management
Regularly Review Pipeline Configurations
Periodically review your pipeline configurations to ensure they meet current project needs. As projects evolve, pipelines may require adjustments to optimize performance or add new features.
Use GitLab’s Built-In Features
Leverage GitLab’s built-in features such as Auto DevOps, which can automatically configure pipelines based on best practices. This can simplify your setup and help adhere to industry standards.
Optimize Pipeline Performance
Analyze and optimize pipeline performance by removing redundant steps or optimizing scripts. Monitor pipeline duration and make improvements to reduce build and deployment times.
Document Your CI/CD Processes
Maintain clear documentation for your CI/CD processes and pipeline configurations. This documentation will help new team members understand the setup and assist in troubleshooting issues.
Advanced Topics and Integration
Integrating with Other Tools
GitLab CI/CD can be integrated with a variety of other tools to enhance your development workflow. Here are some common integrations and how to set them up:
Code Quality Tools
Code quality tools help ensure that your code adheres to best practices and standards. Tools like ESLint for JavaScript or SonarQube for more comprehensive analysis can be integrated into your GitLab pipeline.
To integrate ESLint into your pipeline, you can add a job to run ESLint as part of your CI process:
eslint:
stage: test
script:
- npm install
- npx eslint .
For SonarQube, you would need to configure the SonarQube scanner and add a job to run the analysis:
sonarqube:
stage: test
script:
- sonar-scanner -Dsonar.projectKey=my-project -Dsonar.sources=. -Dsonar.host.url=$SONAR_HOST_URL -Dsonar.login=$SONAR_TOKEN
Make sure to add SONAR_HOST_URL
and SONAR_TOKEN
as environment variables in GitLab.
Notification Systems
To keep your team informed about pipeline statuses, you can integrate GitLab CI/CD with notification systems such as Slack or email.
For Slack notifications, you can use GitLab’s built-in Slack integration. Go to your project’s settings, find the “Integrations” section, and configure Slack notifications. You can choose to receive notifications for pipeline events, job status changes, and more.
For email notifications, GitLab sends default notifications for pipeline statuses. You can customize these notifications in your project’s settings under “Notifications.”
Deployment Services
GitLab CI/CD can deploy to various services and platforms, including cloud providers like AWS, Azure, and Google Cloud. Here’s how to configure deployments for these services:
AWS
To deploy to AWS, you might use AWS CLI commands within your deployment job:
deploy_aws:
stage: deploy
script:
- aws s3 sync build/ s3://my-bucket
- aws cloudfront create-invalidation --distribution-id YOUR_DISTRIBUTION_ID --paths "/*"
only:
- main
Make sure to configure AWS credentials as environment variables in GitLab.
Azure
For Azure deployments, you might use Azure CLI:
deploy_azure:
stage: deploy
script:
- az login --service-principal -u $AZURE_CLIENT_ID -p $AZURE_CLIENT_SECRET --tenant $AZURE_TENANT_ID
- az webapp deployment source config-zip --resource-group myResourceGroup --name myAppName --src build.zip
only:
- main
Configure AZURE_CLIENT_ID
, AZURE_CLIENT_SECRET
, and AZURE_TENANT_ID
as environment variables.
Google Cloud
For Google Cloud, you might use gcloud
commands:
deploy_gcloud:
stage: deploy
script:
- gcloud auth activate-service-account --key-file=$GOOGLE_APPLICATION_CREDENTIALS
- gcloud app deploy
only:
- main
Set GOOGLE_APPLICATION_CREDENTIALS
as an environment variable pointing to your service account key file.
Handling Secrets and Sensitive Data
Managing secrets securely is crucial for protecting your applications and data. Here’s how to handle secrets effectively in GitLab CI/CD:
Use GitLab’s Secret Management
GitLab offers built-in secret management through environment variables. You can define environment variables for secrets in your project’s settings:
- Go to “Settings” -> “CI/CD” -> “Variables.”
- Add variables for your secrets, such as API keys or database credentials.
These variables can then be referenced in your .gitlab-ci.yml
file:
deploy:
stage: deploy
script:
- echo $SECRET_KEY
Encrypt Sensitive Files
If you need to use sensitive files in your pipeline, such as private keys or configuration files, consider encrypting these files. You can store encrypted files in your repository and decrypt them during the pipeline:
- Encrypt the file locally using a tool like GPG or OpenSSL.
- Store the encrypted file in your repository.
- Decrypt the file as part of your pipeline script:
deploy:
stage: deploy
script:
- openssl aes-256-cbc -d -in secret.enc -out secret -k $DECRYPTION_PASSWORD
- deploy-command
Ensure that DECRYPTION_PASSWORD
is stored securely as an environment variable.
Customizing Pipeline Behavior
GitLab CI/CD allows extensive customization of pipeline behavior to fit specific needs. Here are a few customization options:
Conditional Jobs
You can conditionally run jobs based on certain criteria using rules
or only/except
clauses. For example, you might want to run specific jobs only for certain branches or tags:
deploy:
stage: deploy
script:
- deploy-command
rules:
- if: '$CI_COMMIT_BRANCH == "main"'
This job will only run if the commit branch is main
.
Pipeline Triggers
Pipeline triggers allow you to manually start pipelines with custom parameters. You can use this feature to trigger pipelines from external systems or scripts:
trigger:
stage: deploy
script:
- trigger-command
when: manual
You can start this job manually from the GitLab UI or trigger it via API.
Multi-Project Pipelines
In some cases, you might have multiple projects that need to be built or deployed together. GitLab supports multi-project pipelines, allowing you to trigger pipelines in other projects:
trigger_project:
stage: deploy
trigger:
project: my-group/my-other-project
branch: main
This job triggers a pipeline in another project when it runs.
Debugging and Troubleshooting
Debugging issues in your CI/CD pipeline can be challenging. Here are some strategies to help:
Analyze Logs
Pipeline logs provide detailed information about each job’s execution. Use these logs to identify where and why a job failed. Look for error messages or failed commands to guide your troubleshooting.
Use Debug Mode
You can run jobs in debug mode to get more detailed output. To enable debug mode, set the CI_DEBUG_TRACE
variable to true
in your .gitlab-ci.yml
file:
variables:
CI_DEBUG_TRACE: "true"
This will produce more verbose logs, which can help diagnose issues.
Test Locally
Consider running your pipeline jobs locally using GitLab Runner to replicate the CI environment. This can help identify issues that may not be apparent in the pipeline:
gitlab-runner exec shell <job_name>
This command runs the specified job locally, allowing you to test and debug in the same environment as the CI pipeline.
Keeping Pipelines Efficient
To maintain efficiency in your CI/CD pipeline, consider these practices:
Optimize Build Times
Reduce build times by caching dependencies, parallelizing jobs, and optimizing build scripts. Use caching effectively to avoid re-installing dependencies on every run.
Limit Job Artifacts
Only store necessary artifacts to avoid excessive storage usage. Define artifacts only for jobs that need to pass outputs to subsequent jobs:
artifacts:
paths:
- dist/
Regular Maintenance
Regularly review and update your .gitlab-ci.yml
file to remove outdated or redundant jobs and stages. This helps keep your pipeline efficient and relevant to current project requirements.
Handling Deployment Strategies
Blue-Green Deployment
Blue-Green deployment is a strategy where you have two identical environments: Blue and Green. One environment is live (e.g., Blue) and the other (e.g., Green) is idle or used for staging.
When you deploy a new version of your application, it’s deployed to the idle environment (Green). Once the deployment is complete and tested, you switch traffic from Blue to Green.
Setting Up Blue-Green Deployment in GitLab CI/CD
Here’s a basic approach to implement Blue-Green deployment:
stages:
- build
- deploy
build:
stage: build
script:
- npm install
- npm run build
artifacts:
paths:
- dist/
deploy_blue:
stage: deploy
script:
- aws s3 sync dist/ s3://my-blue-bucket
- aws cloudfront create-invalidation --distribution-id YOUR_DISTRIBUTION_ID --paths "/*"
environment:
name: blue
url: https://blue.example.com
only:
- main
deploy_green:
stage: deploy
script:
- aws s3 sync dist/ s3://my-green-bucket
- aws cloudfront create-invalidation --distribution-id YOUR_DISTRIBUTION_ID --paths "/*"
environment:
name: green
url: https://green.example.com
only:
- main
In this setup, deployments are pushed to separate S3 buckets for Blue and Green environments. You can switch traffic by updating DNS records or load balancer configurations.
Canary Deployment
Canary deployment involves deploying a new version of your application to a small subset of users before rolling it out to the entire user base. This helps in minimizing risk by allowing you to monitor the new version’s performance and detect issues early.
Setting Up Canary Deployment in GitLab CI/CD
Here’s a sample configuration for Canary deployment:
stages:
- build
- deploy
build:
stage: build
script:
- npm install
- npm run build
artifacts:
paths:
- dist/
deploy_canary:
stage: deploy
script:
- aws s3 sync dist/ s3://my-canary-bucket
- aws cloudfront create-invalidation --distribution-id YOUR_CANARY_DISTRIBUTION_ID --paths "/*"
environment:
name: canary
url: https://canary.example.com
only:
- main
deploy_production:
stage: deploy
script:
- aws s3 sync dist/ s3://my-production-bucket
- aws cloudfront create-invalidation --distribution-id YOUR_PRODUCTION_DISTRIBUTION_ID --paths "/*"
environment:
name: production
url: https://www.example.com
only:
- main
when: manual
In this configuration, the deploy_canary
job deploys to a canary environment where a small percentage of users can access the new version. The deploy_production
job deploys to production and requires manual approval to proceed, allowing time to monitor the canary deployment.
Rolling Deployment
Rolling deployment gradually replaces instances of the previous version of your application with the new version. This is useful for minimizing downtime and ensuring that users experience uninterrupted service.
Setting Up Rolling Deployment in GitLab CI/CD
Here’s a basic approach to rolling deployment:
stages:
- build
- deploy
build:
stage: build
script:
- npm install
- npm run build
artifacts:
paths:
- dist/
deploy:
stage: deploy
script:
- kubectl apply -f k8s/deployment.yaml
- kubectl rollout status deployment/my-app
environment:
name: production
url: https://www.example.com
only:
- main
In this setup, the deployment is managed using Kubernetes, where kubectl apply
updates the deployment configuration. The kubectl rollout status
command ensures that the rollout completes successfully.
Security Best Practices
Protecting Your Code
Ensure your code is secure by following these best practices:
Use Code Scanning Tools
Integrate code scanning tools to detect vulnerabilities and security issues in your codebase. Tools like Snyk or GitLab’s built-in security scanning features can help identify and address security flaws early.
security_scan:
stage: test
script:
- snyk test
Implement Access Controls
Restrict access to your GitLab project and CI/CD configurations based on roles and responsibilities. Use GitLab’s built-in user roles and permissions to control who can access and modify pipeline configurations.
Secure Your Docker Images
Ensure that Docker images used in your pipelines are free from vulnerabilities. Regularly scan your images for security issues using tools like Docker Bench or Clair.
Securing Secrets
Avoid Hardcoding Secrets
Never hardcode secrets or sensitive information directly in your .gitlab-ci.yml
file. Use GitLab’s environment variables or secrets management features to handle sensitive data securely.
Use Encrypted Storage
For sensitive files needed in your pipeline, store them in encrypted formats. Decrypt them only during the pipeline execution and avoid storing unencrypted secrets.
Regularly Update Dependencies
Keep your dependencies up to date to avoid vulnerabilities associated with outdated packages. Automate dependency updates using tools like Dependabot or Renovate, and incorporate them into your CI/CD pipeline.
Scaling and Optimizing Pipelines
Handling Large Repositories
Large repositories can slow down pipeline execution. Consider the following strategies to manage large repositories:
Use Git LFS
Git Large File Storage (LFS) helps manage large files in your repository efficiently. Configure Git LFS to handle large assets separately from the main repository.
Optimize Repository Size
Regularly clean up your repository to remove unnecessary files and reduce its size. Use Git’s built-in commands to remove large files from history if needed.
Parallelizing Jobs
Parallelizing jobs can significantly speed up your pipeline. Configure jobs to run concurrently where possible:
test:
stage: test
parallel:
matrix:
- NODE_VERSION: ["14", "16"]
script:
- npm test
This configuration runs tests with different Node.js versions in parallel, reducing overall pipeline time.
Optimizing Build Times
Use Incremental Builds
Where possible, use incremental builds to avoid rebuilding everything from scratch. Configure your build tools to use caching and incremental builds.
Cache Dependencies
Cache dependencies to avoid re-installing them on every pipeline run. Define cache paths in your .gitlab-ci.yml
to speed up builds:
cache:
paths:
- node_modules/
- .m2/repository/
Monitoring and Alerts
Set Up Alerts
Configure alerts to notify you of pipeline failures or other critical issues. Use GitLab’s built-in alerting features or integrate with external notification systems like PagerDuty or Opsgenie.
Monitor Pipeline Performance
Regularly review pipeline performance metrics and adjust configurations as needed. Use GitLab’s built-in analytics tools to track pipeline durations and identify areas for improvement.
