You can configure continuous integration (CI) and continuous deployment (CD) for individual services and jobs, or create combinations of build services with deployment services and jobs depending on your requirements.
Continuous integration can be configured to build each commit, or you can build from specific branches or pull requests. You can also configure advanced settings to only build when specific files or directories are updated, or to skip builds with certain commit messages.
Continuous deployment can be enabled to always roll out or run the latest build.
Using CI/CD with path rules and ignore flags allows you to manage your build and deployment workflow from development to production, automatically building and deploying only where desired and retaining manual control where needed.
For example, you could configure a build service with path rules, linked to a CD-enabled deployment service, to automatically build and deploy your frontend to preview changes immediately. You can then manually build and deploy your backend only when required. Add commit message ignore flags to skip building minor changes, and automatically build and deploy all your microservices when you want to test the pull request for your next release.
Use continuous integration
Continuous integration can be enabled on combined services, build services, and jobs that build from a repository as a source.
You can enable and disable CI using the toggle in the header of the service or job.
CI on a combined service
You can enable CI on a combined service so that any new commits to the linked repository branch will be built automatically. If you also enable CD, every new commit to the branch will be automatically built and deployed.
CI on a build service
You can enable CI on a build service to build any new commits to branches or pull requests that the service is configured to monitor.
You can combine this build service with one or more deployment services to create an effective workflow. For example, your build service could build both your development and production branches, and a deployment service with CD enabled could automatically deploy the latest development build. Another deployment service with CD disabled could then be used to manually deploy stable production builds when you are ready to release. You can also use the build service as a source for jobs.
CI on a job
If you create a job that has version control as the image source, you can configure CI and other build settings within the job. If you enable CI on a job, it will always build the latest commit to the linked branch. If you also enable CD, the job will use the latest build when a run is triggered.
Trigger builds with commits to specific files or directories
You can use path rules to trigger a build only when specific parts of your repository have been modified. You can either ignore directories or files containing code that you don't want to build in a specific job or service, or allow only the directories or files containing code that you want to build for a particular service or job.
Path rules can be configured from the build options page of a job or service, in advanced build settings under build type.
