This tutorial shows you how to build a serverless continuous integration/continuous deployment (CI/CD) pipeline for Salesforce using Salesforce Developer Experience (SFDX) and Cloud Build. Cloud Build pipelines use containerization. The pipelines run builds as a series of build steps, where each build step is run in a Docker container. The pipeline can scale up and down in response to load with no need to pre-provision servers, and it offers fast, consistent, automated builds.
