Continuous packaging brings consistency and order to the steps between CI and CD, minimizing or eliminating ad hoc processes, bespoke scripts, unlogged manual procedures, and the use of libraries and packages without knowing their origins.
Continuous Packaging and CI/CD
The modern software development workflow is a DevOps pipeline that uses CI/CD to manage software delivery at scale. With continuous packaging, the CI/CD pipeline falls into three major phases:
- Continuous integration
- Developers write code that is continuously scanned and integrated before being packaged and pushed to a universal package repository.
- Continuous packaging
- All packages produced or consumed by the software supply chain are scanned, verified, and isolated from untrusted sources.
- Continuous delivery
- Packages are promoted through a series of tests, then delivered to customers where they can be deployed on customer or cloud infrastructure.
CI tools take source code changes as they come in, resolving dependencies on other packages or libraries, and build artifacts to be consumed by the CD tools. CI enforces consistency and automates integration, helping reduce problems such as code ...
