Cloudsmith is a platform for package promotion workflows that aim to isolate and protect production repositories away from public upstreams, ensuring only clear and vetted packages are received. This process utilizes Cloudsmith's package promotion instructions, symbiotic features such as webhooks, quarantining, and upstreaming, which can be combined to create workflows and drive actions. The platform supports multiple environments, including development, staging, and production, allowing developers to test and validate their code before releasing it to users. With multiformat repositories, vulnerability scanning, and upstream proxying, Cloudsmith facilitates automation of copying and moving packages between pipelines, reducing bandwidth costs and improving security. By setting up workflows with webhooks, users can automate tasks such as promoting packages based on scan results, and future policy management features will enable verification of prerequisites for package promotion.
