Earthly Show And Tell - CI Transformation with IOHK
Earthly ➤ https://earthly.dev
Welcome to another episode of Earthly Show and Tell. Today, Josh Gilman, the SRE lead at IOHK (Input Output), will take us on a deep dive into how his team has utilized Earthly to transform their CI process. In today's session, Josh will demonstrate how Earthly can simplify and streamline operations, even in a complex, monolithic repository like the one used to manage the Cardano blockchain.
Even if you're not currently using Earthly, this presentation will be beneficial to understand the potential of managing a large monorepo. Some key points we'll cover include:
The discovery mechanism that allows effortless onboarding of new projects without manual configuration.
A flexible yet opinionated target system with phases such as check, build, package, test, and release.
The use of the Earthly file as a primary interface for developers to interact with CI tools.
The challenges and solutions around caching in a large monorepo setup.
Josh brings a unique perspective on balancing developer productivity with operational concerns. This presentation promises to be a rich source of insights on handling large-scale development processes.
