Solomon Hykes, the co-founder of Dagger and the creator of Docker, shares his insights on revolutionizing CI/CD. He delves into Dagger's innovative approach to simplifying continuous integration processes, addressing traditional tool limitations. The conversation also highlights the importance of code sharing through the Daggerverse, emphasizing trust and community in development. Hykes discusses the relationship between Dagger and infrastructure management, exploring how they can complement each other in enhancing developer workflows.
Dagger aims to enhance CI/CD processes by enabling pipelines to run in containers, ensuring consistency across development and production environments.
The platform introduces a declarative API that allows developers to create pipelines as graphs, promoting concurrent execution of functions instead of using traditional configuration languages.
Dagger emphasizes community-led growth through the 'Daggerverse,' enabling users to share and reuse pipeline components, fostering collaboration and innovation.

Kubernetes Configuration Updates
The transition to V1 Beta 4 of Kubernetes introduces changes to the configuration file necessary for deployment using kubeadm. The previous version, V1 Beta 3, has been officially deprecated and will be phased out after three more minor versions of Kubernetes. The latest release cycle for Kubernetes began on September 9, 2024, with expectations for the stable release to occur on December 11, 2024. This update is crucial for developers and operators managing Kubernetes implementations, as staying current with versioning will ensure better support and functionality.
CI/CD Challenges and Dagger's Approach
Solomon Hikes describes Dagger as a solution aimed at improving the continuous integration and delivery (CI/CD) process, which is often messy and cumbersome for software teams. He highlights that traditional CI tools tend to compound issues over time, becoming difficult to manage and update, especially as team members change. Dagger seeks to streamline these processes by enabling pipelines to run in containers anywhere, ensuring consistency between local development and production environments. This parallel draws on Docker's initial success, which solved similar problems for application deployment.
The Importance of Declarative APIs in Pipelines
The design of Dagger revolves around the need for a more intuitive way to define CI/CD pipelines through a declarative API. This allows developers to describe their pipelines as graphs where each step is a function that can run concurrently, rather than relying solely on configuration languages like YAML. By doing so, Dagger allows teams to iterate on their CI/CD processes more fluidly, without the 'push and pray' that often accompanies traditional methods. This new approach resembles the evolution seen with the introduction of Docker, allowing clearer, more portable application delivery.
Community-Driven Development and Daggerverse
Dagger also places significant emphasis on community-led growth, encouraging the sharing of functions or modules across its user base through what's termed the 'Daggerverse.' This platform indexes community-shared pipeline components, encouraging collaboration and reuse instead of reinventing the wheel. By allowing developers to package their Dagger functions as modules, they can leverage existing code and streamline their pipeline creation process. This ecosystem not only fosters innovation but also provides a source of trust, as users can review the visible source code instead of relying on opaque binaries.
Integration with Infrastructure as Code (IaC)
While discussing Dagger's role in the development landscape, Hikes clarifies that Dagger is not intended to be an infrastructure as code (IaC) platform, but rather a pipeline automation tool. IaC involves managing and modifying resources over time, which contrasts with Dagger's focused, one-directional graph structure that executes tasks sequentially without ongoing management. The interplay between Dagger and IaC tools like Terraform and Pulumi highlights their complementary nature, as Dagger can incorporate these technologies for provisioning but does not aim to replace their functionalities. This distinction allows teams to leverage both Dagger's efficient pipeline capabilities and IaC's management strengths in their software development lifecycle.
Solomon Hykes is the co-founder of Dagger. He is probably best known as the creator of Docker. The tool that changed how developers package, run and distribute software in the last 11 years. His impact on our industry is undeniable. Today, we discuss his new venture, Dagger. Dagger is a new approach to how we do CI/CD.
