From Docker to Dagger

This week we’re joined by Solomon Hykes, the creator of Docker. Now he’s back with his next big thing called Dagger — CI/CD as code that runs anywhere. We’re users of Dagger so check out our codebase if you want to see how it works. On today’s show Solomon takes us back to the days of Docker, what it was like on that 10 year journey, his transition from Docker to Dagger, Dagger’s community-led growth model, their focus on open source and community, how it works, and even a cameo from Kelsey Hightower to explain how Dagger works.
