Docker Extensions: Using and Building Them
35:24 Share

Bret is joined by Guillaume Tardif and Felipe Cruz of Docker Inc. for a deep dive into Docker extensions.

Docker Extensions are a favorite new feature. Guillaume and Felipe are both engineers at Docker and they walk us through how extensions came about, how to install them, and how to submit them to the marketplace.

By the time Docker released extensions at DockerCon in May 2022, there were already a dozen solid extensions, including a disk manager, log explorer, and other third-party tools like Portainer, Snyk, and Anchor. Docker extensions will be most helpful to people who use Docker Desktop.

Streamed live on YouTube on June 16, 2022.
