In March of 2019, I talked with Michael about the new "docker-app" experimental tool. This clip talks about why it exists, and how to use it. In April 2019 Docker released a beta of 19.03 that includes "docker-app" as a plugin to the standard docker CLI, as "docker app", but most other features of this tool stay the same. We also talk about the standard behind this tool, CNAB.
