At DockerCon, one of Docker’s major pushing was modernizing traditional applications, MTA. They’re specifically targeting containerizing legacy Windows applications, a lift and shift approach by placing an entire Windows image inside a container. Edward Haletky isn’t entirely won over by the draft specifications as outlined by Docker for this process. He does like that Docker introduced certified containers, which goes a long way to alleviate security concerns, and credential specification within PowerShell. The big challenge he sees is identifying applications going forward.
