Escape From Your VMs with Image2Docker

(But we have a solution)

We have a problem

Should we solve it like this?

Lift-and-shift has its own problems• Wouldn’t learning Docker be easier?• Container best practices?• What are the use-cases?

• Targeted• Open source• Extensible

Image2Docker

Lift-and-shift is hardTooling• Security – are there secrets in the VM?• Content – do we need to lift *everything*?• Config explosion – how many init systems?• Validation – can we automate the testing?
