Previously, we only printed a warning if a storage driver was deprecated. The
intent was to continue supporting these drivers, to allow users to migrate
to a different storage driver.
This patch changes the behavior; if the user has no storage driver specified
in the daemon configuration (so if we try to detect the previous storage
driver based on what's present in /var/lib/docker), we now produce an error,
informing the user that the storage driver is deprecated (and to be removed),
as well as instructing them to change the daemon configuration to explicitly
select the storage driver (to allow them to migrate).
This should make the deprecation more visible; this will be disruptive, but
it's better to have the failure happening *now* (while the drivers are still
there), than for users to discover the storage driver is no longer there
(which would require them to *downgrade* the daemon in order to migrate
to a different driver).
With this change, `docker info` includes a link in the warnings that:
/ # docker info

WARNING: The overlay storage-driver is deprecated, and will be removed in a future release.

When starting the daemon without a storage driver configured explicitly, but
previous state was using a deprecated driver, the error is both logged and
printed:

The Moby Project
Moby is an open-source project created by Docker to enable and accelerate software containerization.
It provides a "Lego set" of toolkit components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts and professionals to experiment and exchange ideas. Components include container build tools, a container registry, orchestration tools, a runtime and more, and these can be used as building blocks in conjunction with other tools and projects.
Principles
Moby is an open project guided by strong principles, aiming to be modular, flexible and without too strong an opinion on user experience. It is open to the community to help set its direction.
- Modular: the project includes lots of components that have well-defined functions and APIs that work together.
- Batteries included but swappable: Moby includes enough components to build fully featured container system, but its modular architecture ensures that most of the components can be swapped by different implementations.
- Usable security: Moby provides secure defaults without compromising usability.
- Developer focused: The APIs are intended to be functional and useful to build powerful tools. They are not necessarily intended as end user tools but as components aimed at developers. Documentation and UX is aimed at developers not end users.
Audience
The Moby Project is intended for engineers, integrators and enthusiasts looking to modify, hack, fix, experiment, invent and build systems based on containers. It is not for people looking for a commercially supported system, but for people who want to work and learn with open source code.
Relationship with Docker
The components and tools in the Moby Project are initially the open source components that Docker and the community have built for the Docker Project. New projects can be added if they fit with the community goals. Docker is committed to using Moby as the upstream for the Docker Product. However, other projects are also encouraged to use Moby as an upstream, and to reuse the components in diverse ways, and all these uses will be treated in the same way. External maintainers and contributors are welcomed.
The Moby project is not intended as a location for support or feature requests for Docker products, but as a place for contributors to work on open source code, fix bugs, and make the code more useful. The releases are supported by the maintainers, community and users, on a best efforts basis only, and are not intended for customers who want enterprise or commercial support; Docker EE is the appropriate product for these use cases.
