c.RWLayer: check for nil before use Since commit e9b9e4ace294230c6b8eb has landed, there is a chance that container.RWLayer is nil (due to some half-removed container). Let's check the pointer before use to avoid any potential nil pointer dereferences, resulting in a daemon crash. Note that even without the abovementioned commit, it's better to perform an extra check (even it's totally redundant) rather than to have a possibility of a daemon crash. In other words, better be safe than sorry. [v2: add a test case for daemon.getInspectData] [v3: add a check for container.Dead and a special error for the case] Fixes: e9b9e4ace294230c6b8eb Signed-off-by: Kir Kolyshkin <email@example.com> (cherry picked from commit 195893d38160c0893e326b8674e05ef6714aeaa4) Signed-off-by: Sebastiaan van Stijn <firstname.lastname@example.org> Signed-off-by: Kir Kolyshkin <email@example.com>
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.
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.
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.
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.
