devmapper: ensure that UdevWait is called after calls to setCookie Recent changes to devmapper broke the implicit requirement that UdevWait be called after every call to task.setCookie. Failure to do so results in leaks of semaphores in the LVM code, eventually leading to semaphore exhaustion. Previously this was handled by calling UdevWait in a ubiquitous defer function. While there was initially some concern with deferring the UdevWait function would cause some amount of race possibiliy, the fact that we never return the cookie value or any value used to find it, makes that possibility seem unlikely, so lets go back to that method Signed-off-by: Neil Horman <nhorman@tuxdriver.com> (cherry picked from commit 23dcfec1404411489e23fb9b76fc7096db139d04) Signed-off-by: Victor Vieux <victorvieux@gmail.com>
Moby is an open-source project created by Docker to advance the software containerization movement. It provides a “Lego set” of dozens of components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts to experiment and exchange ideas.
At the core of Moby is a framework to assemble specialized container systems. It provides:
All Moby components are containers, so creating new components is as easy as building a new OCI-compatible container.
Moby is an open project guided by strong principles, but modular, flexible and without too strong an opinion on user experience, so it is open to the community to help set its direction. The guiding principles are:
With Moby, you should be able to describe all the components of your distributed application, from the high-level configuration files down to the kernel you would like to use and build and deploy it easily.
Moby uses containerd as the default container runtime.
Moby is recommended for anyone who wants to assemble a container-based system. This includes:
Moby is NOT recommended for:
Docker is transitioning all of its open source collaborations to the Moby project going forward. During the transition, all open source activity should continue as usual.
We are proposing the following list of changes:
