ContainerWait on remove: don't stuck on rm fail Currently, if a container removal has failed for some reason, any client waiting for removal (e.g. `docker run --rm`) is stuck, waiting for removal to succeed while it has failed already. For more details and the reproducer, please check https://github.com/moby/moby/issues/34945 This commit addresses that by allowing `ContainerWait()` with `container.WaitCondition == "removed"` argument to return an error in case of removal failure. The `ContainerWaitOKBody` stucture returned to a client is amended with a pointer to `struct Error`, containing an error message string, and the `Client.ContainerWait()` is modified to return the error, if any, to the client. Note that this feature is only available for API version >= 1.34. In order for the old clients to be unstuck, we just close the connection without writing anything -- this causes client's error. Now, docker-cli would need a separate commit to bump the API to 1.34 and to show an error returned, if any. [v2: recreate the waitRemove channel after closing] [v3: document; keep legacy behavior for older clients] [v4: convert Error from string to pointer to a struct] [v5: don't emulate old behavior, send empty response in error case] [v6: rename legacy* vars to include version suffix] Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.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.
