Cory Snider f9c68e5fbc libn: fix resolver restore w/ chatty 'iptables -C'
Resolver.setupIPTable() checks whether it needs to flush or create the
user chains used for NATing container DNS requests by testing for the
existence of the rules which jump to said user chains. Unfortunately it
does so using the IPTable.RawCombinedOutputNative() method, which
returns a non-nil error if the iptables command returns any output even
if the command exits with a zero status code. While that is fine with
iptables-legacy as it prints no output if the rule exists, iptables-nft
v1.8.7 prints some information about the rule. Consequently,
Resolver.setupIPTable() would incorrectly think that the rule does not
exist during container restore and attempt to create it. This happened
work work by coincidence before 8f5a9a741b
because the failure to create the already-existing table would be
ignored and the new NAT rules would be inserted before the stale rules
left in the table from when the container was last started/restored. Now
that failing to create the table is treated as a fatal error, the
incompatibility with iptables-nft is no longer hidden.

Switch to using IPTable.ExistsNative() to test for the existence of the
jump rules as it correctly only checks the iptables command's exit
status without regard for whether it outputs anything.

The Moby Project

Moby Project logo

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 systems, 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.
