Overview

static UT codecov

The netns-rs crate provides an ultra-simple interface for handling network namespaces in Rust. Changing namespaces requires elevated privileges, so in most cases this code needs to be run as root.

This crate only supports linux kernel.

Build

cargo build

Test(as root)

CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUNNER="sudo -E" cargo test

or

sudo -E cargo test

Credits

The main resource so far has been the source code of netns(golang), CNI network plugins and iproute2.

Altnernatives

https://github.com/little-dude/netlink: rtnetlink/src/ns.rs provides the same functionality, but its creation of netns in a new process feels a bit heavy.

    Refactor to remove netns.

    When netns is deleted, the NetNs instance will no longer be available and we should use the self argument in the remove function in order to consume the NetNs instance.
