How GitHub uses eBPF to improve deployment safety
Learn how Github uses eBPF to detect and prevent circular dependencies in its deployment tooling.
Did you know that, at GitHub, we host all of our own source code on github.com? We do this because we’re our own biggest customer—testing out changes internally before they go to users. However, there’s one downside: If github.com were ever to go down,...
GitHub's use of eBPF to prevent circular dependencies in deployment tooling is a compelling example of how low-level kernel instrumentation can solve high-level operational challenges. The strongest aspect of this narrative is its technical transparency: GitHub openly shares the problem, the constraints (e.g., stateful hosts serving production traffic), and the solution's evolution. The approach leverages eBPF's flexibility to intercept network calls and DNS queries without disrupting production...
