Network Policy visualization — overlaying allow/deny rules on the topology graph

[nadaverell]

An idea we've been thinking about: overlaying active NetworkPolicy rules directly onto the topology graph.

The core use case is answering "why can't Service A talk to Service B?" without having to read through YAML selectors. Concretely, this could look like:

• Green edges for explicitly allowed paths
• Red/dashed edges where traffic is blocked by policy
• A "locked" indicator on pods that are fully isolated

Nothing planned or scoped yet — curious whether this is a pain point for people and what form would actually be useful. Do you reach for a separate tool for this today? Would an overlay on the existing topology be the right UI, or a dedicated view?

An editor with visualization like https://editor.networkpolicy.io/ — where we can edit via a GUI and apply changes in the same tab — would be nice.

Shipped — Topology now has a Policies toggle that overlays NetworkPolicy effects onto edges. Edges render as allowed / blocked / unprotected per pod based on matching NetworkPolicy rules.

Not yet: a "locked" indicator on fully isolated pods, or green/red color semantics per the original sketch. The toggle today surfaces the data; the visual language can evolve.

Closing for now.
