Getting Started with Ephemeral Containers
AFAIK this is available in 1.23 already. There are several tools already out that support this including https://github.com/lightrun-platform/koolkits/ and quite a few others.

Interview with Tom Granot - Developer Observability, KoolKits and Reliability
Thatās when Leonid, our CTO, came up with the idea of KoolKits - which is an opinionated set of pre-installed tools for kubectl debug. Thereās a variant for each language/platform, e.g. Java (JVM), NodeJS, Python and even Go. Weāre pretty excited about it and recently open-sourced it as well - see the project here.

KoolKits (Kubernetes toolkits) are highly-opinionated, language-specific, batteries-included debug container images for Kubernetes!
It's a pretty simple idea - we LOVE kubectl debug, which allows you to spin up so-called ephemeral containers for debugging purposes in Kubernetes. One key thing that we wished we had in kdebug is great default container images - ones that contain all the tooling we know and love from debugging locally. Enter KoolKits!

KoolKits: Opinionated, language-specific, batteries-included debug container images for Kubernetes
My colleague Tom Granot created KoolKits. An open source project that makes it much easier to debug K8S images.

Taming the dragon: using llnode to debug your Node.js application
The result shows us that there's an array holding a lot (156027) of objects, and is probably the reason we have so many Visit objects in memory (spoiler: it is, look at line 13 and 16 of our server). Unfortunately, llnode can't tell where this array is located yet, but there's an open issue to add this feature in the future.
