Tech references to understand linkerd internals

[mrveera]

Anyone here have reference to understand internals of linkerd2 other than code, We are having too many 503s
When we make call from service A to B, we know that call reaches outbound proxy of service A but it doesn't go to service B inbound proxy
I am new to Rust so looking for tech docs if we have any
or any debugging tricks ?

Hey @veera83372

I'll link below some of my favourite pieces written/shot by the maintaining team :)

• For 502s
• Inside linkerd2-proxy
• Using the debugging sidecar
• Deep dive (kubecon pres)
• Nondestructive forensics - debugging k8s services (kubecon pres on how to use linkerd to debug)

Think if you have a look at these you'll get a better feel for how to debug everything. There are a few tools e.g tap that can make your life a bit easier.

Hope this helps : )
