Can't find access log

[yannrenarddav]

Hi,

We have an application complaining about lost request. I can see the request on the external load balancer, now I would like to check on contour/envoy if everything is OK. Reading the documentation I can see that it's native but I don't see anything on logs, or I don't look at the right place. Can you help me to find the logs please ?

$ kubectl get httpproxy -A
NAMESPACE NAME FQDN TLS SECRET STATUS STATUS DESCRIPTION
test hello test.k8s-stg.c2.dav.fr valid Valid HTTPProxy

-> I would like to trace connections to that (it's a test cluster but I have exacly the same thing in production with a real app).

$ kubectl logs -l app=envoy -n projectcontour

I'm using k8s 1.24.14 and contour v1.23.6 with the default configuration (https://raw.githubusercontent.com/projectcontour/contour/release-1.23/examples/render/contour.yaml), I just changed that :
$ sdiff -s contour-v1.23.6.yml contour-v1.23.6.yml.ori

The access logs are in envoy container of the envoy pod. Did you try kubectl logs -l app=envoy -n projectcontour -c envoy?

No I didn't try that, thank you it's better ! 👍
