@agardnerIT are all pods running?

I've turned some off (like OpenSearch, Jaeger, Grafana and accounting service because it keeps crashing) but other than that, yes they are.

@puckpuck any ideas here?
I'm starting to suspect of the PR #1785.

Have you redeployed your running demo in K8s after that was merged?

Sorry @agardnerIT, this question was for @puckpuck 😅 .
He has the demo running also using Helm.

Locally, we have one issue with accountingservice, but yours is new.

Side note: It would be good to document which services can be disabled and what effects (if any) that has on the core demo / usecases.

For example, I've turned off my accounting service - but I have no idea whether that matters to the "core system" or not.

Perhaps a new column / table on this page like:

service core service technology
accountingservice ✅ .NET
grafana 🔴 ...

Note: Turning off core services may effect the demo system. Non-core services are "safe" to disable and cause minimal disruption to the core usecases for the demo.

I (probably) have the same problem, but not with Kubernetes, but with local docker.

When I open http://localhost:8080 I get this:
upstream connect error or disconnect/reset before headers. reset reason: connection timeout

http://localhost:8080/jaeger/ui works fine, http://localhost:8080/feature/ works fine as well.
http://localhost:8080/grafana does not work
And the normal shop does not work.

Next to the standard setup, I have https://github.com/cbos/observability-toolkit coupled with the demo setup.
In the logging in Loki I see this:

2024-11-29 14:06:28.036 | [2024-11-29T13:06:28.036Z] "POST /api/checkout HTTP/1.1" 503 UF upstream_reset_before_response_started{connection_timeout} - "-" 385 91 4999 - "-" "python-requests/2.31.0" "4f9ddd89-e990-9549-9c85-77562419236d" "frontend-proxy:8080" "52.140.110.196:8080" frontend - 172.22.0.26:8080 172.22.0.25:44032 - -

This is a weird ip address where it tries to connect to: 52.140.110.196

This is what I have in the Envoy proxy (http://localhost:10000/clusters):

Some of the IP addresses are not resolved to local addresses, but remote/public addresses.

Changing src/frontendproxy/Dockerfile fixed my problem.
I changed the FROM to envoyproxy/envoy:v1.31-latest

#1768 changed this version from 1.30 to 1.32. cc: @puckpuck
The release notes of Envoy proxy mention something about internal_address_config.
https://www.envoyproxy.io/docs/envoy/v1.32.0/version_history/v1.32/v1.32.0.html

I don't know all details, but at least this fixed my problem, my frontend (and other services) are now resolved to local addresses:

@agardnerIT and @cbos in what distro of k8s are you running this?

I've tried out today with a local minikube and everything started fine 🤔
