first app shell tutorial fails in "zed permission check" step

[ensonic]

Okay, this is not an issue in the zed util. Also tried the go-lang version of the tutorial and get the same error in this step too.

t tries to connect to a second port:

kubectl port-forward deployment/dev-spicedb 50051:50051
# in the example "localhost:50051"
go run check.go
2022/11/17 12:51:41 failed to check permission: rpc error: code = Unavailable desc = last connection error: connection error: desc = "transport: Error while dialing dial tcp 192.168.9.1:50053: connect: connection refused"

notice the 192.168.9.1:50053. Checking the serivice shows: grpc:50051►0 dispatch:50053►0 so that's dispatch. Now alos kubectl port-forwarding it, does not help though (tried kubectl port-forward deployment/dev-spicedb 50051:50051 50053:50053)

I've tried running the same code from within the cluster, but run into the same problem.

go build -o app -ldflags "-X main.address=dev:50051" check.go
docker build -t spicedb_test .
docker save -o spicedb_test.tar spicedb_test
ctr -n=k8s.io image import spicedb_test.tar
kubectl run -i --tty spicedb-test --image=docker.io/library/spicedb_test:latest --restart=Never --image-pull-policy=Never

I've found the relevant code
https://github.com/authzed/spicedb/blob/5009a53ac4ecb2f57ef7f6d9ed2444d166a6fa1d/internal/services/v1/permissions.go#L36
but not where it connects to port 50053 yet.

The error around port 50053 indicates that the system is trying to dispatch to other nodes within the cluster, but is failing to do so. I suspect your cluster is misconfigured for dispatch. How are you deploying the nodes within Kub?

[ensonic]

I used the spicedb-operator according to the instructions from
https://docs.authzed.com/spicedb/operator
It is a single node cluster (minikube)

on discord it sound I should disable dispatch, but since
https://docs.authzed.com/spicedb/operator#flags does not link to the docs of the cli, I am still hunting down how the flag might be called.

[ensonic]

With some help from discord, I updated to 1.15.0 and still get the same error. Next we disabled dispatch in the config:

spec:
  config:
    datastoreEngine: memory
    image: authzed/spicedb:v1.15.0
    dispatchUpstreamAddr: ""

but still get the error.

See authzed/spicedb-operator#111

@ensonic I'd suggest closing this issue as it's not a problem specific to zed, but a problem with the operator.

[ensonic]

Makes sense.
