Hi, I need to port forward a service inside the flyte sandbox container. I was able to do this by launching the container as where the service is running at 127.0.0.1:8501.

docker create --privileged -p 0.0.0.0:30082:30082 -p 0.0.0.0:30084:30084 -p 0.0.0.0:30086:30086 -p 0.0.0.0:30088:30088 -p 0.0.0.0:30089:30089 -p 0.0.0.0:30080:30080 -p 0.0.0.0:30081:30081 -p 127.0.0.1:8501:8501 --env SANDBOX=1 --env KUBERNETES_API_PORT=30086 --env FLYTE_HOST=localhost:30081 --env FLYTE_AWS_ENDPOINT=<http://localhost:30084> --mount type=bind,source=/home/aswanth/.flyte,target=/etc/rancher/ --mount type=bind,source=/home/aswanth/.flyte/state,target=/srv/flyte --name flyte-sandbox <http://cr.flyte.org/flyteorg/flyte-sandbox:dind-f69fb09ca189e8bf57e1a6a12db168274f640d15|cr.flyte.org/flyteorg/flyte-sandbox:dind-f69fb09ca189e8bf57e1a6a12db168274f640d15>

after this when i try to register my workflows using pyflyte register i am gettting the following error

grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:

status = StatusCode.UNAVAILABLE

details = "failed to connect to all addresses; last error: UNAVAILABLE: Socket closed"

debug_error_string = "UNKNOWN:Failed to pick subchannel {created_time:"2023-02-20T12:41:31.69117013+05:30", children:[UNKNOWN:failed to connect to all addresses; last error: UNAVAILABLE: Socket closed {created_time:"2023-02-20T12:41:31.691159352+05:30", grpc_status:14}]}"

how can i achieve my intention? Thanks in advance

could you show your flytectl config

Hi @Aswanth Krishnan Also, what we call "port forward" is basically a temporary version of what a

NodePort

service would do. To expose a Pod using a specific pair of ports, you could do it imperatively using `kubectl expose`: https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#expose

@Kevin Su this is my flytectl config

admin:
  # For GRPC endpoints you might want to use dns:///flyte.myexample.com
  endpoint: localhost:30080
  authType: Pkce
  insecure: true
console:
  endpoint: <http://localhost:30081>
logger:
  show-source: true
  level: 0

@Aswanth Krishnan your question makes a lot of sense!

kubectl port forward

will work while your terminal session is open,

kubectl expose

will create a Service for you to make it persistent

Okay thanks a lot! Do you think this will solve the issue I am facing while registering my workflows?

well, it should help 🙂 To register, are you using

pyflyte run

?

I am using pyflyte register

Were you able to resolve the issue?
