opened 08:59AM - 02 Jun 22 UTC

Hello, This is HS Jeong from South Korea. SW engineer. I went through the bo…ok and got stucked on ch 10. I found your repo and tried to test your code for ch 10 but failed Could you give me any guide? ## My situation 1. Windows WSL2 - Ubunto 20.04 2. Changed git head to `690314c` - your ch10 complete commit 3. Did all the way to `helm install proglog deploy/proglog` and checked all three pods running okay using `$ kubectl get pods` 4. port-forwarding and run `cmd/getservers/main.go` - but failed. ## Terminal output ```bash $ go run cmd/getservers/main.go 2022/06/02 17:49:28 rpc error: code = Unavailable desc = connection closed before server preface received exit status 1 ``` ```bash $ kubectl port-forward pod/proglog-0 8400 Forwarding from 127.0.0.1:8400 -> 8400 Forwarding from [::1]:8400 -> 8400 Handling connection for 8400 E0602 17:49:28.379357 10869 portforward.go:406] an error occurred forwarding 8400 -> 8400: error forwarding port 8400 to pod d871ac34568f6a8d9a87107d4ecca4fb5fd1c4988110266b83a70e42cd1645a6, uid : failed to execute portforward in network namespace "/var/run/netns/cni-00ea3bcd-7544-2ddc-97d0-4414947404b1": failed to connect to localhost:8400 inside namespace "d871ac34568f6a8d9a87107d4ecca4fb5fd1c4988110266b83a70e42cd1645a6", IPv4: dial tcp4 127.0.0.1:8400: connect: connection refused IPv6 dial tcp6 [::1]:8400: connect: connection refused E0602 17:49:28.379731 10869 portforward.go:234] lost connection to pod ```
