hi, i deployed flyte to my local k8s cluster, i can view the web ui, but can not use the command line to execute workflows, the following are is the error, any way to workaround,thank you!
g
did you set insecure in flytectl_config to false?
b
this is the config.yaml
g
try to add 
insecure_skip_verify: true
to admin config
b
@glamorous-carpet-83516 hi kevin, same error
@glamorous-carpet-83516 seems like the command line used https://flyte.nginxbeta.k8s, but actually it is http://flyte.nginxbeta.k8s
g
how did you install flyte? use helm install?
b
helm install
g
cc @average-finland-92144 did you run into this issue before?
wait, could you set insecure to true instead?
b
already set it true, still got the same error
a
hey @*盛毅* what chart did you install*?*
have you tried not specifying the port in 
endpoint
?
b
@average-finland-92144 hello David, i used the flyte-core helm chart and wanna test it in multi-cluster, the error message showed rpc request to a http server, how to config the endpoint to use http protocol,here are my config.yaml . Can you show me your config file???? thank you! 
admin:
# For GRPC endpoints you might want to use dns:///flyte.myexample.com
endpoint: dns:///flyte.nginxbeta.k8s
#endpoint: dns:///10.24.73.16:32332
authType: Pkce
insecure: true
#insecure_skip_verify: true
logger:
show-source: true
level: 0
a
sure, this is my config file:
Copy code
admin:
  # For GRPC endpoints you might want to use dns:///flyte.myexample.com
  endpoint: dns:///flyte-the-hard-way.uniondemo.run
  authType: Pkce
  insecure: false  
  insecureSkipVerify: true

logger:
  show-source: true
  level: 6
the 
http1.x
error message typically refers to a gRPC connection using the wrong port. What are you using for Ingress? can you share a 
describe
of that resource?

the nginx-ingress has a loadbalance IP 10.24.73.232 , but in the ing describe above it got the address 
Address:          10.24.73.21
i have no idea what happended . but i can successfully visit the flyte console web ui using the ip 10.24.73.232
@glamorous-carpet-83516 @average-finland-92144 got those errors after i enabled auth section in the helm chart, before that it is ok!

I don't see this annotation in your ingress resource

Aslo for auth, can you share your Helm values file?

in some cases, if redirects are not working (because there's some networking component in the middle preventing it), specifying the port in config helps, like: 
endpoint: dns:///flyte.nginxbeta.k8s:443
Also, for auth, please check out this guide (in review) to make sure it matches your deployment: https://flyte--3837.org.readthedocs.build/en/3837/deployment/configuration/auth_setup.html

@average-finland-92144 hi David, sorry to interrupt you again, this is what i got when using flytectl , i can visit the web ui ,cannot connect using cli, is it something wrong the nginx ingess???

@average-finland-92144 this is some info i got from https://discuss.flyte.org/t/10376700/hello-could-somebody-help-me-debug-connection-to-the-flyte-c , i deployed flyte on my local cluster, do i need to change a ingress controller???
a
Sorry for the delay That's 1/2 instances I've seen users having to switch from an nginx implementation due to gRPC issues. Some users running also on local K8s cluster, use Traefik or even MetaLB. Besides the ingress portion, for the PKCE flow to work properly with the 
flyte-core
chart implementation, there are three native clients that have to be configured. This is documented here
