Why do you need this?

I am using OpenFaaS for my course project for my project at University of Michigan. I am trying to study the utilization of GPUs in serverless applications.

Who is this for?

This is for me. I am a student at University of Michigan.

What company is this for? Are you listed in the ADOPTERS.md file?

Expected Behaviour

Unable to login, what credentials do I give in the cli?
Do I give my node username and password?

Current Behaviour

Calling the OpenFaaS server to validate the credentials...
Cannot connect to OpenFaaS on URL: http://127.0.0.1:8080. Get "http://127.0.0.1:8080/system/functions": dial tcp 127.0.0.1:8080: connect: connection refused

-- I have tried using all the ways giving multiple gateways and using the environment variable too prat@node-0:~$ cat faas_password.txt | faas-cli login --username prat --password-stdin --gateway $OPENFAAS_URL

Steps to Reproduce (for bugs)

Context

Your Environment

• FaaS-CLI version ( Full output from: faas-cli version ):

• CLI:
  commit: a3e72b5881c4efcc7a366a2e8dc384399c807dfc
  version: 0.16.23
  I am currently using a remote node in Cloudlab. I have written my function in python3 and all setup is done. But when I login there is an issue coming up

• Docker version docker version (e.g. Docker 17.0.05 ):

• Docker version 25.0.4, build 1a576c5

• Are you using OpenFaaS on Kubernetes or faasd?

• I have installed minikube and started my cluster on the node. I am using a remote node in cloud lab

• Operating System and version (e.g. Linux, Windows, MacOS):

• Linux Ubuntu 22.04.2 LTS

• Code example or link to GitHub repo or gist to reproduce problem:

• Other diagnostic information / logs from troubleshooting guide

Provided the file you’re cat-ing contains the appropriate password then you might try admin as the username:

https://docs.openfaas.com/deployment/kubernetes/#install-openfaas-community-edition-ce-via-arkade-or-helm

If you're using faasd then there's a book that would likely help:

cat faas_password.txt | faas-cli login --username admin --password-stdin --gateway https://127.0.0.1:8080
Calling the OpenFaaS server to validate the credentials...
Cannot connect to OpenFaaS on URL: https://127.0.0.1:8080. Get "https://127.0.0.1:8080/system/functions": dial tcp 127.0.0.1:8080: connect: connection refused
I tried with admin and password as admin as well, still got the connection refused

Is it better to install via arkade as I am using a remote node?
After the installation you'll receive a command to retrieve your OpenFaaS URL and password.
Does this statement mean arkade will set my credentials?

If you're using a remote node then 127.0.0.1 isn't usually going to be correct. You will need to specify the gateway in the login command, or set the CLI env var for the gateway.

I'm not sure why you are guessing the password. You are provided with the password for the gateway when you install, or if you're using k8s then you can retrieve it as per the command in the documentation.

This kind of conversation demonstrates why the template exists. It's really difficult for someone else to help when information drips into an issue.
