`faas-flow-tower` not monitoring the flows

I am struggling to set up the faas-flow-tower utility.

Let's say what I tried... I tried setting up a simple flow-test function as follows:

flow-test.yml:

version: 1.0
provider:
  name: openfaas
  gateway: http://127.0.0.1:9999
functions:
  flow-test:
    lang: faas-flow
    handler: ./flow-test
    image: localhost:5000/flow-test:latest
    labels:
      faas-flow: 1
    annotations:
      faas-flow-desc: "test flow to greet"
    environment_file:
      - flow.yml
    secrets:
      - s3-secret-key
      - s3-access-key

flow.yml:

environment:
  gateway: "gateway.openfaas:8080" # The address of OpenFaaS gateway
  enable_tracing: true # tracing allows to monitor requests
  trace_server: "jaeger-agent.faasflow:5775" # The address of jaeger tracing agent
  consul_url: "consul.faasflow:8500" # The address of consul
  s3_url: "minio.faasflow:9000" # The address of minio

flow-test/handler.go:

package function

import (
    faasflow "github.com/faasflow/lib/openfaas"
)

// Define provide definition of the workflow
func Define(flow *faasflow.Workflow, context *faasflow.Context) (err error) {
    flow.SyncNode().Modify(func(data []byte) ([]byte, error) {
        result := "Hello " + string(data)
        return []byte(result), nil
    })
    return nil
}

// OverrideStateStore provides the override of the default StateStore
func OverrideStateStore() (faasflow.StateStore, error) {
    // NOTE: By default FaaS-Flow use consul as a state-store,
    //       This can be overridden with other synchronous KV store (e.g. ETCD)
    return nil, nil
}

// OverrideDataStore provides the override of the default DataStore
func OverrideDataStore() (faasflow.DataStore, error) {
    // NOTE: By default FaaS-Flow use minio as a data-store,
    //       This can be overridden with other synchronous KV store
    return nil, nil
}

$ faas-cli up -f flow-test.yml

Hello Abhishek

So far so good.

The problem happens when I try to use faas-flow-tower.

faas-flow-tower/conf.yml:

  environment:
  basic_auth: true
  gateway_public_uri: "http://localhost:9999"
  gateway_url: "http://gateway.openfaas:8080/"
  secret_mount_path: "/var/openfaas/secrets"
  trace_url: "http://jaeger-query.faasflow:16686/"

In the above file I made change to the gateway_public_uri

faas-flow-tower/stack.yml:

provider:
  name: openfaas
  gateway: http://127.0.0.1:9999

functions:
  # dashboard
  faas-flow-dashboard:
    lang: dockerfile
    handler: ./dashboard
    image: localhost:5000/faas-flow-dashboard:3.0.8
    environment:
      read_debug: true
      write_debug: true
      combine_output: false
    environment_file:
      - conf.yml
    secrets:
      - basic-auth
    labels:
      com.openfaas.scale.zero: "false"

  # list flow functions deployed in openfaas
  list-flow-functions:
    lang: go
    handler: ./list-flow-functions
    image: localhost:5000/list-flow-functions:1.0.1
    environment:
      read_debug: true
      write_debug: true
      combine_output: false
    environment_file:
      - conf.yml
    secrets:
      - basic-auth
    labels:
      com.openfaas.scale.zero: "false"

  # Generate dot graph for faas-flow
  dot-generator:
    lang: go
    handler: ./dot-generator
    image: localhost:5000/dot-generator:1.2.0
    environment_file:
      - conf.yml
    environment:
      read_timeout: 120
      read_debug: true
      write_timeout: 120
      write_debug: true
      combine_output: false
    labels:
      com.openfaas.scale.zero: "false"

  # Collect metrics for faas-flow
  metrics:
    lang: go
    handler: ./metrics
    image: localhost:5000/metrics:1.6.0
    environment_file:
      - conf.yml
    environment:
      read_debug: true
      read_timeout: 120
      write_timeout: 120
      write_debug: true
      combine_output: false
    labels:
      com.openfaas.scale.zero: "false"

Under faas-flow-dashboard I just changed lang: Dockerfile to lang: dockerfile, and added the image local to be saved in local registry.

Before deploying I created a basic-auth secret as follows (I doubt this basic-auth step which I did):

kubectl create secret generic basic-auth --from-literal=username=abhishek --from-literal=password=abhishek --namespace openfaas-fn

And then I deploy faas-flow-tower as:

$ faas-cli up -g http://127.0.0.1:9999

faas-flow-tower does not monitor anything. Where I am going wrong in my setup? Please can anyone help me?
