Getting 404 after deploying the kv example

[pparshin]

Hi,
I've tried to deploy the KV example using your documentation but unfortunately getting the 404 Not Found error from Nginx. Could you please help me to find the problem?

Steps to reproduce:

1. Firstly I tried minikube, after that I installed kind and nginx ingress controller.

kind create cluster --config kind-config.yaml --image=kindest/node:v1.19.4

2. Installed the tarantool operator using your doc
3. Deployed the app

On step "Ensure cluster became operational" I don't see any status:

Hello!
It is not clear what exactly the 404 returns. Cluster is not available to you via http?
Can you execute port-forward to some Tarantool pod and get into the cartridge web-ui? (how to do this can be found at the end of this doc section).

It is not clear what exactly the 404 returns. Cluster is not available to you via http?

As I understand the ingress controller should route my requests to the app via 80 port

But this request returns 404:

curl -XPOST http://localhost/kv -d '{"key":"key_1", "value": "value_1"}'

Can you execute port-forward to some Tarantool pod and get into the cartridge web-ui? (how to do this can be found at the end of this doc section).

After doing this I got into the cartridge web ui by URL http://localhost:8081/admin/cluster/dashboard

Now I can put and get values

$ curl -XPOST http://localhost:8081/kv -d '{"key":"key_1", "value": "value_1"}'
{"info":"Successfully created"}

Thanks for the help. It seems quite unclear from the doc that you must do the port forwarding
