I want to access the memgraph k8s service from outside
I tried with a LoadBalancer and then with NodePort, but didn’t succeed:

LoadBalancer:

(base) raphy@raohy:~/.talos/memgraph$ helm upgrade --install memgraph-024 memgraph/
memgraph --set service.type=LoadBalancer

(base) raphy@raohy:~$ kubectl get svc memgraph-024
NAME           TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
memgraph-024   LoadBalancer   aa.aaa.aaa.aa   cc.c.cc.c     7687:31159/TCP   4h50m

Trying to connect to the memgraph-024 service I get “couldn’t connect to the host” :

(base) raphy@raohy:~$ mgconsole --host cc.c.cc.c --port 7687 --use-ssl=false
Connection failure: couldn't connect to host: Connection timed out

I then added the actual the control-plane node’s IP as External-IP :

(base) raphy@raohy:~/.talos/memgraph$ kubectl patch svc memgraph-024 -p '{"spec":
{"externalIPs":["bbb.bbb.bbb.bbb"]}}
service/memgraph-024 patched

(base) raphy@raohy:~/.talos/memgraph$ kubectl get svc memgraph-024
NAME           TYPE           CLUSTER-IP      EXTERNAL-IP                 PORT(S)              AGE
memgraph-024   LoadBalancer   aa.aaa.aaa.aa   cc.c.cc.c,bbb.bbb.bbb.bbb   7687:31159/TCP   6h14m

I get “couldn’t connect to the host” :

(base) raphy@raohy:~$ mgconsole --host cc.c.cc.c --port 7687 --use-ssl=false
Connection failure: couldn't connect to host: Connection timed out

(base) raphy@raohy:~$ mgconsole --host bbb.bbb.bbb.bbb --port 7687 --use-ssl=false
Connection failure: couldn't connect to host: Connection refused

NodePort:

(base) raphy@raohy:~/.talos/memgraph$ helm upgrade --install memgraph-024 memgraph/
memgraph --set service.type=NodePort

(base) raphy@raohy:~/.talos/memgraph$ kubectl get svc memgraph-024
NAME           TYPE       CLUSTER-IP      EXTERNAL-IP       PORT(S)          AGE
memgraph-024   NodePort   aa.aaa.aaa.aa   bbb.bbb.bbb.bbb   7687:31159/TCP   6h25m

I get “couldn’t connect to the host” :

(base) raphy@raohy:~/.talos/memgraph$ mgconsole --host bbb.bbb.bbb.bbb --port 7687 --
use-ssl=false
Connection failure: couldn't connect to host: Connection refused


(base) raphy@raohy:~/.talos/memgraph$ mgconsole --host aa.aaa.aaa.aa --port 7687 --use-
ssl=false
Connection failure: couldn't connect to host: Connection timed out

What am I missing and/or doing wrong? How to externally connect to the kubernetes memgraph service?
