How to use nginx-ingress on self hosting kubernetes

Kubernetes: v1.11.2 (Rancher v2.0.8)

Linux: Ubuntu 16.04

Docker: v1.11.2

Gitlab: 11.2.1

I used this for the install:

helm upgrade --install gitlab gitlab/gitlab --timeout 900 \
  --set global.hosts.domain=domain.com \
  --set certmanager-issuer.email=mail@domain.com \
  --set gitlab.migrations.image.repository=registry.gitlab.com/gitlab-org/build/cng/gitlab-rails-ce \
  --set gitlab.sidekiq.image.repository=registry.gitlab.com/gitlab-org/build/cng/gitlab-sidekiq-ce \
  --set gitlab.unicorn.image.repository=registry.gitlab.com/gitlab-org/build/cng/gitlab-unicorn-ce \
  --set gitlab.unicorn.workhorse.image=registry.gitlab.com/gitlab-org/build/cng/gitlab-workhorse-ce \
  --set gitlab.task-runner.image.repository=registry.gitlab.com/gitlab-org/build/cng/gitlab-task-runner-ce \
  --namespace gitlab

No domain resolve to any service. When I use external nginx-ingress into deamonset deployment it's working great but I would like to use the one that gitlab provide.There's any option that I can use to make it working ?

Also, I dont figure out how to use ssh with gitlab because the node already use port 22 of ssh-server to communicate with others.
