We're trying to set up a gitlab instance on our VPC contained K8S cluster. Because we cannot use the certmanager (and because we have a number of services running already), we've disabled a few services. Below is our configuration which we apply via terraform.

global:
  hosts:
    domain: ${var.hosted_zone}
    https: false
    gitlab:
      name: gitlab.${var.hosted_zone}
      https: false
    registry:
      https: false
  ingress:
    tls:
      enabled: false
    configureCertmanager: false

certmanager:
  install: false
prometheus:
  install: false
nginx-ingress:
  enabled: false
postgresql.install: ${var.managed_postgres == true ? "false" : "true"}

registry:
  ingress:
    tls:
      enabled: false

Gitlab works, hence the DB connection, gitaly and unicorn work. However, autodevops is giving us trouble. Concretely, the registry is giving us TLS errors. We've tried to disable its TLS as well but haven't succeeded so far

WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get https://registry.dev.foo.com/v2/: remote error: tls: internal error

There are no logs on the registry pods unfortunately. How would one go about getting the registry to work?
