• Adjustments to the NGINX fork

Our NGINX fork

Our fork of the NGINX chart was pulled from GitHub.

Adjustments to the NGINX fork

The following adjustments were made to the NGINX fork:

• tcp-configmap.yaml: is optional depending on new tcpExternalConfig setting
• Ability to use a templated TCP ConfigMap name from another chart
  • controller-configmap-tcp.yaml: .metadata.name is a template ingress-nginx.tcp-configmap
  • controller-deployment.yaml: .spec.template.spec.containers[0].args uses ingress-nginx.tcp-configmap template for ConfigMap name
  • GitLab chart overrides ingress-nginx.tcp-configmap so that gitlab/gitlab-org/charts/gitlab-shell can configure its TCP service
• Ability to use a templated Ingress name based on the release name
• Replace controller.service.loadBalancerIP with externalIpTpl (defaults to global.hosts.externalIP )
• Added support to add common labels through common.labels configuration option
• controller-deployment.yaml:
  • Add podlabels and global.pod.labels to .spec.template.metadata.labels
• default-backend-deployment.yaml:
  • Add podlabels and global.pod.labels to .spec.template.metadata.labels
• Disable NGINX’s default nodeSelectors.
• Added support for PDB maxUnavailable.
• Remove NGINX’s isControllerTagValid helper in charts/nginx-ingress/templates/_helpers.tpl
  • The check had not been updated since it was implemented in 2020.
  • As part of #3383, we need to refer to a tag that will contain ubi, meaning that the semverCompare would not work as expected anyway.
• Added support for autoscaling/v2beta2 and autoscaling/v2 APIs in HPAs and extended HPA settings to support memory and custom metrics, as well as behavior configuration.
• Added conditional support for API version of PodDisruptionBudget.
• Add the following booleans to enable/disable GitLab Shell (SSH access) independently for the external and internal (if enabled with controller.service.internal.enabled) services:
  • controller.service.enableShell.
  • controller.service.internal.enableShell. (follows the exisiting chart pattern of controller.service.enableHttp(s))
• Add the template call {{ include "ingress-nginx.automountServiceAccountToken" . }} to controller-serviceaccount.yaml

• Add the template to _helpers.tpl:

  {{/*
  Set if the default ServiceAccount token should be mounted by Kubernetes or not.
  
  Default is 'true'
  */}}
  {{- define "ingress-nginx.automountServiceAccountToken" -}}
  automountServiceAccountToken: {{ pluck "automountServiceAccountToken" .Values.serviceAccount .Values.global.serviceAccount | first }}
  {{- end -}}
  

• Add the template call {{ include "ingress-nginx.defaultBackend.automountServiceAccountToken" . }} to default-backend-serviceaccount.yaml

• Add the template to _helpers.tpl:

  {{/*
  Set if the default ServiceAccount token should be mounted by Kubernetes or not.
  
  Default is 'true'
  */}}
  {{- define "ingress-nginx.defaultBackend.automountServiceAccountToken" -}}
  automountServiceAccountToken: {{ pluck "automountServiceAccountToken" .Values.defaultBackend.serviceAccount .Values.global.serviceAccount | first }}
  {{- end -}}
  

• Add the following attributes to comply with Pod Security Standards Profile Restricted:
  • controller-deployment.yaml
    • spec.template.spec.containers[0].securityContext.runAsNonRoot
    • spec.template.spec.containers[0].securityContext.seccompProfile
