The user-authn module: Custom Resources

DexAuthenticator

Scope: Namespaced

After the DexAuthenticator object appears in the namespace, the following objects will be created:

Deployment containing oauth2-proxy and redis containers
Service, pointing to a Deployment with an oauth2-proxy
Ingress, configured to receive requests on https://<applicationDomain>/dex-authenticator and send it to a service side
Secrets, needed to access Dex

NOTE! After restarting a pod with an oauth2-proxy, the current access token and id token will be queried (using the refresh token) and stored in a redis memory.

Example:

apiVersion: deckhouse.io/v1
kind: DexAuthenticator
metadata:
  name: app-name
  namespace: app-namespace
spec:
  applicationDomain: app-name.kube.my-domain.com
  sendAuthorizationHeader: false
  applicationIngressCertificateSecretName: ingress-tls
  applicationIngressClassName: nginx
  keepUsersLoggedInFor: 720h
  allowedGroups:
  - everyone

  whitelistSourceRanges:
  - 1.1.1.1/32
  - 192.168.0.0/24

spec
object
Required value
- spec.allowedGroups
  array of strings
  Groups that the user should be in to authenticate successfully.
  
  Additionally, this parameter limits the list of groups that will be put into OIDC token (there will be an intersection of the specified groups and the actual groups of the user).
  
  Default: All groups are allowed.
- spec.applicationDomain
  string
  Required value
  Public domain that points to your application. Must be specified without HTTP scheme.
  
  Pattern: ^[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*$
  Example:
  applicationDomain: my-app.domain.com
- spec.applicationIngressCertificateSecretName
  string
  Name of TLS-certificate secret specified in your application Ingress object to add to Dex authenticator Ingress object for HTTPS access. Secret must be located in the same namespace with DexAuthenticator object.
  
  Pattern: ^(|[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*)$
  Example:
  applicationIngressCertificateSecretName: ingress-tls
- spec.applicationIngressClassName
  string
  Required value
  Ingress class that serves your application ingress resource.
  
  Pattern: ^[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*$
  Example:
  applicationIngressClassName: nginx

- spec.nodeSelector
  object
  If specified, the dex-authenticator pods nodeSelector.
  
  If the parameter is omitted or false, it will be determined automatically.
  
  Pattern: the same as in the pods’ spec.nodeSelector parameter in Kubernetes;

  boolean
  Request to application will be sent with “Authorization: Bearer” header when the option is switched to true.
- spec.signOutURL
  string
  Provide the URL from which requests will be proxied to the Dex authenticator sign out URL.
- spec.tolerations
  array of objects
  If specified, the dex-authenticator pods tolerations.
  
  The dex-authenticator pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator .
  
  If the parameter is omitted or false, it will be determined automatically.
  
  Pattern: Standard toleration object. Pods inherit this object AS IS.
  - spec.tolerations.effect
    string
    Effect indicates the taint effect to match. Empty means match all taint effects.

    Allowed values: Exists, Equal
  - spec.tolerations.tolerationSeconds
    integer
    TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint.

  - spec.tolerations.value
    string
    Value is the taint value the toleration matches to.
    
    If the operator is Exists, the value should be empty, otherwise just a regular string.

  Example:
  whitelistSourceRanges: 192.168.42.0/24
