NGINX

Overview#

We built a customized NGINX image, based on the official open source version and containing a consul-template and an NGINX server, to satisfy the following requirements:

  • Dynamically updating the upstream directive to point to available oxAuth/oxTrust/oxShibboleth/oxPassport containers
  • Restarting the NGINX process when its configuration is changed (without restarting the container)

Note the following points: - This container relies on Consul - Kubernetes deployment can omit this container and use NGINX Ingress instead

Version#

The latest stable version for Gluu Server Docker Edition v3.1.6 is gluufederation/nginx:3.1.6_02.

Environment Variables#

The following environment variables are supported by the container:

  • GLUU_CONFIG_ADAPTER: The config backend adapter, can be consul (default) or kubernetes.
  • GLUU_CONFIG_CONSUL_HOST: hostname or IP of Consul (default to localhost).
  • GLUU_CONFIG_CONSUL_PORT: port of Consul (default to 8500).
  • GLUU_CONFIG_CONSUL_CONSISTENCY: Consul consistency mode (choose one of default, consistent, or stale). Default to stale mode.
  • GLUU_CONFIG_CONSUL_SCHEME: supported Consul scheme (http or https).
  • GLUU_CONFIG_CONSUL_VERIFY: whether to verify cert or not (default to false).
  • GLUU_CONFIG_CONSUL_CACERT_FILE: path to Consul CA cert file (default to /etc/certs/consul_ca.crt). This file will be used if it exists and GLUU_CONFIG_CONSUL_VERIFY set to true.
  • GLUU_CONFIG_CONSUL_CERT_FILE: path to Consul cert file (default to /etc/certs/consul_client.crt).
  • GLUU_CONFIG_CONSUL_KEY_FILE: path to Consul key file (default to /etc/certs/consul_client.key).

  • GLUU_CONFIG_KUBERNETES_CONFIGMAP: Kubernetes configmaps name (default to gluu).
  • GLUU_CONFIG_KUBERNETES_USE_KUBE_CONFIG: Load credentials from $HOME/.kube/config, only useful for non-container environment (default to false).
  • GLUU_SECRET_ADAPTER: The secrets adapter, can be vault or kubernetes.
  • GLUU_SECRET_VAULT_SCHEME: supported Vault scheme (http or https).
  • GLUU_SECRET_VAULT_HOST: hostname or IP of Vault (default to localhost).
  • GLUU_SECRET_VAULT_PORT: port of Vault (default to 8200).
  • GLUU_SECRET_VAULT_VERIFY: whether to verify cert or not (default to false).

  • GLUU_SECRET_VAULT_CACERT_FILE: path to Vault CA cert file (default to /etc/certs/vault_ca.crt). This file will be used if it exists and GLUU_SECRET_VAULT_VERIFY set to true.
  • GLUU_SECRET_KUBERNETES_NAMESPACE: Kubernetes namespace (default to default).
  • GLUU_SECRET_KUBERNETES_CONFIGMAP: Kubernetes secrets name (default to gluu).
