Name
kf env - Print information about an App's environment variables.
Synopsis
kf env APP_NAME [flags]
Description
The env command gets the names and values of developer managed
environment variables for an App.
Environment variables are evaluated in the following order with later values
overriding earlier ones with the same name:
Space (set by administrators)
App (set by developers)
System (set by Kf)
Environment variables containing variable substitution "$(...)" are
replaced at runtime by Kubernetes.
Kf provides the following runtime environment variables:
CF_INSTANCE_ADDR: The cluster-visible IP:PORT of the App instance.
CF_INSTANCE_GUID: The UUID of the App instance.
INSTANCE_GUID: Alias of CF_INSTANCE_GUID
CF_INSTANCE_INDEX: The index number of the App instance, this will ALWAYS be 0.
INSTANCE_INDEX: Alias of CF_INSTANCE_INDEX
CF_INSTANCE_IP: The cluster-visible IP of the App instance.
CF_INSTANCE_INTERNAL_IP: Alias of CF_INSTANCE_IP
VCAP_APP_HOST: Alias of CF_INSTANCE_IP
CF_INSTANCE_PORT: The cluster-visible port of the App instance. In Kf this is the same as PORT.
DATABASE_URL: The first URI found in a VCAP_SERVICES credential.
DISK_LIMIT: The maximum amount of disk storage in MB the App can use.
LANG: Required by buildpacks to ensure consistent script load order.
MEMORY_LIMIT: The maximum amount of memory in MB the App can consume.
PORT: The port the App should listen on for requests.
VCAP_APP_PORT: Alias of PORT
VCAP_APPLICATION: A JSON structure containing app metadata.
VCAP_SERVICES: A JSON structure specifying bound services.
