Jina uses a number of environment variables to determine different behaviours. To see all supported environment variables and their current values, run
jina-vf
If you use containerized Executors (including Kubernetes and Docker Compose), you can pass separate environment variables to each Executor in the following way:
For more information about the environment variable syntax used in Jina YAML configurations, see here.
The following environment variables are used internally in Jina:
Environment variable
Description
JINA_AUTH_TOKEN
Authentication token of Jina Cloud
JINA_DEFAULT_HOST
The default host where the server is exposed
JINA_DEFAULT_TIMEOUT_CTRL
The default timeout time used by Flow to check the readiness of Executors
JINA_DEPLOYMENT_NAME
The name of the deployment, used by the Head Runtime in Kubernetes to connect to different deployments
JINA_DISABLE_UVLOOP
If set, Jina will not use uvloop event loop for concurrent execution
JINA_FULL_CLI
If set, all the CLI options will be shown in help
JINA_GATEWAY_IMAGE
Used when exporting a Flow to Kubernetes or docker-compose to override the default gateway image
JINA_GRPC_RECV_BYTES
Set by the grpc service to keep track of the received bytes
JINA_GRPC_SEND_BYTES
Set by the grpc service to keep track of the sent bytes
JINA_LOG_CONFIG
The configuration used for the logger
JINA_LOG_LEVEL
The logging level used: INFO, DEBUG, WARNING
JINA_LOG_NO_COLOR
If set, disables color from rich console
JINA_MP_START_METHOD
Sets the multiprocessing start method used by jina
JINA_RANDOM_PORT_MAX
The max port number used when selecting random ports to apply for Executors or gateway
JINA_RANDOM_PORT_MIN
The min port number used when selecting random ports to apply for Executors or gateway
JINA_LOCKS_ROOT
The root folder where file locks for concurrent Executor initialization
JINA_OPTOUT_TELEMETRY
If set, disables telemetry
JINA_K8S_ACCESS_MODES
Configures the access modes for the PersistentVolumeClaim attached to the StatefulSet, when creating a StatefulSet in Kubernetes for an Executor using volumes. Defaults to ‘[“ReadWriteOnce”]’
JINA_K8S_STORAGE_CLASS_NAME
Configures the storage class for the PersistentVolumeClaim attached to the StatefulSet, when creating a StatefulSet in Kubernetes for an Executor using volumes. Defaults to ‘standard’
JINA_K8S_STORAGE_CAPACITY
Configures the capacity for the PersistentVolumeClaim attached to the StatefulSet, when creating a StatefulSet in Kubernetes for an Executor using volumes. Defaults to ‘10G’
JINA_STREAMER_ARGS
Jina uses this variable to inject GatewayStreamer arguments into the host environment running a Gateway
