The process environment is returned by `Spawner.get_env`, which specifies the following environment variables:
|
||||
|
||||
- JUPYTERHUB_SERVICE_URL - the \_bind* URL where the server should launch its HTTP server (`http://127.0.0.1:12345`).
|
||||
- `JUPYTERHUB_SERVICE_URL` - the _bind_ URL where the server should launch its HTTP server (`http://127.0.0.1:12345`).
|
||||
This includes `Spawner.ip` and `Spawner.port`; _new in 2.0, prior to 2.0 IP, port were on the command-line and only if specified_
|
||||
- JUPYTERHUB_SERVICE_PREFIX - the URL prefix the service will run on (e.g. `/user/name/`)
|
||||
- JUPYTERHUB_USER - the JupyterHub user's username
|
||||
- JUPYTERHUB_SERVER_NAME - the server's name, if using named servers (default server has an empty name)
|
||||
- JUPYTERHUB_API_URL - the full URL for the JupyterHub API (http://17.0.0.1:8001/hub/api)
|
||||
- JUPYTERHUB_BASE_URL - the base URL of the whole jupyterhub deployment, i.e. the bit before `hub/` or `user/`,
|
||||
- `JUPYTERHUB_SERVICE_PREFIX` - the URL prefix the service will run on (e.g. `/user/name/`)
|
||||
- `JUPYTERHUB_USER` - the JupyterHub user's username

- `JUPYTERHUB_BASE_URL` - the base URL of the whole jupyterhub deployment, i.e. the bit before `hub/` or `user/`,
|
||||
as set by `c.JupyterHub.base_url` (default: `/`)
|
||||
- JUPYTERHUB_API_TOKEN - the API token the server can use to make requests to the Hub.
|
||||
- `JUPYTERHUB_API_TOKEN` - the API token the server can use to make requests to the Hub.
|
||||
This is also the OAuth client secret.
|
||||
- JUPYTERHUB_CLIENT_ID - the OAuth client ID for authenticating visitors.
|
||||
- JUPYTERHUB_OAUTH_CALLBACK_URL - the callback URL to use in OAuth, typically `/user/:name/oauth_callback`
|

|
||||
- `JUPYTERHUB_CLIENT_ID` - the OAuth client ID for authenticating visitors.

- `JUPYTERHUB_OAUTH_CLIENT_ALLOWED_SCOPES` - the scopes the service is allowed to request.
|
||||
If no scopes are requested explicitly, these scopes will be requested.
|

Optional environment variables, depending on configuration:
|
||||
|
||||
- JUPYTERHUB_SSL_[KEYFILE|CERTFILE|CLIENT_CI] - SSL configuration, when `internal_ssl` is enabled
|
||||
- JUPYTERHUB_ROOT_DIR - the root directory of the server (notebook directory), when `Spawner.notebook_dir` is defined (new in 2.0)
|
||||
- JUPYTERHUB_DEFAULT_URL - the default URL for the server (for redirects from `/user/:name/`),
|
||||
- `JUPYTERHUB_SSL_[KEYFILE|CERTFILE|CLIENT_CI]` - SSL configuration, when `internal_ssl` is enabled
|
||||

|
||||
if `Spawner.default_url` is defined
|
||||
(new in 2.0, previously passed via CLI)
|
||||
- JUPYTERHUB_DEBUG=1 - generic debug flag, sets maximum log level when `Spawner.debug` is True

|
||||
(new in 2.0, previously passed via CLI)
|
||||
- JUPYTERHUB_DISABLE_USER_CONFIG=1 - disable loading user config,
|
||||
- `JUPYTERHUB_DISABLE_USER_CONFIG=1` - disable loading user config,

|
||||
|
||||
- JUPYTERHUB_[MEM|CPU]_[LIMIT_GUARANTEE] - the values of CPU and memory limits and guarantees.
|
||||
- `JUPYTERHUB_[MEM|CPU]_[LIMIT_GUARANTEE]` - the values of CPU and memory limits and guarantees.
