EnvVarsApi #

Manage user account environment variables in Hopsworks.

Account env vars are encrypted at rest and automatically injected into every runtime the user starts (jobs, deployments, apps, Jupyter, terminal). Per-runtime env vars override account-level on collision.

Example

import hopsworks
hopsworks.login()
api = hopsworks.get_env_vars_api()

api.create_env_var("OPENAI_API_KEY", "sk-...")
api.create_env_var("HF_TOKEN", "hf_...")

# Print only names — values are typically credentials, don't log them.
for v in api.get_env_vars():
    print(v.name)

api.delete_env_var("OPENAI_API_KEY")

Returned by

hopsworks.get_env_vars_api

create_env_var #

create_env_var(name: str, value: str) -> env_var.EnvVar

Add a new account-level env var.

Example

api.create_env_var("OPENAI_API_KEY", "sk-...")

PARAMETER	DESCRIPTION
`name`	Variable name. Must match `^[A-Za-z_][A-Za-z0-9_]$` and not be reserved by the platform (`API_KEY`, `HOPS_`, `HOPSWORKS_`, etc — see `ReservedEnvVars` in the backend). TYPE:* `str`
`value`	Variable value. Up to 8192 characters. TYPE: `str`

RETURNS	DESCRIPTION
`env_var.EnvVar`	The created `EnvVar`.

RAISES	DESCRIPTION
`hopsworks.client.exceptions.RestAPIError`	`ENV_VAR_RESERVED_NAME`, `ENV_VAR_INVALID_NAME`, `ENV_VAR_VALUE_TOO_LARGE`, or `ENV_VAR_LIMIT_EXCEEDED` (default cap is 64 vars per user).

delete #

delete(name: str) -> None

Alias for delete_env_var.

Kept for parity with SecretsApi.delete. New code should prefer delete_env_var.

PARAMETER	DESCRIPTION
`name`	Variable name to remove. TYPE: `str`

delete_all #

delete_all() -> None

Remove all account-level env vars for the authenticated user.

Returns silently if there are none.

Example

api.delete_all()
assert api.get_env_vars() == []

delete_env_var #

delete_env_var(name: str) -> None

Remove a single env var from the account.

Example

api.delete_env_var("OPENAI_API_KEY")

PARAMETER	DESCRIPTION
`name`	Variable name to remove. TYPE: `str`

RAISES	DESCRIPTION
`hopsworks.client.exceptions.RestAPIError`	`ENV_VAR_NOT_FOUND` if no env var with that name exists.

get #

get(name: str) -> str | None

Return just the value of an env var, or None if missing.

Convenience wrapper around get_env_var.

Example

api.get("OPENAI_API_KEY")  # -> "sk-..." or None

PARAMETER	DESCRIPTION
`name`	Variable name. TYPE: `str`

RETURNS	DESCRIPTION
`str \| None`	The env var's value, or `None` when no var with that name exists.

get_env_var #

get_env_var(name: str) -> env_var.EnvVar | None

Look up a single env var by name.

Returns None when no env var with that name exists, instead of raising — convenient for "set if missing" patterns.

PARAMETER	DESCRIPTION
`name`	Variable name (e.g. `"OPENAI_API_KEY"`). TYPE: `str`

RETURNS	DESCRIPTION
`env_var.EnvVar \| None`	The matching `EnvVar`, or `None`.

get_env_vars #

get_env_vars(
    include_value: bool = True,
) -> list[env_var.EnvVar]

Return all account-level env vars for the authenticated user.

The backend omits values from the list response by default to reduce accidental exposure (UI, logs, proxies). The SDK opts back in here so existing callers see EnvVar.value populated; pass include_value=False if you only need names (e.g. building a UI list before drilling into a single var).

PARAMETER	DESCRIPTION
`include_value`	When `False`, the returned EnvVars have no value set. Default `True` preserves the existing behavior. TYPE: `bool` DEFAULT: `True`

RETURNS	DESCRIPTION
`list[env_var.EnvVar]`	List of `EnvVar` objects, possibly empty.

set_env_var #

set_env_var(name: str, value: str) -> env_var.EnvVar

Upsert: create the env var if missing, else update its value.

Example

# Idempotent — safe to call from setup scripts
api.set_env_var("HF_TOKEN", os.environ["HF_TOKEN"])

PARAMETER	DESCRIPTION
`name`	Variable name. TYPE: `str`
`value`	Variable value. TYPE: `str`

RETURNS	DESCRIPTION
`env_var.EnvVar`	The created or updated `EnvVar`.

update_env_var #

update_env_var(name: str, value: str) -> env_var.EnvVar

Replace the value of an existing env var.

Use set_env_var to upsert (create-if-missing) instead.

PARAMETER	DESCRIPTION
`name`	Variable name. Must already exist. TYPE: `str`
`value`	New value. Up to 8192 characters. TYPE: `str`

RETURNS	DESCRIPTION
`env_var.EnvVar`	The updated `EnvVar`.

RAISES	DESCRIPTION
`hopsworks.client.exceptions.RestAPIError`	`ENV_VAR_NOT_FOUND` if no env var with that name exists.
