Authentication

Kitaru has two different server-auth concepts that fit together like a front-door key and a temporary visitor badge:

1. Service-account API keys are the long-lived automation credentials you create for CI, scripts, containers, and other non-human callers.
2. Bearer tokens are short-lived server access tokens derived from the currently active Kitaru connection. kitaru auth token prints one when you need to paste it into a raw HTTP request.

For OSS Kitaru automation, start with a service account + API key. Do not use personal access tokens (PATs) as the default Kitaru primitive; PATs are a Pro-only server feature and are documented separately from OSS Kitaru auth.

The credential chain

The normal machine-auth flow is:

service account -> long-lived API key -> Kitaru login/env config -> short-lived bearer token

Concretely:

1. Create a service account for the machine or automation job.
2. Create an API key for that service account.
3. Use that API key with kitaru login --api-key ... or KITARU_AUTH_TOKEN=....
4. When a raw HTTP call needs a bearer token, run kitaru auth token. Kitaru exchanges the active API-key-backed connection for a short-lived bearer token.

That final bearer token is useful for curl snippets, but it is not the long-lived secret you store in CI.

In automation, KITARU_AUTH_TOKEN is usually set to the long-lived service-account API key; kitaru auth token exchanges that active connection for a short-lived bearer token when a raw HTTP call needs one.

Create a service account and API key

Run these commands from an account that can manage server auth:

kitaru auth service-accounts create ci-runner \
  --description "CI runner for production deployments"

kitaru auth api-keys create ci-runner default -o json

The API-key create response includes a one-time key value:

{
  "command": "auth.api-keys.create",
  "item": {
    "name": "default",
    "service_account_name": "ci-runner",
    "active": true,
    "key": "kat_..."
  }
}

Store that key immediately in your secret manager. Kitaru can show API-key metadata later, but it cannot retrieve the raw key again.

Use the API key from CI or a container

For a non-interactive job, configure the server URL, service-account API key, and project:

export KITARU_SERVER_URL=https://kitaru.example.com
export KITARU_AUTH_TOKEN=kat_...
export KITARU_PROJECT=production

Or persist the same connection locally:

kitaru login https://kitaru.example.com \
  --api-key kat_... \
  --project production

KITARU_PROJECT is required for project-scoped operations such as running, listing, replaying, or invoking executions. Auth-management commands are server-level, so they can run with just a server URL and auth token when you are creating or rotating credentials.

Get a short-lived bearer token

Use kitaru auth token when a raw HTTP client needs an Authorization: Bearer header:

KITARU_SERVER_ACCESS_TOKEN="$(kitaru auth token)"

curl -H "Authorization: Bearer ${KITARU_SERVER_ACCESS_TOKEN}" \
  https://kitaru.example.com/api/v1/...

This command does not create a long-lived API key. It asks the active Kitaru server connection for a temporary bearer token. If your active connection was made with a service-account API key, the bearer token is derived from that API key.

Rotate an API key

To replace a long-lived API key:

kitaru auth api-keys rotate ci-runner default --retain-minutes 10 -o json

The rotate response includes the replacement key once. --retain-minutes keeps the old key valid for a short overlap window, which is useful when you need time to update CI secrets safely.

After updating your secret manager, verify the new key and delete credentials you no longer need:

kitaru auth api-keys list ci-runner
kitaru auth api-keys delete ci-runner old-key --yes

SDK usage

The Python SDK exposes the same OSS-first auth-management surface:

from kitaru import KitaruClient

client = KitaruClient.for_auth_management()
service_account = client.auth.service_accounts.create(
    "ci-runner",
    description="CI runner for production deployments",
)
api_key = client.auth.api_keys.create(service_account.name, "default")

print(api_key.api_key.name)
print(api_key.key)  # one-time value: store it now

Use KitaruClient.for_auth_management() for server-level credential administration. Use normal KitaruClient() for project-scoped execution, artifact, memory, and deployment operations.
