Tail App Logs

POST
/containers.api.v1.AppService/TailAppLogs

Streams an App's retained output, merged across replicas and tagged with the replica that produced each chunk, starting after from_offset. Replays at most limit history chunks (0 means 1000); with follow it then polls for new output every second, ending after 30 idle minutes when the App has no live replica. replica narrows to one replica.

Access: namespace VIEWER or above (read)

Authorization

AuthorizationBearer <token>

A namespace-scoped API key (cpk_…) for machines, or a Xeonr Auth OIDC token for humans. The key's namespace and role are pinned server-side.

Header Parameters

Connect-Protocol-Version?number

Define the version of the Connect protocol

Connect-Timeout-Ms?number

Define the timeout, in ms

Request Body

application/connect+json

appId?string
Length1 <= length <= 64
replica?string

Restrict to a single replica. Empty = every replica, merged.

Lengthlength <= 256
fromOffset?string

Resume after this cursor. 0 starts at the oldest retained chunk; a negative cursor reads the same as 0.

Formatint64
Range0 <= value
follow?boolean

Stay open and stream new output as it arrives. False returns the retained history and ends, which is what a one-shot fetch wants. validate:skip a bool has no bounds

limit?integer

Cap on history chunks replayed before live output begins. 0 = server default (1000). validate:skip no server-side ceiling; 0 means 1000

[key: string]?never

Rotate App Key POST

Issues a new App key and invalidates the previous one. The new key is returned and stays readable through GetApp. **Access:** namespace OPERATOR or above (write)

Update App POST

Changes an App's operational envelope in place: scaling, resources, env, egress and label. Only fields named in update_mask are applied; an empty mask applies all of them (scaling only when set). An egress change takes effect by replacing replicas once the App is idle. Also repairs a stored hostname or a missing key. access and auto_start are not applied by this call today. **Access:** namespace OPERATOR or above (write)
