Module api

Expand description

The daemon’s JSON API, version 1: the request and response types every client deserializes, and the principal a transport authenticates. Plain data only: no I/O, no Docker or GitHub types, no secrets but a Pairing’s one-time link, which its Debug leaves out.

Routes, all under the authenticated principal:

Structs§

Activity: GET /v1/activity: every job runnerd’s runners started or finished in a window, by when that happened rather than when the job was queued, so a job that waited or ran long counts in the window it started or ended in.
ActivityQuery: GET /v1/activity query parameters.
Admission: How a job’s runner was admitted.
AutoPlan: What auto sizing will do: its rules, the changes its next look would make as the history and config are now, and the profiles a recent change holds.
Budget: The memory budget runners and the mirror share, in bytes.
BuildCacheCounts: What the shared build cache served one runner and took from it (ADR 0052), counted by the cache itself.
BuildCacheStats: The shared build cache (ADR 0052): its size now, and what it served the jobs of the last 7 days.
Busy: The body of a 409 refused because runners use what the request would change. Has the message of an ErrorResponse, so a client that reads only that still gets it.
CacheHistory: GET /v1/caches/history: every measurement, oldest first.
CacheHistoryQuery: GET /v1/caches/history query parameters.
CacheSize: One volume’s size at one measurement.
CacheVolume: One cache volume and its size.
Caches: GET /v1/caches: every cache volume of the configured profiles, as last measured. Docker measures volumes slowly, so runnerd measures them at start and whenever no runner runs after jobs ended.
Check: One thing the host needs to run runners. Its Display is the line runnerd doctor prints.
ConfigCheck: POST /v1/config/check and PUT /v1/config: what runnerd check-config prints for a config. PUT refuses an invalid one with 422 and this body, which has an ErrorResponse’s message.
ConfigFile: GET /v1/config: the config the daemon runs with. Parse text with config::Config::parse for its fields.
CpuAdmission: What a runner reserved of the CPU budget. CPU in millicores, times in seconds.
CpuBudget: The CPU budget runners share, in millicores.
Dashboard: GET /v1/dashboard: the dashboard’s [web] settings, as the daemon read them when it started.
Delivery: What one target did with a message.
Digest: GET /v1/digest: the last 24 hours.
Doctor: GET /v1/doctor: what runnerd doctor checks, for the config the daemon runs with.
ErrorResponse: The body of every error response.
EventEnvelope: One event as GET /v1/events sends it: the SSE data field. The SSE event field is event.kind() and the SSE id field is id.

HostSample: One sample of the whole slice runners run in.
HostSampleQuery: GET /v1/host/samples query parameters.

Insight: One thing the history says, about one job or one repository.
Insights: GET /v1/insights: what the history says about the window.
InsightsQuery: GET /v1/insights query parameters.
Job: GET /v1/jobs/{id}: a job with its steps.
JobMetrics: What a job used, over the samples taken while it ran (every few seconds). None until a sample exists.

JobQuery: GET /v1/jobs query parameters. Jobs come newest first (by ID, which grows with time).
JobRunner: The runner a job ran on.
JobSizing: The jobs of one name in one workflow of one repository.
JobSummary: A job without its steps: what lists and events carry.
LogQuery: GET /v1/jobs/{id}/logs query parameters. The response is text/plain, one log line per line.
LogSummary: A job’s stored log.
LongWait: A job that waited.
Notification: What a webhook target is posted, as JSON; an ntfy target gets its title, message, priority and link.
NotifyTest: POST /v1/notify/test: what each target did with a test message.

PauseQuery: POST /v1/repositories/{owner}/{name}/pause and POST /v1/repositories/pause query parameters.
Paused: POST /v1/repositories/{owner}/{name}/pause and POST /v1/repositories/pause: the repository, or every one, is paused, and stays paused when the daemon restarts.
Peaks: The peaks of a set of jobs, each the highest of its samples.
ProfileSizing: One profile: its limits now, its jobs’ peaks and waits, and the advice.
ProfileStatus: A runner profile and what runs in its slots.
QueuedJob: A queued job runners of this daemon can take, as GitHub listed it at the last poll.
Record: One record: the runner of a failed job as the job left it.
RecordLimits: The limits on records, from [records] in the config.
RecordNote: What the job history keeps about a failed job’s record, after the record is gone too.
Records: GET /v1/records: every record, oldest first, and the limits they are kept within.
RemoveRecordsQuery: DELETE /v1/records query parameters: exactly one of them.
RemovedRecords: DELETE /v1/records…: what was removed.

SizingQuery: GET /v1/sizing query parameters.
SlotStatus: One slot of a profile: room for one job.
Spread: Percentiles of a set of values, by nearest rank: each is one of the values, and with fewer than 100 values p99 is the largest.
Started: A job that started: when, and how long it had waited since it was queued.
Starts: A profile’s jobs by whether their runner was already up when GitHub queued them (ADR 0050).
Stats: GET /v1/stats: finished jobs per repository and time bucket, for trends. Sums, so clients can average.

Enums§

AdmissionPolicy: [host] admission, as a job’s record and the budget name it.
Advice: What to set a profile’s memory and slots to. memory is the largest sampled peak plus the margin, rounded up to 256M: the cap kills a job that goes over it, so it is sized for the heaviest run, not a percentile.
AutoNote: What auto sizing does about a job near its cap.
Basis: What a runner reserved goes by, in the order measured admission falls back.
Bucket: How GET /v1/stats groups jobs in time.
CacheKind: What a cache volume holds.
CheckStatus: How a Check came out.
Event: Everything that happens, tagged by type.
InsightKind: What an insight is, tagged by kind.
JobPeak: Which of a job’s own peaks Basis::Job goes by.
JobState: Where a job is in its life, as this daemon saw it.
NotifyEvent: What a notification target is sent, and the events [notify] targets choose from.
Principal: Who sent a request, as the transport authenticated it. Handlers get it from one place, so a new transport only has to produce one.
Priority: How urgent a notification is, as ntfy ranks it.
RecordRemoval: Why a record was removed.
Severity: How much an insight matters.
WaitKind: What a Waiting reason waits on, which clients draw it by.
Waiting: Why a queued job has no runner of its own yet. Jobs are served oldest first; each takes the first of these that holds for it.

Constants§

INSIGHT_DAYS: The window GET /v1/insights reads by default, in days.
INSIGHT_DAYS_MAX: The longest window GET /v1/insights reads, in days.
SHELL_PROTOCOL: The Upgrade protocol of POST /v1/records/{job}/shell: after 101 Switching Protocols the connection carries the shell’s terminal, raw bytes both ways.

Functions§

cores: Millicores as a number of CPUs to a tenth, rounded up: 2.5, 32.
cpus: Millicores as 2.5 CPUs or 1 CPU, to a tenth rounded up.
period: A setting’s length in words, as a config’s periods read: 5 minutes, 24 hours, 90 s.
