Schedule Cron

A scheduled template is a job-mode template that Fibe launches on a cron schedule. The scheduler creates a new Playground each fire; the Playground exits when watched services complete; the result is recorded.

Required pieces​

  1. x-fibe.gg.metadata.job_mode: true.
  2. At least one service with fibe.gg/job_watch: "true".
  3. x-fibe.gg.metadata.schedule_config with enabled, cron, marquee_id.
x-fibe.gg:
  metadata:
    description: "Nightly DB backup"
    category: "Operations"
    job_mode: true
    schedule_config:
      enabled: true
      cron: "0 3 * * *"          # 3:00 daily, UTC by default
      marquee_id: 1

cron field​

5-field POSIX cron expression:

min hour day-of-month month day-of-week
0   3    *            *     *           ← daily at 3:00
*/5 *    *            *     *           ← every 5 minutes
0   */2  *            *     *           ← every 2 hours
0   0    1            *     *           ← first of every month at midnight
30  6    *            *     1-5         ← 06:30 Mon-Fri

Schedule is interpreted in UTC by default. If the runtime supports per-Marquee timezone overrides, that's a separate config; check current docs.

marquee_id​

The Marquee where each fired Playground runs. Required. Must be a Marquee the Player owns. Schema validates shape (positive integer, or ^[1-9][0-9]*$ string); runtime resolves and authorizes.

schedule_config:
  enabled: true
  cron: "0 3 * * *"
  marquee_id: 1                   # integer
schedule_config:
  marquee_id: "1"                 # string form, also valid

enabled​

Boolean — disable without removing the schedule config by setting enabled: false. Useful for templates that ship with a schedule but should not auto-fire until explicitly opted in.

Combining with trigger_config​

Same template can fire on schedule AND on VCS triggers — declare both schedule_config AND trigger_config. Fibe launches independently for each:

x-fibe.gg:
  metadata:
    job_mode: true
    schedule_config:
      enabled: true
      cron: "0 3 * * *"
      marquee_id: 1
    trigger_config:
      enabled: true
      event_type: push
      repo_url: https://github.com/owner/repo
      branch: main
      prop_id: 1
      marquee_id: 1

What runtime does​

  • At each cron fire, creates a new job-mode Playground from the template.
  • Forces restart: "no" and deploy.replicas: 1.
  • Runs until watched services exit.
  • Records result (success/failure, logs, duration).
  • Tears down the Playground after completion.

Where to find run history​

fibe_resource_list(resource: "trick", params: { ... }) lists past runs of job-mode templates. Filter by template ID to see only this template's history. See platform skill fibe-tool-resource-list.

Worked example: nightly Postgres backup​

services:
  backup:
    image: postgres:17
    environment:
      PGHOST: $$var__PG_HOST
      PGUSER: $$var__PG_USER
      PGPASSWORD: $$var__PG_PASS
      PGDATABASE: $$var__PG_DB
      S3_BUCKET: $$var__S3_BUCKET
      S3_KEY_ID: $$var__S3_KEY_ID
      S3_SECRET: $$var__S3_SECRET
    command:
      - /bin/bash
      - -ec
      - |
        TS=$(date -u +%Y%m%dT%H%M%SZ)
        FILE=/tmp/${PGDATABASE}-${TS}.sql.gz
        pg_dump --no-owner | gzip > "$FILE"
        AWS_ACCESS_KEY_ID="$S3_KEY_ID" AWS_SECRET_ACCESS_KEY="$S3_SECRET" \
          aws s3 cp "$FILE" "s3://$S3_BUCKET/$(basename "$FILE")"
    labels:
      fibe.gg/job_watch: "true"
    restart: "no"

x-fibe.gg:
  metadata:
    description: "Nightly Postgres → S3 backup"
    category: "Operations"
    job_mode: true
    schedule_config:
      enabled: true
      cron: "0 3 * * *"
      marquee_id: 1

  variables:
    PG_HOST:
      name: "Postgres host"
      required: true
    PG_USER:
      name: "Postgres user"
      required: true
      default: "postgres"
    PG_PASS:
      name: "Postgres password"
      required: true
      secret: true
      sensitive: true
    PG_DB:
      name: "Postgres database"
      required: true
    S3_BUCKET:
      name: "S3 bucket"
      required: true
    S3_KEY_ID:
      name: "S3 access key ID"
      required: true
      secret: true
    S3_SECRET:
      name: "S3 secret access key"
      required: true
      secret: true
      sensitive: true

Pitfalls​

  • schedule_config without job_mode: true — schedule does nothing; long-running templates aren't fireable on schedule.
  • Missing marquee_id — schema accepts (no marquee_id is technically additionalProperties: true), but runtime requires it. Always set.
  • Invalid cron expression — schema only checks it's a string. Runtime parses. Test the cron with an external tool first.
  • Cron fires while previous run is still active — typically Fibe just spawns another Playground (parallel runs). If your job is non-idempotent (e.g. modifying a shared DB), guard with a lock or change the cadence.
  • Long-running tasks with tight crontab — */1 * * * * for a job that takes 90 seconds = unbounded growth. Make the period > max job duration.
  • Mistaking schedule UTC for local time — verify by sending a one-off Mutter with a timestamp at fire.
