Fixes #160

Add Service-on-Demand support to ocean-cli

Adds full CLI support for Service-on-Demand — launching long-running Docker
containers (JupyterLab, inference servers, nginx, …) on an Ocean Node compute
environment, paid up-front via on-chain escrow for a requested duration, and
reachable through forwarded ports. Unlike a compute job (runs an algorithm to
completion and exits), a service stays up until it expires, is stopped, or
is extended.

New commands (8)

Command Aliases Purpose
getServiceTemplates serviceTemplates List the node's service templates + compatible environments
startService Pay & launch a service (from --template or --image)
getServiceStatus myServices Show your service(s) with full detail + endpoints
getServices listServices SERVICES_LIST — list services across all owners (docker spec stripped), with --status/--include-all/--from filters
serviceLogs computeServiceLogs Stream a service's container logs (optional --since)
extendService Pay to push the expiry out
restartService Recreate the container (same ports/expiry, free); optional --cmd/--entrypoint override
stopService Tear the service down

All commands support both positional args and named options, work over HTTP and
P2P (transport auto-selected by ocean.js), and are picked up automatically by the
interactive REPL (no manual command-list maintenance).

Changes

  • src/serviceHelpers.ts (new) — pure, testable helpers: status labels &
    coloring, environment↔template resource matching (availableFor,
    envSatisfiesTemplate, findServiceEnvironments, templateMismatchReason),
    default-resource resolution, client-side cost estimation, userData
    parsing/validation (keys-only echo — values are never logged), escrow
    pre-verification with actionable remediation output, status polling, and a
    human-first job pretty-printer.
  • src/commands.ts — eight new Commands methods plus a shared payment-prompt
    helper. startService orchestrates the full flow: resolve env → resolve
    container spec (template and/or explicit flags, with the template.command → dockerCmd / template.entrypoint → dockerEntrypoint rename) → resolve
    resources → estimate cost → pre-verify escrow → confirm → start → poll to
    Running and print the endpoint.
  • src/cli.ts — command registration + option parsing (ports, JSON
    cmd/entrypoint, status filter). Read-only getServiceTemplates/getServices
    accept an optional --node target, mirroring getComputeEnvironments.
  • test/serviceFlow.test.ts (new) — end-to-end system test covering the full
    lifecycle, with a skipLifecycle guard so it skips cleanly on a node without
    services support.
  • README.md — feature bullet, a "Service-on-Demand" examples section, and a
    per-command option reference for all eight commands.

Notable correctness details

  • serviceRestart arg order (#2114): dockerCmd/dockerEntrypoint sit between
    userData and signal — the call passes all three before the AbortSignal.
  • getServices is node-wide, not owner-scoped (#2115): returns ServiceJobListed
    (docker image-spec fields stripped); results may include other owners' services.
  • serviceGetStreamableLogs (#2113): returns an async-iterable or null
    the null case is handled, and consumption reuses the exact buffer-then-print
    pattern from computeStreamableLogs (no forced timeout — logs are long-lived).
  • Escrow is pre-verified client-side before start/extend (shortfalls otherwise
    surface only as an async Error/*Failed status), and the CLI prints the exact
    depositEscrow / authorizeEscrow remediation commands on failure.
  • userData values are never logged — only keys are echoed.
  • Interactive-loop-safe: service Commands methods never process.exit on
    recoverable errors; the payment prompt opens its own readline (the REPL pauses to
    yield stdin), mirroring startCompute.

Testing

Verified end-to-end against a running barge (ocean-node v4) — all eight commands,
both the happy path and failure/skip paths. test/serviceFlow.test.ts passes
10/10 in ~40 s using a lightweight custom image
(nginxinc/nginx-unprivileged:alpine on port 8080):

✔ lists service templates with 'getServiceTemplates'
✔ finds a compute environment with services enabled
✔ funds escrow (deposit + authorize the env consumer)
✔ starts a service and reaches Running with an endpoint
✔ shows the service via getServiceStatus (single + list)
✔ lists the service via getServices (SERVICES_LIST) without docker spec
✔ fetches service logs (lenient)
✔ extends the service expiry with extendService
✔ restarts the container with restartService
✔ stops the service with stopService
10 passing (40s)

The client-side cost estimate matched the node-computed cost exactly, and
getServices confirmed that dockerCmd/dockerEntrypoint/dockerfile are
stripped from ServiceJobListed.

AI automated code review (Gemini 3).

Overall risk: low

Summary:
This is an excellent PR introducing the Service-on-Demand lifecycle commands. The architectural split between CLI parsing, core actions, and helpers is clean. Input validation, cost estimations, interactive prompts, and robust polling (especially the old container ID check during restarts) are very well implemented. A few minor informational suggestions are provided for edge cases.

Comments:
• [INFO][style] options.env is not defined as an option for the startService command (only as a positional <computeEnvId>). This fallback is redundant but harmless. You could simplify this to const envId = computeEnvId;.
• [INFO][logic] Because template values are copied before explicit flags are applied, if a template has a tag and the user explicitly passes --checksum, both tag and checksum will be truthy. This causes specCount > 1 and triggers the validation error below. Since cli.ts already prevents mixing --template and --image, this is perfectly fine for now, but worth noting if you ever want to allow users to override a template's image specifications in the future.
• [INFO][style] The userData file and inline parsing logic here works perfectly, though it duplicates some of the validation logic found in parseUserData inside src/serviceHelpers.ts. Since template validation isn't strictly needed for a restart, this is acceptable, but consider reusing parseUserData if you wish to completely centralize the parsing logic.
• [INFO][logic] The use of notContainerId to avoid race conditions when checking for Running status immediately after a restart is a fantastic piece of defensive programming. Excellent handling of this edge case!

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Guard expiresAt before toISOString().

If oldExpiry or newJob.expiresAt is undefined/0, new Date(...).toISOString() throws RangeError. Since this runs after serviceExtend succeeds, the throw is swallowed by the outer catch and the user sees "Error extending service" despite a successful (paid) extend. printServiceJob already guards this same field.

🛡️ Suggested guard
-      console.log(chalk.green(`Service ${serviceId} extended.`));
-      console.log(
-        `  expiry: ${new Date(oldExpiry).toISOString()} → ${new Date(
-          newJob.expiresAt
-        ).toISOString()}`
-      );
+      console.log(chalk.green(`Service ${serviceId} extended.`));
+      const fmt = (t?: number) =>
+        typeof t === "number" && t > 0 ? new Date(t).toISOString() : "n/a";
+      console.log(`  expiry: ${fmt(oldExpiry)} → ${fmt(newJob.expiresAt)}`);

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

homedir from os is a function; ${homedir} never calls it. Both default-path constructions interpolate the function reference instead of the resolved home directory, producing an invalid ADDRESS file path. Call homedir().

  • test/serviceFlow.test.ts#L40-L49: change ${homedir} to ${homedir()} in getAddresses.
  • test/serviceFlow.test.ts#L62-L72: change ${homedir} to ${homedir()} in the before hook default.
