GitHub App provider

The GitHub App is KiCI’s flagship source. A single App:

  1. receives push, pull_request, and related events from every repo it’s installed on,
  2. clones repos with a short-lived installation token (no deploy key to manage),
  3. posts workflow / job / step Check runs back to the commit — visible on the commit view for a plain push and on the Checks tab of any pull request that contains it (see GitHub checks architecture).

You don’t need an App for every scenario — if you only care about push events, don’t want to install an App, or are using a non-GitHub forge, use the universal-git provider instead.

Both paths reach the same trigger pipeline; they differ in what the forge side looks like:

CapabilityGitHub App (this guide)github-repo preset on universal-git
Webhook sourceApp-level webhook (one per App)Per-repo webhook (one per repo)
Clone authInstallation token (auto, short-lived)PAT or SSH deploy key (you manage rotation)
Check runs on pull requestsYes — full KiCI Checks UINo (status post only via custom step)
Cross-repo install in secondsYes (install the App on more repos)No (new webhook per repo)
Works without a GitHub org adminNo (App creation is org-scoped)Yes (per-repo webhook is repo-admin)
Works on Forgejo / Gitea / Gogs / GitLabNoYes (other presets)

Use the App when you can; the github-repo preset is a fallback for repos where you can’t install an App.

kici-admin source add github --manifest creates and configures the GitHub App for you via GitHub’s App Manifest flow. KiCI builds a manifest with the exact permissions, events, webhook URL, and webhook secret baked in, so you never pick permissions, paste a URL, generate a secret, or download a .pem by hand — the App is correct by construction.

Terminal window
kici-admin --url http://<orchestrator-host>:4000 --token $KICI_BOOTSTRAP_ADMIN_TOKEN \
source add github --manifest --name my-org --github-org my-org

--github-org <slug> creates the App under a GitHub organization (the <slug> is the org’s github.com/<slug> URL slug, not its display name) — the recommended default, since org-owned Apps can be installed across the org. Drop the flag only when you deliberately want a personal-account App, which can be installed solely on repos you own. You need permission to create Apps in that org (be an org owner, or have the org allow member App creation).

What happens:

  1. The CLI resolves your org’s webhook URL and opens GitHub with a pre-filled App manifest. You click “Create GitHub App” once — the only manual step.
  2. GitHub redirects back to a localhost callback; the CLI exchanges the returned setup code for the App’s id, private key, and webhook secret. The private key is exchanged and stored only on your orchestrator host — it never transits the KiCI Platform.
  3. The CLI stores the credentials encrypted under KICI_SECRET_KEY and registers the routing key github:<appId>, reusing the same storage path as the manual flow.
  4. It opens the App’s install page so you can pick repos, then verifies end-to-end: it waits for the installation, mints an installation token, and confirms repo access before declaring success.
$ kici-admin source add github --manifest --name my-org --github-org my-org
→ Opening GitHub to create your App…
→ ✓ App created (id 12345), credentials captured
→ ✓ Stored on orchestrator (encrypted), registered as github:12345
→ Install the App on your repos: https://github.com/apps/my-org/installations/new
→ ✓ Installation detected (account my-org)
→ ✓ Credentials verified (3 repositories reachable)
GitHub App "my-org" is live.
Webhook: https://<platform-host>/webhook/<orgId>/github

In platform and hybrid mode the baked webhook URL is the hosted Platform’s (https://<platform-host>/webhook/<orgId>/github). In observed and independent mode it is the orchestrator’s own (<KICI_WEBHOOK_PUBLIC_URL>/webhook/<orgId>/github; independent mode uses __default__ as the org segment). --webhook-url overrides it in every mode.

Flags:

FlagEffect
--name <name>The App name you request on GitHub (required). GitHub assigns the final name + slug; the stored, displayed name always comes from GitHub (see Display name and slug).
--github-org <slug>Create the App under a GitHub organization instead of your personal account.
--webhook-url <url>Advanced / self-hosted. Bake this https:// URL into the App’s webhook verbatim instead of the URL the orchestrator resolves for its mode. See Self-hosted webhook URL.
--no-browserHeadless mode: the CLI prints a kici.dev URL to open, then reads the setup code you paste back. The page is pure client-side — it only displays the short-lived code, which is useless once the CLI exchanges it.

The org of the source. On an orchestrator attached to the Platform, the new source belongs to the org the orchestrator is attached to: the org that kici-admin orchestrator status, kici compile and the dashboard show. Its runs use that org’s contexts, secrets and fork policy. --org <orgId> accepts only that org; the CLI checks it before it creates the App. On an independent orchestrator the source belongs to __default__. The command prints the org on an Org: line. See Which org a source belongs to.

The manifest flow always creates a new App on GitHub. If a source for that App id already exists on the orchestrator, the command refuses — use source update to rotate an existing App’s credentials.

If any step after App creation fails (e.g. storage), the CLI prints the captured App id and writes the private key to a 0600 file, then tells you how to finish with the manual source add github command — so a created App is never orphaned.

An independent orchestrator receives App deliveries on its own direct ingress. The manifest flow bakes <KICI_WEBHOOK_PUBLIC_URL>/webhook/__default__/github, so set KICI_WEBHOOK_PUBLIC_URL first. See Direct GitHub ingress.

When you’d rather create the App by hand — or your environment can’t run the manifest flow — follow these steps.

  1. Decide the App scope. User-owned Apps can only be installed on repos you own; organization-owned Apps can be installed anywhere in the org. For production, create the App under the org.

  2. Create the App. Go to Settings -> Developer settings -> GitHub Apps -> New GitHub App (org-level is Settings -> Developer settings -> GitHub Apps on the org page).

  3. Set the webhook URL. The URL depends on the orchestrator’s mode:

    • platform and hybrid: the hosted Platform endpoint, one per org. The Platform relays each delivery to your orchestrator over its outbound connection.

      https://<platform-host>/webhook/<orgId>/github
    • observed and independent: the orchestrator’s own URL. Use the org-scoped URL for an App-level webhook, or the per-source URL <KICI_WEBHOOK_PUBLIC_URL>/webhook/<orgId>/github/<source-id> for a classic repository webhook. An independent orchestrator uses __default__ as the <orgId> segment.

      <KICI_WEBHOOK_PUBLIC_URL>/webhook/<orgId>/github

    The <orgId> segment is the KiCI organization ID the source belongs to; the <appId> is discovered from X-GitHub-Hook-Installation-Target-ID at request time and is not part of the URL.

  4. Set the webhook secret. Generate a random hex string (e.g. openssl rand -hex 32) and save it for step 4 of the orchestrator registration below. GitHub uses this secret to HMAC-sign every webhook; KiCI rejects mismatches.

  5. Pick permissions. Minimum required:

    ScopeAccessWhy
    Repository -> ContentsReadClone the repo to read the lock file
    Repository -> MetadataRead (auto)Default for every App
    Repository -> Pull requestsReadMatch pull_request triggers
    Repository -> ChecksRead & writePost KiCI’s enriched Check runs
    Repository -> IssuesReadReceive issue_comment events: /kici approve and /kici reject comments

    These cover the whole flow: clone, trigger matching, Check runs, and pull-request comment commands. CI trust needs no permission of its own — it reads the fork relationship straight out of the webhook payload and calls no GitHub API.

  6. Subscribe to events. At minimum: push, pull_request, check_run, check_suite, and issue_comment. GitHub offers issue_comment only after you grant the Issues permission above. Add others (issues, release, …) if your workflows use those triggers.

  7. Generate a private key. Scroll to the bottom of the App settings and click Generate a private key. A .pem file downloads — store it safely; you cannot redownload it.

  8. Copy the App ID. It’s the numeric ID near the top of the App settings page. You’ll need it for --app-id below.

  9. Install the App on target repos. Under the App’s Install App tab, install it on the repos (or whole org) that should trigger KiCI runs. Re-install to add repos later — this is live and revocable without redeploying the App.

With the App ID, private key .pem, and webhook secret in hand:

Terminal window
kici-admin --url http://<orchestrator-host>:4000 --token $KICI_BOOTSTRAP_ADMIN_TOKEN \
source add github \
--name my-org \
--app-id 12345 \
--private-key @/path/to/private-key.pem \
--webhook-secret <the-webhook-secret-from-step-4>

The command prints the routing key (always github:<appId>) and the public webhook URL to paste into the GitHub App’s “Webhook URL” field:

Source added: github:<appId> (my-org)
Webhook URL: https://<platform-host>/webhook/<orgId>/github
↳ Paste this into your GitHub App's "Webhook URL" field.

In observed and independent mode the URL is the orchestrator’s own per-source URL, <KICI_WEBHOOK_PUBLIC_URL>/webhook/<orgId>/github/<source-id>. When KICI_WEBHOOK_PUBLIC_URL is not set, the line reads (unavailable — KICI_WEBHOOK_PUBLIC_URL is not set on the orchestrator) with a hint to set it. kici-admin source list prints the URL again under each GitHub source (ingress: …).

The private key and webhook secret are stored encrypted in the orchestrator database under KICI_SECRET_KEY; no restart needed — the orchestrator accepts webhooks from this App immediately.

Secret input modes (for --private-key and --webhook-secret):

ModeSyntaxExample
Direct value--private-key <value>--webhook-secret mysecret
File (@ prefix)--private-key @<path>--private-key @/path/to/key.pem
Environment variable--from-env <var>--from-env GITHUB_PRIVATE_KEY
Standard input--stdincat key.pem | kici-admin source add github --stdin ...

Use @file for private keys — it reads the full PEM including newlines without quoting pitfalls.

To list and inspect:

Terminal window
kici-admin source list # All configured sources
kici-admin source get-webhook-secret github:12345 # Fetch the secret (for debugging)

For the full CLI reference see the source section of the kici-admin CLI reference.

Every GitHub App source has routing key github:<appId>. It’s the identifier every other KiCI surface uses to talk about the source:

  • kici-admin source update github:<appId> ... for rotation / updates
  • kici-admin source remove github:<appId> to decommission
  • kici-admin org-settings global-workflows ... --org <orgId> [--source github:<appId>] for policy (org-scoped row, optional per-entry source qualifier)
  • The orchestrator’s source records and event-log entries key on github:<appId>; org-level settings key on customer_id (one row per org)

If you install the same App across multiple KiCI orgs, each org has its own source record and the orchestrator looks up the right one by combining the URL’s <orgId> with the App ID from the X-GitHub-Hook-Installation-Target-ID header.

For a GitHub App source, GitHub is the source of truth for the displayed name. --name is only the name you request when the App is created; GitHub assigns the final display name and a URL-safe slug (my-org → my-org-1 if the name was taken). KiCI captures both at creation and shows them in the dashboard Sources tab — the display name prominently, with the slug as dimmed secondary text.

If you later rename the App in GitHub’s UI, KiCI keeps the displayed name in sync two ways:

  • Automatically, on a daily schedule. The orchestrator re-reads each GitHub source’s name + slug from GitHub and updates the dashboard if they changed. The interval is configurable via KICI_GITHUB_APP_NAME_REFRESH_INTERVAL_MS (default 24h).

  • On demand, with source refresh:

    Terminal window
    kici-admin source refresh github:<appId> # one source
    kici-admin source refresh --all # every GitHub source

    It prints old → new for any name or slug that changed, and is a no-op when GitHub already matches what KiCI has stored. Non-GitHub routing keys are rejected — name/slug sync applies only to GitHub App sources.

source refresh also compares the App with what KiCI needs. It warns when the App lacks a permission or an event (for example the Issues permission or the Issue comment event), and lists the installations that have not accepted a new permission yet. --json carries the same findings as missingEvents, missingPermissions and installationsPendingApproval. The daily refresh logs a warning for each App with a gap.

By default the manifest flow bakes the URL the orchestrator resolves for its mode (see One-click setup). If you run your own ingress and want GitHub to deliver events to it instead, pass --webhook-url when creating the App:

Terminal window
kici-admin source add github --manifest --name my-org \
--webhook-url https://hooks.my-infra.example/github

The supplied URL must be an absolute https:// URL; it is written into the App’s webhook configuration verbatim. This is the operator asserting “I own webhook delivery”: KiCI adds no ingress at this URL and does not receive events there — your own infrastructure is responsible for accepting GitHub’s deliveries and routing them onward.

A GitHub App source opts in to org-wide global workflows using the org-scoped settings row. Pass --org <orgId> to select the row; on *-add mutators, pass --source github:<appId> when you want a list entry pinned to this specific App rather than applying to any source in the org:

Terminal window
# Enable global workflows cluster-wide (the master switch is fleet-wide, held by the operator)
kici-admin cluster-settings set --global-workflows-enabled true
# Allow the listed repo as an author for any source in the org
kici-admin org-settings global-workflows allow-add 'my-org/ci-workflows/*' \
--org <orgId>
# Allow the listed repo as an author only when authored on this App
kici-admin org-settings global-workflows allow-add 'my-org/ci-workflows/*' \
--org <orgId> --source github:12345
# Deny events from untrusted repos delivered on this App
kici-admin org-settings global-workflows deny-add 'my-org/contrib/*' \
--org <orgId> --source github:12345

Global workflows authored in a GitHub App repo can dispatch against events from universal-git sources in the same org, and vice versa, with each clone using its own source’s credentials. See Global workflows for the policy model and cross-source dispatch contract.

Once registered, the App’s Check-runs permission lets KiCI post enriched Check runs:

  • kici/{workflowName} — overall pass/fail for the workflow
  • kici/{workflowName}/job/{jobName} — per-job detail with step progress
  • kici/{workflowName}/setup — (optional) build / dependency-install check

Step progress, log tails, and source-location annotations are all driven by the orchestrator’s reporting module; no workflow configuration is required beyond installing the App with the checks: write permission.

Each check run’s conclusion follows the job’s or workflow’s status:

StatusCheck conclusion
successsuccess
failed, drift_dropped, unroutablefailure
cancelledcancelled
timed_out_staletimed_out
skippedskipped

GitHub accepts a skipped check as a passed required check. A job that a rule skipped, or that a needs edge skipped, therefore does not block a pull request. To block a pull request when any job of a workflow fails, make the workflow check kici/{workflowName} required, not only the per-job checks.

Check runs are keyed to the head commit SHA, so they surface whether or not a pull request exists: after a push you see the pass/fail directly on the commit (a red ✗ / green ✓ next to the SHA in GitHub’s commit list and on the commit page), and the same checks roll up into the Checks tab of any pull request that later includes the commit. A failing run is therefore visible in GitHub itself without opening the KiCI dashboard.

The Details link of each check run opens the run in the KiCI dashboard. The workflow, setup and job checks of one run all open the same run page. An orchestrator connected to the KiCI Platform gets the dashboard address from the Platform, so it needs no configuration. To send reviewers to a different address, set KICI_DASHBOARD_URL on the orchestrator (see the orchestrator configuration reference). An orchestrator in independent mode posts check runs without a Details link.

For architecture details see GitHub checks architecture.

A /kici approve or /kici reject comment on a pull request releases or rejects a security hold (see CI security). GitHub sends each comment to KiCI as an issue_comment event. An App can subscribe to that event only when it has read access to the Issues repository permission. The one-click setup requests both. A workflow with a comment() trigger needs the same subscription.

Enable comment commands on an existing App

Section titled “Enable comment commands on an existing App”

Open the App’s Settings -> Developer settings -> GitHub Apps -> (your App) -> Edit -> Permissions & events. For an org-owned App, start from the org’s Settings page. If Repository permissions -> Issues is set to No access, or Subscribe to events -> Issue comment is clear, the App sends no comments to KiCI. To fix this:

  1. Set Repository permissions -> Issues to Read-only.
  2. Under Subscribe to events, select Issue comment.
  3. Click Save changes.
  4. Accept the new permission on every installation. GitHub emails the owner of each account where the App is installed, and the installation’s Configure page shows a request to review the new permissions. GitHub does not apply the permission to an installation until its owner accepts it, so the repos of that installation send no comments until then.
  5. Run kici-admin source refresh github:<appId>. It warns while the App still lacks the Issues permission or the Issue comment event, and lists each installation that has not accepted the permission yet.

The orchestrator needs no change: it already handles issue_comment deliveries. To confirm, post a comment on a pull request in an installed repo and look for an issue_comment delivery under the App’s Advanced -> Recent Deliveries.

  1. Generate a new random hex: openssl rand -hex 32.

  2. Update GitHub: App settings -> Webhook -> Webhook secret. GitHub will sign new deliveries with this immediately.

  3. Update the orchestrator:

    Terminal window
    kici-admin source update github:12345 --webhook-secret <new-secret>

    The orchestrator verifies signatures against every cached secret during a dual-secret window, so brief mismatches during rotation don’t drop deliveries. The HMAC verifier iterates over all stored secrets for the routing key.

  1. In GitHub’s App settings click Generate a private key — this does not revoke existing keys. Download the new .pem.

  2. Push it to the orchestrator:

    Terminal window
    kici-admin source update github:12345 --private-key @/path/to/new-key.pem
  3. After confirming clones work on the new key, delete the old key from GitHub’s App settings.

Terminal window
kici-admin source remove github:12345

After removal the routing-key row and its secrets are purged; GitHub deliveries to the endpoint will be rejected as “Unknown routing key”. Uninstall the App from GitHub’s side separately.

Webhook hits the endpoint but KiCI replies 404 Unknown organization. The <orgId> segment of the webhook URL doesn’t match the org that owns the source. Check the URL registered in App settings -> Webhook against kici-admin source list.

Webhook hits the endpoint but KiCI replies 401 Invalid signature. The webhook secret in the App settings doesn’t match the one stored with the source. Rotate it via the steps above.

Webhook hits the endpoint but KiCI replies 400 Missing GitHub App target headers. The request isn’t actually from a GitHub App (missing X-GitHub-Hook-Installation-Target-Type: integration + X-GitHub-Hook-Installation-Target-ID). If you’re test-firing a webhook, use the App’s Recent Deliveries tab on GitHub to re-send a real one.

GitHub’s Recent Deliveries show 409 OBSERVE_ONLY_SOURCE. The App still points at the hosted Platform, but the orchestrator that serves the source runs in observed mode and takes deliveries only on its own URL. Set the App’s webhook URL to the URL kici-admin source list prints. See An App still pointed at the hosted Platform.

Webhook arrives but no run fires. The orchestrator accepted the webhook but no workflow registration matched. Causes (in order of likelihood): the repo isn’t registered with the orchestrator yet (push a commit that touches .kici/kici.lock.json first), the event type isn’t one the workflow’s triggers list, or global_workflow_denied_repos filtered out the source repo. Check kici-admin event-log list --routing-key github:12345 and the orchestrator logs for no registrations for event.

Clone fails with 401 / 403. The installation token minted from the App private key was refused. Usually means the App was uninstalled from the repo, or the private key on the orchestrator no longer matches the one GitHub knows about (rotate it).

Check runs don’t appear on pull requests. The App is missing the checks: write permission or wasn’t installed on the target repo. Re-request permissions in App settings -> Permissions & events (GitHub will prompt installers to accept the new scope on next visit) and confirm the App is installed on that repo.

A /kici approve comment has no effect. Look under the App’s Advanced -> Recent Deliveries for an issue_comment delivery. If there is none, the App does not have the Issues permission or the Issue comment subscription, or the installation has not accepted the permission yet. See Enable comment commands on an existing App. If the delivery is there, the commenter needs a linked GitHub identity and ci_trust:write (see Identity linking). A comment acts only on security holds; release a reviewer hold from the dashboard or with kici approve.
