AkurAI Build

A small Git-native CI/CD system built with pinned Rust 1.97: one Rust binary for repositories, pipelines, Docker/native jobs, configurable Titan build workers, build matrices, logs, artifacts, protected deployments, webhooks, filterable CLI/API queries, and a responsive MiniJinja workbench.

It keeps the useful center of Jenkins, GitLab CI, GoCD, Concourse, and Woodpecker with a minimal authenticated Smart HTTP Git host, but without plugin markets, cluster control planes, or frontend frameworks.

Foundation

AkurAI Build starts from Bunfork's proven shape:

• Rust single binary
• encrypted SQLCipher state and ordered migrations
• bounded Axum/Hyper HTTP serving
• MiniJinja templates and dependency-free Ponytail UI
• strict CSP, constant-time tokens, protected files, and hardened systemd
• digest-recorded artifacts and rollback-oriented deployment

Bunfork remains a supported artifact target; AkurAI Build replaces its unrelated vector/demo application surface with CI/CD.

All mutations use the maintained entrypoint:

./deploy.sh bootstrap
./deploy.sh check
./deploy.sh deploy
./deploy.sh vhost
./deploy.sh status

Running it outside Titan forwards to Titan. deploy checks, release-builds, retains the prior binary, creates protected keys when absent, migrates transactionally, installs the Pi skill, and restarts the hardened system service under olafurbui with only the Docker supplementary group.

Pipeline

Commit .akurai.yml:

version: 1
jobs:
  - name: test
    image: oven/bun:1.3
    network: true
    run:
      - bun install --frozen-lockfile
      - bun test
    matrix:
      platform: [linux/amd64, linux/arm64]
    cache: [.bun]

  - name: package
    needs: [test]
    image: oven/bun:1.3
    run: bun build src/index.ts --compile --outfile dist/app
    artifacts: [dist/**]

  - name: deploy
    needs: [package]
    executor: native
    environment: production
    approval: true
    branches: [main]
    secrets: [DEPLOY_TOKEN]
    run: ./deploy.sh dist/app

Jobs default to depending on the previous job; set needs: [] for an independent root. Caches are isolated by registered repository and shared by its jobs. Matrix axes expand to at most 32 variants and become AKURAI_MATRIX_<AXIS> variables. platform also selects Docker's --platform.

Docker jobs run with dropped capabilities, no-new-privileges, fixed CPU/memory/PID limits, a read-only root, writable workspace/tmp, host UID/GID, and no network unless network: true. Linux amd64/arm64 variants use Titan Docker with pinned tonistiigi/binfmt:qemu-v10.2.3-68 QEMU registration, rechecked by every deploy. Native jobs are disabled unless the repository is trusted and AKURAI_ALLOW_NATIVE=1 is set.

Declared secrets resolve only from AKURAI_SECRET_<NAME>, are omitted from Docker arguments, and are exact-value-redacted from retained logs. Repository writers with secret-bearing jobs are privileged because build code can intentionally transform or exfiltrate a secret.

CLI for people and agents

Every query and mutation command emits one JSON envelope. mcp is the newline-delimited JSON-RPC stdio transport.

./deploy.sh cli doctor
./deploy.sh cli repo add app https://github.com/org/app.git --branch main
./deploy.sh cli repo host app /home/olafurbui/Projects/app --branch main
./deploy.sh cli repo sync app /home/olafurbui/Projects/app
./deploy.sh cli repo list --search app --visibility private
./deploy.sh cli run app --git-ref main
./deploy.sh cli runs --repo app,worker --status failed,interrupted --trigger manual,webhook --search compiler --limit 20
./deploy.sh cli show 42
./deploy.sh cli wait 42 --timeout 3600
./deploy.sh cli logs 42 --failed
./deploy.sh cli retry 42
./deploy.sh cli promote 42 production
./deploy.sh cli artifact get 7 ./artifact.bin
./deploy.sh cli workers

The bundled skills/akurai-build/SKILL.md makes these the stable operating surface for BunFast and OMP agents. repo host creates a bare mirror below the protected AkurAI Build data root and atomically switches the CI registration to it; repo sync refreshes that mirror from its trusted Titan checkout. repo list filters by text and visibility. runs accepts comma-separated --repo, --status, and --trigger filters plus exact --git-ref, free-text --search, bounded --limit, and --offset; /api/state exposes the same run query shape. Agents must verify persisted succeeded states rather than infer success from process output.

MCP query server

akurai mcp serves four read-only MCP tools over stdio: akurai_repositories, akurai_runs, akurai_run, and akurai_workers. Repository and run tools accept the same composable filters as the CLI, including a string, comma-separated string, or array for multi-value run filters. Configure an MCP client to launch the maintained entrypoint:

{
  "mcpServers": {
    "akurai-build": {
      "command": "/home/olafurbui/Projects/AkurAI-Build/deploy.sh",
      "args": ["cli", "mcp"]
    }
  }
}

Hosted Git

Hosted repositories are available at https://akurai-build.olibuijr.com/git/<name>.git. Smart HTTP reads and writes require the existing AkurAI Build bearer token; the token must be supplied through a protected credential helper or maintained command, never a URL, command argument, source file, or log. CI uses the local bare mirror directly, so builds do not depend on public DNS or the edge proxy.

Git webhooks

Use:

POST https://akurai-builds.olibuijr.com/api/hooks/<repository-name>

Supported authentication:

• GitHub X-Hub-Signature-256
• Gitea X-Gitea-Signature
• GitLab X-Gitlab-Token

The secret is the protected webhook.token; do not expose it in commands or documentation. Push payloads supply ref and the immutable commit. Manual/UI/API mutations require the separate bearer API token.

State and recovery

• A run stores its resolved immutable commit before reading .akurai.yml.
• Jobs execute fail-fast in dependency order; all variants of a dependency must succeed.
• Artifacts are bounded, SHA-256 recorded, copied without symlinks/traversal, and served only after authorization.
• A protected deployment records the exact upstream artifact IDs and digests before execution.
• Every Titan worker persists its status, capacity, heartbeat, current run, and completed-run count; restart recovery marks stale workers offline before registering the configured pool.
• systemd restarts controller failures; deploy.sh rollback restores the prior binary.

Run evidence is the system's operational knowledge. It supports debugging and safe iteration without allowing unreviewed self-modifying code.

Limits kept intentionally

The first release uses one Titan scheduler with a configurable local worker pool and SQLite. Each worker owns one run at a time; jobs inside a run remain dependency-ordered and isolated. Linux container matrices are complete; native Windows/macOS and remote Windows-container builds wait for a signed artifact-streaming agent protocol rather than pretending remote bind mounts are portable. Object storage, provider commit-status adapters, and role-based multi-user accounts are deferred—not stubbed.

Development

./deploy.sh lock       # only after reviewed dependency edits
./deploy.sh check
./deploy.sh docker-smoke
./deploy.sh publish "change summary"
./deploy.sh deploy

check runs formatting, Clippy with warnings denied, and all locked tests. Direct deployment or publication commands are outside the operating contract.
