PaperClipAI/docker/daytona-runner

Paperclip Daytona runner image

This image is the Paperclip Cloud fleet sandbox image plus a source-built paperclip-runnerd and immutable provider pack. The pack contains Node 24.11, OpenCode 1.18.29, the compiled OpenCode proxy, ACPX 0.13.1 sidecar, qualified ACP agents, and the production lockfile. Its manifest digests each executable bridge and binds the pack to the runner source revision, avoiding artifact upload and npm installation on every fresh lease.

The fleet pins are intentionally copied from paperclip-cloud/fleet-sandbox-image/Dockerfile. Update both definitions together until the fleet base is published as a stable image that this Dockerfile can extend directly.

Build and verify

The fleet image is currently amd64-only because the pinned Cursor and GitHub CLI checksums cover amd64.

content_id="$(pnpm --silent test:e2e:runner:image-id)"
docker buildx build \
  --platform linux/amd64 \
  --build-arg PAPERCLIP_RUNNER_CONTENT_ID="${content_id}" \
  --build-arg PAPERCLIP_RUNNER_SOURCE_REVISION="$(git rev-parse HEAD)" \
  --tag "paperclip-daytona-runner:e2e-content-${content_id}" \
  --load \
  --file docker/daytona-runner/Dockerfile \
  .

docker run --rm --platform linux/amd64 \
  --entrypoint paperclip-runnerd \
  "paperclip-daytona-runner:e2e-content-${content_id}" \
  --build-metadata

The metadata must advertise dial_ws_loopback, dial_wss, and listen_ws. The explicit entrypoint is needed only for this local probe because Daytona's base image uses its own long-running sandbox entrypoint.

test:e2e:runner:image-id hashes the audited Docker build dependency closure, target platform, the immutable Dockerfile syntax-frontend digest, and every immutable FROM reference. It fails before the paid workflow can build when the frontend or a base is not pinned to a sha256 digest. When updating the syntax version, resolve and review its registry digest and update both values in the first Dockerfile line. Git commits that do not change those inputs reuse the same content tag.

PAPERCLIP_RUNNER_SOURCE_REVISION remains the full Git SHA that built the first published copy and is retained as provenance rather than cache identity.

Use in Paperclip

Publish the image to a registry Daytona can pull, or use the environment editor's Configure image flow to produce a Daytona snapshot. Set the environment image to that immutable tag or snapshot. Paperclip probes the sandbox user's PATH for paperclip-runnerd and codex and checks /opt/paperclip-runner/provider-pack for OpenCode and ACPX. It uses the pack only when its complete manifest matches the controller's build-owned pack; otherwise it stages the pack configured by PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH. Remote OpenCode and ACPX never fall back to host-local processes.

Do not promote paperclip-runner-e2e-20260826-v2 for OpenCode or ACPX. Build a new immutable image or snapshot from a clean committed revision and pass that full Git SHA as PAPERCLIP_RUNNER_SOURCE_REVISION.

Do not bake provider credentials, Paperclip bootstrap tickets, or Daytona preview tokens into this image. They remain per-run secret material.

Provider CLI updates are manifest-only changes: repository CI owns the root lockfile. The image build resolves the complete workspace manifest graph before its frozen install, matching CI when a source commit precedes the lockfile bot. The complete resolved lockfile must match PAPERCLIP_RUNNER_LOCK_SHA256 before package installation or lifecycle execution. Review and refresh that digest with source dependency changes; registry-time resolution drift fails closed. Keep one latest stable CLI installation per provider; refresh exact runtime versions and qualification digests together, never install a private older copy or download dependencies when a task starts.
