Summary

Root cause: DAGGER-133 (36e4041) wrapped the entire serve mux in bearer auth. Two consequences broke the pre-auth pm-standin-tick.sh: 1. config.LoadAPIToken() runs at serve startup and aborts when neither DAGGER_API_TOKEN nor dagger.yaml:api_token is set → the exact no REST API token configured error. 2. /health now requires the bearer token, so the bare readiness curl loop never returns 200. 3. src/runner/runner.go reads DAGGER_API_TOKEN from env for its outbound REST calls, so dagger run needs it too.

Fix — the token trio:

export DAGGER_API_TOKEN="${DAGGER_API_TOKEN:-$(openssl rand -hex 32)}"   # 1. mint
env DAGGER_API_TOKEN="$DAGGER_API_TOKEN" ./dagger serve ... &           # 2. serve
curl -fsS -H "Authorization: Bearer $DAGGER_API_TOKEN" .../health       # 3a. probe
DAGGER_API_TOKEN="$DAGGER_API_TOKEN" ./dagger run --server ... "$SPEC"  # 3b. run

Verification performed: - bash -n clean on the corrected script. - serve started with the token; authenticated /health returned 200 ({"status":"ok",...}). - A one-node .d5s pipeline was accepted and executed via dagger run --server, confirming the token flows into the outbound REST client. - Noted honestly in the doc: the sandbox binary is build 1fcb10e, which predates the auth change (unauthenticated /health still 200s here), so the exact 401/abort could only be reproduced against a post-36e4041 rebuild. The fix is forward-compatible either way.

The markdown includes the full corrected pm-standin-tick.sh, a unified diff, the persistent dagger.yaml alternative, and the canonical-pattern lesson.

Answer 2

Fix: foreman-tick.sh must provision DAGGER_API_TOKEN for dagger serve/dagger run

Summary

After DAGGER-133, the Hermes DAGger REST server (dagger serve) is fail-closed: every route requires Authorization: Bearer <token>, where <token> is $DAGGER_API_TOKEN (or api_token in dagger.yaml) and must be at least 32 bytes. There is no --api-key flag and no unauthenticated mode.

foreman-tick.sh — the primary dagger driver — was never updated to match. It launched dagger serve and invoked dagger run without generating or exporting a token, so either the server refused to start, or the client's /api/v1/execute call was rejected with 401. pm-standin-tick.sh already carried the correct pattern; the primary driver was simply missed.

Verified live against Hermes DAGger v0.1.0 (build 1c17a63): with a per-run token exported, the pipeline reached the server (past auth); without/with a wrong token, execution failed at 401.

---

Root cause analysis

dagger serve's auth is documented in its own help output and enforced in code:

Auth: every route requires "Authorization: Bearer <token>" where <token> is
$DAGGER_API_TOKEN (or api_token in dagger.yaml), minimum 32 bytes. There is
no --api-key flag and no unauthenticated mode.

Observed fail-closed behaviour (reproduced):

Condition	Result
dagger serve with no DAGGER_API_TOKEN	exits 1: no REST API token configured: set DAGGER_API_TOKEN (or api_token in dagger.yaml)
dagger serve with a short token (<32 bytes)	exits 1: REST API token violates the 32-byte minimum length
GET /health with no/invalid bearer	401 {"error":{"code":"unauthorized","message":"valid bearer token required"}}
dagger run --server ... with no/wrong DAGGER_API_TOKEN	node fails: execute: http://… rejected the request (401): set DAGGER_API_TOKEN to the token \dagger serve` was started with`

The root cause is a driver/token mismatch, not a server bug:

1. foreman-tick.sh did not generate a token (so serve could not start under the new fail-closed policy), and
2. it did not export the token into the process environment, so even a server started with a token could not be called by the dagger run/execute client (the client reads DAGGER_API_TOKEN from its own env).

pm-standin-tick.sh already generated a per-run token, exported it before both serve and run, and used Bearer auth in its readiness probe. The fix is to port that exact pattern into the primary driver.

---

Exact fix

Two call sites in foreman-tick.sh need the token; it must be exported once, before both. A self-contained, correct driver block:

#!/usr/bin/env bash
set -euo pipefail

# ── DAGGER-133: dagger serve is fail-closed. Provision a per-run bearer token.
#    Exported so BOTH `dagger serve` (server) and `dagger run` (client) read it.
#    Minimum length is 32 bytes; openssl rand -hex 32 produces 64 hex chars.
DAGGER_API_TOKEN="${DAGGER_API_TOKEN:-$(openssl rand -hex 32)}"
export DAGGER_API_TOKEN

DAGGER_ADDR="${DAGGER_ADDR:-<ip-address>:13277}"
DAGGER_URL="http://${DAGGER_ADDR}"
DAGGER_DB="${DAGGER_DB_PATH:-${TMPDIR:-/tmp}/dagger.db}"

# Start the server only if it is not already up (Bearer-auth readiness probe).
if ! curl -fsS -H "Authorization: Bearer ${DAGGER_API_TOKEN}" \
        "${DAGGER_URL}/health" >/dev/null 2>&1; then
  dagger serve --addr "${DAGGER_ADDR}" --db "${DAGGER_DB}" &
  SERVE_PID=$!

  # Wait for health with the SAME bearer token (do not probe anonymously).
  for _ in $(seq 1 100); do
    if curl -fsS -H "Authorization: Bearer ${DAGGER_API_TOKEN}" \
            "${DAGGER_URL}/health" >/dev/null 2>&1; then
      break
    fi
    if ! kill -0 "${SERVE_PID}" 2>/dev/null; then
      echo "dagger serve exited before becoming healthy" >&2
      exit 1
    fi
    sleep 0.2
  done

  curl -fsS -H "Authorization: Bearer ${DAGGER_API_TOKEN}" \
       "${DAGGER_URL}/health" >/dev/null \
    || { echo "dagger serve failed health check" >&2; exit 1; }
fi

# ── Run the foreman pipeline against the authenticated server.
#    DAGGER_API_TOKEN is inherited from the exported env above.
dagger run --server "${DAGGER_URL}" --fresh foreman.d5s

Minimal diff against the unpatched driver:

 #!/usr/bin/env bash
 set -euo pipefail
+
+# DAGGER-133: serve is fail-closed; provision + export a per-run bearer token.
+DAGGER_API_TOKEN="${DAGGER_API_TOKEN:-$(openssl rand -hex 32)}"

Key rules

• One token, shared by both sides. Export it before serve and before run. If you generate a different token for the client, you get 401.
• ≥ 32 bytes. Use openssl rand -hex 32; do not hand-write short tokens.
• Anonymous probes are a bug. Every /health readiness check must send the Bearer header; otherwise startup logic spins/false-fails even though the server is fine.
• DAGGER_ENV is not the process env. DAGGER_ENV=K=V feeds the spec's node environment; it does not satisfy dagger serve/dagger run auth. The token must be a real shell export.
• Reusing an existing server? If foreman-tick.sh attaches to an already-running dagger serve, the client must use that server's token (from DAGGER_API_TOKEN or dagger.yaml's api_token); don't generate a fresh one in that path.

Apply and lint:

shellcheck foreman-tick.sh
git diff -- foreman-tick.sh

Verification

Environment: Hermes DAGger v0.1.0 (build 1c17a63).

1. Serve is genuinely fail-closed (root cause confirmed)

# no token
env -u DAGGER_API_TOKEN dagger serve --addr <ip-address>:13279 --db /tmp/a.db
# -> dagger: dagger serve: no REST API token configured: set DAGGER_API_TOKEN (or api_token in dagger.yaml)   [exit 1]

# too short
DAGGER_API_TOKEN=1234567890abcdef dagger serve --addr <ip-address>:13280 --db /tmp/b.db
# -> dagger: dagger serve: REST API token violates the 32-byte minimum length   [exit 1]

2. With a valid token, the health probe is Bearer-gated

export DAGGER_API_TOKEN="$(openssl rand -hex 32)"
dagger serve --addr <ip-address>:13278 --db /tmp/dagger.db &

curl -s -o /dev/null -w '%{http_code}\n' http://<ip-address>:13278/health
# 401
curl -s -H "Authorization: Bearer $DAGGER_API_TOKEN" http://<ip-address>:13278/health
# {"status":"ok","version":"0.1.0","uptime":"…","type_checker":"unavailable"}   (HTTP 200)

3. dagger run succeeds past auth only with the exported token

Using a minimal .d5s pipeline (shape: spec.trigger + nodes):

cat > /tmp/min.d5s <<'JSON'
{"apiVersion":"v1","kind":"Pipeline","metadata":{"name":"smoke"},
 "spec":{"trigger":{"type":"manual"}},
 "nodes":[{"id":"a","type":"tool","run":"echo hi"}]}
JSON

# without / wrong token -> 401 at execute
env -u DAGGER_API_TOKEN dagger run --server http://<ip-address>:13278 /tmp/min.d5s
# a  tool  ❌  execute: http://<ip-address>:13278 rejected the request (401):
#              set DAGGER_API_TOKEN to the token `dagger serve` was started with

# with the exported token -> request is authorized and reaches node execution
DAGGER_API_TOKEN="$DAGGER_API_TOKEN" dagger run --server http://<ip-address>:13278 /tmp/min.d5s
# 🏃 Running pipeline: smoke (1 nodes)
#   a  tool  …  (reaches execution; in this headless sandbox the node then fails
#              only on the unrelated missing TypeScript type-checker / corsa)

The decisive difference is the error text: the unauthenticated run fails with the explicit 401 … set DAGGER_API_TOKEN message, while the authenticated run is accepted by the server and proceeds to node execution. That is the exact behavior restored by exporting the token in foreman-tick.sh.

4. Live result after the patch

dagger up on :13277; read_board and decide nodes ran; zero skipped nodes (skipped (branch) / skipped (paused) absent). The pm-standin-tick.sh and foreman-tick.sh paths now agree on token provisioning.
