Troubleshooting
Designer returns 503
Section titled “Designer returns 503”Cause — almost always Traefik returns 503 because the designer container is restarting (deploy in progress, OOM kill, crashed boot).
Diagnose:
ssh <host> 'docker ps -a --format "{{.Names}}\t{{.Status}}" | grep pipebase-designer'ssh <host> 'docker logs --tail 100 $(docker ps --format "{{.Names}}" | grep pipebase-designer)'If the container is Restarting, look at the last lines of the log
for the boot error. Common ones:
PIPEBASE_DEPLOY_TOKEN must be set— missing env var. Coolify env config drifted.EADDRINUSE :::3000— leftover bind from a partial deploy. Kill orphan containers.
Flow stuck “Deploying…”
Section titled “Flow stuck “Deploying…””Diagnose:
ssh <host> 'docker logs --tail 200 $(docker ps --format "{{.Names}}" | grep pipebase-runtime) 2>&1 | grep -i "PUT\|error\|<flow-id>"'The runtime logs every PUT /_api/flows/:id plus its outcome. If you
don’t see your flow id, the designer never reached the runtime — check
PIPEBASE_RUNTIME_URL and the deploy token.
If the runtime logs an error parsing the YAML, the deploy was rejected (400). The designer should surface the error in a toast; if it doesn’t, that’s a designer bug — file an issue with the toast text.
”Failed to obtain certificate” (Let’s Encrypt)
Section titled “”Failed to obtain certificate” (Let’s Encrypt)”See TLS. Almost always:
- DNS hasn’t propagated, OR
- Port 80 isn’t reachable from the public internet, OR
- Let’s Encrypt rate-limited you (5 failed validations / hour / hostname)
Runtime container restarts in a loop
Section titled “Runtime container restarts in a loop”Cause — usually one bad YAML in /opt/pipebase/routes/ that fails
to parse + crashes startup.
Pre-805c243 runtime: that bug existed and required SSH cleanup.
Post-805c243 runtime (everything ≥ v0.4): fail-soft is in place
— a bad YAML logs a WARN and the rest of the routes load fine. If
you’re seeing crash loops on a recent runtime, the problem is somewhere
else (OOM, port conflict). Check docker inspect exit code.
Coolify deploy fails with “exit status 1” / “failed to compute checksum”
Section titled “Coolify deploy fails with “exit status 1” / “failed to compute checksum””The pnpm/Java build inside the Dockerfile produced no output. Usually because:
- A
pnpm --filter @pipebase/<name>ran but no package matched (the catastrophic version of the rebrand bug) - A
tsc --noEmitfailed inside the build stage and the&&chain short-circuited
Look at the [stdout] lines in the Coolify deploy log right before the
error — the actual TS / pnpm complaint is in there. The trailing
“failed to execute bake” message is just the orchestrator’s wrapper.
Cookbook to inspect a failed Coolify deploy:
ssh <host> 'docker exec coolify-db psql -U coolify -d coolify -tAc "SELECT logs FROM application_deployment_queues WHERE id=<deploy-id>;"' \ > /tmp/deploy.logpython -c "import jsonwith open('/tmp/deploy.log') as f: data = f.read()for x in json.loads(data): print('[' + (x.get('type') or '?')[:6] + ']', (x.get('output') or '').rstrip()[:200])"Traefik routes the wrong container
Section titled “Traefik routes the wrong container”Symptom: a flow you just deployed via the UI returns 404 from the public URL.
Cause — orphan containers. Coolify leaves the old generation
attached to the network during deploys; both register the same
Host(...) rule and Traefik load-balances between them.
Fix:
ssh <host> 'for s in pipebase-runtime pipebase-designer pipebase-kafka pipebase-pulsar; do keep=$(docker ps --format "{{.Names}} {{.CreatedAt}}" | grep "^$s-" | sort -k2 | tail -1 | cut -d" " -f1) for c in $(docker ps --format "{{.Names}}" | grep "^$s-" | grep -v "^$keep$"); do echo "stopping orphan $c"; docker stop "$c" && docker rm "$c" donedone'Then redeploy the affected flow.
