@kapa.ai On airbyte version 0.56.0, temporal isn't able to initialize namespace default, and none of the services can start because they can't connect to temporal

The knowledge sources don't contain specific information about Airbyte version 0.56.0, but the symptoms you're describing — Temporal failing to initialize the

default

namespace and services unable to connect — are a well-known class of issues. Here's what the knowledge sources suggest as potential causes and fixes: Common Causes & Fixes 1. Temporal Pod Not Listening on the Correct Address (Kubernetes/Helm) On dual-stack clusters (e.g., GKE with both IPv4 and IPv6), the Temporal pod may bind to IPv6 while other services try to connect via IPv4. The fix is to force Temporal to bind to its pod IP: [GKE Dual Stack Issue]

set {
  name  = "temporal.extraEnv[0].name"
  value = "BIND_ON_IP"
}

set {
  name  = "temporal.extraEnv[0].valueFrom.fieldRef.fieldPath"
  value = "status.podIP"
}

Or in Helm values YAML:

temporal:
  extraEnv:
    - name: BIND_ON_IP
      valueFrom:
        fieldRef:
          fieldPath: status.podIP

2. Temporal Service Not Reachable (Connection Refused / DEADLINE_EXCEEDED) This can happen when: • The Temporal pod is not yet ready when other services start up — usually resolves on its own after retries. • A firewall or network policy is blocking port

7233

between pods. • The Temporal pod itself is crashing or unhealthy. Steps to diagnose: • Check the Temporal pod logs:

kubectl logs <airbyte-temporal-pod>

• Verify the Temporal pod is running and its service resolves correctly:

kubectl get svc | grep temporal

• Test connectivity from another pod:

kubectl exec -it <server-pod> -- curl airbyte-temporal:7233

3. Docker Compose Deployments If you're using Docker Compose, ensure: • All containers are healthy (not just "Up") • No firewall (e.g.,

firewalld

) is blocking inter-container communication [Docker Compose Issue] 4. Database Migration Issues If you recently upgraded Helm chart versions, a failed or incomplete database migration can cause services to hang or fail to connect properly. [Migration Issue] To help narrow down the root cause, please share: • Your deployment method (Helm/Kubernetes, Docker Compose, abctl) • The Temporal pod logs • Whether this is a fresh install or an upgrade • Your cluster type (single-stack IPv4, dual-stack, etc.) 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.

It's saying waiting for postgresql to start

Sorry @Omree Gal-Oz, I'm not sure what you mean. Please try again. 👋

It's saying waiting for postgresql to start. We're on docker compose @kapa.ai

Based on the knowledge sources, the "Waiting for PostgreSQL to startup" loop in

airbyte-temporal

is a common Docker Compose issue. Here are the most likely causes and fixes: 1. Port 5432 Already in Use The most common cause is another PostgreSQL instance already running on port 5432 on your host machine. The

airbyte-db

container fails to bind to the port, causing Temporal to wait forever. Check for this in your

airbyte-db

logs:

docker-compose logs db

If you see

could not bind IPv4 address "0.0.0.0": Address in use

, you have a port conflict. [Port Conflict Issue] Fix: Stop any local PostgreSQL service running on your host:

sudo systemctl stop postgresql

Then restart Airbyte:

docker-compose down
docker-compose up

2. Snap Version of Docker on Ubuntu If you're on Ubuntu and installed Docker via Snap, AppArmor may be blocking inter-container communication. [Ubuntu Docker Issue] Fix: Remove the Snap version and reinstall via `apt`:

sudo snap remove docker
sudo apt-get install docker-compose

3. Misconfigured External Database If you've configured an external database in your

.env

file, double-check that

DATABASE_HOST

,

DATABASE_PORT

,

DATABASE_USER

,

DATABASE_PASSWORD

, and

DATABASE_URL

are all correct and that the database is reachable from within the Docker network. [External DB Config] To confirm the root cause, run:

docker-compose logs db

and share what you see — that will pinpoint whether it's a port conflict, a startup failure, or a configuration issue. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
