mahaoyu opened a new issue, #57328:
URL: https://github.com/apache/airflow/issues/57328
### Official Helm Chart version
1.18.0 (latest released)
### Apache Airflow version
3.0.2 (Helm chart appVersion from apache-airflow/airflow 1.18.0)
### Kubernetes Version
Server: v1.30 (k3s, containerd) on Debian 13 Client: v1.30
### Helm Chart configuration
**Chart**: apache-airflow/airflow 1.18.0
**Install cmd:**
```bash
helm upgrade --install airflow apache-airflow/airflow \
--namespace airflow --create-namespace
### Docker Image customizations
_No response_
### What happened
Observed: install times out; pods stuck waiting for Postgres.
kubectl -n airflow get pods
# airflow-postgresql-0 0/1 ImagePullBackOff
# others Init:0/1 waiting on DB
### What you think should happen instead
Why: the Airflow chart depends on Bitnami PostgreSQL subchart 13.2.24:
helm show chart apache-airflow/airflow | grep -A4 '^dependencies'
# name: postgresql
# repository: https://charts.bitnami.com/bitnami
# version: 13.2.24
That subchart’s default image.tag is 16.1.0-debian-11-r15:
helm show values bitnami/postgresql --version 13.2.24 | grep -A1 'image.tag'
# tag: 16.1.0-debian-11-r15
Docker Hub no longer provides that tag (at least can't find it on docker
hub). The registry API shows only latest and sha256 digests:
curl -s
https://registry.hub.docker.com/v2/repositories/bitnami/postgresql/tags \
| jq '.results[].name'
# "latest", "latest-metadata", "sha256-....", ...
Error from pod events (abridged):
Failed to pull image "docker.io/bitnami/postgresql:16.1.0-debian-11-r15":
not found
Back-off pulling image "docker.io/bitnami/postgresql:16.1.0-debian-11-r15"
### How to reproduce
## Minimal repro
**Assumptions**
- Fresh cluster (Kubernetes v1.30.x; containerd).
- Helm 3.10+ on client.
- No custom values; pure defaults.
**Steps**
1) Add repos and confirm dependency:
```bash
helm repo add apache-airflow https://airflow.apache.org
helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update
helm show chart apache-airflow/airflow | grep -A4 '^dependencies'
# -> postgresql subchart version: 13.2.24 (bitnami)
