[bitnami/seaweedfs] Waiting for database init container not compatible with Istio

[wkbrd]

Name and Version

bitnami/seaweedfs 4.2.0

What architecture are you using?

amd64

What steps will reproduce the bug?

With Istio configured to inject sidecars in containers for the namespace that contains the database and seaweedfs (same namespace), the wait-for-db init container within the seaweedfs-filer pod does not complete.

Failed with Istio 1.22.3

The postgresql database is installed using the bitnami postgresql chart and is fully running in advance and has the Istio sidecar attached.

The seaweedfs-filer has the wait-for-db pod continuing to fail to connect since the istio-proxy (sidecar) is not yet running. It is in PodInitializing. I expect it will remain in this state until the wait-for-db init container completes.

Are you using any custom parameters or values?

Using external database settings to connect to a Postgres that is installed first with the seaweedfs table definition.

What is the expected behavior?

seaweedfs-filer pod's wait-for-db is able to connect to postgresql and then the pod fully comes up.

What do you see instead?

wait-for-db remains in 'Waiting' stage within Kubernetes and then ultimately restarts.

Log for wait-for-db:
postgresql 14:54:34.49 INFO ==> Waiting for host seaweedfs-postgres-postgresql.<truncated> 2025-01-02T14:55:34.651244546Z postgresql 14:55:34.65 ERROR ==> Database not ready

Additional information

The same chart versions/configuration without Istio works properly and seaweedfs fully comes up.

Tested from a clean Helm install in both positive and negative configurations described.
