[pgpool-general: 7880] PgPool in Kubernetes issues

[Nikolay Mastilo (HM)]

Hello All,

Our PgPool runs in Kubernetes and its start comes with a lot of error 
messages:

2021-11-17 12:20:07: pid 20: ERROR:  unable to read data from DB node 0
2021-11-17 12:20:07: pid 20: DETAIL:  EOF encountered with backend
2021-11-17 12:20:07: pid 20: LOG:  find_primary_node: 
make_persistent_db_connection_noerror failed on node 0
2021-11-17 12:20:07: pid 20: ERROR:  unable to read data from DB node 1
2021-11-17 12:20:07: pid 20: DETAIL:  EOF encountered with backend
2021-11-17 12:20:07: pid 20: LOG:  find_primary_node: 
make_persistent_db_connection_noerror failed on node 1

This takes exactly 5 minutes.

Kubernetes PgPool pod run docker image pgpool:4.2.2

Could anyone tell what's wrong and how avoid these errors?

Because these errors appear only if PgPool starts in Kubernetes.

If I run it outside of Kubernetes, such errors do not appear and the 
PgPool docker container with image  pgpool:4.2.2 starts instantly.

Thanks in advance.
