V2.2 not work pgbackrest

PostgreSQL Percona Operator for PostgreSQL
1

Description:

I deploy a cluster where only the master without replicas.
Apparently in this case, a stanza is not created. (???)
In the logs of the operator there are such entries:

time="2023-08-07T10:55:26Z" level=debug msg="command terminated with exit code 31: ERROR: [031]: configuration file contains duplicate options ('repo1-path', 'repo-path') in section '[global]'\n" object="{PostgresCluster pgo pdb e1810128-f1ca-4b34-a3e5-7cf5d488f5ef postgres-operator.crunchydata.com/v1beta1 1478195 }" reason=UnableToCreateStanzas type=Warning version=
time="2023-08-07T10:55:26Z" level=debug msg="reconciled cluster" PostgresCluster=pgo/pdb controller=postgrescluster controllerGroup=postgres-operator.crunchydata.com controllerKind=PostgresCluster name=pdb namespace=pgo reconcileID=be98145c-985d-431e-9f3e-549e8a803757 version=

attempts to make a backup on demand are not successful

Steps to Reproduce:

deploy a cluster where only the master without replicas

Version:

pgo2.2 pgbackrest 2.43

I clarify the situation - we use our own image pg13 which is from the Dockerfile of the corresponding percona repo.
We inserted a COPY of the RPMs we collected with a couple of pg extensions into it. And another command to install these rpm.

Now we noticed that with the native image for pg13 there is a file
/etc/pgbackrest.conf with content

[main]
#pg1-path=/data/db

and with ours we have content like this

[global]
repo-path=/var/lib/pgbackrest

#[main]
#pg-path=/var/lib/pgsql/data

It became clear what was causing the error, but it is not clear why this is happening)
Tried to delete a /etc/pgbackrest.conf file in the Dockerfile

the original error disappeared, but lo and behold a new one appeared

Can someone explain how this works?

Checked pgbackrest versions everywhere 2.43 – Sorry!!! This is not true.

I checked it more carefully - it turned out that version 2.44 is being built into our image - although we did not indicate this anywhere.

Everything was decided like this: (in Dockerfile)

  1. replaced
    percona-pgbackrest
    on
    percona-pgbackrest-1:2.43-1.el8.x86_64
  2. added a line to remove /etc/pgbackrest.conf
    RUN rm -rf /etc/pgbackrest.conf
