pgbackrest container can't start when running on slave pod

[lonelyleaf]

When using backup featuer in helm chart,only the master pod's pgbackrest container can
start up , the log of slave container is like below:

ERROR: [027]: primary database not found
       HINT: check indexed pg-path/pg-host configurations
2019-12-23 06:34:28 - bootstrap - Creating pgBackrest stanza
INFO: stanza-create command begin 2.19: --compress-level=3 --config=/etc/pgbackrest/pgbackrest.conf --log-level-stderr=info --pg1-path=/var/lib/postgresql/data --pg1-port=5432 --pg1-socket-path=/var/run/postgresql --repo1-cipher-type=none --repo1-path=/timescaledb-single/pg-test --repo1-s3-bucket=timescaledb-backup --repo1-s3-endpoint=minio.haorun.win --repo1-s3-key=<redacted> --repo1-s3-key-secret=<redacted> --repo1-s3-region=us-east-2 --no-repo1-s3-verify-tls --repo1-type=s3 --stanza=poddb
ERROR: [056]: unable to find primary cluster - cannot proceed
INFO: stanza-create command end: aborted with exception [056]

I checked the issues of pgbackrest pgbackrest/pgbackrest#878, so by default only the master db can be backup.

But in a statefuleset ,when pgbackrest fail to start the service timescaledb-single-replica won't have available endpoints,causing conneting to slave is imposiable

@lonelyleaf We fixed this in the latest release (1.5.1), could you verify that it is solved for you now?

It is still not solved (0.9.0):
