hi,
i am running cnpg in combination with minio on an arm sbc with ubuntu 23.10 and microk8s 1.29.
my cluster is defined as:
apiVersion: postgresql.cnpg.io/v1
kind: Cluster
metadata:
name: postgres13
namespace: postgres
spec:
instances: 3
imageName: ghcr.io/cloudnative-pg/postgresql:13.14-3
bootstrap:
initdb:
postInitSQL:
storage:
size: 5Gi
backup:
barmanObjectStore:
destinationPath: 's3://backups/'
endpointURL: 'http://minio.postgres:9000/'
s3Credentials:
accessKeyId:
name: minio-creds
key: MINIO_ACCESS_KEY
secretAccessKey:
name: minio-creds
key: MINIO_SECRET_KEY
Minio runs in the same namespace:
NAME READY STATUS RESTARTS AGE
minio-547b5c995b-6dwm5 1/1 Running 2 (5h28m ago) 25h
postgres13-1 1/1 Running 0 3h20m
postgres13-2 1/1 Running 0 3h19m
postgres13-3 1/1 Running 0 3h19m
I creates a bucket “backups” in minio.
When I run a backup:
apiVersion: postgresql.cnpg.io/v1
kind: Backup
metadata:
name: postgres13-backup
namespace: postgres
spec:
cluster:
name: postgres13
It gives an error:
