I'm trying to install postgresql via helm. I'm not overriding any settings, but when I try to connect, I get a "password authentication failed" error:
$ helm install goatsnap-postgres stable/postgresql
NAME: goatsnap-postgres
LAST DEPLOYED: Mon Jan 27 12:44:22 2020
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
** Please be patient while the chart is being deployed **
PostgreSQL can be accessed via port 5432 on the following DNS name from within your cluster:
goatsnap-postgres-postgresql.default.svc.cluster.local - Read/Write connection
To get the password for "postgres" run:
export POSTGRES_PASSWORD=$(kubectl get secret --namespace default goatsnap-postgres-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
To connect to your database run the following command:
kubectl run goatsnap-postgres-postgresql-client --rm --tty -i --restart='Never' --namespace default --image docker.io/bitnami/postgresql:11.6.0-debian-9-r0 --env="PGPASSWORD=$POSTGRES_PASSWORD" --command -- psql --host goatsnap-postgres-postgresql -U postgres -d postgres -p 5432
To connect to your database from outside the cluster execute the following commands:
kubectl port-forward --namespace default svc/goatsnap-postgres-postgresql 5432:5432 &
PGPASSWORD="$POSTGRES_PASSWORD" psql --host 127.0.0.1 -U postgres -d postgres -p 5432
$ kubectl get secret --namespace default goatsnap-postgres-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode

$ kubectl run goatsnap-postgres-postgresql-client --rm --tty -i --restart='Never' --namespace default --image docker.io/bitnami/postgresql:11.6.0-debian-9-r0 --env="PGPASSWORD=DCsSy0s8hM" --command -- psql --host goatsnap-postgres-postgresql -U postgres -d postgres -p 5432
psql: FATAL: password authentication failed for user "postgres"
pod "goatsnap-postgres-postgresql-client" deleted
pod default/goatsnap-postgres-postgresql-client terminated (Error)
I've tried a few other things, all of which get the same error:
- Run
kubectl run [...] bash, launch psql, type the password at the prompt - Run
kubectl port-forward [...], launch psql locally, type the password - Un/re-install the chart a few times
- Use
helm install --set postgresqlPassword=[...], use the explicitly-set password
I'm using OSX 10.15.2, k8s 1.15.5 (via Docker Desktop 2.2.0.0), helm 3.0.0, postgres chart postgresql-7.7.2, postgres 11.6.0
I think I had it working before (although I don't see evidence in my scrollback), and I think I updated Docker Desktop since then, and I think I saw something about a K8s update in the notes for the Docker update. So if I'm remembering all those things correctly, maybe it's related to the k8s update?
