[root@k8s-master timescale]# helm install tsdb timescaledb-single
NAME: tsdb
LAST DEPLOYED: Wed Dec 8 11:24:45 2021
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
TimescaleDB can be accessed via port 5432 on the following DNS name from within your cluster:
tsdb.default.svc.cluster.local
To get your password for superuser run:
# superuser password
PGPASSWORD_POSTGRES=$(kubectl get secret --namespace default tsdb-credentials -o jsonpath="{.data.PATRONI_SUPERUSER_PASSWORD}" | base64 --decode)
# admin password
PGPASSWORD_ADMIN=$(kubectl get secret --namespace default tsdb-credentials -o jsonpath="{.data.PATRONI_admin_PASSWORD}" | base64 --decode)
To connect to your database, chose one of these options:
1. Run a postgres pod and connect using the psql cli:
# login as superuser
kubectl run -i --tty --rm psql --image=postgres \
--env "PGPASSWORD=$PGPASSWORD_POSTGRES" \
--command -- psql -U postgres \
-h tsdb.default.svc.cluster.local postgres
# login as admin
kubectl run -i --tty --rm psql --image=postgres \
--env "PGPASSWORD=$PGPASSWORD_ADMIN" \
--command -- psql -U admin \
-h tsdb.default.svc.cluster.local postgres
2. Directly execute a psql session on the master node
MASTERPOD="$(kubectl get pod -o name --namespace default -l release=tsdb,role=master)"
kubectl exec -i --tty --namespace default ${MASTERPOD} -- psql -U postgres

TimescaleDB can be accessed via port 5432 on the following DNS name from within your cluster:
tsdb-mn-timescaledb.default.svc.cluster.local
To get your password for superuser run:
# superuser password
PGPASSWORD_SUPERUSER=$(kubectl get secret --namespace default tsdb-mn-timescaledb -o jsonpath="{.data.password-superuser}" | base64 --decode)
# admin password
PGPASSWORD_ADMIN=$(kubectl get secret --namespace default tsdb-mn-timescaledb -o jsonpath="{.data.password-admin}" | base64 --decode)
To connect to your database:
1. Run a postgres pod and connect using the psql cli:
# login as superuser
kubectl run -i --tty --rm psql --image=postgres \
--env "PGPASSWORD=$PGPASSWORD_SUPERUSER" \
--command -- psql -U postgres \
-h tsdb-mn-timescaledb.default.svc.cluster.local postgres
# login as admin
kubectl run -i -tty --rm psql --image=postgres \
--env "PGPASSWORD=$PGPASSWORD_ADMIN" \
