Patroni can be accessed via port 5432 on the following DNS name from within your cluster:
2+
{{ template "patroni.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
3+
4+
To get your password for superuser run:
5+
6+
# superuser password
7+
PGPASSWORD_SUPERUSER=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "patroni.fullname" . }} -o jsonpath="{.data.password-superuser}" | base64 --decode)
8+
9+
# admin password
10+
PGPASSWORD_ADMIN=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "patroni.fullname" . }} -o jsonpath="{.data.password-admin}" | base64 --decode)
11+
12+
To connect to your database:
13+
14+
1. Run a postgres pod and connect using the psql cli:
15+
# login as superuser
16+
kubectl run -i --tty --rm psql --image=postgres \
17+
--env "PGPASSWORD=$PGPASSWORD_SUPERUSER" \
18+
--command -- psql -U postgres \
19+
-h {{ template "patroni.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local postgres
20+
21+
# login as admin
22+
kubectl run -i -tty --rm psql --image=postgres \
23+
--env "PGPASSWORD=$PGPASSWORD_ADMIN" \
24+
--command -- psql -U admin \
25+
-h {{ template "patroni.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local postgres
