Take an example of running psql to load DB schema:
template:
spec:
volumes:
- name: leaderboard-schema
configMap:
name: leaderboard-schema
items:
- key: schema.sql
path: schemas/schema.sql
containers:
- name: pgsql12-client
image: quay.io/rhdevelopers/openshift-pgsql12-primary:centos7-clients
imagePullPolicy: Always
env:
- name: PGHOST
value: postgresql
- name: PGDATABASE
valueFrom:
secretKeyRef:
name: openshift-pgsql12-primary-secret
key: database-db
- name: PGUSER
valueFrom:
secretKeyRef:
name: openshift-pgsql12-primary-secret
key: database-username
- name: PGPASSWORD
valueFrom:
secretKeyRef:
name: openshift-pgsql12-primary-secret
key: database-username-password
command: ["/usr/pgsql-12/bin/psql"]
args:
[
"--dbname=$(PGDATABASE)",
"--file=/opt/sql/schemas/schema.sql",
"--no-password",
]
volumeMounts:
- name: leaderboard-schema
mountPath: /opt/sql
for variable PGDATABASE
to be interpolated in command args we need to use the syntax "--dbname=$(PGDATABASE)"
