I created kubenertes secret
echo -n 'myusername' > username.txt
echo -n 'pa55word' > password.txt
kubectl create secret generic esb-database-secret-vol --from-file=username.txt --from-file=password.txtI created pod manifest as
spec:
containers:
- image: data-api-0.0.1.jar
ports:
- containerPort: 8080
name: esb-data-api
imagePullPolicy: Never
resources: {}
volumeMounts:
- name: esb-secret-vol
mountPath: "/etc/confidential"
readOnly: true
volumes:
- name: esb-secret-vol
secret:
secretName: esb-database-secret-volI verified that secrets now available in pod /etc/confidential folder
How does these values be available in application.properties so that I can get DB connection
spring.datasource.url=jdbc:sqlserver://mycompany.com;databaseName=My_DB
# need to read from /etc/confidential/username.txt
spring.datasource.username=??????
# need to read from /etc/confidential/password.txt
spring.datasource.password=??????
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriverYou have several options:
The first approach would look like
echo 'spring.datasource.username=myusername' >> app.properties
echo 'spring.datasource.password=pa55word' >> app.properties
kubectl create secret generic esb-database-secret-vol --from-file=app.propertiesYou would later mount the secret as application.properties in the container.
