I thought i did when I created the Dockerfile for the web application
docker image that I pushed to the google container registry and then listed
it in my web application kubernetes depolyment yaml file :
FROM tomcat:8-jre8
ADD sample.war /usr/local/tomcat/webapps/
CMD ["catalina.sh", "run"]
--------------------------
spec:
containers:
- image: gcr.io/projectid/web-application-image:v
<http://gcr.io/projectid/demo:v1>
name: web-pod
ports:
- containerPort: 8080
volumeMounts:
- name: persistent-storage
mountPath: /usr/local/tomcat/webapps
volumes:
- name: persistent-storage
persistentVolumeClaim:
claimName: web-pv-claim
