I have built a tomcat image using the following dockerfile



FROM tomcat
COPY data-core.war /usr/local/tomcat/webapps/


then I built it using



docker build --no-cache -t tomcat:war .


Now how do I link a container based off this image with another container having mysql installed in it.Iam not really sure how the tomcat container can interact with the mysql database container.

Then finally i want to deploy/overlay this using kubernetes using the following yaml files for deployment and service.



1) deployment.yaml



apiVersion: apps/v1
kind: Deployment
metadata:
name: tomcat-deployment
labels:
app: tomcat
spec:
replicas: 1
selector:
matchLabels:
app: tomcat
template:
metadata:
labels:
app: tomcat
spec:
containers:
- name: tomcat
image: <REGISTRY>/<IMAGE>:<TAG>
ports:
- containerPort: 8080


2) service.yaml



kind: Service
apiVersion: v1
metadata:
name: tomcat-service
spec:
selector:
app: tomcat
ports:
- protocol: TCP
port: 80
targetPort: 8080
