nginx-tomcat-containerisation

Steps to run:

• clone the repo
• ./start.sh
  • will build the docker images for nginx and tomcat.
  • will deploy the pods for nginx and tomcat.
• access the nginx at https://<ip_of_host_vm>:8443
• access the tomcat application at http://<ip_of_host_vm>:8080/hello-world/

Scaling:

• Use the helm config to increase the replicas (currently set to 3), so a particular request can go to any of the 3 pods running for nginx / tomcat.

What else can be done:

• We can add liveness and readiness probe to check the health of the services running, expose some API's like /healthz and that can be configured as part of helm configuration.

*Note: For the assignment purpose I have checked in the secrets into Git repo, which is not the ideal scenario, they should be deployed by devops person into the cluster manually.
