CLI for service generation

[singhalkarun]

A CLI that takes important attributes of a service and adds it in the docker-compose.yaml file (if docker-compose.yaml doesn't exists, it creates a docker-compose.yaml)

SERVICE_NAME
IMAGE_URL
MEM_LIMIT
REPLICAS
ENVIRONMENT: a:b c:d e:f
VOLUMES

Service attributes will be very similar to what we had in K8S.

1. Onboard a service
2. Expose a service using caddy - (service name, service port) - Add an entry to Caddyfile (if it doesn't exist create it)

[singhalkarun]

Skipping ENVIRONMENT: a:b c:d e:f and VOLUMES for now.

[singhalkarun]

• don't allow adding service on root level, only allow inside a folder
• if the folder doesn't exist, create a folder and add service inside it
