part 3

1. create 3 aws instances named as follows(hostname too)

	- manager
	- node1
	- node2

2. initialise docker swarm on the manager instanse

3. add node1 & node2 instances to the swarm as worker nodes

4. create a new overlay network named web-network

5. create a service to run on the swarm with following config

	- set name of the service as srv1
	- publish the port as *:8000->80
	- use web-network for the service as network
	- use mitrasonu/dsapp:1 image
        - replicas 3
        - update existing srv1 to image mitrasonu/dsapp:2

6. create a service to run on the swarm with following config

	- set name of the service as srv2
	- use web-network for the service as network
	- publish the port as *:8080->80
	- configure service to only run on node2
	- limit RAM usage to 200MB
	- limit CPUs ot .3
	- use mitrasonu/dsapp:1 image
        - replicas 2

7. create a new aws instance named manager2(hostname too)

8. join manager2 to the swarm as a manager node

9. scale service srv1 to 6

10. update availability of node2 to pause

11. scale service srv2 to 4

12. update availability of manager to drain

13. create a new overlay network named web-network2

14. create a service (global ) to run on the swarm with following config

	- set name of the service as gsrv
	- publish the port as *:8090->80
	- use web-network2 for the service as network
	- use mitrasonu/dsapp:1 image

15. Monitor Docker Swarm Cluster using Docker Swarm Visualizer tool
