Deployment on aws:
WHEN YOU WANT TO DEPLOYED APP FROM
SCRATCH:
Now we are able to do deployment on aws. Now going to your
project directory and run following commands and answer the question asked by aws.
1. Run command èb init` in your terminal of your project. After running its ask some questions
like if your àws key` or àws secret` is not set you need to enter first those credentials.
1a. Select a default region
1) us-east-1 : US East (N. Virginia)
2) us-west-1 : US West (N. California)
3) us-west-2 : US West (Oregon)
4) eu-west-1 : EU (Ireland)
5) eu-central-1 : EU (Frankfurt)
6) ap-south-1 : Asia Pacific (Mumbai)
7) ap-southeast-1 : Asia Pacific (Singapore)
8) ap-southeast-2 : Asia Pacific (Sydney)
9) ap-northeast-1 : Asia Pacific (Tokyo)
10) ap-northeast-2 : Asia Pacific (Seoul)
11) sa-east-1 : South America (Sao Paulo)
12) cn-north-1 : China (Beijing)
13) cn-northwest-1 : China (Ningxia)
14) us-east-2 : US East (Ohio)
15) ca-central-1 : Canada (Central)
16) eu-west-2 : EU (London)
17) eu-west-3 : EU (Paris)
(default is 3):

Now enter the number for the region where you want to deploy your app.
1b. Select an application to use
1) staging-dragonboat-admin
2) dragonboat
3) [ Create new Application ]
(default is 2):
Now enter the number which application do you want to use or you want

1c. Enter Application Name
(default is "dragonboat2"): dragonboat-Testing

default name
1d. It appears you are using Node.js. Is this correct?
(Y/n): Y
Its will ask you about the language which you are using if you are
deploying the node it will ask you about node or if your deploying rails or any
other it will ask you about that.
1e. Note: Elastic Beanstalk now supports AWS CodeCommit; a fully-
managed source control service. To learn more, see Docs:
https://aws.amazon.com/codecommit/
Do you wish to continue with CodeCommit? (y/N) (default is n): n
If you have some changes and commit it you can procced with or just enter n
It will deploy the code which is last pushed on your branch
1f. Do you want to set up SSH for your instances?
(Y/n): Y
Ssh key needed if you want to check in in your aws server and want to check
your code If you will not setup ssh key you can never checkin server on aws and

So you have to create an environment on aws so Just run
2. `eb create enviroment_name` it will create environment for your application and
deploy it on aws. It will take 5 to 10 mints or may be little more time [LAUGH].
NOTE:
These steps are needed when you don’t have
any application on aws or never deploy before.
WHEN YOU HAVE ALREADY DEPLOYED APP
If you have already application on aws and want to deploy in it. And now to deploy latest
