1. 
Launch instance from previous AMI

aws ec2 run-instances --image-id ami-0c960f6776affb006 --count 1 --instance-type t2.micro --key-name rj-tester-key --security-group-ids sg-0ed5b9b7488b55819 --query 'Instances[*].InstanceId' --output text

    i-0e1eb67ceab6866a0

2. 
Get the instance ip

aws ec2 describe-instances --instance-ids i-0e1eb67ceab6866a0 --query 'Reservations[*].Instances[*].PublicIpAddress' --output text

    3.96.147.75

2.
Get into the Machine by using SSH

ssh ubuntu@3.96.147.75 | yes

http://3.96.147.75:5000/

ssh -o StrictHostKeyChecking=no ubuntu@3.96.147.75

ssh -o StrictHostKeyChecking=no ubuntu@3.96.147.75 && bash -c 'pwd ; dir && ls'

ssh -o StrictHostKeyChecking=no ubuntu@3.96.147.75 bash -c 'pwd; cd /home/ubuntu/sc2base/simple-flask && git pull'

3. 
Create image from running instance

aws ec2 create-image \
    --instance-id i-0e1eb67ceab6866a0 \
    --name "anyone-clock-v1-5-ami" \
    --description "anyone-clock-v1-5-ami"


aws ec2 create-image --instance-id i-0e1eb67ceab6866a0 --name "anyone-clock-v1-5-ami" --description "anyone-clock-v1-5-ami"

        {
            "ImageId": "ami-0ff6d2d9a3bc69eb1"
        }

aws ec2 create-image \
    --instance-id i-0e1eb67ceab6866a0 \
    --name "rj-simple-flask-v1-1-ami" \
    --description "rj-simple-flask-v1-1-ami" \
