Launch AWS EC2 instance using awscli

Prepare environment: Install Required libraries.

virtualenv SaltStack
source SaltStack/bin/activate
pip install salt
pip install apache-libcloud
pip install awscli

created a new user in AWS console using Identity Management console

testuser
Access Key ID:
ABCDEFGHIJKLMNO235M
Secret Access Key:
aVeBUeixIlt1ScfseCV344NMnrx4fecNnex9mNNmjyjWv

Note: Above Key ID and Access Key are replaced with junk vales and will not work.
Above user “testuser” was added to AdministratorAccess policy in IAM (identity access management) in AWS console (Web interface).

In order to spin new instance and to be able to connect to them afterwards , we need a key pair. Either we can generate a new pair and upload it to AWS or generate it in AWS console (web interface) itself. In my case I had already generated the KeyPair. This key pair is called as “MyEC2Key”. This can be viewed under “compute” -> “EC2” -> “Key Pair"
Now create a “Security Group” that will allow ssh.

aws ec2 create-security-group --group-name MySecurityGroupSSHOnly --description "Inbound SSH"
aws ec2 authorize-security-group-ingress --group-name MySecurityGroupSSHOnly --cidr 0.0.0.0/0 --protocol tcp --port 22

Following command will spin a FREE TIER instance in AWS cloud

aws ec2 run-instances --image-id ami-9d23aeea --key-name MyEC2Key --instance-type t2.micro --count 1 --security-groups MySecurityGroupSSHOnly
