Free Tier EC2 instance in eu-west-2

• t2.micro: 1vCPU, 1GB RAM. 0.013 USD per hour

Launch an instance

With a name-id MyInstanceName to help identify in e.g., console

aws ec2 run-instances --image-id "${ami_id}" --count 1 --instance-type "${instance_type}" --key-name "${key_pair}" --security-group-ids "${security_group}" --subnet-id "${subnet_id} --tag-specifications 'ResourceType=instance,Tags=[{Key=Name,Value=MyInstanceName}]'"

Terminate an instance

Replace terminate-instances with stop-instances if only stopping is needed.

aws ec2 terminate-instances --instance-ids i-5203422c

Add a block device to the image

When used with run-instances, example to provision a standard Amazon EBS volume that is 20 GB in size, and maps it to your instance using the identifier /dev/sdf:

--block-device-mappings "[{\"DeviceName\":\"/dev/sdf\",\"Ebs\":{\"VolumeSize\":20,\"DeleteOnTermination\":false}}]"

Add a tag to the instance

aws ec2 create-tags --resources i-5203422c --tags Key=Name,Value=MyInstance

List instances

• By type t2.micro, query instance id

aws ec2 describe-instances --filters "Name=instance-type,Values=t2.micro" --query "Reservations[].Instances[].InstanceId"

Returns ID: [ "i-05e998023d9c69f9a" ]

Query instance State (running, stopped, etc)

aws ec2 describe-instances --filters "Name=instance-type,Values=t2.micro" --query "Reservations[].Instances[].State[].Name"

• By tag Name=MyInstance:

aws ec2 describe-instances --filters "Name=tag:Name,Values=MyInstance"

• By AMI used to launch, e.g., ami-x0123456,ami-y0123456,ami-z0123456

aws ec2 describe-instances --filters "Name=image-id,Values=ami-x0123456,ami-y0123456,ami-z0123456"

List public IP of instances

E.g., to ssh into it. Can be filtered by id or state

aws ec2 describe-instances \
  --query "Reservations[*].Instances[*].PublicIpAddress" \
  --output=text
