No interruption. # Why Sometimes we need an Amazon EC2 instance with static fixed IP for testing or development purpose for a duration of time(probably hours). We need to make sure during this time, no interruption will occur and we don't want to pay for on-demand rate. `cdk-spot-one` helps you reserve one single spot instance with pre-allocated or new Elastic IP addresses(EIP) with defined `blockDuration`, during which time the spot instance will be secured with no spot interruption. Behind the scene, `cdk-spot-one` provisions a spot fleet with capacity of single instance for you and it associates the EIP with this instance. The spot fleet is reserved as spot block with `blockDuration` from one hour up to six hours to ensure the high availability for your spot instance. Multiple spot instances are possible by simply specifying the `targetCapacity` construct property, but we only associate the EIP with the first spot instance at this moment. Enjoy your highly durable one spot instance with AWS CDK! # Sample ```python # Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826 from cdk_spot_one import SpotFleet # create the first fleet for one hour and associate with our existing EIP fleet = SpotFleet(stack, "SpotFleet") # configure the expiration after 1 hour fleet.expire_after(Duration.hours(1)) # create the 2nd fleet with single Gravition 2 instance for 6 hours and associate with new EIP fleet2 = SpotFleet(stack, "SpotFleet2", block_duration=BlockDuration.SIX_HOURS, eip_allocation_id="eipalloc-0d1bc6d85895a5410", default_instance_type=InstanceType("c6g.large"), vpc=fleet.vpc ) # configure the expiration after 6 hours fleet2.expire_after(Duration.hours(6)) # print the instanceId from each spot fleet CfnOutput(stack, "SpotFleetInstanceId", value=fleet.instance_id) CfnOutput(stack, "SpotFleet2InstanceId", value=fleet2.instance_id) ``` # Create spot instances without duration block ```python # Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826 fleet = SpotFleet(stack, "SpotFleet", block_duration=BlockDuration.NONE ) ``` NOTE: This kind of spot instance will be interrupted by AWS. However the fleet is using type [maintain](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet.html#spot-fleet-allocation-strategy), the fleet can be refulfilled. # ARM64 and Graviton 2 support `cdk-spot-one` selects the latest Amazon Linux 2 AMI for your `ARM64` instances. Simply select the instance types with the `defaultInstanceType` property and the `SpotFleet` will auto configure correct AMI for the instance. ```python # Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826 defaultInstanceType: new InstanceType('c6g.large') ``` # SSH connect By default the `cdk-spot-one` does not assign any SSH public key for you on the instance. You are encouraged to use `ec2-instance-connect` to send your public key from local followed by one-time SSH connect. For example: ```sh pubkey="$HOME/.ssh/aws_2020_id_rsa.pub" echo "sending public key to ${instanceId}" aws ec2-instance-connect send-ssh-public-key --instance-id ${instanceId} --instance-os-user ec2-user \ --ssh-public-key file://${pubkey} --availability-zone ${az} ``` You may also create a simple `ec2-connect.sh` script like this and save in your $PATH: ```sh #!/bin/bash instanceId=$1 pubkey="$HOME/.ssh/aws_2020_id_rsa.pub" sshUser='ec2-user' az=$(aws ec2 describe-instances --instance-id ${instanceId} --query 'Reservations[0].Instances[0].Placement.AvailabilityZone' --output text) publicIp=$(aws ec2 describe-instances --instance-id ${instanceId} --query 'Reservations[0].Instances[0].PublicIpAddress' --output text) echo "sending public key to ${instanceId}" aws ec2-instance-connect send-ssh-public-key --instance-id ${instanceId} --instance-os-user ${sshUser} \ --ssh-public-key file://${pubkey} --availability-zone ${az} > /dev/null if [[ $2 != '--send-key-only' ]]; then echo "connecting to ${publicIp} at ${az}" ssh ${sshUser}@${publicIp} fi ``` And simply run this to connect to the EC2 instance. ```sh $ ec2-connect.sh i-01f827ab9de7b93a9 ``` It's also possible to explicitly specify your existing SSH key with the `keyName` construct property if you like.
